THE EFFECTS OF DOMESTICATION. 



If we contrast Northumberland with Aberdeenshire, Lincoln 

 with Perth, Kent with Sutherlandshire, we shall at once see 

 the immense difference in productive power between the 

 fertile English soil and the barren uplands of the North of 

 Scotland. 



Still, as already shown, Scotland is far ahead of England 

 as a sheep-breeding country, and this conclusion is not 

 falsified by the few instances just given in which the moun- 

 tains of Aberdeen, Perth, and Sutherland are contrasted with 

 the richer soils of Northumberland, Lincoln, and Kent.
