The Hymenoptera standing at the head of the Articulata, and the Mammalia at the head of the Vertebrata, it is curious to mark how, in geological history, the appearance and development of these two orders (culminating, one in the Ants; the other in the Primates) run parallel. The Hymenoptera and the Mammalia both make their first appearance early in the secondary period, and it is not until the commencement of the tertiary epoch that ants and monkeys appear upon the scene. There the parallel ends. No one species of ant has attained any great superiority above all its fellows, whilst man is very far in advance of all the other Primates.

When we see these intelligent insects dwelling together in orderly communities of many thousands of individuals, their social instincts developed to a high degree of perfection, making their marches with the regularity of disciplined troops, showing ingenuity in the crossing of difficult places, assisting each other in danger, defending their nests at the risk of their own lives, communicating information rapidly to a great distance, making a regular division of work, the whole community taking charge of the rearing of the young, and all imbued with the strongest sense of industry, each individual labouring not for itself alone but also for its fellows—we may imagine that Sir Thomas More's description of Utopia might have been applied with greater justice to such a community than to any human society. "But in Utopia, where every man has a right to everything, they do all know that if care is taken to keep the public stores full, no private man can want anything; for among them there is no unequal distribution, so that no man is poor, nor in any necessity, and though no man has anything, yet they are all rich; for what can make a man so rich as to lead a serene and cheerful life, free from anxieties, neither apprehending want himself, nor vexed with the endless complaints of his wife? He is not afraid of the misery of his children, nor is he contriving how to raise a portion for his daughters, but is secure in this, that both he and his wife, his children and grandchildren, to as many generations as he can fancy, will all live both plentifully and happily."

AFTER breakfast we again continued our voyage up the river, and passed the mouth of the San Carlos, another large stream running down from the interior of Costa Rica. Soon after we heard some wild pigs (Dicoteles tajacu) or Wari, as they are called by the natives, striking their teeth together in the wood, and one of the boatmen leaping on shore soon shot one, which he brought on board after cutting out a gland on its back that emits a musky odour, and we afterwards had it cooked for our dinner. These Wari go in herds of from fifty to one hundred. They are said to assist each other against the attacks of the jaguar, but that wary animal is too intelligent for them. He sits quietly upon a branch of a tree until the Wari come underneath; then jumping down kills one by breaking its neck; leaps up into the tree again and waits there until the herd depart, when he comes down and feeds on the slaughtered Wari in quietness. We shortly afterwards passed one of the large boats called bungos, that carry down to Greytown the produce of the country and take up merchandise and flour. This one was laden with cattle and india-rubber. The bungos are flat-bottomed boats, about forty feet long and nine feet wide. There is generally a little cabin, roofed over at the stern, in which the wife of the captain lives. The bungo is poled along by twelve bungo-men, who have usually only one suit of clothes each, which they do not wear during the day, but keep stowed away under the cargo that it may be dry to put on at night. Their bronzed, glistening, naked bodies, as they ply their long poles together in unison, and chant some Spanish boat-song, is one of the things that linger in the memory of the traveller up the San Juan. Our boatmen paddled and poled until eleven at night, when we reached Machuca, a settlement consisting of a single house, just below the rapids of the same name, seventy-miles above Greytown.

We breakfasted at Machuca before starting next morning, and I walked up round the rapids and met the canoe above them. About five o'clock, after paddling all day, we came in sight of Castillo, where there is an old ruined Spanish fort perched on the top of a hill overlooking the little town, which lies along the foot of the steep hill; hemmed in between it and the river, so that there is only room for one narrow street. It was near Castillo that Nelson lost his eye. He took the fort by landing about half a mile lower down the river, and dragging his guns round to a hill behind it by which it was commanded. This hill is now cleared of timber and covered with grass, supporting a few cows and a great many goats. In front of the town run the rapids of Castillo, which are difficult to ascend, and as there is no road round them excepting through the town of Castillo, advantage has been taken of the situation to fix the custom-house there, where are collected the duties on all articles going up to the interior. The first view of Castillo when coming up the river is a fine one. The fort-crowned hill and the little town clinging to its foot form the centre of the picture. The clear, sparkling, dancing rapids on one side contrast with the still, dark forest on the other, whilst the whole is relieved by the bright green grassy hills in the background. This view is the only pleasant recollection I have carried away of the place. The single street is narrow, dirty, and rugged, and when the shades of evening begin to creep up, swarms of mosquitoes issue forth to buzz and bite.

I here made the acquaintance of colonel McCrae, who was largely concerned in the india-rubber trade. He afterwards distinguished himself during the revolutionary outbreak of 1869. He collected the rubber men and came to the assistance of the government, helping greatly to put down the insurrection. Originally a British subject, but now a naturalised Nicaraguan, he has filled with great credit for some time the post of deputy-governor of Greytown, and I always heard him spoken of with great esteem both by Nicaraguans and foreigners. He showed to me pieces of cordage, pottery, and stone implements brought down by the rubber men from the wild Indians of the Rio Frio. Castillo is one of the centres of the rubber trade. Parties of men are here fitted out with canoes and provisions, and proceed up the rivers, far into the uninhabited forests of the Atlantic slope. They remain for several months away, and are expected to bring the rubber they obtain to the merchants who have fitted them out, but very many prove faithless, and carry off their produce to other towns, where they have no difficulty in finding purchasers. Notwithstanding these losses, the merchants engaged in the rubber trade have done well; its steadily increasing value during the last few years having made the business a highly remunerative one. According to the information supplied to me at Greytown by Mr. Paton, the exports of rubber from that port had increased from 401,475 pounds, valued at 112,413 dollars, in 1867, to 754,886 pounds, valued at 226,465 dollars, in 1871. India-rubber was well-known to the ancient inhabitants of Central America. Before the Spanish conquest the Mexicans played with balls made from it, and it still bears its Aztec name of Ulli, from which the Spaniards call the collectors of it Ulleros. It is obtained from quite a different tree, and prepared in a different manner, from the rubber of the Amazons. The latter is taken from the Siphonia elastica, a Euphorbiaceous tree; but in Central America the tree that yields it it is a species of wild fig (Castilloa elastica). It is easily known by its large leaves, and I saw several whilst ascending the river. When the collectors find an untapped one in the forest, they first make a ladder out of the lianas or "vejuccos " that hang from every tree; this they do by tying short pieces of wood across them with small lianas, many of which are as tough as cord. They then proceed to score the bark, with cuts which extend nearly round the tree like the letter V, the point being downwards. A cut like this is made about every three feet all the way up the trunk. The milk will all run out of a tree in about an hour after it is cut, and is collected into a large tin bottle made flat on one side and furnished with straps to fix on to a man's back. A decoction is made from a liana (Calonyction speciosum), and this on being added to the milk, in the proportion of one pint to a gallon, coagulates it to rubber, which is made into round flat cakes. A large tree, five feet in diameter, will yield when first cut about twenty gallons of milk, each gallon of which makes two and a half pounds of rubber. I was told that the tree recovers from the wounds and may be cut again after the lapse of a few months; but several that I saw were killed through the large Harlequin beetle (Acrocinus longimanus) laying its eggs in the cuts, and the grubs that are hatched boring great holes all through the trunk. When these grubs are at work you can hear their rasping by standing at the bottom of the tree, and the wood-dust thrown out of their burrows accumulates in heaps on the ground below. The government attempts no supervision of the forests: any one may cut the trees, and great destruction is going on amongst them through the young ones being tapped as well as the full-grown ones. The tree grows very quickly, and plantations of it might easily be made, which would in the course of ten or twelve years become highly remunerative.

We left Castillo at daylight the next morning, and continued our journey up the river. Its banks presented but little change. We saw many tall graceful palms and tree ferns, but most of the trees were dicotyledons. Amongst these the mahogany (Swietonia mahogani) and the cedar (Cedrela odorata) are now rare near the river, but a few such trees were pointed out to me. High up in one tree, underneath which we passed, were seated some of the black congo monkeys (Mycetes palliatus) which at times, especially before rain and at nightfall, make a fearful howling, though not so loud as the Brazilian species. Screaming macaws, in their gorgeous livery of blue, yellow, and scarlet, occasionally flew overhead, and tanagers and toucans were not uncommon.

Twelve miles above Castillo we reached the mouth of the Savallo, and stayed at a house there to breakfast, the owner, a German, giving us roast wari, fowls, and eggs. He told me that there was a hot spring up the Savallo, but I had not time to go and see it. Above Savallo the San Juan is deep and sluggish, the banks low and swampy. The large palm, so common in the delta of the river, here reappeared with its great coarse leaves twenty feet in length, springing from near the ground.

