[319] In works written on the pigeon by fanciers I have sometimes observed the mistaken belief expressed that the species which naturalists call ground-pigeons (in contradistinction to arboreal pigeons) do not perch and build on trees. In these same works wild species resembling the chief domestic races are often said to exist in various parts of the world, but such species are quite unknown to naturalists.

[334] I have drawn out a long table of the various crosses made by fanciers between the several domestic breeds, but I do not think it worth publishing. I have myself made for this special purpose many crosses, and all were perfectly fertile. I have united in one bird five of the most distinct races, and with patience I might undoubtedly have thus united all. The case of five distinct breeds being blended together with unimpaired fertility is important, because Gaertner has shown that it is a very general, though not, as he thought, universal rule, that complex crosses between several species are excessively sterile. I have met with only two or three cases of reported sterility in the offspring of certain races when crossed. Von Pistor ('Das Ganze der Feld-taubenzucht,' 1831, s. 15) asserts that the mongrels from barbs and fantails are sterile: I have proved this to be erroneous, not only by crossing these hybrids with several other hybrids of the same parentage, but by the more severe test of pairing brother and sister hybrids inter se, and they were perfectly fertile. Temminck has stated ('Hist. Nat. Gen. des Pigeons,' tom. i. p. 197) that the turbit or owl will not cross readily with other breeds: but my turbits crossed, when left free, with almond tumblers and with trumpeters; the same thing has occurred (Rev. E. S. Dixon, 'The Dovecot,' p. 107) between turbits and dovecots and nuns. I have crossed turbits with barbs, as has M. Boitard (p. 34), who says the hybrids were very fertile. Hybrids from a turbit and fantail have been known to breed inter se (Riedel, Taubenzucht, s. 25, and Bechstein, 'Naturgesch. Deutsch.' B. iv. s. 44). Turbits (Riedel, s. 26) have been crossed with pouters and with jacobins, and with a hybrid jacobin-trumpeter (Riedel, s. 27). The latter author has, however, made some vague statements (s. 22) on the sterility of turbits when crossed with certain other crossed breeds. But I have little doubt that the Rev. E. S. Dixon's explanation of such statements is correct, viz. that individual birds both with turbits and other breeds are occasionally sterile.

[335] 'Das Ganze der Taubenzucht,' s. 18.

[336] 'Les Pigeons,' &c., p. 35.

[337] Domestic pigeons pair readily with the allied C. oenas (Bechstein, 'Naturgesch. Deutschlands,' B. iv. s. 3); and Mr. Brent has made the same cross several times in England, but the young were very apt to die at about ten days old; one hybrid which he reared (from C. oenas and a male Antwerp carrier) paired with a dragon, but never laid eggs. Bechstein further states (s. 26) that the domestic pigeon will cross with C. palumbus, Turtur risoria, and T. vulgaris, but nothing is said of the fertility of the hybrids, and this would have been mentioned had the fact been ascertained. In the Zoological Gardens (MS. report to me from Mr. James Hunt) a male hybrid from Turtur vulgaris and a domestic pigeon "paired with several different species of pigeons and doves, but none of the eggs were good." Hybrids from C. oenas and gymnophthalmos were sterile. In Loudon's 'Mag. of Nat. Hist.' vol. vii. 1834, p. 154, it is said that a male hybrid (from Turtur vulgaris male, and the cream-coloured T. risoria female) paired during two years with a female T. risoria, and the latter laid many eggs, but all were sterile. MM. Boitard and Corbie ('Les Pigeons,' p. 235) state that the hybrids from these two turtle-doves are invariably sterile both inter se and with either pure parent. The experiment was tried by M. Corbie "avec une espece d'obstination;" and likewise by M. Manduyt, and by M. Vieillot. Temminck also found the hybrids from these two species quite barren. Therefore, when Bechstein ('Naturgesch. Vogel. Deutschlands,' B. 4, s. 101) asserts that the hybrids from these two turtle-doves propagate inter se equally well with pure species, and when a writer in the 'Field' newspaper (in a letter dated Nov. 10th, 1858) makes a similar assertion, it would appear that there must be some mistake; though what the mistake is I know not, as Bechstein at least must have known the white variety of T. risoria: it would be an unparalleled fact if the same two species sometimes produced extremely fertile, and sometimes extremely barren, offspring. In the MS. report from the Zoological Gardens it is said that hybrids from Turtur vulgaris and suratensis, and from T. vulgaris and Ectopistes migratorius, were sterile. Two of the latter male hybrids paired with their pure parents, viz. Turtur vulgaris and the Ectopistes, and likewise with T. risoria and with Columba oenas, and many eggs were produced, but all were barren. At Paris, hybrids have been raised (Isid. Geoffrey Saint Hilaire, 'Hist. Nat. Generale,' tom. iii. p. 180) from Turtur auritus with T. cambayensis and with T. suratensis; but nothing is said of their fertility. At the Zoological Gardens of London the Goura coronata and victoriae produced a hybrid, which paired with the pure G. coronata, and laid several eggs, but these proved barren. In 1860 Columba gymnophthalmos and maculosa produced hybrids in these same gardens.

