GRADING. 



The question of grading corn has already been referred to in tlie 

 paragraph above. As indicated, it is common practice to remove tip 

 and butt kernels for the sake of uniformity in size of seed for planting 

 where the planter is used. It is also coming to be a common practice 

 to further grade the corn by the use of screens, separating the corn into

two or three grades and then selecting a size of plate for each grade 

 of corn respectively. It will readily be seen, that a plate hole of proper 

 size to receive the medium kernel might receive two of the smaller ker- 

 nels and would not receive one of the largest kernels. But, in the case 

 of planters having plates with holes to carry three kernels instead of 

 one, if the hole were of sufficient size to carry three medium kernels it 

 would carry five or six of the smallest and possibly but one of the 

 largest. This would result in the case of ungraded corn in a very ir- 

 regular drop, and therefore, in a very irregular stand.
