from each other, in old furrows of the ground, ahd about five inches deep; the ſod, when cut out by the plough, was of a wedge-like form, and turned out by if upon the ridges of the tand, entirely ſeparated from the drain or gutter. Theſe ſods were afterwards divided acroſs, by a ſpade, into lengths of abóut two feet cach, then toſſed by a pitchfork into a cart, and placed in a heap in the field, along with ſtrata of quick-lime in 2 pow- dery fate: the whole maſs was reduced toa compoît by the froit during the winter; and in the following ſpring was Jaid upon the ſurface of the land, and formed an excellent top dreffing.

The water from the ſmall drains was dir-@ed into larger drains, made by lowering the ſhares of the plough to the depth of nine or more inches. Little or no loſs of land aroſe from the ſmall drains, as natural graſſes were produced therein, early in the ſpring. It will be highly advantageous to repeat the ope- ration every winter: it is eafily and expeditiouſly performed; and no perſon, without an a@ual experiment of the fat, can form a ſufficient judgment of the great bencfit ariſing to vegeta- tion by the removal of cold ſtagnant water, during the winter, from land of every deſcription.
