Ikivc been a hill, whether any stalks are there or not.) Husk the corn 

 and weigh it. Secure also the yield from the best hill and from the 

 poorest. At what rate does the corn yield to the acre? How much 

 would it have yielded had there been a perfect stand of 3 bearing stalks 

 per hill? How much corn would have been produced to the acre had 

 there been a perfect stand and every hill yielded as much as the best hill? 

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

 a ho^se 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 

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

 the number of hills in 100 for w^hich 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 l^e necessary to file the holes in the 

 planter plates to the right size, but it is better to secure new plates.
