and reservoirs, obtaining from them considerable numbers of brook- 
trout eggs for distribution in the fort of fry and fingerling fish to 
applicants throughout Colorado and New Mexico and at the same 
time maintain unimpaired the original sources of supply. In recent 
years this work has suffered from the frequent labor changes occa- 
sioned by the low rate of compensation offered, and in certain in- 
stances the lake owners have refused to permit the continuance of 
fish-cultural work under the direction of the inexperienced men whom 
the bureau has been forced to place in charge. The time is at hand 
when a more definite policy with reference to this field of operations 
will have to be adopted if the work is not to seriously deteriorate. 
SARATOGA (WYO.) STATION. 
[O. N. BALDWIN, Superintendent. ] 
As has been mentioned in several previous reports, this field re- 
mains practically undeveloped because of lack of funds. Ever y year 
the station employees, at the expenditure of much time and labor, 
secure limited numbers of eggs at field stations where, with proper 
equipment and means for eying eggs intended for tr ansfer and for 
the complete incubation of those needed for the maintenance of the 
local run of fish, the egg collections might be very greatly increased, 
the loss of eggs incident to their transfer in the green state obviated, 
operating expenses reduced, and the general efficiency of the work 
greatly improved. During the spring of 1921, with the primitive 
means available, the Sage Creek collecting field yielded 1,185,295 
rainbow-trout eggs, Lost Creek, 982,185, and rCanyon Creek—occupied 
for the first time—351,850, a total of 2,519,830. The station brood 
stock also produced 140,000 eyed eggs of this species. 
Brook-trout eggs to the number of 1,132,400 were handled during 
the year. Of these 134,000 were taken ‘from the station brood stock, 
448,000 were received from Springville (Utah) station, and the re- 
mainder were taken at a new and promising: field station located at 
Big Creek Lake, in North Park, Colo. This field is about 100 miles 
from the Sar atoga station, well up on the Continental Divide. In- 
cubation of the brook-trout eges was completed a full month earlier 
than usual, with the result that most of the fry were taking food 
early. in the winter. 
Incidental to the other fish-cultural work, there are taken each 
season small numbers of Loch Leven-trout eggs, this species appear- 
ing to thrive in the streams of the region. With the more complete 
development of fields contiguous to the station it is probable that 
very successful work can be accomplished with the Loch Leven. 
Besides the species already mentioned, 200,000 blackspotted-trout 
eges were received from Yellowstone Park collections and were in- 
cubated with a loss of only 6,000. The resulting fry and fingerlings 
entered into the general distribution. With improved roads and bet- 
ter transportation facilities there is reason to believe that the black- 
spotted trout will also eventually bear a conspicuous part in the 
operations of the Saratoga station. There remained on hand at the 
close of the year upward “of 1 000,000 eggs, fry, and fingerling fish.
