Which do you believe have the largest amount of protein and are worth 

 most for feed? 



6. Soak a number of kernels of corn in warm water, then separate 

 them into the following parts: hull, tip-cap, horny gluten, germ, 

 crown or white starch, and horny starch. With the exception of the 

 horny gluten, a thin layer just under the hull, there will be no difficulty 

 in separating the parts. See Fig. 39. 



7. Secure two samples of corn, one graded, the other ungraded, and 

 a horse corn-planter. Block up the planter until the wheels turn free. 

 Put in some of the ungraded seed, and run the planter until 100 hills 

 have been dropped. Count the kernels dropped for each hill, and find 

 the number of hills in 100 for which just three kernels were dropped. 

 This will give the percentage of a perfect drop. Repeat the process, 

 using the graded seed and changing the plates until the most perfect 

 drop possible is secured. It may be necessary to file the holes in the 

 planter plates to get them just the right size, but it is better, if possible, 

 to secure new plates.