Our boatmen continued to paddle all day, and as night approached redoubled their exertions, singing to the stroke of their paddles. I was astonished at their endurance. They kept on until eleven o'clock at night, when we reached San Carlos, having accomplished about thirty-five miles during the day against the current. San Carlos is at the head of the river, where it issues from the great lake of Nicaragua, about one hundred and twenty miles from Greytown. The mean level of the waters of the lake, according to the survey of Colonel O.W. Childs, in 1851, is 107 1/2 feet, so that the river falls on an average a little less than one foot per mile. The height of the lowest pass between the lake and the Pacific is said to be twenty-six feet above the lake, therefore at that point the highest elevation between the two oceans is only about 133 feet; but even allowing that an error of a few feet may be discovered when a thorough survey is made across from sea to sea, there can be no doubt that at this point occurs the lowest pass between the Atlantic and the Pacific in Central America. This fact, and the immense natural reservoir of water near the head of the navigation, point out the route as a practicable one for a ship canal between the two oceans.

Instead of cutting a canal from the head of the delta of the San Juan to the sea, as has been proposed, the Colorado branch might be straightened, and dredged to the required depth. Higher up, the Torre, Castillo, and Machuca Rapids form natural dams across the river. These might be raised, locks formed round them, and the water deepened by dredging between them. In this way the great expense of cutting a canal, and the fearful mortality that always arises amongst the labourers when excavations are made in the virgin soil of the tropics, especially in marshy lands, would be greatly lessened between the lake and the Atlantic. Another great advantage would be that the deepening of the river could be effected by steam power, so that it would not be necessary to bring such a multitude of labourers to the isthmus as would be required if a canal were cut from the river; the whole track, moreover, passes through virgin forests rich in inexhaustible supplies of fuel.* (* The commission appointed by the United States Government to examine into the practicability of making a canal across the isthmus reported in favour of the Nicaraguan route, and the work was begun at Greytown in 1889. But after an expenditure of 4,500, 000 dollars, the scheme was abandoned, for political reasons, in favour of the Panama route.)

San Carlos is a small town at the foot of the great lake, where it empties its waters into the San Juan river, its only outlet to the ocean. On a hill behind the town, and commanding the entrance to the river, are the ruins of a once strong fort built by the Spaniards, the crumbling walls now green with the delicate fronds of a maiden hair fern (Adiantum). The little town consists of a single rugged street leading up from the lake. The houses are mostly palm-thatched huts, with the bare earth floors seldom or never swept. The people are of mixed origin, Indian, Spanish, and Negro, the Indian element predominating. Two or three better built stores, and the quarters of the military governor, redeem the place from an appearance of utter squalor. Behind the town there are a few small clearings in the forest, where maize is grown. Some orange, banana, and plantain trees exhaust the list of the productions of San Carlos, which is supported by being a calling place for all vessels proceeding up and down the river, and by the Ulleros or rubber-men who start from it for expeditions up the Rio Frio and other rivers. We found there two men who had just been brought down the Rio Frio by their companions, greatly injured, by the lianas up which they had made their ladder to ascend one of the rubber trees, having broken and precipitated them to the ground. I learnt that this was a very unusual accident, the lianas generally being very tough and strong, like great cables.

Most fabulous stories have been told about the Rio Frio and its inhabitants; stories of great cities, golden ornaments, and light-haired people, and it may be useful to relate what is known about it.

The Rio Frio comes down from the interior of Costa Rica, and joins the San Juan, near where the latter issues from the lake. The banks of its upper waters are inhabited by a race of Indians who have never been subjugated by the Spaniards, and about whom very little is known. They are called Guatuses, and have been said to have red or light-coloured hair and European features, to account for which various ingenious theories have been advanced; but, unfortunately for these speculations, some children, and even adults, have been captured and brought down the river by the Ulleros, and all these have the usual features and coarse black hair of the Indians. One little child that Dr. Seemann and I saw at San Carlos, in 1870, had a few brownish hairs amongst the great mass of black ones; but this character may be found amongst many of the indigenes, and may result from a very slight admixture of foreign blood. I have seen altogether five children from the Rio Frio, and a boy about sixteen years of age, and they had all the common Indian features and hair; though it struck me that they appeared rather more intelligent than the generality of Indians. Besides these, an adult woman was captured by the rubber-men and brought down to Castillo, and I was told by several who had seen her that she did not differ in any way from the usual Indian type.

The Guatuse (pronounced Watusa) is an animal about the size of a hare, very common in Central America, and good eating. It has reddish-brown fur, and the usual explanation of the Nicaraguans is that the Indians of the Rio Frio were called "Guatuses" because they had red hair. It is very common to find the Indian tribes of America called after wild animals, and my own opinion is that the origin of the fable about the red hair was a theory to explain why they were called Guatuses; for the natives of Nicaragua, and of parts much nearer home, are fond of giving fanciful explanations of the names of places and things: thus, I have been assured by an intelligent and educated Nicaraguan, that Guatemala was so-called by the Spaniards because they found the guate (a kind of grass) in that country bad, hence "guate malo," "bad guate,"—whereas every student of Mexican history knows that the name was the Spanish attempt to pronounce the old Aztec one of Quauhtemallan, which meant the Land of the Eagle. I shall have other occasions, in the course of my narrative, to show how careful a traveller in Central America must be not to accept the explanations of the natives of the names of places and things.

The first people who ascended the Rio Frio were attacked by the Indians, who killed several with their arrows. Exaggerated opinions of their ferocity and courage were in consequence for a long time prevalent, and the river remained unknown and unexplored, and probably would have done so to the present day, if it had not been for the rubber-men. When the trade in india-rubber became fully developed, the trees in the more accessible parts of the forest were soon exhausted, and the collectors were obliged to penetrate farther and farther back into the untrodden wilds of the Atlantic slope. Some more adventurous than others ascended the Rio Frio, and being well provided with fire-arms, which they mercilessly used, they were able to defy the poor Indians, armed only with spears and bows and arrows, and to drive them back into the woods. The first Ulleros who ascended the river were so successful in finding rubber, that various other parties were organised, and now an ascent of the Rio Frio from San Carlos is of common occurrence. The poor Indians are now in such dread of fire-arms, that on the first appearance of a boat coming up the river they desert their houses and run into the woods for shelter. The Ulleros rush on shore and seize everything that the poor fugitives have left behind them; and in some cases the latter have not been able to carry off their children, and these have been brought down in triumph to San Carlos. The excuse for stealing the children is that they may be baptised and made Christians; and I am sorry to say that this shameful treatment of the poor Indians is countenanced and connived at by the authorities. I was told of one commandante at San Carlos who had manned some canoes and proceeded up the river as far as the plantain grounds of the Indians, loaded his boats with the plantains, and brought them down to San Carlos, where the people appear to be too indolent to grow them themselves. All who have ascended the river speak of the great quantities of plantains that the Guatuses grow, and this fruit, and the abundant fish of the river, form their principal food. Their houses are large sheds open at the sides, and thatched with the "suiti" palm. As is often the case amongst the Indians, several families live in one house. The floor is kept well cleaned. I was amused with a lady in San Carlos who, in describing their well-kept houses to Dr. Seemann and myself, pointed to her own unswept and littered earth floor and said, "They keep their houses very, very clean—as clean as this." The lad and the woman who were captured and brought down the Rio Frio both ran away—the one from San Carlos, the other from Castillo; but neither could succeed in reaching home, on account of the swamps and rivers in their way, and after wandering about the woods for some time they were recaptured. I saw the lad soon after he was taken the second time. He had been a month in the woods, living on roots and fruits, and had nearly died from starvation. He had an intelligent, sharp, and independent look about him, and kept continually talking in his own language, apparently surprised that the people around him did not understand what he was saying. He was taken to Castillo, and met there the woman who had been captured a year before, and had learnt to speak a little Spanish. Through her as an interpreter, he tried to get permission to return to the Rio Frio, saying that if they would let him go he would come back and bring his father and mother with him. This simple artifice of the poor boy was, of course ineffectual. He was afterwards taken to Granada, for the purpose, they said, of being educated, that he might become the means of opening up communication with his tribe.

The rubber-men bring down many little articles that they pillage from the Indians. They consist of cordage, made from the fibre of Bromeliaceous plants, bone hooks, and stone implements. Amongst the latter, I was fortunate enough to obtain a rude stone hatchet, set in a stone-cut wooden handle: it was firmly fixed in a hole made in the thick end of the handle.* [* Figured in Evans' "Ancient Stone Implements" second edition page 155. In Evans' first edition it is erroneously stated in the text to be from Texas. It has been pointed out that early man adopted the opposite method to the modern in the mounting of his axes: we fix the handle into a hole in the axe head; he jammed the head into a hole in the handle.] It is a singular fact, and one showing the persistence of particular ways of doing things through long ages amongst people belonging to the same race, that, in the ancient Mexican, Uxmal, and Palenque picture-writings, bronze axes are represented fixed in this identical manner in holes at the thick ends of the handles.

