FISH-CULTURAL INVESTIGATIONS IN MONTANA AND WYOMING.

with hooks, however, aiul caught nine large Utah chubs ( Leuciscus atrarms). Crawfish 
were also found here. 
Pacific Greek . — From Jackson Lake we traveled across the mountains eastward 
about 12 miles to Pacific Creek. Our first camp on this creek was about 8 miles above 
its mouth. It is here a good-sized creek, 37 feet wide, 14 inches deep, and with a very 
swift current (5 feet per second). The bed of the stream is very rocky, being made up 
of water-rounded glacial bowlders of small size. The banks are low and level, covered 
with a fair growth of bushes, and further back a good growth of pines. Trout were 
found to be quite abundant, no less than thirty very fine ones being taken with the fly 
iu a short time. Most of these ranged in length from 10 inches to 17 inches; one 
very tine specimen, 19 inches in total length, was taken by Prof. Jenkins. Several 
very young trout and a few very small blobs were taken with the seine. Fish food 
seemed abundant. Numerous caddis- worm cases formed of bright-colored granite 
pebbles were found. No crawfish or mollusks were seen. The water is clear and cold, 
the temperature at 4 p. m., August 15, being 62°; at 8 the next morning, when the air 
was 50°, the water was 49°. 
The next day we followed up the narrow valley of Pacific Creek for about 18 
miles and camped about a mile above Inness Lake. WefoundPacific Creek here very 
much reduced in size, it being not over 10 feet wide, 6 inches deep, and having a 2-foot 
current. Temperature at 5 p. m. : water, 59°; air, 66°; at 6 :30 a. m. the air was 38°; at 
9 :15 the air had warmed to 62°, while the water was 50°. A small branch at our camp 
was somewhat colder, the thermometer indicating 48° when the air was 62°. About 
2 miles below this camp Pacific Creek is joined by Mink Creek, which, being the larger 
of the two, should be regarded as the main stream. Trout were found to be abundant 
in Pacific Creek here, but all individuals seen were small. Insect larva* and other 
suitable food for fish were common. 
Inness Lake is the somewhat uncertain name of a peculiar lake lying near Pacific 
Creek, about 1 mile below this camp. So far as I can learn, no name has been given 
to this lake by the U. S. Geological Survey, but u Inness Lake” is the name by which 
it is known to Mr. Hofer. It is about 3 miles long and 4 mile wide. It seems very 
deep in two crater-like depressions, but is rather shallow elsewhere. One shallow area 
was noticed near the center. A part of the bed of the lake and a portion of the shore 
at least are of limestone rock. The lake is surrounded on most sides by low marshy 
meadow. Its outlet is into Pacific Creek. Trout are very abundant in this lake. 
There was scarcely a moment when we were passing from one end to the other that 
one or more trout were not seen rising to insects upon the surface of the water. 
The mountains about here are, in most part, covered with heavy coniferous forests. 
There are, however, among the ridges and upon the sides of some of the mountains, 
small but very beautiful grassy mountain meadows. The journey from Jackson Lake 
up Pacific Creek, while rather rough and difficult, is not attended with any hardships 
or danger. The chief difficulty is in getting through the fallen timber.
