This shows that a plain rotation is itself capable of increasing yield, but that a greater increase is to be expected by a combination of rotation and manuring. The iirst rotation-farming to gain wide attention in North America seems to have been the so-called Norfolk system. This was chiefly a four-crop rotation employed on the light lands of Norfolk, England, and which had grown up during a long course of years. A century and more ago this system was explained by writers and thereby became widely known, the more so because at that time the American agricultural literature was drawn chiefly from English sources. An account of " the Improvements made in the County of Norfolk" comprised the larger part of Jared Eliot's "Fourth Essay upon Field Husbandry, " published at Killingworth, Connecticut, in 1753. The exact rotation itself—comprising roots, barley, clover, wheat, in various combinations—was of less impor- tance to the American colonies than the fact that attention was called to the value of rotation-farming in general. At the same epoch another system of farming practice was also coming in from English sources. This was the clean- tillage system introduced by the epoch-making experiments of Jethro Tull. Between the discussions of the Tull " new husbandry" and the Norfolk rotations, agricultural practices were challenged and overhauled in the new country. One of the early explanations of the good-