We slept on board one of the steamers of the American Transit Company. It was too dark when we arrived at San Carlos to see anything that night of the great lake, but we heard the waves breaking on the beach as on a sea-shore, and from further away came that moaning sound that has from the earliest ages of history connected the idea of the sea with sorrow and sadness.* (* "There is sorrow on the sea; it cannot be quiet" Jeremiah 49:23.) The steamer we stayed in was one of four river-boats belonging to the Transit Company, which was at this time in difficulties, and ultimately the boats were sold; part of them being bought by Mr. Hollenbeck, and used by the navigation company which he established. These steamers are built expressly for shallow rivers, and are very different structures from anything we see in England. The bottom is made quite flat, and divided into compartments; the first deck being only about eighteen inches above the water, from which it is divided by no bulwarks or other protection. Upon this deck are placed the cargo and the driving machinery. A vertical boiler is fixed at the bow, and two horizontal engines, driving a large paddle-wheel, at the stern. The second deck is for passengers, and is raised on light wooden pillars braced with iron rods about seven feet above the first. Above this is another deck, on which are the cabins of the officers and the steering apparatus. The appearance of such a structure is more like that of a house than a boat. The one we were in, the "Panaloya," drew only three feet of water when laden with 400 passengers and twenty tons of cargo.

As daylight broke next morning, I was up, anxious to see the great lake about which I had heard so much. To the north-west a great sheet of quiet water extended as far as the eye could reach, with islands here and there, and—the central figure in every view of the lake—the great conical peak of Ometepec towered up, 5050 feet above the sea, and 4922 feet above the surface of the lake. To the left, in the dim distance, were the cloud-capped mountains of Costa Rica; to the right, nearer at hand, low hills and ranges covered with dark forests. The lake is too large to be called beautiful, and its vast extent and the mere glimpses of its limits and cloud-capped peaks appeal to the imagination rather than to the eye. At this end of the lake the water is shallow, probably filled up by the mud brought down by the Rio Frio.

We had still a voyage of sixty miles before us up the lake, and this was to be accomplished not by paddling, but by sailing; so we now rigged two light masts, and soon after seven o'clock sailed slowly away from San Carlos before a light breeze, which in an hour's time freshened and carried us along at the rate of about six miles an hour. The sun rose higher and higher; the day waxed hotter and hotter. About noon the wind failed us again, and the sun right overhead, in a clear pitiless sky, scorched us with its rays, while our boat lay like a log upon the water, the pitch melting in the seams with the heat. The surface of the lake was motionless, save for a gentle heaving. We were almost broiled with the stifling heat, but at last saw a ripple on the water come up from the north-east; soon the breeze reached us, and our torment was over; our sails, no more idly flapping, filled out before the wind; the canoe dashed through the rising waves; our drooping spirits revived, and there was an opening out of provisions, and life again in the boat. The breeze continued all the afternoon, and at dark we were off the islands of Nancital, having been all day within a few miles of the north-eastern side of the lake, the banks of which are everywhere clothed with dark gloomy-looking forests. One of the islands was a favourite sleeping-place for the white egrets. From all sides they were flying across the lake towards it; and as night set in, the trees and bushes by the water-side were full of them, gleaming like great white flowers amongst the dark green foliage. Flocks of muscovy and whistling ducks also flew over to their evening feeding-places. Great masses of a floating plant, shaped like a cabbage, were abundant on the lake, and on these the white egrets and other wading birds often alighted. The boatmen told me—and the story is likely enough to be true—that the alligators, floating about like logs, with their eyes above the water, watch these birds, and, moving quietly up until within a few yards of them, sink down below the surface, come up underneath them, catch them by the legs and drag them under water. Besides the alligators, large freshwater sharks appear to be common in the lake. Sometimes, when in shallow water, we saw a pointed billow rapidly moving away from the boat, produced by some large fish below, and I was told it was a shark.

After dark the wind failed us again, and we got slowly along, but finally reached our port, San Ubaldo, about ten o'clock, and found an officer of the mining company, living in a small thatched hut, stationed there to send on the machinery and other goods that arrived for the mines. A large tiled store had also just been built by the owner of the estate there, Don Gregorio Quadra, under the verandah of which I hung my hammock for the night. Mules were waiting at San Ubaldo for us, and early next morning we set off, with our luggage on pack mules. We crossed some rocky low hills, with scanty vegetation, and, after passing the cattle hacienda of San Jose, reached the plains of the same name, about two leagues in width, now dry and dusty, but in the wet season forming a great slough of water and tenacious mud, through which the mules have to wade and plunge.

In the midst of these plains there are some rocky knolls, like islands, on which grow spiny cactuses, low leathery-leaved trees, slender, spiny palms, with plum-like fruit, prickly acacias, and thorny bromelias. This spiny character of vegetation seems to be characteristic of dry rocky places and tracts of country liable to great drought. Probably it is as a protection from herbivorous animals, to prevent them browsing upon the twigs and small branches where herbaceous vegetation is dried up. Small armadillos abound near these rocky knolls, and are said to feed on ants and other insects. We had a long chase after one, which we observed some distance from the rock, over the cracked and dried-up plain: though it could not run very fast, it doubled quickly, and the rough cracked ground made odds in its favour; but it was ultimately secured. Pigeons, brown coloured, of various sizes, from that of a thrush to that of a common dove, were numerous and very tame. One of the smallest species alights and seeks about in the streets of small towns for seeds, like a sparrow, and more boldly than that bird, for it is not molested by the children—more perhaps from indolence than from any lack of the element of cruelty in their dispositions. After crossing the plains we rode over undulating hills, here called savannahs, with patches of forest on the rising ground, and small plains on which grows the ternate-leaved jicara (pronounced hickory), a tree about as large as an apple-tree, with fruit of the size, shape, and appearance of a large green orange, but growing on the trunk and branches, not amongst the leaves. The outside of the fruit is a hard thin shell, packed full of seeds in a kind of dry pulp, on which are fed fowls, and even horses and cattle in the dry season; the latter are said sometimes to choke themselves with the fruit, whilst trying to eat it. Of the bruised seeds is also made a cooling drink, much used in Nicaragua. The jicara trees grow apart at equal distances, as if planted by man. The hard thin shell of the fruit, carved in various patterns on the outside, is made into cups and drinking-vessels by the natives, who also cultivate other species of jicara, with round fruit, as large as a man's head, from which the larger drinking-bowls are made. In the smaller jicaras chocolate is always made and served in Central America, and, being rounded at the bottom, little stands are made to set them in; these are sometimes shaped like egg-cups, sometimes like toy washhand-stands. In making their earthenware vessels, the Indians up to this day follow this natural form, and their water-jars and bowls are made rounded at the bottom, requiring stands to keep them upright.

The meals of Montezuma were served on thick cushions or pillows. This was probably on account of the rounded bases of the bowls and dishes used. The gourd forms of bowls possibly originated from the clay being moulded over gourds which were burnt out in the baking process. It is said that in the Southern States the kilns in which the ancient pottery was baked have been found, and in some the half-baked ware remained, retaining the rinds of the gourds over which they had been moulded. Afterwards, when the potter learned to make bowls without the aid of gourds, he still retained the shape of his ancient pattern.

The name, too, like the form, has had a wonderful vitality. It is the "xicalli" of the ancient Aztecs, changed to "jicara" by the Spaniards, by which they mean a chocolate-cup; and even in Italy a modification of the same word may be heard, a tea-cup being called a chicchera.

On top of one of the hills we just got a glimpse of a small pack of wolves, or coyotes, as they are called, from the Aztec coyotl. They are smaller than the European wolf, and are cunning, like a fox, but hunt in packs. They looked down at us from the ridge of the hill for a few moments, then trotted off down the other side. Their howlings may often be heard in the early morning.

Cattle, horses, and mules are bred on these plains. Male asses are kept at some of the haciendas. They are not allowed to mix with any of their own kind, and are well fed and in good condition; but they are only of small size, and the breed of mules might be greatly improved by the introduction of larger asses.

The vegetation on the plains was rapidly drying up. Many of the trees shed their leaves in the dry season, just as they do with us in autumn. The barrenness of the landscape is relieved in March by several kinds of trees bursting into flower when they have shed their leaves, and presenting great domes of brilliant colour—some pink, others red, blue, yellow, or white, like single-coloured bouquets. One looked like a gigantic rhododendron, with bunches of large pink flowers. The yellow-flowered ones belong to wild cotton-trees, from the pods of which the natives gather cotton to stuff pillows, etc. About one o'clock we reached rather a large river, and after crossing it came in sight of the town of Acoyapo, one of the principal towns of the province of Chontales. we stayed and had dinner with Senor Don Dolores Bermudez, a Nicaraguan gentlemen who had been educated in the States, and spoke English fluently. He very kindly took me over the town, and I always found him ready to give me information respecting the antiquities and natural products of the country. Acoyapo and the district around it contains about two thousand inhabitants. The store-keepers, lawyers, and hacienderos are of Spanish and mixed descent. Amongst the lower classes there is much Indian and some negro blood; but there are many pure Indians scattered through the district, living near the rivers and brooks, and growing patches of maize and beans. In the centre of the town is a large square or plaza, with a stucco-fronted church occupying one side, and the principal stores and houses ranging around the other three sides. A couple of coco-palms grow in front of the church, but do not thrive like those near the sea-coast. It was Saturday, the 22nd of February, when we arrived; this was a great feast-day, or festa, at Acoyapo, and the town was full of country people, who were amusing themselves with horse-races, cock-fights, and drinking aguardiente. Their mode of cock-fighting is very cruel, as the cocks are armed with long sickle-shaped lancets, tied on to their natural spurs, with which they give each other fearful gashes and wounds. All classes of Nicaraguans are fond of this amusement; in nearly every house a cock will be found, tied up in a corner by the leg, but treated otherwise like one of the family. The priests are generally great abettors of the practice, which forms the usual amusement of the towns on Sunday afternoons. I have heard many stories of the padres after service hurrying off to the cock-pit with a cock under each arm. Bets are made on every fight, and much money is lost and won over the sport.

