8 REPORT OF THE COMMISSIONER OF FISHERIES. 
stock available for distribution in 1907 was larger than ever before, 
it was not sufficient to meet all applications. A new station estab- 
lished in California furnished the most satisfactory eggs handled 
during the season, and is expected to become a valuable source of 
supply for the hatcheries. Attempts to collect eggs of the golden 
trout of Volcano Creek, California, were unavailing, the snow and 
ice on the heights over which it is necessary to pass making it impos- 
sible to transport the necessary equipment during the spawning sea- 
son. Later in the year, however, brood fish were secured and sent 
to three stations, with a view to artificial propagation. 
The hatchery at Northville, Mich., was taxed to its utmost capacity 
during the past lake trout season, 47,000,000 eggs being laid down 
in the troughs at one time. This station supphes practically all the 
lake trout eggs handled by the Bureau. 
Pacific salmons.—The product of blueback salmon was increased 
this year by the large output of the Yes Lake station in Alaska. 
This station, which is now practically completed, has fully demon- 
strated the desirability of its location. With the chinook salmon, 
the work at several important points was less successful than usual, 
because of adverse weather conditions. The racks at Baird, Cal., 
were washed out during the early run of salmon, and almost the 
entire collection of eggs was lost. At Baker Lake, Washington, 
more salmon were caught for the retaining pounds than during any 
preceding season in the history of the station, but an unprecedented 
rise in the lake released many of the impounded fish, and thus the 
total number of eggs secured was not large. The work at the field 
station of Birdsview, which is operated for humpback and silver 
salmon and steelhead trout, was also much interfered with by 
freshets. 
The abundance of salmon in the Sacramento River is evidenced 
by the fact that the Mill Creek substation secured over 40,000,000 
egos—its largest take. The work at Mill Creek is as productive as 
that of any other station on the Pacific coast, and warrants the estab- 
lishment of a hatchery there. 
DISTRIBUTION OF THE OUTPUT. 
The marine and anadromous fishes and the output of the hatch- 
eries on the Great Lakes, all commercial species and constituting 
about 90 per cent of the total output, were as usual planted directly 
by the Bureau or consigned to State fish commissions. Practically 
all the other fishes, except those returned to the streams from whose 
overflow waters they had been taken, were distributed on application, 
as heretofore, being sent to individuals throughout the country for 
stocking ponds, lakes, streams, and reservoirs. The applications in
