204 AGRICULTURE. 



Often many annoyances and disappointments 

 would be averted, and much time and labor 

 saved, if proper attention were given to the 

 quality of the seeds sown. Bad seeds not only 

 result in partial or total failure of the crop, but 

 may be the means of introducing noxious weeds 

 as, the plantains. A field is frequently sown 

 in bracted plantain when it was meant to be 

 sown in red clover. The principal points to be 

 considered in determining the quality of seeds 

 are purity and vitality. 



2. Purify. Various impurities may exist, 

 either incidentally, or purposely, in commercial 

 seeds such as inert matter, or seeds of other 

 useful or injurious plants any of which would 

 make the seeds more expensive if not altogether 

 objectionable. Purity of seeds may be tested 

 by carefully examining with the eye or lens, if 

 necessary a fair sample of the seeds to be 

 planted. 



3. Vitality of Seeds. In the testing of seeds 

 it is not safe to rely upon general appearances 



such as form, color, and odor but the seeds 

 must be actually tested to be certain of their 

 vitality. 



EXPERIMENT 15. (a) From each kind of seeds de- 

 sired, select at random a certain number, according to 

 the quantity to be planted. 



(fi) If the seeds are large, it may be advantageous to 

 soak them a few hours.
