/S Weeds. 



relatively very large ; hence the opportu- 

 nity to destroy these weed seeds, when they 

 are thus collected, should by no nieans be 

 neglected. 



7. Grow cultivated crops. Wherever it 

 is desired to subdue noxious weeds wholly, 

 cultivated crops should be grown to the 

 greatest extent that is practicable. The 

 reasons are obvious. The cultivation of 

 these crops gives opportunity, at almost 

 every period of the growing season, for 

 the combating of almost every form 

 of weed life. The working of the soil 

 necessary for the production of good 

 crops not only destroys, from time to 

 time, the weeds that are growing in them, 

 but it also stimulates the germination of the 

 weed seeds lying in the soil, so that they, 

 too, grow up and are destroyed ; and in this 

 way it greatly reduces their numbers in a 

 single season. Pvlany farmers cling to the 

 opinion that, in the fight with weeds, cul- 

 tivated crops are not very helpful. They 

 point to the fact that they have grown these 

 crops from year to year on the same fields, 

 yet the weeds in these very fields have 

 increased. This may have been true, but 

 when it has been so, the crops have cer-