Like most of the Nicaraguan towns, Acoyapo appears to have been an Indian city before the Spanish conquest. The name is Indian, and in the plaza Senor Bermudez pointed out to me some flat bared rock surfaces, on which were engraved circles and various straight and curved characters, covering the whole face of the rock. Some rude portions of stone statues that have been found in the neighbourhood are also preserved in the town. The Spaniards called the town San Sebastian; but the more ancient name is likely to prevail, notwithstanding that in all official documents the Spanish one is used. Acoyapo is a grazing district, and there are some large cattle haciendas, especially towards the lake. The town suffers from fever owing to the neighbouring swamp. Much of the land around is very fertile; but little of it is cultivated, as the people are indolent, and content if they make a bare livelihood. We left Acoyapo about three o'clock: our road lay up the river, which we crossed three times. Excepting near the river, the country was very thinly timbered; and it was pleasant, after riding across the open plains, exposed to the hot rays of the sun, to reach the shady banks of the stream, by which grew many high thick-foliaged trees, with lianas hanging from them, and bromelias, orchids, ferns, and many other epiphytes perched on their branches. At these spots, too, were various beautiful birds, amongst which the Sisitote, a fine black and orange songster, and a trogon (Trogon malanocephalus, Gould), were the most conspicuous.

We reached and crossed a high range, from the summit of which we had a splendid view over the plains and savannahs we had crossed, to the great lake, with its islands and peaked hills, and beyond the dark dim mountains of Costa Rica, amongst which dwell the Indians of the Rio Frio and other little-known tribes. Before us were spread out well-grassed savannahs, thinly timbered, excepting where dark winding lines of trees or light green thickets of bamboos marked the course of rivers or mountain brooks. Here and there were dotted thatched huts, in which dwelt the owners of the cattle, mules, and horses feeding on the meadows. Far in the distance the view was bounded by a line of dark, nearly black-looking forest, which, there commencing, extends unbroken to the Atlantic. Near its edge, a seven-peaked range marked the neighbourhood of Libertad—the beginning of the gold-mining district. Descending the slope of the range, we found the savannahs on its eastern side much more moist than those to the westward of it; and as we proceeded, the humidity of the ground increased, and the crossings of some of the valleys and swamps were difficult for the mules. The dry season had set in, and these places were rapidly drying up; but in many it had just reached that stage when the mud was most tenacious; at one very bad crossing, called an "estero," my mule fell, with my leg underneath him, pinning me in the mud. The poor beast was exhausted, and would not move. Night had set in—it was quite dark, and I had lagged some distance behind my companions: fortunately they heard my shouts, and, soon returning, extricated me from my awkward predicament. Without further mishap we reached Esquipula, a village inhabited mostly by half-breeds, and slung our hammocks for the night in a small thatched house belonging to the mining company, who kept many of their draught bullocks at this place on account of the excellent pasture around. The village of Esquipula is built near the river Mico, which, rising in the forest-clad ranges to the eastward, runs for several miles through the savannahs, then again enters the forest and flows into the Atlantic at Blewfields, a broad and deep river. This river must have had at one time a large Indian population dwelling in settled towns near its banks. Their burial places, marked with great heaps of stones, are frequent, and pieces of pottery, broken stone statues, and pedestals are often met with. Near Esquipula there are some artificial-looking mounds, with great stones set around them; in fact, this and another village, a few miles to the south, called San Tomas, are, I believe, both built on the sites of old Indian towns. The Indians of the Rio Mico gave the Spaniards some trouble on their first settlement of the country. About two leagues from Acoyapo, the site of a small town was pointed out to me, now covered with low trees and brushwood. Here the Spaniards were attacked in the night-time by the Rio Mico Indians, and all of them killed, excepting the young women, who were carried off into captivity, and the place has ever since lain desolate.

Many extravagant stories have been told of the great statues that are said to have been seen on the banks of the Mico, much lower down the river than where we crossed it; but M. Etienne, of Libertad, who descended it to Blewfields, and some Ulleros of San Tomas, who had frequently been down it after india-rubber, assured me that the reported statues were merely rude carvings of faces and animals on the rocks. They appear to be similar to what are found on many rivers running into the Caribbean Sea, and to those which were examined by Schomburgk on the rocks of the Orinoco and Essequibo. As others like them, of undoubted Carib workmanship, have been found in the Virgin Islands, it is possible that they are all the work of that once-powerful race, and not of the settled agricultural and statue-making Indians of the western part of the continent.

We started from Esquipula early next morning, and crossed low thinly-timbered hills and savannahs to Pital, a scattered settlement of many small thatched houses, close to the borders of the great forest; on the edge of which were clearings, made for growing maize, which is cultivated entirely on burnt forest land. At some parts they had already commenced cutting down trees for fresh clearings; these would be burnt in April, and the maize sown the following month, in the usual primitive way, just as it was in Mexico before and at the Spanish conquest. In commencing a clearing, the brushwood is first cut close to the ground, as it would be difficult to do so after the large trees are felled. The big timber is then cut down, and in April it is set fire to. All the small wood and leaves burn well; but most of the large trunks are left, and many of the branches. Most of the latter are cut up to form a fence round the clearing, this at Pital and Esquipula being made very close and high to keep out deer. In May, the maize is sown; the sower makes little holes with a pointed stick, a few feet apart, into each of which he drops two or three grains, and covers them with his foot. In a few days the green leaves shoot up, and grow very quickly. Numerous wild plants also spring up, and in June these are weeded out; the success of the crop greatly depending upon the thoroughness with which this is done. In July each plant has produced two or three ears; and before the grain is set these are pulled off, excepting one, as if more are left they do not mature well. The young ears are boiled whole, and make a tender and much-esteemed vegetable. They are called at this stage "chilote," from the Aztec xilotl; and the ancient Mexicans in their eighth month, which began on the 16th July, made a great festival, called the feast of Xilonen. The poor Indians now have often reason to rejoice when this stage is reached, as their stores of corn are generally exhausted before then, and the "chilote" is the first fruits of the new crop. In the beginning of August the grains are fully formed, though still tender and white; and it is eaten as green corn, now called "elote." In September the maize is ripe, and is gathered when dry, and stowed away, generally over the rooms of the natives. A second crop is often sown in December.

Maize is very prolific, bearing a hundredfold, and ripening in April. From the most ancient times, maize has been the principal food of the inhabitants of the western side of tropical America. On the coast of Peru, Darwin found heads of it,* along with eighteen species of marine shells, in a raised beach eighty-five feet above the level of the sea (* "Geological Observations in South America" 1846 page 49 and "Animals and Plants under Domestication" volume 1 page 320.); and in the same country it has been found in tombs apparently more ancient than the earliest times of the Incas.* (*Von Tschudi "Travels in Peru" English edition page 177.) In Mexico it was known from the earliest times of which we have any record, in the picture writings of the Toltecs; and that ancient people carried it with them in all their wanderings. In Central America the stone grinders, with which they bruised it down, are almost invariably found in the ancient graves, having been buried with the ashes of the dead, as an indispensable article for their outfit for another world. When Florida and Louisiana were first discovered, the native Indian tribes all cultivated maize as their staple food; and throughout Yucatan, Mexico, and all the western side of Central America, and through Peru to Chili, it was, and still is, the main sustenance of the Indians. The people that cultivated it were all more or less advanced in civilisation; they were settled in towns; their traders travelled from one country to another with their wares; they were of a docile and tractable disposition, easily frightened into submission. It is likely that these maize-eating peoples belonged to closely affiliated races. In the West India Islands they occupied most of Cuba and Hayti; but from Porto Rico southwards the islands were peopled by the warlike Caribs, who harassed the more civilised tribes to the north. From Cape Gracias a Dios southward, the eastern coast of America was peopled on its first discovery by much ruder tribes, who did not grow maize, but made bread from the roots of the mandioca (Manihot aipim); and still in British Guiana, on the Lower Amazon, and in north-eastern Brazil, farina made from the roots of the mandioca is the staple food. Maize has been introduced by the Portuguese, but it has no native name, and is used mostly for feeding cattle and fowls, scarcely at all for the food of the people. This fundamental difference in the food of the indigenes points to a great distinction between the peoples to which I shall have in the sequel to revert. In the West India Islands, Cuba and Hayti seem to have been peopled from Yucatan, and Florida, Porto Rico, and all the islands to the southwards, from Venezuela.

