aye - (1933. French Gulch, 6200 ft., Piote Mts., - Oct. 30, 1933. and the meriamis to the pine-oak slope. Today, when I sneaked up on the scene, all the quads were mixed up in the fir slope only, and all the meriamis were in the pine- oak slope only. I chased, and saw several quads run into small holes in the base of the fir trees, while on the other slope, all the meriamis ran into ground holes under the rock ledges. So summarizing we may conclude that all the quadri- ittus live in holes in the base of fir trees, on fir slopes only; and that the meriamis live in the pine-oak slopes, for the most part in the rocks and under ledge. Further they apparently mix, and forage together in the boundary line between the habitats. Now might arise the question as to whether or not there is any inter- breeding. Science would say there could be, but that there would not be any persistence of the offspring. Apparently these chipmunks do inter- breed. I shot an interbred this morning, and seemingly enough I shot him off,
