PRESERVATION OF EGGS BY COLD STORAGE.

firsts there was an average of 13.5 inedible eggs per case found by can- 
dling in the commercially packed eggs, as compared with 4 in those 
carefully packed. These figures are the averages of the results of 
monthly observations made from November to March. Figuring the 
value of eggs when stored in the spring of 1917 as 35.6 1 cents per dozen, 
and charging 3 cents a dozen to cover insurance, interest, and carrying 
cost, there was an average money loss in bad eggs in the commercially 
packed eggs of 43.5 cents, as compared with 13 cents per case in those

carefully packed. An average of 11 cracked eggs, which were still 
good by candling, was found in the case of the commercially packed 
eggs . These, however, on account of their impaired shells, would bring 
one-third less on the markets than their companion eggs with good 
shells r making a further additional loss of 12 cents per case. The total 
loss, then, in the commercial stocks averages 55.5 cents per case, as 
compared with 13 cents in the carefully packed eggs. It costs about 
5 cents more per case to grade by candling than by sorting. Even
