The willow, with its blood relation, the poplar, is often "pollarded," or trimmed for wood, and its abundant vigor enables it to recover from this process of violent abbreviation more satisfactorily than do most trees. The result is usually a disproportionately large stem or bole, for the lopping off of great branches always tends to a thickening of the main stem. The abundant leafage of both willow and poplar soon covers the scars, and there is less cause to mourn than in the case of maples or other "hard-wooded" trees.

If my readers will only add a willow section to their mental observation outfit, there will be much more to see and appreciate. Look for and enjoy in the winter the variation in twig color and bark hue; notice how smoothly lies the covering on one stem, all rugged and marked on another. In the earliest spring examine the swelling buds, of widely differing color and character, from which shortly will spring forth the catkins or aments of bloom, followed by the leaves of varied colors in the varied species, and with shapes as varied. Vivid green, soft gray, greenish yellow; dull surface and shining surface above, pale green to almost pure white beneath; from the long and stringy leaf of the weeping willow to the comparatively broad and thick leaf of the pussy-willow—there is variety and interest in the foliage well worth the attention of the tree-lover. When winter comes, there will be another set of contrasts to see in the way the various species lose their leaves and get ready for the rest time during which the buds mature and ripen, and the winter colors again shine forth.



These observations may be made anywhere in America, practically, for the willow is almost indifferent to locality, growing everywhere that its far-reaching roots can find the moisture which it loves, and which it rapidly transpires to the thirsty air. As Miss Keeler well remarks, "The genus Salix is admirably fitted to go forth and inhabit the earth, for it is tolerant of all soils and asks only water. It creeps nearer to the North Pole than any other woody plant except its companion the birch. It trails upon the ground or rises one hundred feet in the air. In North America it follows the water-courses to the limit of the temperate zone, enters the tropics, crosses the equator, and appears in the mountains of Peru and Chili.... The books record one hundred and sixty species in the world, and these sport and hybridize to their own content and to the despair of botanists. Then, too, it comes of an ancient line; for impressions of leaves in the cretaceous rocks show that it is one of the oldest of plants."

Common it is, and therefore overlooked; but the reader may well resolve to watch the willow in spring and summer, with its bloom and fruit; to follow its refreshing color through winter's chill; to observe its cheer and dignity; and to see the wind toss its slender wands and turn its graceful leaves.

The poplars and the willows are properly considered together, for together they form the botanical world family of the Salicaceae. Many characteristics of bloom and growth, of sap and bark, unite the two, and surely both, though alike common to the world, are common and familiar trees to the dwellers in North America.



One of my earliest tree remembrances has to do with a spreading light-leaved growth passed under every day on the way to school—and, like most school-boys, I was not unwilling to stop for anything of interest that might put off arrival at the seat of learning. This great tree had large and peculiar winter buds, that always seemed to have advance information as to the coming of spring, for they would swell out and become exceedingly shiny at the first touch of warm sun. Soon the sun-caressing would be responded to by the bursting of the buds, or the falling away of their ingenious outer protecting scales, which dropped to the ground, where, sticky and shining, and extraordinarily aromatic in odor, they were just what a curious school-boy enjoyed investigating. "Balm of Gilead" was the name that inquiry brought for this tree, and the resinous and sweet-smelling buds which preceded the rather inconspicuous catkins or aments of bloom seemed to justify the Biblical designation.

Nearly a world tree is this poplar, which in some one of its variable forms is called also tacamahac, and balsam poplar as well. Its cheerful upright habit, really fine leaves and generally pleasing air commend it, but there is one trouble—it is almost too vigorous and anxious to spread, which it does by means of shoots or "suckers," upspringing from its wide area of root-growth, thus starting a little forest of its own that gives other trees but small chance. But on a street, where the repression of pavements and sidewalks interferes with this exuberance, the balsam poplar is well worth planting.

The poplars as a family are pushing and energetic growers, and serve a great purpose in the reforestation of American acres that have been carelessly denuded of their tree cover. Here the trembling aspen particularly, as the commonest form of all is named, comes in to quickly cover and shade the ground, and give aid to the hard woods and the conifers that form the value of the forest growth.

This same American aspen, a consideration of the lightly hung leaves of which has been useful to many poets, is a well-known tree of graceful habit, particularly abundant in the forests north of Pennsylvania and New Jersey, and occupying clearings plentifully and quickly. Its flowers are in catkins, as with the rest of the family, and, like other poplars, they are in two kinds, male and female, or staminate and pistillate, which accounts for some troubles the inexperienced investigator has in locating them.

There is another aspen, the large-toothed form, that is a distinct botanical species; but I have never been able to separate it, wherefore I do not try to tell of it here, lest I fall under condemnation as a blind leader, not of the blind, but of those who would see!

In many cities, especially in cities that have experienced real-estate booms, and have had "extensions" laid out "complete with all improvements," there is to be seen a poplar that has the merit of quick and pleasing growth and considerable elegance as well. Alas, it is like the children of the tropics in quick beauty and quick decadence! The Carolina poplar, it is called, being a variety of the wide-spread cottonwood. Grow? All that is needed is to cut a lusty branch of it, point it, and drive it into the earth—it will do the rest!

This means cheap trees and quick growth, and that is why whole new streets in West Philadelphia, for instance, are given up to the Carolina poplar. Its clear, green, shining leaves, of good size, coming early in spring; its easily guided habit, either upright or spreading; its very rapid growth, all commend it. But its coarseness and lack of real strength, and its continual invitation to the tree-butcher and the electric lineman, indicate the undesirability of giving it more than a temporary position, to shade while better trees are growing.



But I must not get into the economics of street-tree planting. I started to tell of the blossoms of this same Carolina poplar, which are decidedly interesting. Just when the sun has thoroughly warmed up the air of spring there is a sudden, rapid thickening of buds over one's head on this poplar. One year the tree under my observation swelled and swelled its buds, which were shining more and more in the sun, until I was sure the next day would bring a burst of leaves. But the weather was dry, and it was not until that wonderful solvent and accelerator of growing things, a warm spring rain, fell softly upon the tree, that the pent-up life force was given vent. Then came, not leaves, but these long catkins, springing out with great rapidity, until in a few hours the tree glowed with their redness. A second edition of the shower, falling sharply, brought many of the catkins to the ground, where they lay about like large caterpillars.

The whole process of this blooming was interesting, curious, but hardly beautiful, and it seemed to fit in with the restless character of the poplar family—a family of trees with more vigor than dignity, more sprightliness than grace. As Professor Bailey says of the cottonwood, "It is cheerful and restive. One is not moved to lie under it as he is under a maple or an oak." Yet there are not wanting some poplars of impressive character.

One occurs to me, growing on a wide street of my home town, opposite a church with a graceful spire. This white or silver-leaved poplar has for many years been a regular prey of the gang of tree-trimmers, utterly without knowledge of or regard for trees, that infests this town. They hack it shamefully, and I look at it and say, "Well, the old poplar is ruined now, surely!" But a season passes, and I look again, to see that the tremendous vigor of the tree has triumphed over the butchers; its sores have been concealed, new limbs have pushed out, and it has again, in its unusual height, assumed a dignity not a whit inferior to that of the church spire opposite.



This white poplar is at its best on the bank of a stream, where its small forest of "suckers" most efficiently protects the slope against the destructive action of floods. One such tree with its family and friends I saw in full bloom along the Susquehanna, and it gave an impression of solidity and size, as well as of lusty vigor, and I have always liked it since. The cheerful bark is not the least of its attractions—but it is a tree for its own place, and not for every place, by reason of the tremendous colonizing power of its root-sprouts.

I wonder, by the way, if many realize the persistence and vigor of the roots of a tree of the "suckering" habit? Some years ago an ailanthus, a tree of vigor and beauty of foliage but nastiness of flower odor, was cut away from its home when excavation was being made for a building, which gave me opportunity to follow a few of its roots. One of them traveled in search of food, and toward the opportunity of sending up a shoot, over a hundred feet!

The impending scarcity of spruce logs to feed the hungry maws of the machines that make paper for our daily journals has turned attention to several forms of the rapid-growing poplar for this use. The aspen is acceptable, and also the Carolina poplar, and these trees are being planted in large quantities for the eventual making of wood-pulp. Even today, many newspapers are printed on poplar, and exposure to the rays of the truth-searching sun for a few hours will disclose the yellowness of the paper, if not of the tree from which it has been ground.



