it in time for experimental work in the fall of that year. The hatchery is located at 
the head of the lake, between the dry bed of the torrent and the streamlets flowing 
from the cascade, and near the latter. It consists of a log and rough-board building, 
20 by 30 feet, shingle-roofed, having at one end a room iiartitioued off for the super- 
intendent’s quarters, and in the space at the other side of the same end, a boiler and 
pump were installed in 1897. 
There are eight hatching-troughs, each 16 feet long, 12 inches wide, and 11 inches 
deeii, made of uniilaned and unpaiuted boards, 1 inch thick and 12 inches wide. They 
are arranged in three pairs and one ageinst the wall, on either side of the building^ 
leaving four jiassageways between them. There are six compartments in each trough, 
30 inches long, separated by solid wooden partitions 6 inches high, joined tightly to the 
bottom and allowing the water to flow only over the top. In each compartment are two 
J-inch round iron rods, fixed transversely |-inch from the bottom, for the baskets to 
rest upon. The baskets are 24 by lOJ by 6 inches, and hold about 25,000 eggs. 
Water from the cataract, a few hundreds yards back of the hatchery building, 
is conducted by a box flume to the northeast corner of the hatchery building into a 
transverse distributing-trough, from which it passes through the hatching-troughs, 
and thence by a waste-pipe out of the building. The arrangement of the partitions 
allows only circulation over the top. There was no record kept of the operations in 
the fall of 1896. About one week after they had commenced to gather eggs, and had 
200,000 in the baskets, unexpected cold weather set in and not only froze the flume 
solid, but froze up the whole cataract. Being without water, the eggs were put in the 
lake and left to their fate. It was the intention for 1897, in the event of a freeze, to 
pump from the lake and use a filter. The water from the cataract is about 8° lower 
in temperature than the lake water. The fish are taken from the lake in seiues, and 
those that are ripe are stripped, while the rest are retnrned to the lake.

VICINITY OF REDFISH BAY, ETC. 
Little Whale Bay, about 20 miles to the northward of Redfish Bay, has a stream 
from which 2,000 to 3,000 redfish and the same number of cohoes are taken. 
Necker Bay, next north of Whale Bay, has a stream which is remarkable for the 
large run of small redfish. The average number of fish per year taken from this 
locality by the cannery during the past nine years is 40,000; the largest number in 
any one year was 105,572. They are fully matured, I am told, and run from 28 to 30 
to the case. This would give an average of rather less than 2^ pounds in weight, and 
it is asserted that every year the fish average about the same in weight. 
The Redoubt, referred to under the cannery history as the first location of this 
cannery, has a short outlet to a large lake and was a favorite place of the Russians and 
the principal source of salmon supply for the Sitka colony. It was dammed solidly 
for years, and from a stream out of which many thousand salmon were formerly taken 
each year, the catch has dwindled down to about 6,000.
