or stables.- It is often remarked that ''the pastures are robbed to 

 keep up the fertiUty of the plowed fields." 



Perhaps one of the greatest sources of loss of fertility from pasture 

 soils results from the poor location of the shade trees and brush. 

 These should always be set on the higher portions of the field, and not 

 along the banks of running streams, as so often is the case. (Fig. 11.) 

 With good grass, the animals do not graze more than one-third of the

time ; the rest of the time is spent lying down or standing in the shade 

 fighting flies. Hence, much of the manure that is made does not get 

 back directly on the land that produced the grass. If the manure 

 produced while the animals are not grazing is deposited on the tops 

 of the hills, its beneficial effects on the grass may be noted for several 

 rods down the hillsides. It is easy to believe that if one-half to two- 

 thirds of the manure is lost from pasture fields and none is added, the 

 crops must gradually deteriorate.
