were used in the com planter, the number of grains dropped at 

 one time varied from one to six grains, the planter dropping 

 three grains to the hill sixt}^-six times out of a hundred. When 

 only the middle grains of the ear were used, the planter dropped 

 two grains eight times and three grains ninety-two times to each 

 hundred hills. Since uniformity of stand is essential to maxi- 

 mum yield, it is therefore good practice to discard the largest of 

 :he butt and the smallest of the tip grains. It is also found 

 that in order to secure imiformity of stand it is essential to select 

 ears having grains of uniform size. It was found that when 

 long and short grains were mixed together, the planter dropped 

 three grains sevent}*-five times out of one hundred; while when 

 planted separately with proper plates for each, the planter dropped 

 three short grains ninet}'-five times out of one hundred and 

 three long grains ninety-two times out of one hundred.
