July 2 Columbia R, 300 ft at mouth of Deschutes R. Sherman Co., Ore.
Made some gopher sets in the now abandoned fields (but formerly garden truck) of a ranch across the river from the base immediately after setting camp. I'm going over the traps, found I had caught 1 & specimen already.
July 3 Caught 2 more gophers in my sets this morning. It had rained enough during the night to moisten the ground. I believe this increased the chance of catching gophers in this field, as the moisture probably aided in moving this clay-like soil which packs very hard on drying. The traps were reset and by evening had 2 more gophers from the same locality as of July 2.
July 18 Paterson, 250 ft., Benton Co., Wash.
While setting mouse traps last P.M. dug open a gopher burrow. On returning a half hour later, noticed the gopher had filled the opening. Set a gopher trap in this burrow and this morning had a female, which was still alive and apparently hadn't been caught long. Thus it seems that it left the burrow open all night, after I reopened it to set the trap. Prior, it closed the opening immediately (daylight).
