[7] OPERATIONS AT THE NORTHVILLE HATCHERY. 10-1:3 



plenty of ripe fish at command, one man can readily take two or three 

 million eggs daily. I have taken, on more than one occasion, under 

 partial adverse circumstances, 2,000,000 eggs in a day. It will be seen, 

 then, that but few days in the aggregate, at the right time, are required 

 to secure great numbers. Indeed, taking the seasons as they average, 

 only a small cori)s of spawn-gatherers are necessary to collect any 

 reasonable number of eggs. 



Mr. Wires, with one assistant, obtained eggs as follows : 



Nov. 10 25,000 fi'om 2 females. 



Nov. 19 100,000 from 6 females. 



Nov. 20 100,000 from 7 females. 



Nov. 21 200,000 from 11 females. 



Nov. 22 1,000,000 from 40 females. 



Those taken November 16 were from trap-nets, the remainder from 

 gill-nets. Besides the 1,425,000 whitefish eggs taken and sent on to 

 Northville in good condition by Mr. Wires, some 60,000 eggs of lake 

 trout were taken from 10 spawners on the last day of October, and for- 

 warded to Northville in good shape the day following. 



Below is Mr. Wires's record of temperatures and weather observations 

 made each day at 12 m. :
