CORN JUDGING 67 



Tlie second kind of space between rows is the space 

 between kernels at the tip about the point where the 

 kernels are attached to the cob. In order to examine the 

 ear for this point it is probably necessary to shell off a 

 space four or more rows in width and four or more inches 

 long on one or more ears in the samples. This examination 

 may be made at the time and on the ears tested for per 

 cent of corn to cob. Examine the sides of the rows first, 

 and if there is space the openings between the tip sides 

 of the kernels can easily be detected. Turn the ear so 

 that the end, either tip or butt, points toward you, and 

 examine the ends of the rows down near the cob. When 

 there is space, the openings between the tips of the kernels 

 can easily be seen. This kind of space is extremely im- 

 portant from the fact that it is a result of poorly shaped 

 kernels, usually low in vitality and lacking the important 

 elements of composition. 



Per Cent ov Corn 



The proportion of corn to cob is determined by using 

 every other ear in the sample. Weigh the five ears. 

 Shell off the grain. Weigh the cobs. Subtract the 

 weight of cobs from the weight of ears, and the weight of 

 the grain will be obtained. Divide the weight of the 

 grain by the total weight of the -Kve ears, and the per cent 

 of corn will be obtained. For every per cent short of 

 standard cut .5 point. 



The proportion of co*n to cob depends in part on 

 the maturity of the ears. If the ears are thoroughly 

 dried out the percentage will be greater than in the moist 

 ears. 



Storing Seed Com — Many corn breeders dry the seed 

 ears by artificial heat. The ears are put up in a tight 

 room arranged for ventilation as follows: Set 2x8 up- 

 rights along the floor the long way of the room, begin- 

 ning with the first row about 18 inches- from the