Few whose eyes are turned upward toward the trees have failed to note that exclamation-point of growth, the Lombardy poplar. Originating in that portion of Europe indicated by its common name, and, indeed, a botanical form of the European black poplar, it is nevertheless widely distributed in America. When it has been properly placed, it introduces truly a note of distinction into the landscape. Towering high in the air, and carrying the eye along its narrowly oval contour to a skyward point, it is lofty and pleasing in a park. It agreeably breaks the sky-line in many places, and is emphatic in dignified groups. To plant it in rows is wrong; and I say this as an innocent offender myself. In boyhood I lived along the banks of the broad but shallow Susquehanna, and enjoyed the boating possible upon that stream when it was not reduced, as graphically described by a disgusted riverman, to merely a heavy dew. Many times I lost my way returning to the steep bluff near my home after the sun had gone to rest, and a hard pull against the swift current would ensue as I skirted the bank, straining eyes for landmarks in the dusk. It occurred to me to plant six Lombardy poplars on the top of the bluff, which might serve as easily recognized landmarks. Four of them grew, and are now large trees, somewhat offensive to a quickened sense of appropriateness. Long since the old home has been swallowed up by the city's advance, and I suppose none who now see those four spires of green on the river-bank even guess at the reason for their existence.

The poplar family, as a whole, is exuberant with vigor, and interesting more on that account than by reason of its general dignity or strength or elegance. It is well worth a little attention and study, and the consideration particularly of its bloom periods, to which I commend the tree-sense of my readers as they take the tree walks that ought to punctuate these chapters.



The Elm and the Tulip

America has much that is unique in plant and tree growth, as one learns who sees first the collections of American plants shown with pride by acute gardeners and estate owners in England and on the European Continent. Many a citizen of our country must needs confess with some shame that his first estimation of the singular beauty of the American laurel has been born in England, where the imported plants are carefully nurtured; and the European to whom the rhododendrons of his own country and of the Himalayas are familiar is ready to exclaim in rapture at the superb effect and tropical richness of our American species, far more lusty and more truly beautiful here than the introductions which must be heavily paid for and constantly coddled.

For no trees, however, may Americans feel more pride than for our American elms and our no less American tulip, the latter miscalled tulip "poplar." Both are trees practically unique to the country, both are widespread over Eastern North America, both are thoroughly trees of the people, both attain majestic proportions, both are long-lived and able to endure much hardship without a full giving up of either beauty or dignity.

The American elm—how shall I properly speak of its exceeding grace and beauty! In any landscape it introduces an element of distinction and elegance not given by any other tree. Looking across a field at a cluster of trees, there may be a doubt as to the identity of an oak, a chestnut, a maple, an ash, but no mistake can be made in regard to an elm—it stands alone in the simple elegance of its vase-like form, while its feathery branchlets, waving in the lightest breeze, add to the refined and classic effect. I use the word "classic" advisedly, because, although apparently out of place in describing a tree, it nevertheless seems needed for the form of the American elm.

The elm is never rugged as is the oak, but it gives no impression of effeminacy or weakness. Its uprightness is forceful and strong, and its clean and shapely bole impresses the beholder as a joining of gently outcurving columns, ample in strength and of an elegance belonging to itself alone. If I may dare to compare man-made architectural forms with the trees that graced the garden of Eden, I would liken the American elm (it is also the water elm and the white elm, and botanically Ulmus Americana) to the Grecian types, combining stability with elegance, rather than to the more rugged works of the Goths. Yet the free swing of the elm's wide-spreading branches inevitably suggests the pointed Gothic arch in simplicity and obvious strength.

It is difficult to say when the American elm is most worthy of admiration. In summer those same arching branches are clothed and tipped with foliage of such elegance and delicacy as the form of the tree would seem to predicate. The leaf itself is ornate, its straight ribs making up a serrated and pointed oval form of the most interesting character. These leaves hang by slender stems, inviting the gentlest zephyr to start them to singing of comfort in days of summer heat. The elm is fully clothed down to the drooping tips of the branchlets with foliage, which, though deepest green above, reflects, under its dense shade, a soft light from the paler green of the lower side. It is no wonder that New England claims fame for her elms, which, loved and cared for, arch over the long village streets that give character to the homes of the descendants of the Puritan fathers. The fully grown elm presents to the sun a darkly absorbent hue, and to the passer-by who rests beneath its shade the most grateful and restful color in all the rainbow's palette.



Then, too, the evaporative power of these same leaves is simply enormous, and generally undreamed of. Who would think that a great, spreading elm, reaching into the air of August a hundred feet, and shading a circle of nearly as great diameter, was daily cooling the atmosphere with tons of water, silently drawn from the bosom of Mother Earth!

Like many other common trees, the American elm blooms almost unnoticed. When the silver maple bravely pushes out its hardy buds in earliest spring—or often in what might be called latest winter—the elm is ready, and the sudden swelling of the twigs, away above our heads in March or April, is not caused by the springing leaves, but is the flowering effort of this noble tree. The bloom sets curiously about the yet bare branches, and the little brownish yellow or reddish flowers are seemingly only a bunch of stamens. They do their work promptly, and the little flat fruits, or "samaras," are ripened and dropped before most of us realize that the spring is fully upon us. These seeds germinate readily, and I recall the great pleasure with which a noted horticultural professor showed me what he called his "elm lawn," one summer. It seemed that almost every one of the thousands of seeds that, just about the time his preparations for sowing a lawn were completed, had softly fallen from the great elm which guards and shades his dooryard, had found good ground, and the result was a miniature forest of tiny trees, giving an effect of solid green which was truly a tree lawn.



But, after all, I think it is in winter that the American elm is at its finest, for then stand forth most fully revealed the wonderful symmetry of its structure and the elegance of its lines. It has one advantage in its great size, which is well above the average, for it lifts its graceful head a hundred feet or more above the earth. The stem is usually clean and regular, and the branches spread out in closely symmetrical relation, so that, as seen against the cold sky of winter, leafless and bare, they seem all related parts of a most harmonious whole. Other great trees are notable for the general effect of strength or massiveness, individual branches departing much from the average line of the whole structure; but the American elm is regular in all its parts, as well as of general stateliness.

As I have noted, the people of the New England States value and cherish their great elms, and they are accustomed to think themselves the only possessors of this unique tree. We have, however, as good elms in Pennsylvania as there are in New England, and I hope the day is not far distant when we shall esteem them as highly. The old elm monarch which stands at the gingerbread brownstone entrance of the Capitol Park in Pennsylvania's seat of government has had a hard battle, defenseless as it is, against the indifference of those whom it has shaded for generations, and who carelessly permitted the telegraph and telephone linemen to use it or chop it at their will. But latterly there has been an awakening which means protection, I think, for this fine old landmark.

The two superb elms, known as "Paul and Virginia," that make notable the north shore of the Susquehanna at Wilkesbarre, are subjects of local pride; which seems, however, not strong enough to prevent the erection of a couple of nasty little shanties against their great trunks. There can be no doubt, however, that the sentiment of reverence for great trees, and of justice to them for their beneficent influence, is spreading westward and southward from New England. It gives me keen pleasure to learn of instances where paths, pavements or roadways have been changed, to avoid doing violence to good trees; and a recent account of the creation of a trust fund for the care of a great oak, as well as a unique instance in Georgia, where a deed has been recorded giving a fine elm a quasi-legal title to its own ground, show that the rights of trees are coming to be recognized.

I have said little of the habitat, as the botanist puts it, of the American elm. It graces all North America east of the Rockies, and the specimens one sees in Michigan or Canada are as happy, apparently, as if they grew in Connecticut or in Virginia. Our increasingly beautiful national Capital, the one city with an intelligent and controlled system of tree-planting, shows magnificent avenues of flourishing elms.

But I must not forget some other elms, beautiful and satisfactory in many places. It is no discredit to our own American elm to say that the English elm is a superb tree in America. It seems to be characteristically British in its sturdy habit, and forms a grand trunk.



The juicy inner bark of the red or "slippery" elm was always acceptable, in lieu of the chewing-gum which had not then become so common, to a certain ever-hungry boy who used to think as much of what a tree would furnish that was eatable as he now does of its beauty. Later, the other uses of the bark of this tree became known to the same boy, but it was many years before he came really to know the slippery elm. One day a tree branch overhead showed what seemed to be remarkable little green flowers, which on examination proved to be, instead, the very interesting fruit of this elm, each little seed securely held inside a very neat and small flat bag. Looking at it earlier the next spring, the conspicuous reddish brown color of the bud-scales was noted.

I have never seen the "wahoo," or winged elm of the South, and there are several other native elms, as well as a number of introductions from the Eastern Hemisphere, with which acquaintance is yet to be made. All of them together, I will maintain with the quixotic enthusiasm of lack of knowledge, are not worth as much as one-half hour spent in looking up under the leafy canopy of our own preeminent American elm—a tree surely among those given by the Creator for the healing of the nations.

