archology evening at the chalet 4 km west of town (owned by an Deftification officer). Lots of droppings at what appears to be a night roost, and a hole in a beam where the caretaker says bats emerge. Oct.29 night clear + cold. In the morning I looked at the net at the night - roosting corner of the house, but none in the net covering the north porch where bats were said to emerge from a beam. Shopping, drove to Elao-Elao and cut for some Chusquea canes for bat poles. Returned to the Archology house in the evening, tidied the nets, and waited for bats to ermerge. Some were flying but saw none emerge. Overnight, temp. about 56° F. The caretaker of the house says bats are present winter & summer, but more abundant in summer. Oct.30 morning clear, temp. °C, two myxies in the night - roof net. Caretaker says they were caught after midnight. Coffee with Wm. and Hilda Rumboff, 3 1/2 km W Bariloche. She has seen Sasmurus here, feeds hummingbirds (2 species), and says the hummers are present winter & summer. People take torpid hummers to a taxidermist friend of hers. Lunch with Rafaporto, then out to Hotel Gog Moreno, near Elao-Elao, turnoff at 20 km. The garage at the hotel had a good bat atlie, one torpid & myxotis at 4 p.m. (air maybe 6°), and lots of droppings. Informant that says bats are present winter and summer, has seen a group of them torpid, feed down, when he pulled boards off the side of a house (the Elao-Elao Hotel, I think). Snow here settles as much as 200/30 cm. There is a sharpcline of rainfall from 500mm at the Bariloche airport to 1000 mm at the town to >1500 mm in the mountains to the east,
