Injuries from Weeds. ly 



evident that grain entirely free from the 

 seeds of weeds always commands, even in 

 the ordinary market, a higher price than 

 grain that is unclean. When grain con- 

 taining weed seeds is put on sale for sow- 

 ing, the depreciation in value is much 

 greater relatively. The seedsman cannot 

 afford to pay good prices for seed grain of 

 any kind if he must spend much time and 

 labor upon it in removing the seeds of nox- 

 ious weeds. Oftentimes it is found impos- 

 sible to completely separate weed seeds from 

 the grain in which they ^re found by any 

 other process than that ' of hand-picking. 

 With the farmer, in preparing a crop of 

 any kind for market, this would be simply 

 impossible. All kinds of grain should be 

 considered as unfit for seed, however, so 

 long as any seeds of noxious weeds are 

 found in it. 



The difficulty in removing the seeds of 

 weeds from those of grasses and clovers is 

 much greater than in removing them from 

 the small grains, owing to the greater rela- 

 tive uniformity in the size of the weed seeds 

 and the seeds of the grasses. The labor of 

 the cleaning process, therefore, is also rel- 

 atively greater, and in very many instances
