66 Weeds. 



Perennials, as their name implies, live 

 from year to year. Of perennial weeds 

 there are two classes, viz., the perennial 

 with an ordinary root, and the perennial 

 with a creeping root-stock. The perennial 

 weed with an ordinary root-stock, or, as we 

 may call it for our purpose, the ovdinavy 

 perennial, is reproduced from seed only. 

 The ox-eye daisy is a common example of 

 this sort of weed, and the plantain is 

 another, while alfalfa is a perenniaL field 

 crop. The creeping perennial, as we may 

 call it, is not only reproduced from seed, 

 but is also propagated by means of its hor- 

 izontal root-stocks, which run, or "creep," 

 through the soil in various directions from 

 the parent stem. These creeping root-stocks 

 are furnished with many latent buds, each 

 one of wdiich, under conditions favorable ta 

 vigorous growth, is capable of sending up 

 a fresh plant to the surface. It follows, 

 then, that the cultivation which does not 

 weaken and destroy creeping perennials 

 necessarily favors their increase, inasmuch 

 as a soil that has been recently stirred is 

 more easily penetrated by the creeping root- 

 stocks than one that has not been so stirred, 

 and has become more compact. Whenever
