Lucerne. It is likely to be destroyed by the pareful farmer. As 

 soon as the slender vine from the seed gets fast to the stem of a 

 plant, the root of the dodder perishes. It takes nourishment from 

 the Lucerne. The seeds are very small and spherical. Sulphate 

 of iron (green vitriol), one pound to the gallon, sprinkled on

 Lucerne. A sieve of the jiroper size will remove the seeds. I'he 

 seeds will remain alive in the soil for some years. A similar cus- 

 cuta is parasitic on red clover.

 often a very troublesome weed. The roots run deep and spread 

 in every direction. The seeds are carried by the wind. 



ChoiopodiHvi album, L. (Pigweed, Lamb's Quarters.) This

 troublesome in pastures and meadows, but are mentioned here 

 because the seeds are sometimes met with in seeds of grasses and 

 clovers. 



The seeds are lenticular, black, and glossy, find ;ire much like 

 those of Amar an tints. 



Another plant, or rather several plants of the genus Amaran- 

 ilius, are often spoken of as pigweeds. They are not very likely
