seed on these pastures, because the acreage is so large, and 

 it is often difficult to obtain seed of the native grasses which

LABORATORY AND FIELD EXERCISES 



1. Visits to pastures in the neighborhood, with careful studies of the 

 plants of which they are composed, the prevalence of weeds, and such 

 other points as appear to be important, may be made with profit. The 

 best time to make these studies is late in the spring or early in the fall. 



2. Make parallel lists of as many things as you can think of 

 that contribute to a good pasture and what things should be avoided. 

 In a third column list the ways in which good pastui'e is useful.
