fidence of its producers if the system is to be successful. However, some 

 hatcheries consider it too much work. 



In this area, premiums usually refer to a given number of cents per 

 dozen over the Boston wholesale market. The premium in the case illustrated 

 here is based on a 75 percent hatch, with a sliding scale for higher or lower 

 hatchability. 



Twenty New Hampshire producers who made about 500 shipments of 

 eggs in 1948 had hatchability ranging from 64.6 percent to 82.4 percent 

 and averaging 73.8 percent. If a premium had been paid on hatchability 

 over 75 percent as shown above, additional returns would have been re- 

 ceived on 43 percent of the lots shipped.

Types of Egg Cases Used 



The types and condition of egg cases used are of interest in that they 

 have a bearing on both breakage and costs. 



In Table 8, only those producers have been included who reported 

 kinds of egg cases used and the average number of cases shipped weekly 

 so as to weight the average figures. Data cover 67 shippers making average 

 total weekly shipments of over 1,000 cases of hatching eggs.
