388 AGRICULTURAL REPORT. 
These fish are most abundant in the early autumn, and even as late 
as December. They feed upon white-fish, lampreys, &¢., which are 
found abundantly in their stomachs. They are soslow in their motions 
that it seems incomprehensible how the nimble white-fish can allow 
themselves to be caught. They are fall of spawn from November till 
January. The roe and milt are carried in two large sacs opening into 
the cloaca a short distance from the fundament. They lie beneath the 
intestines when the fish is in its natural position, are four to seven 
inches long, and when full are about four inches in circumference. The 
ova are very minute, and of a creamy yellow color. <A single losh 
contains millions of them. The milt-sacs are smaller, and the milt is 
white. The males are usually much smaller than the females, averaging 
eighteen or twenty inches in length, while the female reaches four or 
five feet. The male has a smaller liver, and one pyriform gall-bladder 
on the left side; some specimens, however, present the physiological 
peculiarity of having two or even three distinct gall-bladders opening into 
the same duct, and uniform in size and shape. We have never seen a 
double gall-bladder in a female. The roe of the white-fish is contained 
in two cylindrical canals running from the gills to the vent above the 
intestines, close to the back-bone. They are never more than an ineh in 
circumference ; the eggs are larger than those of the losh, and of a very 
deep yellow color. 
SUCKER. Catostomus teres, Mitchill; Russian, Kraskee ; Tinneh tribes of 
the Yukon, Stinoyiih. ‘ 
This fish is abundant in the Yukon and other large riversin Northern 
Alaska. It is of moderately large size, reaching five pounds in weight. 
It is generally of a reddish color. The body is so full of bones that it 
is unfit for food, but the heads, when boiled with the roe, make a very 
palatable soup. These fish are filled with spawn in April, a period when 
other fish appear to be out of season. The eggs are of moderate size, 
of a yellow color, and are contained in triangular sacs, one on each side 
of the visceral cavity. 
BLACK-FISH. Cottus? sp.; Russian, Tchorny riba; Tinneh tribes of the 
Yukon, Undik; Kutchin tribes of the Upper Yukon, H’leeweh. 
A smali cottoid fish, about three or four inches long, is caught in bas- 
kets made of grass, in the spring-time in the Yukon Territory. It is 
found in the greatest profusion in the shallow ponds in the Kaiyuh 
marshes, and is principally used as feed for dogs, though occasionally 
eaten by the natives. lt has a muddy, sweetish taste, and is of value 
only on account of the enormous numbers in which it is taken. Holes 
are cut in the ice in April and May, when these little fish swarm about 
them, and are dipped cut with net-like baskets. 
A small cyprinoid fish, measuring three or four inches in length, is 
caught in some of the small rivers in summer with pin-hooks, and is 
eaten raw by the natives, who regard it as a delicacy, under the name 
of aliweetly. 
This completes the list of the economical fresh-water fishes of Alaska, 
as far as known at present. The fishery is carried on in summer in some 
localities with gill-nets, and in others with seines, which are manufae- 
tured by the Tinneh tribes out of the inner bark of the willow and alder, 
and by the Innuit out of fine seal-skin line. In the Hudson Bay Ter- 
ritory pounds are established by the traders, and also by the Kutchin 
indians, in which a considerable number of fish are taken. In winter the
