174 AGRICULTURE 



mowing the clover soon after it starts will do much to reduce 

 the danger. 



Clover has at least one enemy that works after the 

 crop is stacked or mowed ; this is the clover-hay worm*. It 

 usually works in the bottom of the stack or mow, eating 

 the softer portions of the plant, but also damaging the 

 feeding qualities of the hay by its excrement and a web 

 that it leaves. Salting the hay near the bottom of the 

 stack or mow will do much toward stopping the work of 

 this pest. 



While the botanists tell us that red clover is a perennial, 

 it is seldom able to maintain a stand for more than three 

 or four years, when it must be reseeded. Red clover is 

 usually followed by a grain crop before clover is again 

 grown. 



6. Other Types of Clover 



Crimson clover. This clover and its cultural methods 

 are similar to those of red clover, but it differs from the oth- 

 er clovers in being an annual. It is a relatively new crop, 

 having recently been brought to this country from Europe. 

 It is grown chiefly in the southeastern part of the United 

 States, where it assumes the same importance that red 

 clover has farther north. Crimson clover does not demand 

 so rich a soil as red clover or alfalfa. It is of great im- 

 portance in the east, southeast and southwest of the United 

 States. 



White clover. White clover is well known over most 

 of the red clover region. It differs in its manner of growth 

 from red clover, being of a creeping habit, and therefore 

 not well adapted to use as a hay crop. White clover is 

 very hardy, and will often work its way into a pasture with- 

 out seeding, the seeds being carried by winds and the birds.
