Summary. 
1. The close association existing between the weeds of arable land and 
the soils on which they grow holds good for ‘ drift ’ soils as well as for those 
derived from the underlying rocks. As before, the texture of the soil was 
more important than its derivation in determining the weed flora. 
1. It was again found that this association may be either — 
(a) Ge 7 ieral. When a weed is always associated with one type 
of soil in every district. 
(b) Local. When a weed associated with a soil in one district 
is absent from or rare on similar land in other places.
