Wolfson 1938 July 13, (cont.) 51. 1/6 mi S, 3 mi E Lostine, 5500 ft, Wallowa Co., Ore. ground cover was pure needles almost exclusively with few herbaceous plants and growthy but dead logs large and small were abundant. A small stream ran thru one corner of the area. About 50 traps were set here, and about 1/2 mile was covered. We then returned to the bridge and started another trap line along the Lostine R. The line began a few hundred yards N of the bridge and ran about 1 mile to the S. The forest was of the type previously described, and part of the area was previously trapped (July 9) Three gopher sets were made, and about 50 traps were set along this line. It was not a continuous line but broken up three times with large distances over "poor" trapping areas. On the afternoon the rat traps and 1 remaining gopher set were examined. Nothing caught - all traps brought back to camp. July 14: Left camp at 7:00 a. m. to examine mouse traps. Examined the 1st line and had caught 4 Clethrionomys. All were caught near or beside
