6. Which is the better ear, one weighing 27.2 ounces with a per- 

 centage of 81.9 grain, or an ear weighing 20.8 ounces and yielding 86.8 

 per cent, grain? What was the difference in weight of grain of these two 

 prize winners at the Blue Grass Corn Show in Kentucky in 1909? 



7. Six ears of white dent corn placed on exhibition by six different 

 Kentucky growers, yielded on an average 84.2 per cent, of grain. If the 

 average weight of grain was 18.63 ounces per ear, what was the average 

 weight of the ears? 



8. The six ears with the highest percentage of grain shelled at the 

 Blue Grass Show in Kentucky in 1909, produced on an average 87.19 per 

 cent, grain ; the average weight of the ears was 16.95 ounces. What was 

 the average weight of the cobs? 



FIG. 2. Electrically welded wire fencing, cut without waste, into wire racks 



for drying and storing of seed corn. Without touching and in a 



breezy location the seed ears dry promptly and retain 



their full productivity. 



9. If the circumference of a well proportioned ear of corn should 

 be to the length as 3 is to 4, what should be the length of an ear 7.5 

 inches in circumference? What should be the circumference of an ear 

 9 inches in length? 



10. If 1,700 pounds of corn were shelled from 2,000 ears of corn, 

 and the weight of the cobs was 300 pounds, what per cent, of the weight 

 of the ear was cob? What was the average weight of the ears? What 

 was the average number of ounces of grain per ear?
