cent of moisture, and the other varieties and crosses contained about 

 1 per cent less. The appearance of the large cobs of the Whelchel 

 and Aldrich Perfection varieties and the rotting of the ears indicated 

 that the entire ears of these varieties contained a greater excess of 

 moisture than did the shelled grain. In these two cases a correction 

 for moisture content would give a more valuable comparison, but 

 since the moisture content of the entire ears was not determined the 

 comparisons of productiveness are in all cases based on the weight of 

 ears as harvested.

1 Favoring the cross: Ears, 6 out of 10; stalks, 5 out of 10. Average weight of ears per stalk produced by 

 the female parent, 0.52 pound; by the cross. 0.58 pound. Average weight of stover per stalk produced by 

 female parent, 0.94 pound; by tlio cross, 0.88 pound. Increased yield of cross over the female parent: 

 Grain, 12 per cent; stover, —6 per cent.
