Page 15 - Fancying" provides the chief interest in life for thousands of persons in this country. It is an occupation with which the scientific naturalist should have more sympathy than he has commonly evinced. If the scientific world had kept in touch with the operations of the " fancy " much nonsense which has passed into scientific orthodoxy would never have been written. The study of Mendelian phenomena will do something to bring about a fruitful interchange of experience. But for the " fancy " our work...
Page 29 - A family of any variety of fowls bred in line by descent by one fancier, or a successor, during a number of years, that has acquired individual characteristics which distinguish it more or less from other strains or specimens of the same variety.
Page 71 - Narrow bars extend across the feathers from the top of the head to the end of the tail and broaden as they reach the extremities.
Page 16 - ... breeding shews that, on the average, one half of the offspring from a pen of blue Andalusians come blue, one quarter black, and one quarter white. These proportions at once suggest that the blues are heterozygotes. For we have already seen that the breeding of heterozygotes together results in one half of the total offspring coming heterozygotes. If this is so, it follows that the blacks and splashed whites are by nature homozygous, and consequently ought to breed true. Experiment has shewn that...
Page xv - ... slightly glossed with purplish blue; greater coverts, black, more or less mixed or margined on the outer web with dark chestnut; feathers at the base of the naked throat, rich glossy violet; chest, breast, and sides, like the lower part of the mantle; feathers of the belly, chestnut mottled or tipped with purplish blue. Comb, wattles, and naked skin about the head, yellowish or purplish red, the former with a large oval yellow spot on the middle of the posterior half; bill, yellow; feet and legs,...
Page 17 - Further, we should be led to expect heterozygous offspring from a union of two homozygotes. Here again the experimental results accord with the theory. When splashed black and white are bred together all the offspring without exception are blue. Paradoxical as it may sound, the mating of the black and white wasters gives a proportion of blue Andalusians twice as great as the mating of blue with blue. The black and the white splashed are really the pure breeds. The pure blue Andalusian is, and from...
Page 49 - In these the requirements arc to confine the gray and the white to the parts to which they belong, to have them properly distributed, to maintain the beautiful penciling of the female, and to secure the brilliant glistening black in the breast and body plumage of the males and a clean, clear top color. 39. Influence of Color of Under Plumage. The downy portion of the plumage, which is not visible when the plumage of a fowl is in its natural position is called the under plumage. The shade of color...

Page 54 - ... 2 Metal bands for attaching to the shanks are a satisfactory method of marking fowls, and permit of sufficient variations. Several forms of aluminum bands are shown in Fig. 9. The small band shown in (a) is suitable for placing around the shank of a chick, and later, when the shank grows too large for this band, it may be removed and fastened through the web of the wing. The band shown in (b) is used for chicks also, but is rather too wide to insert in the web of the wing.
Page 50 - The next step is to transfer the fowl to the tvib of lukewarm water and thoroughly rinse it. All of the remaining dirt and soap should be removed in this second water. The fowl should be lifted out of the lukewarm water and held for a few moments to allow the water to drain from the feathers. Then it should be immersed several times in the third tub containing the cold water. This will serve to harden the fowl and prevent it from...
