Rotation at first of three-shifts, viz.: 1 corn, 2 wheat on the richer half, 3 at rest, and after 1814 not grazed. This changed gradually to 4 shifts (by 1823) of 1 corn, 2 wheat, 3 and 4 at rest. 1820, began to fallow for wheat, in part and only in some years. In 1826 or 1827 began to sow the wheat fields generally in clover, and about 1835, to fallow a part (say one- fourth to one-third) of each clover field for wheat the year preceding the crop of corn. This changed in 1840 to a five-shift r...otation, one-fifth of the arable land being in corn, two-fifths in wheat (and oats), and two-fifths in clover (or Avceds), or other green or manuring crops. The crops of wheat for first six years (1813 to 1818) raised on the richer parts of each shift, making not much more than one-half the land only; the remainder being then much too poor to be sown. As these poorest parts were marled, all were sown in wheat, in their turn. Therefore, the earlier average products of wheat per acre as stated, were for the richer part of the land, while since 1822 the average is for the worst as well as the best land of each shift.