[338] There is one exception to the rule, namely in a sub-variety of the swallow of German origin, which is figured by Neumeister, and was shown to me by Mr. Wicking. This bird is blue, but has not the black wing-bars; for our object, however, in tracing the descent of the chief races, this exception signifies the less as the swallow approaches closely in structure to C. livia. In many sub-varieties, the black bars are replaced by bars of various colours. The figures given by Neumeister are sufficient to show that, if the wings alone are blue, the black wing-bars appear.

[339] I have observed blue birds with all the above-mentioned marks in the following races, which seemed to be perfectly pure, and were shown at various exhibitions. Pouters, with the double black wing-bars, with white croup, dark bar to end of tail, and white edging to outer tail-feathers. Turbits, with all these same characters. Fantails, with the same; but the croup in some was bluish or pure blue: Mr. Wicking bred blue fantails from two black birds. Carriers (including the Bagadotten of Neumeister), with all the marks: two birds which I examined had white, and two had blue croups; the white edging to the outer tail-feathers was not present in all. Mr. Corker, a great breeder, assures me that, if black carriers are matched for many successive generations, the offspring become first ash-coloured, and then blue with black wing-bars. Runts of the elongated breed had the same marks, but the croup was pale blue; the outer tail-feathers had white edges. Neumeister figures the great Florence Runt of a blue colour with black bars. Jacobins are very rarely blue, but I have received authentic accounts of at least two instances of the blue variety with black bars having appeared in England: blue jacobins were bred by Mr. Brent from two black birds. I have seen common tumblers, both Indian and English, and short-faced tumblers, of a blue colour, with black wing-bars, with the black bar at the end of the tail, and with the outer tail-feathers edged with white; the croup in all was blue, or extremely pale blue, never absolutely white. Blue barbs and trumpeters seem to be excessively rare; but Neumeister, who may be implicitly trusted, figures blue varieties of both, with black wing-bars. Mr. Brent informs me that he has seen a blue barb; and Mr. H. Weir, as I am informed by Mr. Tegetmeier, once bred a silver (which means very pale blue) barb from two yellow birds.

[340] Mr. Blyth informs me that all the domestic races in India have the croup blue; but this is not invariable, for I possess a very pale blue Simmali pigeon with the croup perfectly white, sent to me by Sir W. Elliot from Madras. A slaty-blue and chequered Nakshi pigeon has some white feathers on the croup alone. In some other Indian pigeons there were a few white feathers confined to the croup, and I have noticed the same fact in a carrier from Persia. The Java fantail (imported into Amoy, and thence sent me) has a perfectly white croup.

[344] I could give numerous examples; two will suffice. A mongrel, whose four grandparents were a white turbit, white trumpeter, white fantail, and blue pouter, was white all over, except a very few feathers about the head and on the wings, but the whole tail and tail-coverts were dark bluish-grey. Another mongrel, whose four grandparents were a red runt, white trumpeter, white fantail, and the same blue pouter, was pure white all over, except the tail and upper tail-coverts, which were pale fawn, and except the faintest trace of double wing-bars of the same pale fawn tint.

[345] It deserves notice, as bearing on the general subject of variation, that not only C. livia presents several wild forms, regarded by some naturalists as species and by others as sub-species or as mere varieties, but that the species of several allied genera are in the same predicament. This is the case, as Mr. Blyth has remarked to me, with Treron, Palumbus, and Turtur.

This fact indicates the antiquity of the domestication in the East of the pigeon.

