From an attentive examination of the pages of this book, I have come to the conclusion that it is one of the best works extant, on the principles of scientific agriculture, and the best compendium of our most recent knowledge of the nature of manures and their adaptation to particular soils and crops. It cannot be expected that a single volume could possibly contain the whole sum of chemical knowledge applicable to the science of agriculture; but, on looking over the closely-printed and compact tables of analyses, and the abundant formulas, which this publication contains, I could not fail to be surprised at the industry manifested in preparing it. I was also gratified to find it so well adapted to the American system of husbandry, and so practical, in its character. Its copious and accurate index adds not a little to its value. I shall certainly recommend it to my agricultural friends as a very useful book, and one necessary to every scientific farmer. I am, respectfully, your ob't servant, CHARLES T. JACKSON, State Assayist, &c., &c. To C. M. SAXTON, Esq., New York. * * * * * THE AMERICAN FARM BOOK, OR COMPEND OF AMERICAN AGRICULTURE CONTAINING A CONCISE AND PLAINLY-WRITTEN EXPOSITION OF DUTIES PERTAINING TO THE CULTIVATION OF THE EARTH, THE MANAGEMENT OF THE FARM, &C., &C., ON PRACTICAL SCIENTIFIC PRINCIPLES. BY R. L.

These branches of knowledge are given as applicable to agricultural pursuits, and when properly understood will essentially aid and assist the farmer. In fact, a knowledge of these sciences is a sure key to wealth for any agriculturist. It gives the modes of preparation, and the effects of all kinds of manures; the origin, texture, divisions, and description of every variety of soil; the economy of sowing, reaping, and mowing, irrigation, and draining; cultivation of the grasses, clovers, grains, and roots; _Southern_ and miscellaneous products, as cotton, hemp, flax, the sugar cane, rice, tobacco, hops, madder, woad, &c.; the rearing of fruit--apples, pears, peaches, plums, grapes, &c.; farm buildings, hedges, &c.; with the best methods of planting, cultivating, and preparation for market.
