The crag is cut into and exposed by the rivers of the Broads 
District, and most of the high land fringing the valleys of 
the Bure and Yare is formed of crag. The rock weathers 
down to a light sandy soil, containing many small pebbles 
but no large stones. The chemical analyses show a very 
low percentage of phosphorus, but a relatively high one of 
Table X.
