REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Leapvillk Station', Colouado (II. D. Dicax and Yj. A. Tulian, Superintendknts). 



The work at this station during the fiscal year was directed by H. D. 

 Dean and E. A. Tulian, superintendents, the latter relieving Mr. Dean 

 on February 7, 1895. 



Bepairs, etc. — During the year 400 feet of 6-inch wood pipe was laid 

 from the large spring and connected with a 3-inch pipe to the hatchery, 

 thereby increasing tlie water supply to 90 gallons per minute. A new 

 waste overflow from the reservoir was also put in, the old one not 

 being adequate. A substantial flshtrap 'was constructed in the creek 

 connecting Upper and Lower Twin Lakes at a cost of $500 and a 

 watchman's shanty built near it. A flagpole 05 feet high was erected 

 at the station and mucli other work done toward imi)roving the grounds 

 and buildings. 



The following table shows the stock of fish aud eggs on hand at the 

 beginning of the fiscal year : 



There were heavy and unaccountable losses of fry and adult fish 

 during the summer months. Every possible effort was made to check 

 the death rate, but without avail. The adult fish were apparently 

 suffering from diseases of the gills, but there was no visible cause for 

 death in tlie case of the fry. A number of the specimens sent to head- 

 quarters were carefully examined, but failed to show any disease of 

 the organs. 



The regular distribution was commenced by car I^o. 3 on October 27 

 and finished December 4, though a small part of the stock was dis- 

 j)osed of in July, August, and September. 



The total number of fish distributed was 70,325 brook trout, 570 

 rainbow trout, 1,475 black-spotted trout, and 870 Loch Leven trout; in 

 all, 73,240, less than 50 per cent of the stock on hand at the beginning 

 of the year. 



liroolc trout. — During the summer arrangements were made with the 

 owners of WelUngton, Uneva, and xVspen lakes for the collection of 

 trout eggs on shares, the owners to get one-half of the fry resulting 

 from the eggs collected, and the United States Fish Commission to pay 

 all expenses. The first eggs were taken at Uneva Lake on August 11, 

 and at Wellington on November 8. By the close of the season 1,754,700 

 eggs had been collected from all sources, as indicated in the accom- 

 panying table.
