130 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 re-seeded. Red clover is 

 usually followed by a grain crop before clover is again 

 grown. 



6. Other Types of Clover 



None of the other clovers compare with red clover 

 in their general value to the northern and central farms. 

 Yet a few other types are of great importance in other 

 sections. 



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. 

 It makes an excellent pasture grass, and is also often used 

 in lawn mixtures. 



Alsike clover. Alsike clover is named from a town 

 in Sweden, where it is said to have originated. It resem- 

 bles red clover but is of a finer, more delicate type, and 

 therefore does not yield so well. While red clover will 

 produce two crops each season, alsike clover will grow 

 but one. This clover is especially suited to wet heavy soil
