. The call of the hen; or, The science of selecting and breeding poultry for egg-production. Poultry. THE CALL OF THE HEN. 79 take it for granted that the reader has no method of selecting the good from the poor layers, except, perhaps, the "Walter Hogan System" or some of its pirated forms that are now used extensively in all parts of the civilized world, and which is based on the theory that the value of a hen as an egg-producer depends on the relative distance apart of her pelvic bones and the thinness of same. We will suppose the reader has .300 hens; one lot are about a year and four months old, another lot are about two years and four months old, and another lot are about three years and four months old. Each lot has been kept in separate yards, so there can be no mistake in regard to their ages, or they have been toe-punched or otherwise marked. We notice more or less feathers lying around the yard, thus indicating the season of the year when moulting is near at hand. Everything else being equal, the poorest hen moults first, and if she is a very poor layer, she will stop laying when she begins to moult and will not lay again until the crows lay in the spring. We consider it is about time to cull out the poor layers and send them to Fig. 42—Showing thumb \i of an inch behind forefinger; indicating hen has pre- potency large. (See Skull No. 1, Fig. 35.).