The tulip-tree, so called obviously because of the shape of its flowers, has a most mellifluous and pleasing botanical name, Liriodendron Tulipifera—is not that euphonious? Just plain "liriodendron"—how much better that sounds as a designation for one of the noblest of American forest trees than the misleading "common" names! "Tulip-tree," for a resemblance of the form only of its extraordinary blooms; "yellow poplar," probably because it is not yellow, and is in no way related to the poplars; and "whitewood," the Western name, because its wood is whiter than that of some other native trees. "Liriodendron" translated means "lily-tree," says my learned friend who knows Greek, and that is a fitting designation for this tree, which proudly holds forth its flowers, as notable and beautiful as any lily, and far more dignified and refined than the gaudy tulip. I like to repeat this smooth-sounding, truly descriptive and dignified name for a tree worthy all admiration. Liriodendron! Away with the "common" names, when there is such a pleasing scientific cognomen available!

By the way, why should people who will twist their American tongues all awry in an attempt to pronounce French words in which the necessary snort is unexpressed visually and half the characters are "silent," mostly exclaim at the alleged difficulty of calling trees and plants by their world names, current among educated people everywhere, while preferring some misleading "common" name? Very few scientific plant names are as difficult to pronounce as is the word "chrysanthemum," and yet the latter comes as glibly from the tongue as do "geranium," "rhododendron," and the like. Let us, then, at least when we have as good a name as liriodendron for so good a tree, use it in preference to the most decidedly "common" names that belie and mislead.

I have said that this same tulip-tree—which I will call liriodendron hereafter, at a venture—is a notable American tree, peculiar to this country. So believed the botanists for many years, until an inquiring investigator found that China, too, had the same tree, in a limited way. We will still claim it as an American native, and tell the Chinamen they are fortunate to have such a superb tree in their little-known forests. They have undoubtedly taken advantage, in their art forms, of its peculiarly shaped leaves, if not of the flowers and the curious "candlesticks" that succeed them.



Let us consider this liriodendron first as a forest tree, as an inhabitant of the "great woods" that awed the first intelligent observers from Europe, many generations back. Few of our native trees reach such a majestic height, here on the eastern side of the continent, its habitat. Ordinarily it builds its harmonious structure to a height of seventy or a hundred feet; but occasional individuals double this altitude, and reach a trunk diameter of ten feet. While in the close forest it towers up with a smooth, clean bole, in open places it assumes its naturally somewhat conical form very promptly. Utterly dissimilar in form from the American elm, it seems to stand for dignity, solidity and vigor, and yet to yield nothing in the way of true elegance. The botanists tell us it prefers deep and moist soil, but I know that it lives and seems happy in many soils and in many places. Always and everywhere it shows a clean, distinct trunk, its brown bark uniformly furrowed, but in such a manner as to give a nearly smooth appearance at a little distance. The branches do not leave the stem so imperceptibly as do those which give the elm its very distinct form, but rather start at a right angle, leaving the distinct central column of solid strength unimpaired. The winter tracery of these branches, and the whole effect of the liriodendron without foliage, is extremely distinct and pleasing. I have in mind a noble group of great liriodendrons which I first saw against an early April sky of blue and white. The trees had grown close, and had interlaced their somewhat twisty branches, so that the general impression was that of one great tree supported on several stems. The pure beauty of these very tall and very stately trees, thus grouped and with every twig sharply outlined, I shall always remember.

The liriodendron is more fortunate than some other trees, for it has several points of attractiveness. Its stature and its structure are alike notable, its foliage entirely unique, and its flowers and seed-pods even more interesting. The leaf is very easily recognized when once known. It is large, but not in any way coarse, and is thrust forth as the tree grows, in a peculiarly pleasing way. Sheathed in the manner characteristic of the magnolia family, of which the liriodendron is a notable member, the leaves come to the light practically folded back on themselves, between the two protecting envelopes, which remain until the leaf has stretched out smoothly. Yellowish green at first, they rapidly take on the bright, strong green of maturity. The texture is singularly refined, and it is a pleasure to handle these smooth leaves, of a shape which stamps them at once on the memory, and of a coloring, both above and below, that is most attractive. They are maintained on long, slender stems, or "petioles," and these stems give a great range of flexibility, so that the leaves of the liriodendron are, as Henry Ward Beecher puts it, "intensely individual, each one moving to suit himself."



Of course all this moving, and this out-breaking of the leaves from their envelopes, take place far above one's head, on mature trees. It will be found well worth while, however, for the tree-lover to look in the woods for the rather numerous young trees of the tulip, and to observe the very interesting way in which the growth proceeds. The beautiful form and color of the leaves may also be thus conveniently noted, as also in the autumn the soft, clear yellow early assumed.

It is the height and spread of the liriodendron that keep its truly wonderful flowers out of the public eye. If they were produced on a small tree like the familiar dogwood, for instance, so that they might be nearer to the ground, they would receive more of the admiration so fully their due. In Washington, where, as I have said, trees are planted by design and not at random, there are whole avenues of liriodendrons, and it was my good fortune one May to drive between these lines of strong and shapely young trees just when they were in full bloom. The appearance of these beautiful cups, each one held upright, not drooping, was most striking and elegant. Some time, other municipalities will learn wisdom from the example set in Washington, and we may expect to see some variety in our street trees, now monotonously confined for the most part to the maples, poplars, and a few good trees that would be more valued if interspersed with other equally good trees of different character. The pin-oak, the elm, the sweet-gum, or liquidambar, the ginkgo, and a half-dozen or more beautiful and sturdy trees, do admirably for street planting, and ought to be better known and much more freely used.



I have seen many rare orchids brought thousands of miles and petted into a curious bloom—indeed, often more curious than beautiful. If the bloom of the liriodendron, in all its delicate and daring mingling of green and yellow, cream and orange, with its exquisite interior filaments, could be labeled as a ten-thousand-dollar orchid beauty from Borneo, its delicious perfume would hardly be needed to complete the raptures with which it would be received into fashionable flower society. But these lovely cups stand every spring above our heads by millions, their fragrance and form, their color and beauty, unnoticed by the throng. As they mature into the brown fruit-cones that hold the seeds, and these in turn fall to the ground, to fulfil their purpose of reproduction, there is no week in which the tree is not worthy of attention; and, when the last golden leaf has been plucked by the fingers of the winter's frost, there yet remain on the bare branches the curious and interesting candlestick-like outer envelopes of the fruit-cones, to remind us in form of the wonderful flower, unique in its color and attractiveness, that gave its sweetness to the air of May and June.

These two trees—the elm and the liriodendron—stand out strongly as individuals in the wealth of our American trees. Let all who read and agree in my estimate, even in part, also agree to try, when opportunity offers, to preserve these trees from vandalism or neglect, realizing that the great forest trees of our country are impossible of replacement, and that their strength, majesty and beauty are for the good of all.



Nut-Bearing Trees

What memories of chestnutting parties, of fingers stained with the dye of walnut hulls, and of joyous tramps afield in the very heart of the year, come to many of us when we think of the nuts of familiar knowledge! Hickory-nuts and butternuts, too, perhaps hazelnuts and even beechnuts—all these American boys and girls of the real country know. In the far South, and, indeed, reaching well up into the Middle West, the pecan holds sway, and a majestic sway at that, for its size makes it the fellow of the great trees of the forest, worthy to be compared with the chestnut, the walnut, and the hickory.

But it has usually been of nuts to eat that we have thought, and the chance for palatable food has, just as with some of the best of the so-called "fruit" trees—all trees bear fruit!—partially closed our eyes to the interest and beauty of some of these nut-bearers.

My own tree acquaintance has proceeded none too rapidly, and I have been—and am yet—as fond of the toothsome nuts as any one can be who is not a devotee of the new fad that attempts to make human squirrels of us all by a nearly exclusive nut diet. I think that my regard for a nut tree as something else than a source of things to eat began when I came, one hot summer day, under the shade of the great walnut at Paxtang. Huge was its trunk and wide the spread of its branches, while the richness of its foliage held at bay the strongest rays of the great luminary. How could I help admiring the venerable yet lusty old tree, conferring a present benefit, giving an instant and restful impression of strength, solidity, and elegance, while promising as well, as its rounded green clusters hung far above my head, a great crop of delicious nut-fruit when the summer's sun it was so fully absorbing should have done its perfect work!

Alas for the great black walnut of Paxtang! It went the way of many another tree monarch whose beauty and living usefulness were no defense against sordid vandalism. In the course of time a suburb was laid out, including along its principal street, and certainly as its principal natural ornament, this massive tree, around which the Indians who roamed the "great vale of Pennsylvania" had probably gathered in council. The sixty-foot "lot," the front of which the tree graced, fell to the ownership of a man who, erecting a house under its beneficent protection, soon complained of its shade. Then came a lumber prospector, who saw only furniture in the still flourishing old black walnut. His offer of forty dollars for the tree was eagerly accepted by the Philistine who had the title to the land, and although there were not wanting such remonstrances as almost came to a breaking of the peace, the grand walnut ended its hundreds of years of life to become mere lumber for its destroyers! The real estate man who sold the land greatly admired the tree himself, realizing also its great value to the suburb, and had never for one moment dreamed that the potential vandal who bought the tree-graced parcel of ground would not respect the inherent rights of all his neighbors. He told me of the loss with tears in his eyes and rage in his language; and I have never looked since at the fellow who did the deed without reprobation. More than that, he has proven a theory I hold—that no really good man would do such a thing after he had been shown the wrong of it—by showing himself as dishonest in business as he was disregardful of the rights of the tree and of his neighbors.



