Eradication of the Ritssiaji Thistle. 201 



their stead, such as cultivated crops or tlie 

 tame grasses. 



2. Spudding. When the weed plants 

 are not numerous they may be destroyed 

 by cutting them off with the spud below 

 the crown any time before the seeds are 

 matured, but the work will- be much more 

 easily done at an early rather than at a 

 late stage of growth. Along fence bor- 

 ders and in waste-places they may also be 

 thus destroyed. 



J. G voicing tzi'o cultivated crops. If 

 two cultivated crops are grown in succes- 

 sion on the same land, and if at the same 

 time proper cultivation is given to them, 

 the weeds will be all destroyed. 



4. Growing forage crops and pasturing 

 them zuith sheep. The Russian thistle may 

 be easily destroyed by growing certain for- 

 age crops and pasturing them wnth sheep 

 for two years in succession. Winter rye 

 should be given a prominent place among 

 these crops where it can be successfully 

 grown. The rye may be followed about 

 the end of May with corn, sorghum, millet 

 or rape. Sheep seem to relish the thistles 

 when young and tender.
