 wlien such grains are fed to sheep, unless 

 they are ground, a portion of the weed seeds

 into the manure, and thus into the soil of 

 the farm. When fodders containing weed 

 seeds are purchased, the seeds contained in

 the conflict with weeds, the land should be

 of soil we can easily get two crops a year ; 

 and where this can be done, the necessary 

 cultivation will be found very helpful in the 

 work of destroying weeds. The nature of 

 the crops to be so raised will naturally 

 depend largely upon climate, soil, and the

 sown in the autumn, and be followed the