In Central America, the bread made from the maize is prepared at the present day exactly as it was in ancient Mexico. The grain is first of all boiled along with wood ashes or a little lime; the alkali loosens the outer skin of the grain, and this is rubbed off with the hands in running water, a little of it at a time, placed upon a slightly concave stone, called a metlate, from the Aztec metlatl, on which it is rubbed with another stone shaped like a rolling-pin. A little water is thrown on it as it is bruised, and it is thus formed into paste. A ball of the paste is taken and flattened out between the hands into a cake about ten inches diameter and three-sixteenths of an inch thick, which is baked on a slightly concave earthenware pan. The cakes so made are called tortillas, and are very nutritious. When travelling, I preferred them myself to bread made from wheaten flour. When well made and eaten warm, they are very palatable.

There are a few small sugar plantations near Pital. The juice is pressed out of the canes by rude wooden rollers set upright in threes, the centre one driving the one on each side of it by projecting cogs. The whole are set in motion by oxen travelling round the same as in a thrashing-mill. The ungreased axles of the rollers, squeaking and screeching like a score of tormented pigs, generally inform the traveller of their vicinity long before he reaches them. The juice is boiled, and an impure sugar made from it. I do not think that the sugar-cane was known to the ancient inhabitants of the country: it is not mentioned by the historians of the conquest of Mexico and Peru, nor has it, like maize and cacao, any native name.

As soon as we passed Pital we entered the great forest, the black margin of which we had seen for many miles, that extends from this point to the Atlantic. At first the road lay through small trees and brushwood, a second growth that had sprung up where the original forest had been cut for maize plantations; but after passing a brook bordered by numerous plants of the pita, from which a fine fibre is obtained, and which gives its name to Pital, we entered the primeval forest. On each side of the road great trees towered up, carrying their crowns out of sight amongst a canopy of foliage; lianas wound round every trunk and hung from every bough, passing from tree to tree, and entangling the giants in a great network of coiling cables, as the serpents did Laocoon; the simile being strengthened by the fact that many of the trees are really strangled in the winding folds. Sometimes a tree appears covered with beautiful flowers, which do not belong to it, but to one of the lianas that twines through its branches and sends down great rope-like stems to the ground. Climbing ferns and vanilla cling to the trunks, and a thousand epiphytes perch themselves on the branches. Amongst these are large arums that send down aerial roots, tough and strong, and universally used instead of cordage by the natives. Amongst the undergrowth several small species of palms, varying in height from two to fifteen feet, are common; and now and then magnificent tree ferns, sending off their feathery crowns twenty feet from the ground, delight the sight with their graceful elegance. Great broad-leaved heliconiae, leathery melastomae, and succulent-stemmed, lop-sided-leaved begonias are abundant, and typical of tropical American forests. Not less so are the cecropia trees, with their white stems and large palmated leaves standing up like great candelabra. Sometimes the ground is carpeted with large flowers, yellow, pink, or white, that have fallen from some invisible tree-top above, or the air is filled with a delicious perfume, for the source of which one seeks around in vain, as the flowers that cause it are far overhead out of sight, lost in the great overshadowing crown of verdure. Numerous babbling brooks intersect the forest, with moss-covered stones and fern-clad nooks. One's thoughts are led away to the green dells in English denes, but are soon recalled; for the sparkling pools are the favourite haunts of the fairy humming-birds, and like an arrow one will dart up the brook, and, poised on wings moving with almost invisible velocity, clothed in purple, golden, or emerald glory, hang suspended in the air; gazing with startled look at the intruder, with a sudden jerk, turning round first one eye, then the other, and suddenly disappear like a flash of light.

Unlike the plains and savannahs we crossed yesterday, where the ground is parched up in the dry season, the Atlantic forest, bathed in the rains distilled from the north-east trades, is ever verdant. Perennial moisture reigns in the soil, perennial summer in the air, and vegetation luxuriates in ceaseless activity and verdure, all the year round. Unknown are the autumn tints, the bright browns and yellows of English woods, much less the crimsons, purples, and yellows of Canada, where the dying foliage rivals, nay, excels the expiring dolphin in splendour. Unknown the cold sleep of winter; unknown the lovely awakening of vegetation at the first gentle touch of spring. A ceaseless round of ever-active life weaves the forest scenery of the tropics into one monotonous whole, of which the component parts exhibit in detail untold variety and beauty.

To the genial influence of ever-present moisture and heat we must ascribe the infinite variety of the trees of these forests. They do not grow in clusters or masses of single species, like our oaks, beeches, and firs, but every tree is different from its neighbour, and they crowd upon each other in unsocial rivalry, each trying to overtop the other. For this reason we see the great straight trunks rising a hundred feet without a branch, and carrying their domes of foliage directly up to where the balmy breezes blow and the sun's rays quicken. Lianas hurry up to the light and sunshine, and innumerable epiphytes perch themselves high up on the branches.

The road through the forest was very bad, the mud deep and tenacious, the hills steep and slippery, and the mules had to struggle and plunge along through from two to three feet of sticky clay. One part, named the Nispral, was especially steep and difficult to descend, the road being worn into great ruts. We crossed the ranges and brooks nearly at right angles, and were always ascending or descending. About two we reached a clearing and hacienda, belonging to an enterprising German, named Melzer, near a brook called Las Lajas, who was cultivating plantains and vegetables, and had also commenced brick and tile making, besides planting some thousands of coffee trees. His large clearings were a pleasant change from the forest through which we had been toiling, and we stayed a few minutes at his house. After riding over another league of forest-covered ranges, we reached Pavon, one of the mines of the Chontales Company, and passing the Javali mine soon arrived at Santo Domingo, the headquarters of the gold-mining company whose operations I had come out to superintend.

The gold-mining village of Santo Domingo is situated in the province of Chontales, Nicaragua, in latitude 12 degrees 16 minutes north and longitude 84 degrees 59 minutes west, nearly midway between the Atlantic and the Pacific, where Central America begins to widen out northward of the narrow isthmus of Panama and Costa Rica. It is in the midst of the great forest that covers most of the Atlantic slope of Central America, and which continues unbroken from where we had entered it, at Pital, eastward to the Atlantic; westward it terminates in a sinuous margin about seven miles from the village, and there commence the lightly timbered and grassy plains and savannahs stretching to the Lake of Nicaragua. The surface of the land in the forest region forms a succession of ranges and steep valleys, covered with magnificent timber and much undergrowth. Santo Domingo lies about 2000 feet above the level of the sea, and the hills around it rise from 500 to 1000 feet higher. It is built in the bend of a small stream, the head waters of a branch of the Blewfields river, on a level, low piece of ground, with the brook winding almost round it, and, beyond that, encircled by an amphitheatre of low hills in the hollow of which it lies. The road to the mines runs through it, and forms the main street, having on each side thatched stores and irregularly built houses. The inhabitants, about three hundred in number, are entirely dependent on the mines around, there being no cultivation or any other employment in the immediate neighbourhood. The people are of a mixed descent, in which Indian blood predominates, then Spanish with a slight admixture of the Negro element, whilst amongst the rising generation many fair-haired children can claim paternity amongst the numerous German and English workmen that have been employed at the mines. The store-keepers form the aristocracy of the village. They are indolent; lounging about, or lying smoking in their hammocks the greater part of the day, but generally civil and polite. They are particular in their dress, and may often be seen in faultless European costume, silk umbrella in hand, in twos or threes, taking a short quiet walk up the valley. The lower class of miners are scantily and badly clothed, especially when they come first to the mines. They are bare-footed, with poor ragged cotton trousers and a thin jacket of the same material. Generally, after being a year or two at the mines, they begin to wear better clothing, and may often be seen with a new shirt, which to show off is worn hanging down outside, like a surtout coat. Amongst these are many pure Indians, short sturdy men, who make the steadiest workmen, patient and industrious, but with little appreciation of the value of money, and spending the whole of their wages at the end of the month, before they resume work. At these times the commandant comes in from the town of Libertad, about nine miles distant, with half-a-dozen bare-footed soldiers carrying old muskets on their shoulders, and levies blackmail upon the poor patient "Mosas," as they are called, in the shape of a fine for drunkenness. But the "aguardiente," a native-made rum, is nevertheless always kept on hand, being a government monopoly, and ever ready, so that the Mosas may have no excuse to be sober and escape being fined.

Even in their drink the poor Indians are not very violent, and get intoxicated with surprising stolidity and quietness. Amongst the half-breeds, especially where the Negro element exists, there are often quarrellings and rows, when they slash away at each other with their long knives or "machetes," and get ugly cuts, which, however, heal again quickly.

Both the Negroes and Indians are decidedly inferior to the whites in intellect, but they do not differ so much from the Europeans as they do from each other. The Negro will work hard for a short while, on rare occasions, or when compelled by another, but is innately lazy. The Indian is industrious by nature, and works steadily and well for himself; but if compelled to work for another, loses all heart, and pines away and dies. The Negro is talkative, vivacious, vain, and sensual; the Indian taciturn, stolid, dignified, and moderate. As freemen, regularly though poorly paid and kindly treated, the Indians work well and laboriously in the mines; but the Negro seldom engages either in that or any other settled employment, unless compelled as a slave, in which condition he is happy and thoughtless. I do not defend slavery, but I believe it to be a greater curse to the masters than to the slaves, more deteriorating to the former than to the latter. The Spaniards at first enslaved the Indians, but they died away so rapidly that in a very short time the indigenes of the whole of the once-populous islands of the West Indies were exterminated, and large numbers of Indians were carried off from the mainland to supply their places, but died with equal rapidity; so that the Spaniards found it more profitable to bring negroes from Africa, who thrived and multiplied in captivity as readily as the enslaved Indians pined away and died. In Central America there never were many black slaves; since the States threw off the yoke of Spain there have been none; and this comparative scarcity of the Negro element makes these countries much more pleasant and safer to dwell in than the West Indies, where it is much larger. The Indian seldom or never molests the whites, excepting in retaliation for some great injury; whilst amongst the free Negroes, robbery, violence, and murder need no other incentives than their own evil passions and lust.