The black walnut is a grand tree from any point of view, even though it so fully absorbs all water and fertility as to check other growth under its great reach of branches. The lines it presents to the winter sky are as rugged as those of the oak, but there is a great difference. And this ruggedness is held far into the spring, for the black walnut makes no slightest apparent effort at growth until all the other trees are greening the countryside. Then with a rush come the luxuriant and tropical compound leaves, soon attaining their full dignity, and adding to it also a smooth polish on the upper surface. The walnut's flowers I have missed seeing, I am sorry to say, while registering a mental promise not to permit another season to pass without having that pleasure.

Late in the year the foliage has become scanty, and the nut-clusters hang fascinatingly clear, far above one's head, to tempt the climb and the club. The black walnut is a tree that needs our care; for furniture fashion long used its close-grained, heavy, handsome wood as cruelly as the milliners did the herons of Florida from which were torn the "aigrets," now happily "out of style." Though walnut furniture is no longer the most popular, the deadly work has been done, for the most part, and but few of these wide-spread old forest monarchs yet remain. Scientific forestry is now providing, in many plantings, and in many places, another "crop" of walnut timber, grown to order, and using waste land. It is to such really beneficent, though entirely commercial work, that we must look for the future of many of our best trees.

The butternut, or white walnut, has never seemed so interesting to me, nor its fruit so palatable, probably because I have seen less of it. The so-called "English" walnut, which is really the Persian walnut, is not hardy in the eastern part of the United States, and, while a tree of vast commercial importance in the far West, does not come much into the view of a lover of the purely American trees.



Of the American sweet chestnut as a delightful nut-fruit I need say nothing more than that it fully holds its place against "foreign intervention" from the East; even though these European and Japanese chestnuts with their California-bred progeny give us fruit that is much larger, and borne on trees of very graceful habit. No one with discrimination will for a moment hesitate, after eating a nut of both, to cheerfully choose the American native as best worth his commendation, though he may come to understand the food value, after cooking, of the chestnuts used so freely in parts of Europe.



As a forest tree, however, our American sweet chestnut has a place of its own. Naturally spreading in habit when growing where there is room to expand, it easily accommodates itself to the more cramped conditions of our great woodlands, and shoots upward to light and air, making rapidly a clean and sturdy stem. What a beautiful and stately tree it is! And when, late in the spring, or indeed right on the threshold of summer, its blooming time comes, it stands out distinctly, having then few rivals in the eye of the tree-lover. The locust and the tulip are just about done with their floral offering upon the altar of the year when the long creamy catkins of the sweet chestnut spring out from the fully perfected dark green leaf-clusters. Peculiarly graceful are these great bloom heads, high in the air, and standing nearly erect, instead of hanging down as do the catkins of the poplars and the birches. The odor of the chestnut flower is heavy, and is best appreciated far above in the great tree, where it may mingle with the warm air of June, already bearing a hundred sweet scents.

There stands bright in my remembrance one golden June day when I came through a gateway into a wonderful American garden of purely native plants maintained near Philadelphia, the rock-bound drive guarded by two clumps of tall chestnuts, one on either side, and both in full glory of bloom. There could not have been a more beautiful, natural, or dignified entrance; and it was just as beautiful in the early fall, when the deep green of the oblong-toothed leaves had changed to clear and glowing yellow, while the flowers had left their perfect work in the swelling and prickly green burs which hid nuts of a brown as rich as the flesh was sweet.

Did you, gentle reader, ever saunter through a chestnut grove in the later fall, when the yellow had been browned by the frosts which brought to the ground alike leaves and remaining burs? There is something especially pleasant in the warmth of color and the crackle of sound on the forest floor, as one really shuffles through chestnut leaves in the bracing November air, stooping now and then for a nut perchance remaining in the warm and velvety corner of an opened bur.

Here in Pennsylvania, and south of Mason and Dixon's line, there grows a delightful small tree, brother to the chestnut, bearing especially sweet little nuts which we know as chinquapins. They are darker brown, and the flesh is very white, and rich in flavor. I could wish that the chinquapin, as well as the chestnut, was included among the trees that enlightened Americans would plant along roadsides and lanes, with other fruit trees; the specific secondary purpose, after the primary enjoyment of form, foliage and flower, being to let the future passer-by eat freely of that fruit provided by the Creator for food and pleasure, and costing no more trouble or expense than the purely ornamental trees more frequently planted.

Both chestnut and chinquapin are beautiful ornamental trees; and some of the newer chestnut hybrids, of parentage between the American and the European species, are as graceful as the most highly petted lawn trees of the nurserymen. Indeed, the very same claim may be made for a score or more of the standard fruit trees, alike beautiful in limb tracery, in bloom, and in the seed-coverings that we are glad to eat; and some time we shall be ashamed not to plant the fruit trees in public places, for the pleasure and the refreshing of all who care.



One of the commonest nut trees, and certainly one of the most pleasing, is the hickory. There are hickories and hickories, and some are shellbarks, while others are bitternuts or pignuts. The form most familiar to the Eastern States is the shagbark hickory, and its characteristic upright trees, tall and finely shaped, never wide-spreading as is the chestnut under the encouragement of plenty of room and food, are admirable from any standpoint. There is a lusty old shagbark in Wetzel's Swamp that has given me many a pleasant quarter-hour, as I have stood at attention before its symmetrical stem, hung with slabs of brown bark that seem always just ready to separate from the trunk.

The aspect of this tree is reflected in its very useful timber, which is pliant but tough, requiring less "heft" for a given strength, and bending with a load easily, only to instantly snap back to its position when the stress slackens. Good hickory is said to be stronger than wrought iron, weight for weight; and I will answer for it that no structure of iron can ever have half the grace, as well as strength, freely displayed by this same old shagbark of the lowlands near my home.

Curious as I am to see the blooms of the trees I am getting acquainted with, there are many disappointments to be endured—as when the favorite tree under study is reached a day too late, and I must wait a year for another opportunity. It was, therefore, with much joy that I found that a trip carefully timed for another fine old hickory along the Conodoguinet—an Indian-named stream of angles, curves, many trees and much beauty—had brought me to the quickly passing bloom feast of this noble American tree. The leaves were about half-grown and half-colored, which means that they displayed an elegance of texture and hue most pleasing to see. And the flowers—there they were, hanging under the twigs in long clusters of what I might describe as ends of chenille, if it were not irreverent to compare these delicate greenish catkins with anything man-made!



This fine shagbark was kind to the cameraman, for some of its lower branches drooped and hung down close enough to the "bars" of the rail fence to permit the photographic eye to be turned on them. Then came the tantalizing wait for stillness! I have frequently found that a wind, absolutely unnoticeable before, became obtrusively strong just when the critical moment arrived, and I have fancied that the lightly hung leaflets I have waited upon fairly shook with merriment as they received the gentle zephyr, imperceptible to my heated brow, but vigorous enough to keep them moving. Often, too—indeed nearly always—I have found that after exhausting my all too scanty stock of patience, and making an "exposure" in despair, the errant blossoms and leaflets would settle down into perfect immobility, as if to say, "There! don't be cross—we'll behave," when it was too late.

But the shagbark at last was good to me, and I could leave with the comfortable feeling that I was carrying away a little bit of nature's special work, a memorandum of her rather private processes of fruit-making, without injuring any part of the inspected trees. It has been a sorrow to me that I have not seen that great hickory later in the year, when the clusters of tassels have become bunches of husk-covered nuts. To get really acquainted with any tree, it should be visited many times in a year. Starting with the winter view, one observes the bark, the trend and character of the limbs, the condition of the buds. The spring opening of growth brings rapid changes, of both interest and beauty, to be succeeded by the maturity of summer, when, with the ripened foliage overhead, everything is different. Again, when the fruit is on, and the touch of Jack Frost is baring the tree for the smoother passing of the winds of winter, there is another aspect. I have great respect for the tree-lover who knows unerringly his favorites at any time of the year, for have I not myself made many mistakes, especially when no leaves are at hand as pointers? The snow leaves nothing to be seen but the cunning framework of the tree—tell me, then, is it ash, or elm, or beech? Which is sugar-maple, and which red, or sycamore?

One summer walk in the deep forest, my friend the doctor, who knows many things besides the human frame, was puzzled at a sturdy tree bole, whose leaves far overhead mingled so closely with the neighboring greenery of beech and birch that in the dim light they gave no help. First driving the small blade of his pocket-knife deep into the rugged bark of the tree in question, he withdrew it, and then smelled and tasted, exclaiming, "Ah, I thought so; it is the wild cherry!" And, truly, the characteristic prussic-acid odor, the bitter taste, belonging to the peach and cherry families, were readily noted; and another Sherlock Holmes tree fact came to me!

