HISTORY OF SAMPLES. 
Most of the samples of breaking-stock eggs used for the investiga- 
tion were procured from the current receipts of com m ission houses 
located in an eastern consuming center. In a few instances in the 
beginning of the season samples were purchased from grocery stores. 
Late in the season the samples consisted of breaking-stock eggs 
sorted from e££s cominsr from storage. The firms from whom most 
of the samples were obtained operated egg-breaking plants in addi- 
tion to their wholesale business. Most of the eggs were produced 
either in the Middle "Western States or in Virginia , and were shipped 
to the consuming center, after the weather had become warm, in 
refrigerator cars. The time occupied in making the haul Varied from 
3 to 12 days. The history of each sample is given in Table I.