The women at Santo Domingo are much the same as those found at all the small provincial towns of Central America. Morality is at a low ebb, and most of them live as mistresses, not as wives, for which they do not seem to suffer in the estimation of their neighbours. This is greatly due in Nicaragua, as it is throughout Central and South America, to the profligate lives led by the priests, who, with few rare exceptions, live in concubinage more or less open. The women have children at an early age, and make kind and indulgent mothers.

(PLATE 4. COMMISSIONER'S HOUSE AT SANTO DOMINGO.)

The village is bounded to the eastward by the mines and hacienda of the Chontales Mining Company, whose houses, workshops, and machinery are on rising ground on each side of the valley, with the brook running down between. About fifty acres of the forest have been cut down, and a great deal of this is fenced in and covered with grass. Going up the valley from the village, on the right hand side, about fifty yards from the road, on a grass-covered slope, stand the houses of the commissioner and cashier, in the latter of which the medical officer also lives. The former, a large, white-washed, square, two-storied, wooden house, with verandahs round three sides of it, and communicating by a covered passage with a detached kitchen behind, had been built by one of my predecessors, Captain Hill, R.N., who did not live to inhabit it. It was a roomy, comfortable house, commanding a view of the machinery, workshops, and part of the mines on the other side of the valley, and formed my residence for upwards of four years.

The slope in front of the house, down to the river, was covered with weedy bushes when I arrived; but I had these cleared away, and a fine greensward of grass took their place. On this I planted young orange, lime, and citron trees; and I had the pleasure, before I left, to see them beginning to bear their fine fruit. To the west of the house was a dell, covered with fallen logs and rubbish thrown from the hill, in which was a perennial spring of limpid water. I had the logs and rubbish gathered together and burnt, put a light fence round it, and formed a small vegetable, fruit, and flower garden. The mango and avocado trees had not come into bearing before I left; but pineapples, figs, grenadillas, bananas, pumpkins, plantains, papaws, and chioties fruited abundantly. The last named is a native of Mexico; it is a climbing plant with succulent stems and vine-like leaves, and grows with great rapidity. The fruit, of which it bears a great abundance, is about the size and shape of a pear, covered with soft prickles. It is boiled and eaten as a vegetable, and resembles vegetable marrow. At Santo Domingo it continues to bear a succession of fruits during eight months of the year.

Next to maize, plantains and bananas form the principal sustenance of the natives. The banana tree shoots up its succulent stem, and unfolds its immense entire leaves with great rapidity; and a group of them waving their silky leaves in the sun, or shining ghostly white in the moonlight, forms one of those beautiful sights that can only be seen to perfection in the tropics. There are a great many varieties of them, and they are cooked in many ways—boiled, baked, made into pastry, or eaten as a fruit. The varieties differ not only in their fruits, but in the colour of their leaves and stems; the natives can distinguish them without seeing the fruit, and have names for each, by which they are known throughout all Central America, Mexico, and Peru. These names are of Spanish origin; and this fact, together with the absence of any native, Mexican, or Peruvian name for the fruit, inclines me to adopt the opinion of Clavigero, who contends, in opposition to other writers, that the plantain and banana were not known in these countries before the Spanish conquest, but were first brought from the Canaries to Hayti in 1516, and from thence taken to the mainland.

Neither the sugar-cane* nor the plantain is given in the list of the indigenous productions of Mexico by the careful and accurate Hernandez. (* The sugar-cane is said never to bear seed in the West Indies, Malaga, India, Cochin China, or the Malay Archipelago. —Darwin's "Animals and Plants under Domestication" volume 2 page 169.) The natives made sugar from the green stems of the maize. Humboldt thinks that some species of plantain were indigenous to America; but it seems incredible that such an important fruit could have been overlooked by the early historians. In the old world the cultivation of the banana dates from the earliest times of which tradition makes mention. One of the Sanscrit names was bhanu—fruit, from which probably the name "banana" was derived.* (* Humboldt's "Aspects of Nature" volume 2 page 141.)

Both the plantain and the banana are always propagated from shoots or suckers that spring from the base of the plants; and it is to be remarked that the pineapple and the bread-fruit, that are also universally grown from cuttings or shoots, and have been cultivated from remote antiquity, have in a great measure lost the faculty of producing mature seed. Such varieties could not arise in a state of nature, but are due to selection by early races of mankind, who would naturally propagate the best varieties; and, to do this, seed was not required. As the finest kinds of bananas, pineapples, and bread-fruit are almost seedless, it is probable that the nutriment that would have been required for the formation of the seeds has been expended in producing larger and more succulent fruits. We find some varieties of oranges, which also have been cultivated from very early ages, producing fruits without seeds; but as these trees are propagated from seeds, these varieties could not become so sterile as those just mentioned. There can be no doubt that the seedless varieties of banana, bread-fruits, and pineapples have been propagated for hundreds of years; and this fact ought to modify the opinions generally entertained by horticulturists that the life of plants and trees propagated from shoots or cuttings cannot be indefinitely prolonged in that way. Perhaps this may be the case in trees, such as apples, that have come under their notice; and the reason that the varieties die out after a certain time, if not reproduced from seed, may be that the vigour of the trees is at last used up by the production of mature seed, but that in the seedless bananas, pineapples, and bread-fruits this does not happen.

Figs grow well in Nicaragua, and by many their luscious fruit is preferred to all others. My trees suffered greatly from the attacks of a large and fine longicorn beetle (Taeniotes scalaris, Fab.) which laid its eggs in the green bark, and produced white grubs that mined into the stem. I had to dig down to them with a knife to extricate them and prevent them destroying the young trees. We were surrounded at a short distance by the forest, in which grow many species of wild fig-trees; and this probably was the reason that my trees suffered so much, for at Granada the fig-growers were not troubled with this insect.

The grenadilla is the fruit of one of the passion-flowers (Passiflora quadrangularis), and is shaped like a large oblong apple, which it also resembles in perfume. It makes fine tarts and puddings, being somewhat like the gooseberry in taste. I had much difficulty in preserving it from being eaten by small forest rats that came out of the woods, where they had already been accustomed to eat the wild fruit of this climber.

The moist, warm climate seemed to suit the papaw tree, as it grew with great vigour, and produced very large and fine melon-like fruits. The green fruits are excellent for making pastry, if flavoured with a little lime-juice.

In vegetables, I grew three species of sweet potatoes—yellow, purple, and white skinned, and which differ also in their leaves and flowers; cabbages, kidney-beans, pumpkins, yuccas (Jatropha manihot), quequisque (a species of arum, Colocasia esculenta), lettuces, tomatoes, capiscums, endives, parsley, and carrots.

The climate was too damp to grow onions; neither could I succeed with peas, potatoes, or turnips. Scarlet runners (Phaseolus multiflorus) grew well, and flowered abundantly, but never produced a single pod. Darwin has shown that this flower is dependent, like many others, for its fertilisation upon the operations of the busy humble-bee, and that it is provided with a wonderful mechanism, by means of which its pollen is rubbed into the head of the bee, and received on the stigma of the next plant visited.* (* "Gardener's Chronicle" October 24, 1857 and November 14, 1858; also T.H. Farrer in "Annals of Natural History" October 1868.) There are many humble-bees, of different species from ours, in tropical America; but none of them frequented the flowers of the scarlet runner, and to that circumstance we may safely ascribe its sterility. An analogous case has been long known. The vanilla plant (Vanilla planifolia) has been introduced from tropical America into India, but though it grows well, and flowers, it never fruits without artificial aid. It is the same in the hothouses of Europe. Dr. Morren, of Liege, has shown that, if artificially fertilised, every flower will produce fruit; and ascribes its sterility to the absence, in Europe and India, of some insect that in America carries the pollen from one flower to another.* (* Taylor's "Annals of Natural History" volume 3 page 1.) When those interested in the acclimature of the natural productions of one country on the soil of some distant one, study the mutual relations of plants and animals, they will find that in the case of many plants it is important that the insects specially adapted for the fertilisation of their flowers should be introduced with them. Thus, if the insect or bird that assists in the fertilisation of the vanilla could be introduced into and would live in India, the growers of that plant would be relieved of much trouble, and it might be thoroughly naturalised. Judging from my experience, it would be useless to attempt the acclimature of the scarlet-runner bean in Chontales unless the humble-bee were also introduced.

