Note 14 — DISCOURSE.
Reading edition
The Trench-Plough of Mr. Ducket's invention was so admirably contrived as completely to bury whatever was intended to be turned in. Mr. Young says he saw him turn down a crop of rye, six feet high, so that not an atom was left visible; and yet the depth did not exceed eight inches. Trench ploughing has sometimes been effected in this country by a second plough following in the same furrow after the first, and going a few inches deeper.
