48 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
P. Sauerhoff, an expert carpenter, who had had many years’ experience 
in the fish-cultural work of the Commission, On September 21, Mr, EH. 
M. Robinson, for a number of years connected with the Commission, 
and who had been in charge of fish-cultural work at several of its 
stations, was appointed superintendent. 
- An additional appropriation of $20,000 having been made August 30, 
1890, for the completion and equipment of the station, plans and speci- 
fications were prepared for a superintendent’s dwelling and_ stable. 
After due advertisement, contracts were madein May, 1891, at $5,887.93 
for the dwelling, with Messrs. Baldwin & Chronister, and at $1,820 for 
the stable and wagon house, with Mr. W. W. Cable, both contractors 
doing business in Leadville. The supervision of the work of construc- 
tion was placed in charge of Mr. George H. Tolbert, under the general 
direction of Mr. H. D. Dean, who was appointed superintendent on 
April 15, 1891, sueceeding Mr. Robinson, who had resigned to take 
charge of a private fish-cultural establishment. 
1889-90. 
The period of active fish-cultural operations extended from Novem- 
ber, 1889, to June 30, 1890, the collection of eggs being 568,000 of the 
brook trout previously referred to, and 12,000 of the black-spotted trout. 
In addition to these there were 25,000 brook trout eggs and 20,000 Loch 
Leven trout eggs forwarded from the Northville Station. 
The distribution of brook trout eggs included 50,000 to Fort Gaston 
Station, California, and 25,000 to Northville Station, Michigan. The 
remainder of the eggs were retained for hatching and rearing, with 
the exception of 126,800 fry, which were given to Dr. John Law, in 
exchange for the use of his stock fish. 
There were collected from Twin Lakes 1,014 black-spotted trout for 
breeding purposes, and from Rock Creek, 32; 100 of these were for- 
warded to Wytheville Station. From Rock Creek there were collected 
58 brook trout. 
1890-91. 
The eggs obtained this year from the stock brook trout of Dr. John 
Law amounted to 180,000. They were of the later yield, and defective 
in fertilization, as a result of the scarcity of milt. From these a ship- 
ment of 5,000 was made to the Wyoming Fish Commission, at Laramie. 
The eggs retained hatched at different times, and a high mortality oe- 
curred among the fry as a result ofcannibalism. The number remaining 
on hand May 1, 1891, was but 41,000. 
In addition to the eggs taken by the station, 20,000 brook trout eggs 
were obtained from Caledonia, N. Y., January 31, 1891. On May 1 the 
fry from these amounted to 14,000. 
A consignment of 100,000 eggs of Von Behr trout was presented by 
the New York Fish Comunission, the young therefrom being 68,000 on 
May 1.
