The cannery obtained its fish principally frorp the Home Stream, Sar-Kar, 
Warm Chuck, and Hetta. 
In order to continue the data for the Klawak Stream, given in my former 
report, the following record may be added:

The Albatross did not visit the cannery this season, and the above information, 
together with the following, was obtained by interviews with the superintendent. 
Klawak Hatchery . — This hatchery, described in former report, was moved in 
1898 from the head of the main stream to the mouth of Three-mile Stream, a lake 
feeder on the northern side. The new hatchery house is 60 feet by 18 feet, and 
contains twelve troughs, 16 feet by 11 feet, arranged in pairs, with a passage around 
each pair. There are 6 baskets to a trough, each basket holding 50,000 eggs, giving 
the hatchery a capacity of 3,600,000 eggs. The hatchery water is supplied by a 
flume from the head of the feeder. About 50 yards within the mouth of the feeder 
a fence with a trap holds the spawners, from which they are seined as wanted. 
The only hatchery data available is the following: In 1898, July 23 to August 26, 
736 females were stripped, obtaining 2,586,000 eggs, 2,150,000 of which were hatched. 
This would give 3,513 eggs to the fish and the loss about 17 per cent. 
The highest and lowest monthly temperatures of the water are as follows: June, 
48°, 44°; July, 48°, 46°; August, 54°, 50°; September, 52°, 44°; October, 46°, 39°; 
November, 44°, 32°; December, 40°, 35°. At a temperature of 50° F. the fish are 
hatched in about 70 days; the longest period of incubation thus far has been 120 days; 
eye-spots appear in 27 days, and the egg-sac is absorbed in 42 days. 
The young fish are siphoned from the troughs into buckets as soon as hatched, 
and planted in a shallow part of the lake. It is said here that the young fish go to 
sea the spring of the second year after the parent fish has entered the stream. The 
milt of 2.5 to 3 males is used for impregnating the eggs of every full female. This 
year (1900) several thousand young fish were marked by cutting off the fleshy fin. 
The following is the output for three years: 2,586,000 eggs and 2,150,000 fry 
in 1898; 3,600,000 eggs and 3,000,000 fry in 1899; 3,600,000 eggs, about 1,000,000 fry 
in 1900 (nearly all eggs were lost by a hard freeze). 
Information was received that, owing to the very severe weather in Alaska this 
year, all the eggs in the hatchery were frozen. 
HUNTER RAY. 
Pacific Steam Whaling Company . — Time did not permit a visit to this cannery 
during the season of 1900. The cannery and the district were visited in 1897 and 
fully described in my former report, pages 68 to 73. 
The following statistics and additional information were obtained by personal 
interviews with members of the company and the cannery superintendent.
