a hundred yards or so further a large dump left rises along right side of road. Climb this to find extensive tunnel system.] In this tunnel we counted 24 Cory and 1 Epleorus, all torpid. Did not disturb them. Then drove a few-hundred yards further up road and entered another tunnel to left of road (2 Cory), then followed up to right, parked, and walked over crest to any tunnel north of the main rock dump. Found 39 bats in this one - all Cory, all torpid. Then dt. supper back at car and returned to my tunnel to sleep (7 p.m.) in view of cluster of Cory. This was the largest cluster (5) seen - almost all the rest were singles. One by one 4 of these 5 flew, as well as 2 others visible from our sleeping bag. But a few bats flying early in the evening, not many later. Can't say how much of their activity was due to our disturbance. They seemed reluctantly fly over our sleeping bag when we had a faint green light on (flashlight covered by 6 layers of green cellophane). Some made quite a fluttering sound while flying, other completely silent - perhaps depending on how fully awake they were. Dec 20 One female of original cluster of 5 Cory remained in same place. Another cluster of 4 had formed eleewhere in tunnel, and one pair [a D or look of a q, both torpid, female with large drop of fresh fluid apparent from vagina]. Collected all bats
