Lee Arnold 1937 Neotoma cinerea #2. May 29 Horse Canyon, 5,800 ft., Pahrum Pk., Washoe Co., Nevada. Last night I set several traps in the mine which seemed to be the most used. I was surprised to catch only one almost adult ?. The four other traps set at the end of the mine were untouched. Could it be that this single rat was responsible for all the clippings and the three nests found nearby. Or could it be that the others, seeing the fate of this one, became more wary and were content to eat what food they themselves had gathered. In one mine where the bottom was full of water there was evidence of the rats having traveled along the narrow ledges of protruding rock on the sides of the cave.
