generally repayed by the first two or three crops which succeed each improvement. What more, then, can be required? The expense is repaid--the land is, to a certain extent, permanently improved--no risk of loss has been incurred, and there still remains to the improving farmer--improving his own circumstances, as well as the quality of his land, by his prudent and skilful measures--there still remains the deeper ploughing, by which he can gradually bring new soil to the surface, as he sees it mellow, and become wholesome, under the joint influences which the drain and the subsoil-plough have brought to bear upon it. There can, therefore, it is clear, be no universal rule for the use of the two valuable instruments in question, as each has its own defined sphere of action. This, we think, is the common-sense view of the case. But if any one insists upon having a universal rule which shall save him from thinking or observing for himself in all cases, then we should say--_in all cases subsoil, because it is the safer_. With this subject the first volume of _The Book of the Farm_ is brought to a close; but winter still continues, and in other winter-work of scarcely less importance the young farmer has still to be instructed. We have hitherto said nothing of the more expensive and beautiful embellishments of the book, because the most interesting of them are portraits of celebrated short-horns, working horses, sheep, and pigs--a subject of which the author begins to treat only at the commencement of the second volume. The feeding of stock is one of those parts of the winter's labours, in improving husbandry, upon which not only the immediate profit of the farmer, but the ultimate fertility of his land, in a great measure depends. The choice of his stock, and the best mode of treating and tending them, therefore, are subjects of the greatest consequence to the young farmer. In the choice of his stock he will be aided at once by the clear descriptions, and by the portraits so beautifully executed by Landseer and Sheriff, by which the letterpress is accompanied. In the subsequent treatment of them, and in the mode by which they may be most profitably, most quickly, or most economically fed _in the winter season_, he will be fully instructed in the succeeding chapters of the book.
