194 CORN CROPS 



It is well to take two kernels from the butt, two from the 

 middle, and two from the tip, of the ear. When a tray 

 has been filled, the grains are covered with a second 

 cloth and a little sawdust on top and thoroughly wet down. 

 When all trays are filled they are stacked up m a warm 

 place and wet once a daj^ for five or six days. All ears 

 that have not shown a strong germination by this time 

 should be discarded. 



IMPORTANCE OF STRONG VITALITY 



137. It should be emphasized that onljr ears showing a 

 strong, quick-growing germ should be used. C. P. Hartley 

 records a typical experiment illustrating this point. ^