Caterpillars, plant-lice, bugs, and insect pests of all kinds were numerous, and did much harm to my garden; but the greatest plague of all were the leaf-cutting ants, and I had to wage a continual warfare against them. During this contest I gained much information regarding their habits, and was successful in checking their ravages, and I shall occupy the remainder of this chapter with an account of them.

LEAF-CUTTING ANTS.

Nearly all travellers in tropical America have described the ravages of the leaf-cutting ants (Oecodoma); their crowded, well-worn paths through the forests, their ceaseless pertinacity in the spoliation of the trees—more particularly of introduced species—which are stripped bare and ragged with the midribs and a few jagged points of the leaves only left. Many a young plantation of orange, mango, and lemon trees has been destroyed by them. Again and again have I been told in Nicaragua, when inquiring why no fruit-trees were grown at particular places, "It is no use planting them; the ants eat them up." The first acquaintance a stranger generally makes with them is on encountering their paths on the outskirts of the forest crowded with the ants; one lot carrying off the pieces of leaves, each piece about the size of a sixpence, and held up vertically between the jaws of the ant; another lot hurrying along in an opposite direction empty-handed, but eager to get loaded with their leafy burdens. If he follows this last division, it will lead him to some young trees or shrubs, up which the ants mount; and then each one, stationing itself on the edge of a leaf, commences to make a circular cut, with its scissor-like jaws, from the edge, its hinder feet being the centre on which it turns. When the piece is nearly cut off, it is still stationed upon it, and it looks as though it would fall to the ground with it; but, on being finally detached, the ant is generally found to have hold of the leaf with one foot, and soon righting itself, and arranging its burden to its satisfaction, it sets off at once on its return. Following it again, it is seen to join a throng of others, each laden like itself, and, without a moment's delay, it hurries along the well-worn path. As it proceeds, other paths, each thronged with busy workers, come in from the sides, until the main road often gets to be seven or eight inches broad, and more thronged than the streets of the city of London.

After travelling for some hundreds of yards, often for more than half a mile, the formicarium is reached. It consists of low, wide mounds of brown, clayey-looking earth, above and immediately around which the bushes have been killed by their buds and leaves having been persistently bitten off as they attempted to grow after their first defoliation. Under high trees in the thick forest the ants do not make their nests, because, I believe, the ventilation of their underground galleries, about which they are very particular, would be interfered with, and perhaps to avoid the drip from the trees. It is on the outskirts of the forest, or around clearings, or near wide roads that let in the sun, that these formicariums are generally found. Numerous round tunnels, varying from half an inch to seven or eight inches in diameter, lead down through the mounds of earth; and many more from some distance around, also lead underneath them. At some of the holes on the mounds ants will be seen busily at work, bringing up little pellets of earth from below, and casting them down on the ever-increasing mound, so that its surface is nearly always fresh and new-looking.

Standing near the mounds, one sees from every point of the compass ant-paths leading to them, all thronged with the busy workers carrying their leafy burdens. As far as the eye can distinguish their tiny forms, troops upon troops of leaves are moving up towards the central point, and disappearing down the numerous tunnelled passages. The out-going, empty-handed hosts are partly concealed amongst the bulky burdens of the incomers, and can only be distinguished by looking closely amongst them. The ceaseless, toiling hosts impress one with their power, and one asks—What forests can stand before such invaders? How is it that vegetation is not eaten off the face of the earth? Surely nowhere but in the tropics, where the recuperative powers of nature are immense and ever active, could such devastation be withstood.

Further acquaintance with the subject will teach the inquirer that, just as many insects are preserved by being distasteful to insectivorous birds, so very many of the forest trees are protected from the ravages of the ants by their leaves either being distasteful to them, or unfitted for the purpose for which they are required, whilst some have special means of defence against their attacks. None of the indigenous trees appear so suitable for them as the introduced ones. Through long ages the trees and the ants of tropical America have been modified together. Varieties of plants that arose unsuitable for the ants have had an immense advantage over others that were more suitable; and thus through time every indigenous tree that has survived in the great struggle has done so because it has had originally, or has acquired, some protection against the great destroyer. The leaf-cutting ants are confined to tropical America; and we can easily understand that trees and vegetables introduced from foreign lands where these ants are unknown could not have acquired, excepting accidentally, and without any reference to the ants, any protection against their attacks, and now they are most eagerly sought by them. Amongst introduced trees, some species of even the same genus are more acceptable than others. Thus, in the orange tribe, the lime (Citrus lemonum) is less liked than the other species; it is the only one that I ever found growing really wild in Central America: and I have sometimes thought that even in the short time since the lime was first introduced, about three hundred years ago, a wild variety may have arisen, less subject to the attacks of the ants than the cultivated variety; for in many parts I saw them growing wild, and apparently not touched. The orange (Citrus aurantium) and the citron (Citrus medicus), on the other hand, are only found where they have been planted and protected by man; and, were he to give up their cultivation, the only species that would ultimately withstand the attacks of the ants, and obtain a permanent footing in Central America, would be the lime. The reason why the lime is not so subject to the attacks of the ants is unknown; and the fact that it is so is another instance of how little we know why one species of a particular genus should prevail over another nearly similar form. A little more or less acridity, or a slight chemical difference in the composition of the tissues of a leaf, so small that it is inappreciable to our senses, may be sufficient to ensure the preservation or the destruction of a species throughout an entire continent.

The ravages of this ant are so great that it may not be without interest for me to enter upon some details respecting the means I took to protect my own garden against their attacks, especially as the continual warfare I waged against them for more than four years made me acquainted with much of their wonderful economy.

In June 1869, very soon after the formation of my garden, the leaf-cutting ants came down upon it, and at once commenced denuding the young bananas, orange, and mango trees of their leaves. I followed up the paths of the invading hosts to their nest, which was about one hundred yards distant, close to the edge of the forest. The nest was not a very large one, the low mound of earth covering it being about four yards in diameter. At first I tried to stop the holes up, but fresh ones were immediately opened out: I then dug down below the mound, and laid bare the chambers beneath, filled with ant-food and young ants in every stage of growth; but I soon found that the underground ramifications extended so far, and to so great a depth, while the ants were continually at work making fresh excavations, that it would be an immense task to eradicate them by such means; and notwithstanding all the digging I had done the first day, I found them the next as busily at work as ever at my garden, which they were rapidly defoliating. At this stage, our medical officer, Dr. J.H. Simpson,* came to my assistance, and suggested pouring carbolic acid, mixed with water, down their burrows. (* This gentleman, beloved by all who knew him, of rare talent, and with every prospect of a prosperous career before him, died at Jamaica from hydrophobia, between two and three months after being bitten by a small dog that had not itself shown any symptoms of that disease.) The suggestion proved a most valuable one. We had a quantity of common brown carbolic acid, about a pint of which I mixed with four buckets of water, and, after stirring it well about, poured it down the burrows; I could hear it rumbling down to the lowest depths of the formicarium four or five feet from the surface. The effect was all I could have wished: the marauding parties were at once drawn off from my garden to meet the new danger at home. The whole formicarium was disorganised. Big fellows came stalking up from the cavernous regions below, only to descend again in the utmost perplexity.

Next day I found them busily employed bringing up the ant-food from the old burrows, and carrying it to a new one a few yards distant; and here I first noticed a wonderful instance of their reasoning powers. Between the old burrows and the new one was a steep slope. Instead of descending this with their burdens, they cast them down on the top of the slope, whence they rolled down to the bottom, where another relay of labourers picked them up and carried them to the new burrow. It was amusing to watch the ants hurrying out with bundles of food, dropping them over the slope, and rushing back immediately for more. They also brought out great numbers of dead ants that the fumes of the carbolic acid had killed. A few days afterwards, when I visited the locality again, I found both the old burrows and the new one entirely deserted, and I thought they had died off; but subsequent events convinced me that the survivors had only moved away to a greater distance.

It was fully twelve months before my garden was again invaded. I had then a number of rose-trees and also cabbages growing, which the ants seemed to prefer to everything else. The rose-trees were soon defoliated, and great havoc was made amongst the cabbages. I followed them to their nest, and found it about two hundred yards from the one of the year before. I poured down the burrows, as before, several buckets of water with carbolic acid. The water is required to carry the acid down to the lowest chambers. The ants, as before, were at once withdrawn from my garden; and two days afterwards, on visiting the place, I found all the survivors at work on one track that led directly to the old nest of the year before, where they were busily employed making fresh excavations. Many were bringing along pieces of the ant-food from the old to the new nests; others carried the undeveloped white pupae and larvae. It was a wholesale and entire migration; and the next day the formicarium down which I had last poured the carbolic acid was entirely deserted. I afterwards found that when much disturbed, and many of the ants destroyed, the survivors migrate to a new locality. I do not doubt that some of the leading minds in this formicarium recollected the nest of the year before, and directed the migration to it.

