576 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [24] 
carrying cases, thus avoiding the expense of new trays by utilizing those 
on hand. This was completed December 22, and the following day 
1,000,000 eggs from a lot received at the hatchery November 6, were 
placed in chambers 1 and 2; January 5, 1,500,000 from lot received No- 
vember 13, were transferred to chambers 3,4,and 5; and the remaining 
chambers were filled January 12, with 1,000,000 eggs from lot received 
November 13. The eggs were treated the same as those in the smaller 
refrigerator in regard to sprinkling and picking, but the temperature 
inside the larger one was maintained one degree higher on an average, 
while 29° was the lowest limit allowed the atmosphere surrounding it. 
The temperature inside ranged from 31° to 34°, averaging 32°. The 
eggs from section one, one-half million, were removed January 10, for 
shipment tolowa. Section 3, containing the same number, was likewise 
emptied January 13, for Kentucky and Minnesota shipments. The two 
and one-half million remaining were retained in their respective sections 
(2, 4, 5, 6, and 7) until February 1, when all were transferred to the 
hatching jars. A jar of eggs from section 2 began and completed hatch- 
ing almost simultaneously with eggs received at hatchery, November 
18, showing a retardation of twelve days. By comparison with eggs 
of various ages continuously developed in water, sections 4 and 5 showed 
a detention of ten days, and sections 6 and 7 a retardation of 94 days. 
The fry from ail these were equal in vigor and development to those 
brought forward in the usual manner. Previous experiments in retard- 
ing eggs of the whitefish have given substantial evidence that the eggs 
should be taken from the water earlier in the season to secure the longest 
possible postponement of the hatching period.
