[[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.
