But crossing may be done in a way to develop good qualities, and these may afterward be fixed by careful selection and inbreeding of offspring. This subject of breeding is one of great importance, and yet little understood. Many things pertaining to it are yet to be settled, though great progress has been made during the last few years, and public attention is being drawn to it as it never was before. It will be found that man can become master of the situation, and may, by observing certain fundamental conditions and varying only the details, breed domestic animals of almost any form, disposition, and quality, that he may desire. CARE AND KEEP. Better care and keep, however, are the key notes to improvement. Higher conditions and better surroundings lead to improvements which may be developed into fixed traits by proper selection and coupling, provided the improved environment is maintained. The status can be maintained only by maintaining the conditions. This is what we mean by care. Under this head, we include all that pertains to the health and comfort of the animal. Judicious care is of prime importance not only in breeding but in securing the best results in dairy products. Proper food and drink and enough of it, with shelter, kind treatment, regularity and the most thorough system, must be provided, or corresponding failure, for any and all abuse, neglect or mistake, is sure to follow. FEEDING STOCK. The question of feeding stock is yearly rising into greater prominence and importance. Formerly, it was thought that anybody who could throw out coarse fodder and hay to cattle knew enough for all practical purposes about feeding, and that any sort of a shelter, or no shelter, if the animal survived, was sufficient. Better ideas are beginning to prevail. Few men now think they know all that can be learned about feeding stock, and those who know the most are the most anxious to learn. A thorough knowledge of feeding requires a knowledge of physiology and biology, with the chemical composition and nutritive qualities of the different kinds of food. Added to this must be the practical knowledge gained by observation of the effects of the different foods on different animals under various conditions. And when all is known that can be, there will still be room left for the exercise of the best judgment of the feeder as to the conditions and requirements of the animal fed, and as to the quality of the foods available and the quantity and proportions of each. CARBONACEOUS AND NITROGENOUS FOODS.