Of other hickories I know little, for the false shagbark, the mockernut, the pignut, and the rest of the family have not been disclosed to me often enough to put me at ease with them. There are to be more tree friends, both human and arborescent, and more walks with the doctor and the camera, I hope!

We of the cold North, as we crack the toothsome pecan, hardly realize its kinship with the hickory. It is full brother to our shellbark, which is, according to botany, Hicoria ovata, while the Southern tree is Hicoria pecan. A superb tree it is, too, reaching up amid its vigorous associates of the forests of Georgia, Alabama and Texas to a height exceeding one hundred and fifty feet. Its upright and elegant form, of a grace that conceals its great height, its remarkable usefulness, and its rather rapid growth, commend it highly. The nut-clusters are striking, having not only an interesting outline, but much richness of color, in greens and russets.



It may seem odd to include the beech under the nut-bearing trees, to those of us who know only the nursery-grown forms of the European beech, "weeping" and twisted, with leaves of copper and blood, as seen in parks and pleasure-grounds. But the squirrels would agree; they know well the sweet little triangular nuts that ripen early in fall.

The pure American beech, uncontaminated and untwisted with the abnormal forms just mentioned, is a tree that keeps itself well in the eye of the woods rambler; and that eye is always pleasured by it, also. Late in winter, the light gray branches of a beech thicket on a dry hillside on the edge of my home city called attention to their clean elegance amid sordid and forbidding surroundings, and it was with anger which I dare call righteous that I saw a hideous bill-board erected along the hillside, to shut out the always beautiful beeches from sight as I frequently passed on a trolley car! I have carefully avoided buying anything of the merchants who have thus set up their announcements where they are an insult; and it might be noted that these and other offensive bill-boards are to others of like mind a sort of reverse advertising—they tell us what not to purchase.



Years ago I chanced to be present at a birth of beech leaves, up along Paxton Creek. It was late in the afternoon, and our reluctant feet were turning homeward, after the camera had seen the windings of the creek against the softening light, when the beeches over-arching the little stream showed us this spring marvel. The little but perfectly formed leaves had just opened, in pairs, with a wonderful covering of silvery green, as they hung downward toward the water, yet too weak to stand out and up to the passing breeze. The exquisite delicacy of these trembling little leaves, the arching elegance of the branches that had just opened them to the light, made it seem almost sacrilegious to turn the lens upon them.

Often since have I visited the same spot, in hope to see again this awakening, but without avail. The leaves show me their silky completeness, rustling above the stream in softest tree talk; the curious staminate flower-clusters hang like bunches of inverted commas; the neat little burs, with their inoffensive prickles, mature and discharge the angular nuts—but I am not again, I fear, to be present at the hour of the leaf-birth of the beech's year.

The beech, by the way, is tenacious of its handsome foliage. Long after most trees have yielded their leaves to the frost, the beech keeps its clothing, turning from the clear yellow of fall to lightest fawn, and hanging out in the forest a sign of whiteness that is cheering in the winter and earliest spring. These bleached-out leaves will often remain until fairly pushed off by the opening buds of another year.



Of the hazelnut or filbert, I know nothing from the tree side, but I cannot avoid mentioning another botanically unrelated so-called hazel—the witch-hazel. This small tree is known to most of us only as giving name to a certain soothing extract. It is worthy of more attention, for its curious and delicately sweet yellow flowers, seemingly clusters of lemon-colored threads, are the very last to bloom, opening bravely in the very teeth of Jack Frost. They are a delight to find, on the late fall rambles; and the next season they are followed by the still more curious fruits, which have a habit of suddenly opening and fairly ejaculating their seeds. A plucked branch of these fruits, kept in a warm place a few hours, will show this—another of nature's efficient methods for spreading seeds, in full operation—if one watches closely enough. The flowers and the fruits are on the tree at the same time, just as with the orange of the tropics.

Speaking of a tropical fruit, I am reminded that the greatest nut of all, though certainly not an American native, is nevertheless now grown on American soil. Some years ago a grove of lofty cocoanut palms in Yucatan fascinated me, and the opportunity to drink the clear and refreshing milk (not milky at all, and utterly different from the familiar contents of the ripened nut of commerce) was gladly taken. Now the bearing trees are within the bounds of the United States proper, and the grand trees in Southern Florida give plenty of fruit. The African citizens of that neighborhood are well aware of the refreshing character of the "juice" of the green cocoanut, and a friend who sees things for me with a camera tells with glee how a "darky" at Palm Beach left him in his wheel-chair to run with simian feet up a sloping trunk, there to pull, break open, and absorb the contents of a nut, quite as a matter of course. I have myself seen the Africans of the Bahamas in the West Indies climbing the glorious cocoa palms of the coral keys, throwing down the mature nuts, and then, with strong teeth, stripping the tough outer covering to get at the refreshing interior.

All these nut trees are only members of the great family of trees given by God for man's good, I firmly believe; for man first comes into Biblical view in a garden of trees, and the city and the plain are but penances for sin!



Some Other Trees

In preceding chapters of this series I have treated of trees in a relationship of family, or according to some noted similarity. There are, however, some trees of my acquaintance of which the family connections are remote or unimportant, and there are some other trees of individual merit with the families of which I am not sufficiently well acquainted to speak familiarly as a whole. Yet many of these trees, looked at by themselves, are as beautiful, interesting, and altogether worthy as any of which I have written, and they are also among the familiar trees of America. Therefore I present a few of them apart from the class treatment.

* * * * *

One day in very early spring—or was it very late in winter?—I walked along the old canal road, looking for some evidence in tree growth that spring was really at hand. Buds were swelling, and here and there a brave robin could be heard telling about it in song to his mate (I think that settled the season as earliest spring!); but beyond the bud evidences the trees seemed to be silent on the subject. Various herbs showed lusty beginnings, and the skunk-cabbage, of course, had pushed up its tropical richness in defiance of any late frost, pointing the way to its peculiar red-purple flowers, long since fertilized and turning toward maturity.

The search seemed vain, until a glint of yellow just ahead, too deep to proceed from the spice-bush I was expecting to find, drew me to the very edge of the water, there to see hanging over and reflected in the stream a mass of golden catkins. Looking closely, and touching the little tree, I disengaged a cloud of pollen and a score of courageous bees, evidently much more pleased with the sweet birch than with the near-by skunk-cabbage flowers. Sweet birch it was; the stiff catkins, that had all winter held themselves in readiness, had just burst into bloom with the sun's first warmth, introducing a glint of bright color into the landscape, and starting the active double work of the bees, in fertilizing flowers while gathering honey, that was not to be intermitted for a single sunshine hour all through the season.

A little later, along the great Susquehanna, I found in full bloom other trees of this same birch, beloved of boys—and of girls—for its aromatic bark. Certainly picturesque and bright, the little trees were a delight to the winter-wearied eye, the mahogany twigs and the golden catkins, held at poise over the water, being full of spring suggestion.

All of the birches—I wish I knew them better!—are good to look at, and I think the bees, the woodpeckers, the humming-birds and other wood folk must find some of them good otherwise. At Eagles Mere there was a yellow birch in the bark of which scores of holes had been drilled by the woodpeckers or the bees, at regularly spaced intervals, to let the forest life drink at will of the sweet sap. I remember also that my attempt to photograph a score of bees, two large brown butterflies and one humming-bird, all in attendance upon this birch feast, was a surprising failure. I secured a picture of the holes in the bark, to be sure, but the rapidly moving insect and bird life was too quick for an exposure of even a fraction of a second, and my negative was lifeless. These same yellow birches, picturesque in form, ragged in light-colored bark, give a brightness all their own to the deep forest, mostly of trees with rather somber bark.

A woodsman told me one summer of the use of old birch bark for starting a fire in the wet woods, and I have since enjoyed collecting the bark from fallen trees in the forest. It strips easily, in large pieces, from decayed stems, and when thrown on an open fire, produces a cheery and beautiful blaze, as well as much heat; while, if cunningly handled, by its aid a fire can be kindled even in a heavy rain.



The great North Woods show us wonderful birches. Paddling through one of the Spectacle ponds, along the Racquette river, one early spring day, I came upon a combination of white pine, red pine, and paper-birch that was simply dazzling in effect. This birch has bark, as every one knows, of a shining creamy white. Not only its color, but its tenacity, resistance to decay, and wonderful divisibility, make this bark one of the most remarkable of nature's fabrics. To the Indian and the trapper it has long been as indispensable as is the palm to the native of the tropics.



There are other good native birches, and one foreigner—the true white birch—whose cut-leaved form, a familiar lawn tree of drooping habit, is worth watching and liking. The name some of the nurserymen have given it, of "nine-bark," is significantly accurate, for at least nine layers may be peeled from the glossy whiteness of the bark of a mature tree.

