REPORT OF THE COMMISSIONER OF FISHERIES. 107 
The water of this lake is clear and pure and well suited to ordinary 
lake fishes. The species observed were chubs, sculpins, black bass 
(introduced), sticklebacks, suckers, and cutthroat trout. The chubs 
were spawning; the spawning season of the trout had passed. Bass 
thrive in this lake and attain a weight of at least 4 pounds. Trout are 
plentiful and reach a length of 12 to 18 inches. A species of mud 
turtle, a salamander, and a fresh-water mussel were found to be 
abundant. 
The Bureau has planted in various lots 637,000 common white-fish 
(Coregonus clupeiformis) in American Lake. None of the fish has 
been seen since, and it is not known whether any has survived. The 
physical characters do not indicate that this water is suited to the species. 
Steilacoom Lake.—This lake is next in importance to American 
Lake, and its general characteristics are similar. Its greatest length 
is about 1.75 miles, and its greatest width less than one-half mile. 
Clover Creek and Davidson Creek both flow into it near the southern 
end on the east side. The former is a considerable stream, and is said 
to drain Smith, Tule, and Spanaway lakes, which lie to the southeast. 
The outlet of Steilacoom Lake is through Chambers Creek into Puget 
Sound just north of Steilacoom. The water is shallow, the maximum 
depth being but 17 feet, and the average of 17 soundings being only 
12 feet. 
This lake is of interest chiefly because of the fact that the so-called 
small red-fish occurs in it. The species is said to be seen only in 
October, at which time it-is gaffed in considerable numbers. Whether 
it comes up from the sea is not known to the local residents. The 
other fishes of the lake are chubs (two species), cutthroat trout, large- 
mouth black bass (introduced), sculpins, and sticklebacks. 
Sequallitchew Lake.—Southwest of American Lake and only a few — 
rods from it is Sequallitchew Lake, which is about 1.5 miles long and 
less than one-fourth mile wide, and has a maximum depth of about 17 
feet. It has no tributary streams, and its outlet is through Sequallit- 
chew Creek to Puget Sound. The shallow, muddy bottom and the 
high temperature of the weter do not indicate that this lake is suited 
to white-fish. It is, however, a fairly good trout lake, the cutthroat 
trout being abundant. 
BIOLOGICAL INVESTIGATIONS ON THE COAST OF CALIFORNIA. 
Early in the calendar year 1904 arrangements were perfected which, - 
provided for a cooperation of Stanford University and the University 
of California with the Bureau of Fisheries in a physical and biological 
survey of the waters of the coast of California, and the steamer A/da- 
dross was assigned to the investigation. General direction of the work 
was placed in the hands of President David Starr Jordan, of Stanford
