[49] Unfortunately, the figures for the year 1299-1300 reveal an error which makes it impossible to use the test of the representativeness of Witney in a third season with accuracy. The acreage planted is obviously understated, and it is possible to make only a rough estimate of the correct acreage. The acceptance of the area given by Gras (82 acres) results in the conclusion that 22 bushels per acre was reaped. The suspicion that this result must be incorrect is confirmed when it is found, also, that 68-1/4 quarters of seed were sown--an amount sufficient for 270 acres at the average rate of 2 bushels per acre, or for 220 acres at the rate of 2-1/2 bushels per acre, which Ballard gives as the rate usual at Witney. (Levett and Ballard, _op. cit._, p. 192.) In 1277 the acreage sown with wheat at Witney was 180 acres, and in 1278, 191. (_Ibid._, p. 190.) If 3 bushels per acre were sown in 1299, the area in this year also was 180 acres. If these estimates are used instead of the figure 82, as indicating the correct acreage, the yield for the year is found to be between 7 and 10 bushels per acre, in a season in which the average yield for the whole group of manors was 9 bushels per acre. The figures at Witney in the three seasons where a comparison with the general average for the group is possible deviate from it within limits narrow enough to indicate that conditions at Witney were roughly typical.

Corn Market_ (Cambridge, 1915), appendix A. [54] Gras gives 1.35 quarters as the acre produce, or nearly 11 bushels. This figure is incorrect, as it is derived by dividing the total produce of 42 manors by the total acreage planted on only 38 manors. The produce of the four manors on which the acreage planted is unknown amounts to nearly 750 quarters, a large item in a total of only 4527 quarters for the whole group of manors. The ratio of produce to seed, however, is independent of the number of acres planted, and these four manors are included in the computation of this figure. [55] Gras, _op. cit._, appendix A. These figures are given only for the manors for which the acreage planted in both periods is known--25 in the case of wheat, 4 in the case of the other grains.
