The object of the following work, on the History, Breeding, Management, Diseases, &c., of Domestic Animals, is to afford the Stock-breeder and Grazier a connected view of the entire subject in which he has so deep an interest. The writer has endeavored to compress within the limited space assumed as necessary to secure a general circulation and perusal, such principles and practice, and give to each that relative prominence, which it becomes the practical man to observe, to realize the greatest amount of value for the labor and capital devoted to his pursuits.

Their history is essential, as it shows their introduction into the United States, their progress during the various stages of their improvement, and the comparative value of the improved and ordinary breeds. A knowledge of the best mode of breeding and management is of still higher importance. The first will enable the breeder to preserve the high character of the animals in his hands, or perhaps still farther to advance them; while proper management and feeding will prevent that deterioration and loss from disease, which frequently subtract so much from his profits.

A larger space has been purposely devoted to the last topics, in preference to the subject of diseases, as prevention is not only less troublesome than cure, but much more economical. Feeding and management, after breeding, are really the important objects in view to the Stock-breeder and Grazier, for if these be judiciously attended to, disease among the herds will rarely be known.

The subject of animal diseases is complicated and little understood; and to be properly comprehended, requires years close, intelligent study, under every advantage for obtaining the necessary information. Nearly every disorder assumes various shades of difference, and to remove it effectually a corresponding change of treatment is required. How absurd then the idea, that a compilation of formal remedies, administered by an unskilful or inexperienced manager, will be of material service in rescuing his herds or flocks from the ravages of disease. All that can consistently be done, is to give a few simple remedies for the most common and well-known ailments, and leave to nature or a professional farrier, such as are more complex or unusual.

This work (with many subsequent and important additions) constitutes a small part of the "Compend of American Agriculture," the favorable reception of which, though but recently given to the public, has induced the writer to offer this important division of the subject in its present detached form.
