20 FISHERIES OF ALASKA IN 1907. 
lake and in two small, short tributaries. No other of the dozen ormore 
streams entering the lake except the main inlet, or Chilkoot River, car- 
riesred salmon. By far the greater part of the Chilkoot run of redfish 
ascend the main inlet and apparently do not spawn in the vicinity 
of the lake, but far up the stream, beyond observation at the time—the 
glacial turbidity of the water making observation of salmon difficult. 
At the end of September it did not appear that the height of the 
spawning season had yet been reached. Near the head of the lake 
there are considerable springs, making a large pool about 125 feet in 
diameter, which has admirable spawning bottom and held a few 
hundred spawning or nearly ripe salmon. These springs deliver 
sufficient clear water (temperature on September 21, 414° F., or 24° 
colder than the lake) to operate a large salmon hatchery. The 
shores of the lake or the few spawning pools adjacent do not furnish 
an adequate supply of ripe salmon, but eggs could be obtained in 
quantity by barricading the main inlet at or near its mouth and 
holding the fish to ripen in the lake, whose shores in this vicinity 
afford admirable seining ground. The current at the mouth of the 
inlet, however, is strong, and to be efficient a barricade would have 
to be of the most substantial sort. 
The springs mentioned would not furnish a gravity flow for a 
hatchery. The supply would, however, probably never freeze. On 
the west (southwest) shore of the lake there are at least two clear 
streams from which a gravity flow could be obtained through a short 
conduit ; but it is doubtful whether these streams remain open through- 
out the winter. The spawn would have to be brought from the head 
of the lake. 
This examination of Chilkoot Lake included a variety of observa- 
tions on spawning habits, temperature of salmon, hemoglobin con- 
tent of the blood of nearly ripe salmon, and other records of a miscel- 
laneous nature, which data will be held for future publication, together 
with the results of continued studies. 
Dundas Bay.—The success of the season for the cannery of the 
Northwestern Fisheries Company at Dundas Bay was seriously inter- 
fered with by a costly accident on August 2, when the main warehouse, 
in which were stored 14,000 cases of this year’s pack, the season’s 
labels and box shooks, also fishing gear, collapsed and fell into the bay. 
The box shooks, fishing gear, and some of the salmon were saved, but 
4,000 cases of salmon, mostly pinks, were lost, also all of the labels. 
The building itself was a total wreck, and two Chinese were drowned. 
Alsek River.—For some years cannery men, attracted by the Indian 
reports of large runs of salmon in this river, have cast longing eyes 
upon it, and several have made short prospecting trips thither. This 
year a company was organized, composed mainly of Alaskans and 
known as the Alsek Fisheries Company, and an outfit for mild-curing
