IN consequence of a more perfect acquaintance with the nature of soils, and with the operation of the various sub- stances that are made use of in the business of cultivation, as well as from additional experiments and more close ap- plications of the principles of other sciences, numerous alterations and improvements have been introduced in the different branches of the art of husbandry, and a great variety of new facts, opinions, and conclusions have been brought to the attention of the agricultor. These im- provements have, however, been hitherto of little use, from their being scattered and dispersed through innu- merable volumes, without method or arrangement to render

their connection, or dependence, clear and intelligible.

It has been the object of the present work not merely to reduce such detached facts imto better order, but at the same time to bring the practical details aad conclusions into a more intimate connexion with the principles on watch
