FOX. Down, May 7th [1855].
My dear Fox,
My correspondence has cost you a deal of trouble, though this note will not. I found yours on my return home on Saturday after a week's work in London. Whilst there I saw Yarrell, who told me he had carefully examined all points in the Call Duck, and did not feel any doubt about it being specifically identical, and that it had crossed freely with common varieties in St. James's Park. I should therefore be very glad for a seven-days' duckling and for one of the old birds, should one ever die a natural death. Yarrell told me that Sabine had collected forty varieties of the common duck!...Well, to return to business; nobody, I am sure, could fix better for me than you the characteristic age of little chickens; with respect to skeletons, I have feared it would be impossible to make them, but I suppose I shall be able to measure limbs, etc., by feeling the joints. What you say about old cocks just confirms what I thought, and I will make my skeletons of old cocks. Should an old wild turkey ever die, please remember me; I do not care for a baby turkey, nor for a mastiff. Very many thanks for your offer. I have puppies of bull-dogs and greyhound in salt, and I have had cart-horse and race-horse young colts carefully measured. Whether I shall do any good I doubt. I am getting out of my depth.
Most truly yours, C. DARWIN.
[An extract from a letter to Mr. Fox may find a place here, though of a later date, viz. July, 1855:
"Many thanks for the seven days' old white Dorking, and for the other promised ones. I am getting quite a 'chamber of horrors,' I appreciate your kindness even more than before; for I have done the black deed and murdered an angelic little fantail and pouter at ten days old. I tried chloroform and ether for the first, and though evidently a perfectly easy death, it was prolonged; and for the second I tried putting lumps of cyanide of potassium in a very large damp bottle, half an hour before putting in the pigeon, and the prussic acid gas thus generated was very quickly fatal."
A letter to Mr. Fox (May 23rd, 1855) gives the first mention of my father's laborious piece of work on the breeding of pigeons:
"I write now to say that I have been looking at some of our mongrel chickens, and I should say ONE WEEK OLD would do very well. The chief points which I am, and have been for years, very curious about, is to ascertain whether the YOUNG of our domestic breeds differ as much from each other as do their parents, and I have no faith in anything short of actual measurement and the Rule of Three. I hope and believe I am not giving so much trouble without a motive of sufficient worth. I have got my fantails and pouters (choice birds, I hope, as I paid 20 shillings for each pair from Baily) in a grand cage and pigeon-house, and they are a decided amusement to me, and delight to H."
In the course of my father's pigeon-fancying enterprise he necessarily became acquainted with breeders, and was fond of relating his experiences as a member of the Columbarian and Philoperistera Clubs, where he met the purest enthusiasts of the "fancy," and learnt much of the mysteries of their art. In writing to Mr. Huxley some years afterwards, he quotes from a book on 'Pigeons' by Mr. J. Eaton, in illustration of the "extreme attention and close observation" necessary to be a good fancier.
"In his [Mr. Eaton's] treatise, devoted to the Almond Tumbler ALONE, which is a sub-variety of the short-faced variety, which is a variety of the Tumbler, as that is of the Rock-pigeon, Mr. Eaton says: 'There are some of the young fanciers who are over-covetous, who go for all the five properties at once [i.e., the five characteristic points which are mainly attended to,--C.D.], they have their reward by getting nothing.' In short, it is almost beyond the human intellect to attend to ALL the excellencies of the Almond Tumbler!
"To be a good breeder, and to succeed in improving any breed, beyond everything enthusiasm is required.
