which will not readily grow cuUivated 

 crops. 



Another way is to sow the rye in 

 August, and then pasture it both autumn 

 and spring, before the ground is plowed 

 for the following crop. This mode is not 

 quite so effective as the one just described, 

 inasmuch as the rye when pastured does 

 not so effectually weaken the thistles by 

 smothering them as when it is grown for 

 fodder or for the silo. 



On the Ontario Agricultural College 

 Experiment Station farm at Guelph, this- 

 tle-infested fields have been so effectively 

 cleaned by the mode of treatment recom- 

 mended here that in the following year one 

 person could go over twenty acres in from 

 ten to fifteen hours, and remove with a 

 spud all the noxious weeds found in the 

 grain crop which followed the rape. 



4. Breaking up pasture land or meadoiv 

 and sowing to fall zvlieat and clover. Plow 

 pasture land in June, or plow land from 

 which a crop of hay has been removed, as 

 soon as possible after the crop has been 

 harvested. Work the plowed ground upon 

 the surface, so that all thistles will be kept 

 under until the time arrives for sowing
