20,000 were placed in Pond M for rearing, and an estimated 
number of 30,000 left in the pond, Since then it has been 
drawn down, and 10,500 fingerlings, actual count, taken out. 
These fish were from one to two and one-half inches long, sam- 
ples of which are before you. 
The following extracts are made from the daily record of 
observations more particularly affecting the pond we are en- 
deavoring to follow:

Twenty-four artificial nests placed in Pond P. 
May 6, 1905. 
Forty females and thirty-five males put in pond. 
May 10. 1905. 
Today’s examination showed ten artificial nests cleaned up 
nearly ready for eggs; temperature of water 59° F. 
May II, 1905. 
Water dropped to 52°, caused by cold hard rain. Spring 
water turned on, creek water being very roily. 
May 13, 1905. 
Creek water warmed to 62°; almost clear. Valves, there- 
fore, changed, and it was again turned into pond, being consid- 
erably warmer than the spring water. Male bass cleaning up 
more nests.

found that nearly all had eggs on. Several natural nests 
cleaned up.

five with eggs on were found. Some fungus appears on older 
nests. Temperature of water 63°.
