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!
