Those who have attended to the subject well know, that the profitable management of live-stock is by far the most difficult branch of farming, as it is here that improvement is peculiarly tardy; and from this we might infer that authors would endeavour so to arrange and simplify their treatises as to enable every one to obtain the bearings of the study at the smallest possible expense and trouble. Such, however, is not the case. Many would appear to have done their best so to dilute and mystify the little which is known about the matter, that it is nearly impossible for any one, not gifted with more than ordinary power of application, to arrive at any thing like just conclusions. To avoid this error has been my object in the following pages. Such points only as are of real importance have been noticed; every thing having been rejected which could not admit of a practical application.
