The following is a brief summary of the more important points which our investigations so far appear to have given us:—

1. That white clover and ryegrass form by far the greater part of the herbage on the best grazing lands—both old and recent in the English Midlands—and that the next most abundant species on these pastures are usually crested dogstail, florin (A. stolonifera), and rough-stalked meadow grass.

2. That the herbage of the inferior types of grass land in the same district consists very largely of bent grass (A. vulgaris) and various weeds, while white clover and ryegrass are present in comparatively small quantities.