I intend to know more of the birches, and to see how the two kinds of flowers act to produce the little fruits, which are nuts, though they hardly look so. And I would urge my tree-loving friends to plant about their homes these cheery and most elegantly garbed trees.

The spice-bush, of which I spoke above, is really a large shrub, and is especially notable for two things—the way it begins the spring, and the way it ends the fall. About my home, it is the first of wild woods trees to bloom, except perhaps the silver maple, which has a way of getting through with its flowers unnoticed before spring is thought of. One finds the delicate little bright yellow flowers of the spice-bush clustered thickly along the twigs long before the leaves are ready to brave the chill air. After the leaves have fallen in the autumn, these flowers stand out in a reincarnation of scarlet and spicy berries, which masquerade continually as holly berries when cunningly introduced amid the foliage of the latter. Between spring and fall the spice-bush is apparently invisible.



How many of us, perfectly familiar with "the holly berry's glow" about Christmas time, have ever seen a whole tree of holly, set with berries? Yet the trees, sometimes fifty feet high, of American holly—and this is very different from the English holly in leaf—grow all along the Atlantic sea-board, from Maine to Florida, and are especially plenty south of Maryland and Delaware. There is one superb specimen in Trenton, New Jersey's capital, which is of the typical form, and when crowded with scarlet berries it is an object of great beauty. One reason why many of us have not seen holly growing in the wild is that it seems to prefer the roughest and most inaccessible locations. Years ago I was told that I might see plenty of holly growing freely in the Pennsylvania county of my home. "But," my informant added, "you will need to wear heavy leather trousers to get to it!" The nurserymen are removing this difficulty by growing plants of all the hollies—American, Japanese, English and Himalayan—so that they may easily be set in the home grounds, with their handsome evergreen foliage and their berries of red or black.



One spring, the season and my opportunities combined to provide a most pleasing feast of color in the tree quest. It was afforded by the juxtaposition at Conewago of the bloom-time of the deep pink red-bud, miscalled "Judas tree," and the large white dogwood,—both set against the deep, almost black green of the American cedar, or juniper. These two small trees, the red-bud and the dogwood, are of the class of admirable American natives that are notable rather for beauty and brightness of bloom than for tree form or size.

The common dogwood—Cornus florida of the botany—appears in bloom insidiously, one might say; for the so-called flowers open slowly, and they are green in color, and easily mistaken for leaves, after they have attained considerable size. Gradually the green pales to purest white, and the four broad bracts, with the peculiar little pucker at the end of each, swell out from the real flowers, which look like stamens, to a diameter of often four inches. With these flowers clustered thickly on the usually flat, straight branches, the effect against the green or brown of near-by trees is startling. The dogwood's horizontal branching habit makes every scrap of its lovely white blooms effective to the beholder on the ground below, but far more striking if one may see it from above, as looking down a hillside.

Though the dogwood blooms before its leaves are put forth, the foliage sometimes catches up with the flowers; and this foliage is itself a pleasure, because of its fineness and its regular venation, or marking with ribs. In the fall, when the flowers of purest white have been succeeded by oblong berries of brightest scarlet, the foliage remains awhile to contrast with the brilliance of the fruit. The frosts soon drop the leaves, and then the berries stand out in all their attractiveness, offering food to every passing bird, and thus carrying out another of nature's cunning provisions for the reproduction of the species. Seeds in the crops of birds travel free and far, and some fall on good ground!

Is it not sad to know that the brave, bold dogwood, holding out its spring flag of truce from arduous weather, and its autumn store of sustenance for our feathered friends, is in danger of extinction from the forest because its hardy, smooth, even-grained white wood has been found to be especially available in the "arts"? I feel like begging for the life of every dogwood, as too beautiful to be destroyed for any mere utility.



I have been wondering as to the reason for the naming of the cornuses as dogwoods, and find in Bailey's great Cyclopedia of Horticulture the definite statement that the name was attached to an English red-branched species because a decoction of the bark was used to wash mangy dogs! This is but another illustration of the inadequacy and inappropriateness of "common" names.

There are many good dogwoods—the Cornus family is admirable, both in its American and its foreign members—but I must not become encyclopedic in these sketches of just a few tree favorites. I will venture to mention one shrub dogwood—I never heard its common name, but it has three botanical names (Cornus sericea, or coerulea, or Amomum, the latter preferred) to make up for the lack. It ought to be called the blue-berried dogwood, by reason of its extremely beautiful fruit, which formed a singular and delightful contrast to the profusion of red and scarlet fruits so much in evidence, one September day, in Boston's berry-full Franklin Park.



The red-bud, as I have said, is miscalled Judas-tree, the tradition being that it was on a tree of this family, but not of the American branch, happily and obviously, that the faithless disciple hanged himself after his final interview with the priests who had played upon his cupidity. Indeed, tradition is able to tell even now marvelous stories to travelers, and not long ago I was more amused than edified to hear an eloquent clergyman just returned from abroad tell how he had been shown the fruits of the Judas-tree, "in form like beautiful apples, fair to the eye, but within bitter and disappointing;" and he moralized just as vigorously on this fable as if it had been true, as he thought it. He didn't particularly relish the suggestion that the pulpit ought to be fairly certain of its facts, whether of theology or of science, in these days; but he succumbed to the submission of authority for the statement that the Eastern so-called Judas-tree, Cercis siliquastrum, bore a small pod, like a bean, and was not unpleasant, any more than the pod was attractive.

I mention this only in reprobation of the unpleasant name that really hurts the estimation of one of the most desirable and beautiful of America's smaller trees. The American red-bud is a joy in the spring about dogwood time, for it is all bloom, and of a most striking color. Deep pink, or purplish light red, or clear bright magenta—all these color names fit it approximately only. One is conscious of a warm glow in looking toward the little trees, with every branch clear down to the main stem not only outlined but covered with richest color.

There is among the accompanying illustrations (page 201) a photograph of a small but characteristic red-bud in bloom, looking at which reminds me of one of the pleasantest experiences of my outdoor life. With a cameristic associate, I was in a favorite haunt, seeing dogwoods and red-buds and other things of spring beauty, when a sudden warm thunder shower overtook us. Somewhat protected in our carriage—and it would have been more fun if we had stood out to take the rain as comfortably as did the horse—we saw the wonder of the reception of a spring shower by the exuberant plant life we were there to enjoy. When the clouds suddenly obscured the sky, and the first drops began to fall, the soft new umbrellas of the May-apples, raised to shield the delicate white flowers hidden under them from the too ardent sunshine, reversed the usual method by closing tightly and smoothly over the blooms, thus protecting perfectly their pollen hearts, and offering little resistance to the sharp wind that brought the rain. At our very feet we could see the open petals of the spring beauty coil up into tight little spirals, the young leaves on the pin-oaks draw in toward the stems from which they had been expanding. Over the low fence, the blue phlox, that dainty carpeting of the May woods, shut its starry flowers, and lay close to the ground. Quiet as we were, we could see the birds find sheltered nooks in the trees about us.

But soon the rain ceased, the clouds passed away, and the sun shone again, giving us a rainbow promise on the passing drops. Everything woke up! The birds were first to rejoice, and a veritable oratorio of praise and joyfulness sounded about our ears. The leaves quickly expanded, fresher than ever; the flowers uncurled and unfolded, the May-apple umbrellas raised again; and all seemed singing a song as joyous as that of the birds, though audible only to the nerves of eye and brain of the human beings who had thus witnessed another of nature's interior entertainments.

How much we miss by reason of fear of a little wetting! Many of the finest pictures painted by the Master of all art are visible only in rain and in mist; and the subtlest coloring of tree leaf and tree stem is that seen only when the dust is all washed away by the shower that should have no terrors for those who care for the truths of nature. In these days of rain-proof clothing, seeing outdoors in the rain is not even attended by the slightest discomfort, and I have found my camera quite able to stand a shower!

Another of the early spring-flowering small trees—indeed, the earliest one that blooms in white—is the shad-bush, or service-berry. Again the "common" names are trifling and inadequate; shad-bush because the flowers come when the shad are ascending the rivers along which the trees grow, and service-berry because the pleasant fruits are of service, perhaps! June-berry, another name, is better; but the genus owns the mellifluous name of Amelanchier, and the term Canadensis belongs to the species with the clouds of little white flowers shaped like a thin-petaled star. The shad-bush blooms with the trilliums—but I may not allow the spring flowers to set me spinning on another hank!



