and the largest 15 by 40. These were constructed Avith plank sides, 

 the smaller ones being also planked on the bottoms. 



As the result of the breaking of the bank of the lower lake, May 27, 

 the water supply for a month was obtained from the De Maiy irrigating 

 ditch. As the temperature of the lake water rose to 70° F. in the 

 ■warmer portion of the day, half of the station sui)ply was obtained 

 during summer from the ditch. In September the establishment was 

 threatened with forest fires, re(iuiring some labor to save the building. 

 A snow-fall of 5 inches, October 31, removed the danger. 



Egg collections were made at two periods, the first from November 

 to January, inclusive, and the second in May and June. There were 

 brought over from the preceding year eggs and fish represented in the 

 table which follows :

Of the eggs of the black- spotted trout there were shipped in July the 

 following: H. M. Orahood, Denver, Colo., 30,000; G. Schnitger, Laramie, 

 Wyo., 25,000 ; Otto Gramm, Laramie, Wyo., 5,000 ; total, 60,000. All the 

 other eggs were hatched, 15,000 black-spotted fry being transferred to 

 the Wytheville Station in July. 



Losses among the younger trout, undergoing rearing, may be inferred 

 from the following statement of numbers on hand September 30, by 

 count: Black-spotted, 77,100; yellow -finned, 250; rainbow, 1,800; brook, 

 105,300; Von Behr, 34,000; Loch Leven, 4,900; total, 223,350. 



Distribution was eflected between November 12 and December 24, 

 the fish being sent for the most part to Colorado, Montana, Nortli 

 Dakota, Nebraska, and New Mexico. Those furnished for distribution 

 are as follows: Loch Leven, 2,G00; rainbow, 1,550; Von Behr, 30,050; 

 brook, 98,200; black-spotted, 40,500. 



In November 5,000 black-spotted yearlings were transferred to North- 

 ville Station. There were also distributed 23,000 hybrid trout, 300 of 

 which were forwarded to the Central Station, Washington, D. C. As a 

 result of attemjiting to hold over a considerable number of yearling Von 

 Behr trout during the winter, 17,000 were lost, it being impracticable to 

 induce them to take food in the low water-temperature prevailing. 



Materials collected and forwarded to the World's Fair, Chicago, con- 

 sisted of black-spotted and yellow-finned trout, showing development 

 up to six years. Adults, 375 in number, reached destination without 

 loss. In addition to the live fish, alcoholic specimens of ovaries, eggs, 

 and embryos were furnished. 



Brook trout. — Observations at this station point to the superiority 

 of the brook trout over all others for Colorado waters, native varieties 

 not being excei^ted. In October, when the adults were placed in the
