 wheat, pats and barley, goes to the feeding of the humari 

 population and is lost to the animal inhabitants. This loss

 of uncultivated land. The full height of the columns represents the average numbers of 

 domestic animals on 1000 acres in Linlithgovv district (highly cultivated); the black 

 portions those in the same area of Ardnamurchan (almost uncultivated) (see text). The 

 lined portions of columns therefore indicate roughly the increase in numbers due to culti-