Searching for early recollections of trees, I remember, when a boy of six or seven, finding some little green berries or fruits, each with its long stem, on the pavement under some great trees in the Capitol Park of my home town. I could eat these; and thus they pleased the boy as much as the honey-sweet flowers that gave rise to them now please the man. The noble American linden, one of the really great trees of our forests, bears these delicate whitish flowers, held in rich clusters from a single stem which is attached for part of its length to a curious long green bract. If these flowers came naked on the tree, as do those of the Norway maple, for instance, they would be easily seen and admired of men, but being withheld until the splendid heart-shaped foliage is well out, the blooms miss the casual eye. But the bees see them; they know the linden for their own, and great stores of sweetest honey follow a year when abundant pasture of these flowers is available.



A kindly tree is this linden, or lime, or basswood, to give it all its common names. Kindly as well as stately, but never rugged as the oak, or of obvious pliant strength as the hickory. The old tree invites to shade under its limbs crowded with broad leaves; the young tree is lusty of growth and clean of bark, a model of rounded beauty and a fine variant from the overworked maples of our streets.

Again, the tale of woe! for the great lindens of our forests are nearly all gone. Too useful for timber; too easy to fell; its soft, smooth, even wood too adaptable to many uses! Cut them all; strip the bark for "bast," or tying material; America is widening; the sawmills cannot be idle; scientific and decent forestry, so successful and so usual in Europe, is yet but a dream for future generations here in America!

But other lindens, those of Europe especially, are loved of the landscape architect and the Germans. "Unter den Linden," Berlin's famous street, owes its name, fame and shade to the handsome European species, the white-lined leaves of which turn up in the faintest breeze, to show silvery against the deep green of their upper surfaces. Very many of these fine lindens are being planted now in America by landscape architects, and there are some lindens on Long Island just as prim and trim as any in Berlin. Indeed, there is a sort of German "offiziere" waxed-mustache air of superiority about them, anyway!



There is an all-pervading Middle States tree that I might give a common name to as the "fence-post tree," because it is so often grown for that use only, by reason of its enduring timber and its exceeding vigor under hard usage. Yet the common black locust is one of the most distinct and pleasing American trees of moderate height. Distinct it is in its framework in winter, mayhap with the twisted pods of last season's fruits hanging free; distinct again in its long-delayed late-coming acacia-like foliage; but fragrant, elegant and beautiful, as well as distinct, when in June it sets forth its long, drooping racemes of whitest and sweetest flowers. These come only when warm weather is an assured fact, and the wise Pennsylvania Germans feel justified in awaiting the blooming of the locust before finally discarding their winter underclothing!

For years a family of my knowledge has held it necessary, for its proper conduct, to have in order certain floral drives. First the apple blossom drive introduces the spring, and the lilac drive confirms the impression that really the season is advancing; but the locust drive is the sweetest of all, taking these nature lovers along some shady lanes, beside the east bank of a great river, and in places where, the trees planted only for the fence utility of the hard yellow wood, these fragrant flowers, hanging in grace and elegance far above the highway, have redeemed surroundings otherwise sordid and mean.



I want Americans to prize the American locust for its real beauty. The French know it, and show with pride their trifling imported specimens. We cannot exterminate the trees, and there will be plenty for posts, too; but let us realize its sweetness and elegance, as well as the durability of its structure.



There are fashions in trees, if you please, and the nurserymen set them. Suddenly they discover the merits of some long-forgotten tree, and it jumps into prominence. Thus, only a few years ago, the pin-oak came into vogue, to the lasting benefit of some parks, avenues and home grounds. Then followed the sycamore, but it had to be the European variety, for our own native "plane tree," or "button-ball," is too plentiful and easy to sing much of a tree-seller's song about. This Oriental plane is a fine tree, however, and the avenue in Fairmount Park that one may see from trains passing over the Schuylkill river is admirable. The bark is mottled in green, and especially bright when wet with rain. As the species is free from the attacks of a nasty European "bug," or fungus, which is bothering the American plane, it is much safer to handle, commercially.

But our stately American sycamore is in a different class. One never thinks of it as a lawn tree, or as bordering a fashionable roadway; rather the expectation is to find it along a brook, in a meadow, or in some rather wild and unkempt spot. As one of the scientific books begins of it, "it is a tree of the first magnitude." I like that expression; for the sycamore gives an impression of magnitude and breadth; it spreads out serenely and comfortably.

My friend Professor Bailey says Platanus occidentalis, which is the truly right name of this tree, has no title to the term sycamore; it is properly, as his Cyclopedia gives it, Buttonwood, or Plane. Hunting about a little among tree books, I find the reason for this, and that it explains another name I have never understood. The sycamore of the Bible, referred to frequently in the Old Testament, traditionally mentioned as the tree under which Joseph rested with Mary and the young child on the way to Egypt, and into which Zaccheus climbed to see what was going on, was a sort of fig tree—"Pharaoh's Fig," in fact. When the mystery-plays of the centuries gone by were produced in Europe, the tree most like to what these good people thought was the real sycamore furnished the branches used in the scene-setting—and it was either the oriental plane, or the sycamore-leaved maple that was chosen, as convenient. The name soon attached itself to the trees; and when homesick immigrants looked about the new world of America for some familiar tree, it was easy enough to see a great similarity in our buttonwood, which thus soon became sycamore.



So much for information, more or less legendary, I confess; but the great tree we are discussing is very tangible. Indeed, it is always in the public eye; for it carries on a sort of continuous disrobing performance! The snake sheds his skin rather privately, and comes forth in his new spring suit all at once; the oak and the maple, and all the rest of them continually but invisibly add new bark between the splitting or stretching ridges of the old; but our wholesome friend the sycamore is quite shamelessly open about it, dropping off a plate or a patch here and there as he grows and swells, to show us his underwear, which thus at once becomes overcoat, as he goes on. At first greenish, the under bark thus exposed becomes creamy white, mostly; and I have had a conceit that the colder the winter, the whiter would be those portions of Mr. Buttonball's pajamas he cared to expose to us the next spring!



The leaves of the sycamore are good to look at, and efficient against the sun. The color above is not as clear and sharp as that of the maple; underneath the leaves are whitish, and soft, or "pubescent," as the botanical term goes. Quite rakishly pointed are the tips, and the whole effect, in connection with the balls,—which are first crowded clusters of flowers, and then just as crowded clusters of seeds—is that of a gentleman of the old school, dignified in his knee-breeches and cocked hat, fully aware that he is of comfortable importance!

Those little button-balls that give name to this good American tree follow the flower clusters without much change of form—they were flowers, they are seeds—and they stay by the tree persistently all winter, blowing about in the sharp winds. After a while one is banged often enough to open its structure, and then the carrying wind takes on its wings the neat little cone-shaped seeds, each possessed of its own silky hairs to help float it gently toward the ground—and thus is another of nature's curious rounds of distribution completed.

A tree is never without interest to those whose eyes have been opened to some of the wonders and perfections of nature. Nevertheless, there is a time in the year's round when each tree makes its special appeal. It may be in the winter, when every twig is outlined sharply against the cold sky, and the snow reflects light into the innermost crevices of its structure, that the elm is most admirable. When the dogwood has on its white robe in May and June, it then sings its song of the year. The laden apple tree has a pure glory of the blossoms, and another warmer, riper glory of the burden of fruit, but we think most kindly of its flowering time. Some trees maintain such a continuous show of interest and beauty that it is difficult to say on any day, "Now is this tulip or this oak at its very finest!" Again, the spring redness of the swamp maple is hardly less vivid than its mature coloring of the fall.

But as to the liquidambar, or sweet-gum, there can be no question. Interesting and elegant the year round, its autumn covering of polished deep crimson starry leaves is so startlingly beautiful and distinct as to almost take it out of comparison with any other tree. Others have nearly the richness of color, others again show nearly the elegance of leaf form, but no one tree rivals completely the sweet-gum at the time when the autumn chill has driven out all the paleness in its leaf spectrum, leaving only the warm crimson that seems for awhile to defy further attacks of frost.

As to shape, the locality settles that; for, a very symmetrical small to maximum-sized tree in the North and on high dry places, in the South and in wet places north it becomes another "tree of the first magnitude," wide-spreading and heavy. A stellar comparison seems to fit, because of these wonderful leaves. They struck me at first, hunting photographs one day, as some sort of a maple; but what maple could have such perfection of star form? A maple refined, perfected, and indeed polished, one might well think, for while other trees have shining leaves, they are dull in comparison with the deep-textured gloss of these of the sweet-gum.



Here, too, is a tree for many places; an adaptable, cosmopolitan sort of arboreal growth. At its full strength of hard, solid, time-defying wooded body on the edge of some almost inaccessible swamp of the South, where its spread-out roots and ridgy branches earn for it another common name as the "alligator tree," it is in a park or along a private driveway at the North quite the acme of refined tree elegance, all the summer and fall. It takes on a rather narrow, pyramidal head, broadening as it ages, but never betraying kin with its fellow of the swamp, save perhaps when winter has bared its peculiar winged and strangely "corky" branches.



