 equal divisions, the third is an arbitrary grouping, and the fourth in-

Eggs Weighing 26 Ounces or Over per Dozen Form Important Group 



About 25 per cent of all eggs sold on the New Hampshire Egg Auc- 

 tion average at least 26 ounces net per dozen as compared to about 

 23 per cent of medium size, 10 per cent of pullet size, and 3% per cent 

 of peewee size eggs. Thus this group of very large eggs is more impor- 

 tant than any of the three smaller sizes which have been "officially rec- 

 ognized" in standpoint of size and the range in weights which it covers. 



It seems unreasonable to recognize a peewee group as a market grade 

 when it constitutes only about 3^/2 per cent of all eggs sold and ignore 

 a very large group which constitutes 25 per cent of all eggs sold. 



The grouping under our present grades is as follows: 



100% 



What appears to be a more practical grouping could be made without 

 increasing the number of sizes by combining peewees and pullets into 

 one size group called small and creating a very large group as follows:

 Medium
