and the largest 15 by 40. These were constructed with 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 Mary irrigating 
ditch. As the temperature of the lake water rose to 70° F. in the 
warmer portion of the day, half of the station supply was obtained 
during summer from the ditch. In September the establishment was 
threatened with forest fires, requiring 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, under going 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 effected between November 12 and December 24, 
the fish being sent for the most part to Colorado, Montana, North 
Dakota, Nebraska, and New Mexico. Those furnished for distribution 
are as follows: Loch Leven, 2,600; rainbow, 1,550; Von Behr, 30,050; 
brook, 98,200; black-spotted, 46,500. 
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. Asa 
result of attempting 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 excepted. In October, when the adults were placed in the