Don Francisco Velasquez informed me, in 1870, that he had a powder which made the ants mad, so that they bit and destroyed each other. He gave me a little of it, and it proved to be corrosive sublimate. I made several trials of it, and found it most efficacious in turning a large column of the ants. A little of it sprinkled across one of their paths in dry weather has a most surprising effect. As soon as one of the ants touches the white powder, it commences to run about wildly, and attack any other ant it comes across. In a couple of hours, round balls of the ants will be found all biting each other; and numerous individuals will be seen bitten completely in two, whilst others have lost some of their legs or antennae. News of the commotion is carried to the formicarium, and huge fellows, measuring three-quarters of an inch in length, that only come out of the nest during a migration or an attack on the nest or one of the working columns, are seen stalking down with a determined air, as if they would soon right matters. As soon, however, as they have touched the sublimate, all their stateliness leaves them: they rush about; their legs are seized hold of by some of the smaller ants already affected by the poison; and they themselves begin to bite, and in a short time become the centres of fresh balls of rabid ants. The sublimate can only be used effectively in dry weather. At Colon I found the Americans using coal tar, which they spread across their paths when any of them led to their gardens. I was also told that the Indians prevent them from ascending young trees by tying thick wisps of grass, with the sharp points downwards, round the stems. The ants cannot pass through the wisp, and do not find out how to surmount it, getting confused amongst the numberless blades, all leading downwards. I mention these different plans of meeting and frustrating the attacks of the ants at some length, as they are one of the greatest scourges of tropical America, and it has been too readily supposed that their attacks cannot be warded off. I myself was enabled, by using some of the means mentioned above, to cultivate successfully trees and vegetables of which the ants were extremely fond.

(PLATE 5. NEST OF LEAF-CUTTING ANT.)

Notwithstanding that these ants are so common throughout tropical America, and have excited the attention of nearly every traveller, there still remains much doubt as to the use to which the leaves are put. Some naturalists have supposed that they use them directly as food; others, that they roof their underground nests with them. I believe the real use they make of them is as a manure, on which grows a minute species of fungus, on which they feed;—that they are, in reality, mushroom growers and eaters. This explanation is so extraordinary and unexpected, that I may be permitted to enter somewhat at length on the facts that led me to adopt it. When I first began my warfare against the ants that attacked my garden, I dug down deeply into some of their nests. In our mining operations we also, on two occasions, carried our excavations from below up through very large formicariums, so that all their underground workings were exposed to observation. I found their nests below to consist of numerous rounded chambers, about as large as a man's head, connected together by tunnelled passages leading from one chamber to another. Notwithstanding that many columns of the ants were continually carrying in the cut leaves, I could never find any quantity of these in the burrows, and it was evident that they were used up in some way immediately they were brought in. The chambers were always about three parts filled with a speckled, brown, flocculent, spongy-looking mass of a light and loosely connected substance. Throughout these masses were numerous ants belonging to the smallest division of the workers, which do not engage in leaf-carrying. Along with them were pupae and larvae, not gathered together, but dispersed, apparently irregularly, throughout the flocculent mass. This mass, which I have called the ant-food, proved, on examination, to be composed of minutely subdivided pieces of leaves, withered to a brown colour, and overgrown and lightly connected together by a minute white fungus that ramified in every direction throughout it. I not only found this fungus in every chamber I opened, but also in the chambers of the nest of a distinct species that generally comes out only in the night-time, often entering houses and carrying off various farinaceous substances, and which does not make mounds above its nests, but long, winding passages, terminating in chambers similar to the common species, and always, like them, three parts filled with flocculent masses of fungus-covered vegetable matter, amongst which are the ant-nurses and immature ants. When a nest is disturbed, and the masses of ant-food spread about, the ants are in great concern to carry every morsel of it under shelter again; and sometimes, when I had dug into a nest, I found the next day all the earth thrown out filled with little pits that the ants had dug into it to get out the covered up food. When they migrate from one part to another, they also carry with them all the ant-food from their old habitations. That they do not eat the leaves themselves I convinced myself; for I found near the tenanted chambers, deserted ones filled with the refuse particles of leaves that had been exhausted as manure for the fungus, and were now left, and served as food for larvae of Staphylinidae and other beetles.* (*This theory that the leaf-cutting ants feed on a fungus which they cultivate has been confirmed by Mr. Fritz Muller, who had arrived at it independently in Brazil. His observations on this and various other habits of insects are contained in a letter to Mr. Charles Darwin, published in "Nature" of June 11, 1874.)

These ants do not confine themselves to leaves, but also carry off any vegetable substance that they find suitable for growing the fungus on. They are very partial to the inside white rind of oranges, and I have also seen them cutting up and carrying off the flowers of certain shrubs, the leaves of which they neglected. They are particular about the ventilation of their underground chambers, and have numerous holes leading up to the surface from them. These they open out or close up, apparently to keep up a regular degree of temperature below. The great care they take that the pieces of leaves they carry into the nest should be neither too dry nor too damp, is also consistent with the idea that the object is the growth of a fungus that requires particular conditions of temperature and moisture to ensure its vigorous growth. If a sudden shower should come on, the ants do not carry the wet pieces into the burrows, but throw them down near the entrances. Should the weather clear up again, these pieces are picked up when nearly dried, and taken inside; should the rain, however, continue, they get sodden down into the ground, and are left there. On the contrary, in dry and hot weather, when the leaves would get dried up before they could be conveyed to the nest, the ants, when in exposed situations, do not go out at all during the hot hours, but bring in their leafy burdens in the cool of the day and during the night. As soon as the pieces of leaves are carried in they must be cut up by the small class of workers into little pieces. I have never seen the smallest class of ants carrying in leaves; their duties appear to be inside, cutting them up into smaller fragments, and nursing the immature ants. I have, however, seen them running out along the paths with the others; but instead of helping to carry in the burdens, they climb on the top of the pieces which are being carried along by the middle-sized workers, and so get a ride home again. It is very probable that they take a run out merely for air and exercise. The largest class of what are called workers are, I believe, the directors and protectors of the others. They are never seen out of the nest, excepting on particular occasions, such as the migrations of the ants, and when one of the working columns or nests is attacked; they then come stalking up, and attack the enemy with their strong jaws. Sometimes, when digging into the burrows, one of these giants has unperceived climbed up my dress, and the first intimation of his presence has been the burying of his jaws in my neck, from which he would not fail to draw the blood. The stately observant way in which they stalk about, and their great size, compared with the others, always impressed me with the idea that in their bulky heads lay the brains that directed the community in its various duties. Many of their actions, such as that I have mentioned of two relays of workmen carrying out the ant-food, can scarcely be blind instinct. Some of the ants make mistakes, and carry in unsuitable leaves. Thus grass is nearly always rejected by them, yet I have seen some ants, perhaps young ones, carrying in leaves of grass. After a while these pieces were invariably brought out again and thrown away. I can imagine a young ant getting a severe earwigging from one of the major-domos for its stupidity.

I shall conclude this long account of the leaf-cutting ants with an instance of their reasoning powers. A nest was made near one of our tramways, and to get to the trees the ants had to cross the rails, over which the waggons were continually passing and repassing. Every time they came along a number of ants were crushed to death. They persevered in crossing for several days, but at last set to work and tunnelled underneath each rail. One day, when the waggons were not running, I stopped up the tunnels with stones; but although great numbers carrying leaves were thus cut off from the nest, they would not cross the rails, but set to work making fresh tunnels underneath them. Apparently an order had gone forth, or a general understanding been come to, that the rails were not to be crossed.

These ants do not appear to have many enemies, though I sometimes found holes burrowed into their nests, probably by the small armadillo. I once saw a minute parasitic fly hovering over a column of ants, near a nest, and every now and then darting down and attaching an egg to one entering. Large, horned beetles (Coelosis biloba) and a species of Staphylinus are found in the nests, but probably their larvae live on the rotten leaves, after the ants have done with them.

THERE is scarcely any level land around Santo Domingo, but in every direction a succession of hills and valleys. The hills are not isolated; they run in irregular ranges, having mostly an east and west direction, but with many modifications in their trend. From the main valleys numerous auxiliary ones cut deeply into the ranges, and bifurcate again and again, like the branches of a tree, forming channels for carrying off the great quantity of water that falls in these rainy forests. The branching valleys, all leading into main ones, and these into the rivers, have been excavated by subaerial agency, and almost entirely by the action of running water. It is the system that best effects the drainage of the country, and has been caused by that drainage.

The wearing out of valleys near Santo Domingo proceeds more rapidly than in regions where less rain falls, and where the rocks are not so soft and decomposed. Even during the few years I was in Nicaragua there were some modifications of the surface effected; I saw the commencement of new valleys, and the widening and lengthening of others, caused not only by the gradual denudation of the surface, but by landslips, some of which occur every wet season.

The rocks of the district are dolerytes, with bands and protrusions of hard greenstones. The decomposition of the dolerytes is very great, and extends from the tops of the hills to a depth (as proved in the mines), of at least two hundred feet. Next the surface they are often as soft as alluvial clay, and may be cut with a spade. This decomposition of the rocks near the surface prevails in many parts of tropical America, and is principally, if not always, confined to the forest regions. It has been ascribed, and probably with reason, to the percolation through the rocks of rain-water charged with a little acid from the decomposing vegetation. If this be so, the great depth to which it has reached tells of the immense antiquity of the forests.
