By W, F. Hubbard. 



Clackamas Hatchery, Oregon, February 4, 1879. 

 To Professor Spencer F. Baird, 



United States Fish Commissioner : 



I beg to report to you as follows : The first spawn of last season was 

 taken September 5, 1878, when we took the spawn from one female 

 salmon, the first one we had caught that was ripe. The next was taken 

 September 7, when we took two females. In spawning the fish, some- 

 times one male would answer for one female ; but we almost always used 

 two, and sometimes three. When fishing, we always caught more males 

 than females. 



September 9 took the spawn from 4 females. 



September 10 took the spawn from 5 females. 



September 11 took the spawn from 7 females. 



September 13 took the spawn from 12 females. 



September 14 took the spawn from 23 females. 



September 15 took the spawn from 22 females. 



September IG took the spawn from 19 females. 



September 17 took the spawn from 32 females. 



September 18 took the spawn from 27 females. 



September 19 took the spawn from 38 females. 



September 20 took the spawn from 36 females.

September 20 took the spawn from 31 females. 



September 27 took the spawn from 24 females. 



September 28 took the spawn from 21 females. 



September 29 the river began to rise, caused by heavy rains, and we 

 were not able to do any fishing, although we took the spawn from four 

 fish which we had in pens built for the purpose of keeping the fish. 



September 30 we took the spawn from three fish from the pens.
