arrived, and the fish remaining in the inclosure were seined up for 

 manipulation. It was then found that out of the 232 salmon supposed 

 to have remained on hand after July 10 but 59 remained to us, 40 males 

 and 19 females. 



4. — The spawning. 



The fish gave evidence of approaching maturity as early as October 

 20, and on the 24th the first spawn was taken. The following state- 

 ment exhibits all the spawning operations in detail: 



Record of spawning operations at Dead Brook. 



* These weights are estimated. 



From these details we obtain the following generalizations : 



Inches. 



Average length of the 19 females 32. 5 



Pounds. 



Average weight of same, exclusive of spawn 11.2 



Average weight of same, inclusive of spawn 14. 9 



Total weight of spawn taken 71. 3 



Average weight of spawn from each female 3. 7 



The number of the eggs was underestimated. When those remain- 

 ing sound in mid-December were packed for shipment they amounted 

 to 200,500, and 11,192 by count had been picked out; total, thus com- 

 puted, 211,692.
