FISH-CULTURAL INVESTIGATIONS IN MONTANA AND WYOMING.

any lisli in the lake, but on October 7 Mr. Hofer was passing along the east shore of 
Shoshone Lake and reports seeing seyeral trout rise to the surface out about 75 yards 
from the shore. He also reports seeing trout at a beaver dam in Heron Creek about 
1.1 miles from the lake. Whether any of these were lake trout could not be certainly 
determined, but the probabilities are that those seen in the lake were lake trout, while 
those in the creek were Loch Leven trout. Finding them so numerous in the creek 
would seem to be very satisfactory and positive evidence of the success of this impor- 
tant planting. 
Fast Forlc of Gardiner Hirer . — This stream was stocked September 22, 1889, with 
9G8 native trout gotten by Mr. Lucas from Howard Creek. We made a somewhat 
hurried examination just above Undine Falls and caught one trout, GJ inches long. 
There seems to be a question as to whether this stream did not already contain trout 
before this plant was made. The nature of the divide between this stream and Black- 
tail Deer Creek, in which there are no falls, makes it quite possible for trout to get 
over from Blacktail Deer Creek, which is well supplied with trout. This, of course, 
makes it impossible to say whether the trout taken by us is of the plant or not. 
NOTES ON MAMMALS NOTICED IN MONTANA AND WYOMING. 
Though no special attention was given to the mammals found in the region trav- 
ersed by us, no specimens collected, and no special attempt made to list the species of 
the region, yet numerous notes were made upon some of the species observed. Such 
of these notes as seem to be of value are given here. 
1. Arctomys sp.f 
Ground hogs were seen in several places south of the Yellowstone National Park. 
On Pacific Creek, not far below Two-Ocean Pass, we saw a pair of old ones and four 
or five half-grown young, one of which our dog killed. Dr. Merriam informs me that 
the marmot found there is probably Arctomys dakota. 
2 . Tamias sp.? 
Chipmunks were frequently seen about Flathead Lake, on Dempsey Creek, at 
Missoula, and perhaps other places. Two different species were probably seen. 
3. Sciurus richardsoni Bachman? 
A squirrel, likely tins species, was abundant at Swan and Flathead lakes, Mis- 
soula, and the National Park. 
4. Castor canadensis Kuhl. 
Fresh signs of beaver were seen at Beaver Lake, Willow Park, and on Lewis River 
just below the Upper Falls; also near the mouth of Beaverdam Creek. 
5. Lagomys princeps Rich. Rocky Mountain pika. 
Several were seen near Obsidian Cliff in National Park; and four or five others 
were noticed in a rocky slide on the divide between Shoshone Lake and the Fireliole 
River. 
6. Cervus canadensis Erxleben. 
A drove of sixteen elk was seen on Pacific Creek below Two- Ocean Pass. Several 
young elk were seen at Horsethief Springs. They had been captured in the mountains 
near by and were being raised by hand by Mr. Marshall. This man does quite a 
thriving business rearing elk and deer in this way and selling them to owners of pri- 
vate parks in the Fast.
