D. J. Hoffmeister 1939 Itinerary July 4 Columbia R., 300 ft., at mouth of Deschutes R., Wasco Co., Ore. Last night, I set out 23 traps, one of which was a rat trap. About half of these I set on the side of a railroad fill, consisting of a small sand-gravel mixture. There seemed to be abundant Dipodomys sigaus around, and Johnson reported seeing them in this region also. I caught no Dipodomys here although about 50% of the traps were sprung. In all, I got 5 Peromyscus maniculatus (4♂, 1♀), and 1 Neognathus parvus ♀. Last night we also watched for bats. The first we saw at approximately 8:30 P.M., and Johnson thought it was a Pipistrellus. Between this time and 9:00 P.M., I only saw 2 other bats and these were at considerable distance. July 5 Set 20 traps along the railroad tracks near the mouth of the Deschutes river, where it follows south along the river. In the 20 traps, caught 4 Peromyscus maniculatus (1♂, 3♀). Considerable of this region trapped in looked like good Dipodomys country and also Neognathus. However I caught neither. I picked up the 2 no. 1½ single spring steel traps set by Johnson and got one
