The foregoing lists may be usefully compared with the corre- 
sponding lists given by Jawes, Gilbert, and Masters in the clas-

carried out upon grass-land, probably some centuries old, at 
Rothamsted Park, Hertfordshire; the land is described as 8

drained. Although the plots of meadow-land at Rothamsted 
were subjected to twenty continuously different kinds of manuring, 
a comparison of the entire flora there with that at North Charford
