pine woods among the mountain mahogany and chaparral. Unlike 
the large Townsend's Chipmunk, it is always in sight and rarely if 
ever climbs trees. On the west or Rogue river side of the mountain, 
Mr. Preble did not find it below Union Creek, about 16 miles from 
Crater Lake, and thinks this marks its lower limit on that slope. 
Large Gray Ground Squirrel. Spermophilus douglasi, Rich- 
ardson. 
Klamath Indian name, Cho-chuck. 
Common in the lava rock of the Transition Zone on the east 
side of Klamath Lake, and at Prospect in the upper Rogue river

Merriam.

Abundant everywhere about Crater Lake, on the summit of the 
mountain, and also in the Yellow Pine belt about Fort Klamath.

in the rock slides with the Pikas (Ochotona). On the west slope 
Mr. Preble found them in the upper Rogue river valley 15 or 20 
miles below Crater Lake. Mr. Preble caught a young one on Anna 
Creek the first week in September, and took it down to Fort 
Klamath, where he left it ten days later "in contented possession of

and ate oatmeal, bread and fruit.
