PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1921. 19 
at the close of the fiscal year 4,000,000 of these young salmon, which 
will be reared to a larger size before liberating. In connection with 
its rearing operations the bureau is indebted to the fish and game 
authorities of the State of Washington, which furnished without 
charge 1,000 cases of canned salmon “ do-overs” to be utilized as food 
for the fish. 
The improved run of sockeye salmon in Baker Lake seems espe- 
cially noteworthy from the fact that for more than 20 years the main- 
tenance of the run of this species has depended almost exclusively on 
artificial propagation. It has been the custom at this point to trap 
all fish as they enter Baker Lake from the river and transfer them to 
an inclosure near the head of the lake, where they are held until 
ready to spawn. Thus, only the comparatively few fish which occa- 
sionally escape the trap during high-water periods spawn naturally 
in the lake. 
In addition to the sockeye-salmon operations 700,000 silver-salmon 
eggs were taken between November 17 and December 15. In pursu- 
ance of the adopted policy of reserving Baker Lake so far as possible 
for the propagation of sockeye salmon, these eggs were transferred 
to the Birdsview hatchery immediately after being eyed. 
BIRDSVIEW (WASH.) SUBSTATION. 
The work of the Birdsview substation, on the Skagit River, was 
also successful. Its output of chinook salmon was larger than in any 
previous year, and the collections of silver and steelhead salmon 
eggs were above the average. This substation is now dependent 
on the fish that enter Grandy Creek for its egg collections. The 
trap in Phinney Creek, formerly a valuable egg-producing stream, 
was destroyed by floods two years ago, and since that time funds for 
its replacement have not been available. The success of the work at 
this point is attributed largely to the favorable water stages which 
prevailed throughout the spawning season. The streams in this 
locality are subject to sudden and violent fluctuation, and not in- 
frequently at the spawning season the water is at such a low stage 
as to make the ascent of fish difficult, if not impossible. Of passing 
interest is the collection of 13,500 sockeye-salmon eggs from fish 
taken in Grandy Creek, the result, apparently, of plants of that 
species made by the bureau in Grandy Lake. 
BRINNON, DUCKABUSH, AND QUILCENE (WASH.) SUBSTATIONS. 
The propagation of chum salmon at the three substations on Hood 
Canal—Brinnon, Duckabush, and Quilcene—was unusually successful 
from the standpoint of egg collections and numbers of fry pro- 
duced. Thirteen million eggs of this species, taken in Walcotts 
Slough, at the Brinnon substation, represented the largest number 
of eggs taken in that region. The egg collections do not accurately 
represent the numbers of spawning fish in the streams, since many 
escaped during the high-water stages, which were frequent during 
the spawning period and adversely affected the work at all points 
on the canal. 
There are two distinct runs of chum salmon in the tributaries of 
Hood Canal. The spawning of the first, or summer run, occurs