[387] I have consulted an eminent authority, Mr. Sclater, on this subject, and he thinks that I have not expressed myself too strongly. I am aware that one ancient author, Acosta, speaks of fowls as having inhabited S. America at the period of its discovery; and more recently, about 1795, Olivier de Serres speaks of wild fowls in the forests of Guiana; these were probably feral birds. Dr. Daniell tells me, he believes that fowls have become wild on the west coast of Equatorial Africa; they may, however, not be true fowls, but gallinaceous birds belonging to the genus Phasidus. The old voyager Barbut says that poultry are not natural to Guinea. Capt. W. Allen ('Narrative of Niger Expedition,' 1848, vol. ii. p. 42) describes wild fowls on Ilha dos Rollas, an island near St. Thomas's, on the west coast of Africa: the natives informed him that they had escaped from a vessel wrecked there many years ago; they were extremely wild, and had "a cry quite different to that of the domestic fowl," and their appearance was somewhat changed. Hence it is not a little doubtful, notwithstanding the statement of the natives, whether these birds really were fowls. That the fowl has become feral on several islands is certain. Mr. Fry, a very capable judge, informed Mr. Layard, in a letter, that the fowls which have run wild on Ascension "had nearly all got back to their primitive colours, red and black cocks, and smoky-grey hens." But unfortunately we do not know the colour of the poultry which were turned out. Fowls have become feral on the Nicobar Islands (Blyth in the 'Indian Field,' 1858, p. 62), and in the Ladrones (Anson's Voyage). Those found in the Pellew Islands (Crawfurd) are believed to be feral; and lastly, it is asserted that they have become feral in New Zealand, but whether this is correct I know not.

[393] Dr. Pickering, in his 'Races of Man,' 1850, p. 374, says that the head and neck of a fowl is carried in a Tribute-procession to Thoutmousis III. (1445 B.C.); but Mr. Birch of the British Museum doubts whether the figure can be identified as the head of a fowl. Some caution is necessary with reference to the absence of figures of the fowl on the ancient Egyptian monuments, on account of the strong and widely prevalent prejudice against this bird. I am informed by the Rev. S. Erhardt that on the east coast of Africa, from 4 deg. to 6 deg. south of the equator, most of the pagan tribes at the present day hold the fowl in aversion. The natives of the Pellew Islands would not eat the fowl, nor will the Indians in some parts of S. America. For the ancient history of the fowl, see also Volz, 'Beitrage zur Culturgeschichte,' 1852, s. 77; and Isid. Geoffroy St. Hilaire, 'Hist. Nat. Gen.,' tom. iii. p. 61. Mr. Crawfurd has given an admirable history of the fowl in his paper 'On the Relation of Domesticated Animals to Civilisation,' read before the Brit. Assoc. at Oxford in 1860, and since printed separately. I quote from him on the Greek poet Theognis, and on the Harpy Tomb described by Sir C. Fellowes.

[430] The 'Field,' May 11th, 1861. I have received communications to a similar effect from Messrs. Brent and Tegetmeier.

[431] It appears that I have not correctly designated the several groups of vertebrae, for a great authority, Mr. W. K. Parker ('Transact. Zoolog. Soc.,' vol. v. p. 198), specifies 16 cervical, 4 dorsal, 15 lumbar, and 6 caudal vertebrae in this genus. But I have used the same terms in all the following descriptions.

[432] Macgillivray, 'British Birds,' vol. i. p. 25.

[433] It may be well to explain how the calculation has been made for the third column. In G. bankiva the leg-bones are to the wing-bones as 86 : 54, or as (neglecting decimals) 100 : 62;—in Cochins as 311 : 162, or as 100 : 52;—in Dorkings as 557 : 248, or as 100 : 44; and so on for the other breeds. We thus get the series of 62, 52, 44 for the relative-weights of the wing-bones in G. bankiva, Cochins, Dorkings, &c. And now taking 100, instead of 62, for the weight of the wing-bones in G. bankiva, we get, by another rule of three, 83 as the weight of the wing-bones in Cochins; 70 in the Dorkings; and so on for the remainder of the third column in the table.

[434] Mr. Blyth (in 'Annals and Mag. of Nat. Hist.,' 2nd series, vol. i., 1848, p. 456) gives 31/4 lb. as the weight of a full-grown male G. bankiva; but from what I have seen of the skins and skeletons of various breeds, I cannot believe that my two specimens of G. bankiva could have weighed so much.

[435] The third column is calculated on the same principle as explained in the previous foot-note, p. 271.