These odd branches bear, on some trees particularly, a noticeable ridge, made up of the same substance which in the cork-oak of Europe furnishes the bottle-stoppers of commerce. It makes the winter structure of the sweet-gum most distinct and picturesque, which appearance is accentuated by the interesting little seed-balls, or fruits, rounded and spiny, that hang long from the twigs. These fruits follow quickly an inconspicuous flower that in April or May has made its brief appearance, and they add greatly to the general attractiveness of the tree on the lawn, to my mind. Years ago I first made acquaintance with the liquidambar, as it ought always to be called, one wet September day, when an old tree-lover took me out on his lawn to see the rain accentuate the polish on the starry leaves and drip from the little many-pointed balls. I found that day that a camera would work quite well under an umbrella, and I obtained also a mind-negative that will last, I believe, as long as I can think of trees.

The next experience was in another state, where a quaint character, visited on business, struck hands with me on tree-love, and took me to see his pet liquidambar at the edge of a mill-pond. That one was taller, and quite stately; it made an impression, deepened again when the third special showing came, this time on a college campus, the young tree being naked and corky, and displayed with pride by the college professor who had gotten out of his books into real life for a joyous half day.

He wasn't the botany professor, if you please; that dry-as-dust gentleman told me, when I inquired as to what I might find in early bloom, or see with the eyes of an ignorant plant-lover, that there was "nothing blooming, and nothing of interest." He added that he had a fine herbarium where I might see all the plants I wanted, nicely dried and spread out with pins and pasters, their roots and all!

Look at dead plants, their roots indecently exposed to mere curiosity, on a bright, living early April day? Not much! I told my trouble to the professor of agriculture, whose eyes brightened, as he informed me he had no classes for that morning, and—"We would see!" We did see a whole host of living things outdoors,—flowers peeping out; leaves of the willows, just breaking; buds ready to burst; all nature waiting for the sun's call of the "grand entree." It was a good day; but I pitied that poor old dull-eyed herbarium specimen of a botanical professor, in whose veins the blood was congealing, when everything about called on him to get out under the rays of God's sun, and study, book in hand if he wanted, the bursting, hurrying facts of the imminent spring.

But a word more about the liquidambar—the name by which I hope the tree we are discussing may be talked of and thought of. Old Linnaeus gave it that name, because it described euphoniously as well as scientifically the fact that the sap which exudes from this fine American tree is liquid amber. Now isn't that better than "gum" tree?

With trees in general as objects of interest, I have always felt a special leaning toward tropical trees, probably because they were rare, and indeed not to be seen outside of the conservatory in our Middle States. My first visit to Florida was made particularly enjoyable by reason of the palms and bananas there to be seen, and I have by no means lost the feeling of admiration for the latter especially. In Yucatan there were to be seen other and stranger growths and fruits, and the novelty of a great cocoanut grove is yet a memory not eclipsed by the present-day Floridian and Bahamian productions of the same sort.

It was, therefore, with some astonishment that I came to know, a few years ago, more of a little tree bearing a fruit that had been familiar from my boyhood, but which I was then informed was the sole northern representative of a great family of tropical fruits, and which was fairly called the American banana. The papaw it was; a fruit all too luscious and sweet, when fully ripe in the fall, for most tastes, but appealing strongly to the omnivorous small boy. I suppose most of my readers know its banana-like fruits, four or five inches long, green outside, but filled with soft and sweet aromatic yellow pulp, punctuated by several fat bean-like seeds.



But it is the very handsome and distinct little tree, with its decidedly odd flowers, I would celebrate, rather than the fruits. This tree, rather common to shady places in eastern America as far north as New York, is worth much attention, and worth planting for its spreading richness of foliage. The leaves are large, and seem to carry into the cold North a hint of warmth and of luxuriant growth not common, by any means—I know of only one other hardy tree, the cucumber magnolia, with an approaching character. The arrangement of these handsome papaw leaves on the branches, too, makes the complete mass of regularly shaped greenery that is the special characteristic of this escape from the tropics; and, since I have seen the real papaw of the West Indies in full glory, I am more than ever glad for the handsomer tree that belongs to the regions of cold and vigor.



The form of our papaw, or Asimina triloba—the botanical name is rather pleasing—is noticeable, and as characteristic as its leafage. See these side branches, leaving the slender central stem with a graceful up-curve, but almost at once swinging down, only to again curve upward at the ends! Are they not graceful? Such branches as these point nature's marvelous engineering, to appreciate which one needs only to try to imagine a structure of equal grace and efficiency, made with any material of the arts. How awkward and clumsy steel would be, or other metal!

Along these swinging curved branches, as we see them in the April winds, there appear hints of the leaf richness that is to come—but something else as well. These darkest purple-red petals, almost black, as they change from the green of their opening hue, make up the peculiar flowers of the papaw. There is gold in the heart of the flower, not hid from the bees, and there is much of interest for the seeker for spring knowledge as well; though I advise him not to smell the flowers. Almost the exact antithesis of the dogwood is the bloom of this tree; for, both starting green when first unfolded from the buds, the papaw's flowers advance through browns and yellows, dully mingled, to the deep vinous red of maturity. The dogwood's final banner of white is unfolded through its progress of greens, about the same time or a little later.

A pleasant and peculiar small tree is this papaw, not nearly so well known or so highly esteemed as it ought to be.

Another tree with edible fruits—but here there will be a dispute, perhaps!—is the persimmon. I mean the American persimmon, indissolubly associated in our own Southland with the darky and the 'possum, but also well distributed over Eastern North America as far north as Connecticut. The botanical name of the genus is Diospyros, liberally translated as "fruit of the gods," or "Jove's fruit." If his highness of Olympus was, by any chance, well acquainted with our 'simmon just before frost, he must have had a copper-lined mouth, to choose it as his peculiar fruit!

Making a moderate-sized tree of peculiar and pleasing form, its branches twisting regardless of symmetry, the persimmon in Pennsylvania likes the country roadsides, especially along loamy banks. Here it has unequaled opportunity for hanging out its attractively colored fruits. As one drives along in early fall, just before hard frost, these fine-looking little tomato-like globes of orange and red are advertised in the wind by the absence of the early dropping foliage. They look luscious and tempting; indeed, they are tempting! Past experience—you need but one—had prepared me for this "bunko" fruit; but my friend would not believe me, one day in early October—he must taste for himself. Taste he did, and generously, for the first bite is pleasing, and does not alarm, wherefore he had time, before his insulted nerves of mouth and tongue gave full warning, to absorb two of the 'simmons. Whew! What a face he made when the puckering juice got to work, and convinced him that he had been sucking a disguised lump of alum. Choking and gasping, he called for the water we were far from; and he won't try an unfrosted persimmon again!

My clerical friend who brought home the fairy tale about the red-bud, or Judas-tree, might well have based his story on the American persimmon, but for the fact that this puckery little globe, so brilliant and so deceptive before frost, loses both its beauty and its astringency when slightly frozen. Then its tender flesh is suave and delicious, and old Jove might well choose it for his own.



But the tree—that is a beauty all summer, with its shining leaves, oblong, pointed and almost of the magnolia shape. It will grace any situation, and is particularly one of the trees worth planting along highways, to relieve the monotony of too many maples, ashes, horse-chestnuts and the like, and to offer to the passer-by a tempting fruit of which he will surely not partake too freely when it is most attractive. I read that toward the Western limit of its range the persimmon, in Louisiana, Eastern Kansas and the Indian Territory, becomes another tree of the first magnitude, towering above a hundred feet. This would be well worth seeing!

There is another persimmon in the South, introduced from Japan, the fruits of which are sold on the fruit-stands of Philadelphia, Boston and New York. This, the "kaki" of Japan, is a small but business-like tree, not substantially hardy north of Georgia, which provides great quantities of its beautiful fruits, rich in coloring and sweet to the taste, and varying greatly in size and form in its different varieties. These 'simmons do not need the touch of frost, nor do they ever attain the fine, wild, high flavor of the frost-bitten Virginian fruits; the tree that bears them has none of the irregular beauty of our native persimmon, nor does it approach in size to that ornament of the countryside.

* * * * *

And now, in closing these sketches, I become most keenly sensible of their deficiencies. Purely random bits they are, coming from a busy man, and possessing the one merit of frankness. Deeply interested in trees, but lacking the time for continuous study, I have been turning my camera and my eyes upon the growths about me, asking questions, mentally recording what I could see, and, while thankful for the rest and the pleasure of the pursuit, always sorry not to go more fully into proper and scientific tree knowledge. At times my lack in this respect has made me ashamed to have written at all upon trees; but with full gratitude to the botanical explorers whose labors have made such superficial observations as mine possible, I venture to send forth these sketches, without pretension as to the statement of any new facts or features.



If anything I have here set down shall induce among those who have looked and read with me from nature's open book the desire to go more deeply into the fascinating tree lore that always awaits and inevitably rewards the effort, I shall cry heartily, "God-speed!"
