LX REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



in April exceeded the total number ever secured at any of the shad 

 stations of the Commission in a single season, the largest heretofore 

 recorded being 105,125,000 at Battery during the year referred to above. 

 Work continued uninterruptedly until June 9, the collections in May 

 aggregating 95,510,000 and in June 9,118,000, making a total of 

 209,992,000 for the season. Of these, 140,337,000 were purchased from 

 fishermen at $20 per 1,000,000; the balance was taken by the regular 

 spawn- takers. The capacity of the hatchery was severely taxed from 

 the beginning of the season on account of large collections during 

 the first ten days, but the pressure was partly relieved by transferring 

 eggs to Central Station, Washington. Car No. 3 was equipped as a 

 hatchery and stationed at Perryville. The low temperature prevailing 

 at this time, however, retarded development to such an extent that 

 the hatchery was soon filled to overflowing, and it became necessary 

 to plant large numbers of eggs on the spawning-grounds.
