are to be attributed. Moisture is absolutely necessary to vegetation. The richest land without it is entirely unproductive. Upon this principle it is decidedly injurious to deprive land of its small stones. They not only cause it to retain moisture; but, by keeping it light, enable it to receive much rain. They also render the earth warm, and admit into it the necessary quantity of air. By depriving land of its stones the earth falls into a solid mass, and the consequence is, that it imbibes but a small portion of rain. The stones of our fields should be rolled in as soon as the grain is sowed. On the surface they will be useless, and very troublesome.
I have suggested, that we cultivate too much land to render agriculture profitable. I speak in relation to the means which we employ for fertilizing our land. Much may be done without the aid of manure; but the use of this article is the most ready and efficient mode of rendering the cultivation of the earth profitable. Instead, however, of increasing this article by compost, we misapply that which is incident to our farms. By spreading a small quantity of manure upon a large piece of poor land, it is almost entirely lost; in as much as it remains in an inactive state. There is not a sufficient quantity to give an impetus to the cold and barren earth with which it is mixed. This is one great cause of poor crops; and the great surface over which the labour of the husbandman is spread is the principal ground of the excessive labour of which he complains. Should the farmer plough {46} only as much land as he could highly manure, his labour would be comparatively small, his crops great, and his land constantly improving. By this mode of proceeding the crops would not exhaust the land; and the quantity of manure upon it, beyond what is necessary to the production of the crops, would, by its fermentation, fertilize and render