[445] I have met with several statements on the fertility of the several breeds when crossed. Mr. Yarrell assured me that Call and common ducks are perfectly fertile together. I crossed Hook-billed and common ducks, and a Penguin and Labrador, and the crossed ducks were quite fertile, though they were not bred inter se, so that the experiment was not fully tried. Some half-bred Penguins and Labradors were again crossed with Penguins, and subsequently bred by me inter se, and they were extremely fertile.

But besides the improbability of a bird having long ago become extinct in these large and luxuriant islands, it appears (as we shall presently see) that the turkey degenerates in India, and this fact indicates that it was not aboriginally an inhabitant of the lowlands of the tropics.

AEgilops triticoides, is a hybrid between wheat and AE. ovata. The frequency with which these hybrids spontaneously arise, and the gradual manner in which the AE. triticoides becomes converted into true wheat, alone leave any doubt on the subject.

An eminent botanist, Prof. Decaisne, has lately expressed doubts on the subject from his own negative results, but these cannot be valued equally with positive results. On the other hand, M. Carriere has lately stated ('Gard. Chronicle,' 1865, p. 1154) that he took seed from a wild carrot, growing far from any cultivated land, and even in the first generation the roots of his seedlings differed in being spindle-shaped, longer, softer and less fibrous than those of the wild plant. From these seedlings he raised several distinct varieties.

Another high authority, Mr. Rivers, who has had such wide experience, strongly suspects ('Gardener's Chronicle,' 1863, p. 27) that peaches, if left to a state of nature, would in the course of time retrograde into thick-fleshed almonds.

[640] Whether this is the same variety as one lately mentioned ('Gard. Chron.' 1865, p. 1154) by M. Carriere under the name of Persica intermedia, I know not: this var. is said to be intermediate in nearly all its characters between the almond and peach; it produces during successive years very different kinds of fruit.

[697] Mr. Lowe states in his 'Flora of Madeira' (quoted in 'Gard. Chron.,' 1862, p. 215) that the P. malus, with its nearly sessile fruit, ranges farther south than the long-stalked P. acerba, which is entirely absent in Madeira, the Canaries, and apparently in Portugal. This fact supports the belief that these two forms deserve to be called species. But the characters separating them are of slight importance, and of a kind known to vary in other cultivated fruit-trees.

[714] Most of the largest cultivated strawberries are the descendants of F. grandiflora or Chiloensis, and I have seen no account of these forms in their wild state. Methuen's Scarlet (Downing, 'Fruits,' p. 527) has "immense fruit of the largest size," and belongs to the section descended from F. Virginiana; and the fruit of this species, as I hear from Prof. A. Gray, is only a little larger than that of F. vesca, or our common wood strawberry.

[896] M. Carriere has lately described, in the 'Revue Horticole' (Dec. 1, 1866, p. 457), an extraordinary case. He twice inserted grafts of the Aria vestita on thorn-trees (epines) growing in pots; and the grafts, as they grew, produced shoots with bark, buds, leaves, petioles, petals, and flower-stalks all widely different from those of the Aria. The grafted shoots were also much hardier, and flowered earlier, than those on the ungrafted Aria.

[906] This hybrid has never been described. It is exactly intermediate in foliage, time of flowering, dark striae at the base of the standard petal, hairiness of the ovarium, and in almost every other character, between C. laburnum and alpinus; but it approaches the former species more nearly in colour, and exceeds it in the length of the racemes. We have before seen that 20.3 per cent. of its pollen-grains are ill-formed and worthless. My plant, though growing not above thirty or forty yards from both parent-species, during some seasons yielded no good seeds; but in 1866 it was unusually fertile, and its long racemes produced from one to occasionally even four pods. Many of the pods contained no good seeds, but generally they contained a single apparently good seed, sometimes two, and in one case three seeds. Some of the seeds germinated.

[939] It may be worth while to call attention to the several means by which flowers and fruit become striped or mottled. Firstly, by the direct action of the pollen of another variety or species, as with the above-given cases of oranges and maize. Secondly, in crosses of the first generation, when the colours of the two parents do not readily unite, as in the cases of Mirabilis and Dianthus given a few pages back. Thirdly, in crossed plants of a subsequent generation, by reversion, through either bud or seminal generation. Fourthly, by reversion to a character not originally gained by a cross, but which had long been lost, as with white-flowered varieties, which we shall hereafter see often become striped with some other colour. Lastly, there are cases, as when peaches are produced with a half or quarter of the fruit like a nectarine, in which the change is apparently due to mere variation, through either bud or seminal generation.
