months, we did not pay as much attention as we should have liked to 

 the question of the changes in the coraposition^of the grass-associations 

 as altitude increases. But the selected list given ahove may be 

 compared with the following flora of a typical upland pasture : —

In another case an upland meadow, of which portion was undis- 

 turbed, and portion but recently broken up and sown with grass, gave 

 both a useful total list and an indication of the changes of flora 

 induced by such a disturbance. See page 149 (C = common, 

 F = frequent, R = rare, x = present). 



A division of the cultivated land into a portion showing wheat 

 cultivation, and a second where oats is the chief crop, as has been 

 done on most of the English and Scottish vegetation maps, was not 

 found to be possible in our area, since wheat is so little cultivated.
