adult. A fox barked close around campsite in the middle of the night. Left for Bariloche at 10:30am. Measured kilometers as follows: Arroyo Carbon to the sociabilis site 20.4 km; to the Villa Angostura turnoff 30.0, and to the bridge over the Limay at Nahuel Huapi 32.9. Hence Arroyo Carbon is 32.9km by road N of Nahuel Huapi, call it 30km N. April 20. Michael Christie came by with another specimen of Buneomys; then Patricia Fierro. Caged the live Akodon. April 21. Adrian came by to arrange a lecture date. Left at 3:30 for La Veranada. Cloudy and sprinkly. Still working on the road, no visible progress. The bulldozing has prevented access to our regular campsite across the road from the grid, but one can still drive off into the nire scrub a couple of hundred meters north of the campsite. mThe nires just beginning to turn color; did not see our bamboo clump on the road shoulder. Put out 26 bigt Sher mans baited with oats along a path through the nire/bamboo/berberis clumps. Then along the same line put out 9 steel traps, all in excavated tuco sets. These are the tucos that we have wondered about before, living in little clearings in the nire/bamboo, sometimes piling up dirt around the roots of the nires to make considerable little hills. Frequently there are clusters of up to a dozen feeding holes, mostly plugged but not all. Good open tunnels down a foot or so. Drizzle stopped about sunset. April 22. La Veranada. Scattered clouds overnight and some drizzle. Morning and all day overcast with some drizzle. The 9 steel traps had 3 tucos, the 26 Shermans had 1 Akodon olivaceus, 5 Akodon longipilis, and 1 adult Chelems. At 10 a.m. put out 13 cage traps. During considerable snooping around during the day, saw only three fresh tuco diggings, and I heard none. In fact, I don't recall ever hearing tucos in this area. Lots of strawberry and in the tuco clearings a compositae? ground cover with small leaves like arbutus. April 23. Heard barn owl and maybe screech owl during the night. Morning overcast, no frost. A little early for autumn colors. 26 Sher mans and 12 cage traps had 10 Ako longi and 1 Auliscomys. Nothing more in the 9 steel traps, all still in the same places in tuco burrows. Still no tuco vocalizations. A fox had scented a couple of the traps and moved one of them. The most successful longipilis sets seem to have been at dense columns with bamboo. Mixed flocks of Pygarrhichas and Aphrastura and ?others working through the nire trees. Home at 2:30 p.m., still cloudy. Christie came in evening. April 24. Morning cloudy but soon cleared; sunny rest of day. Cleaned traps and cages, worked on History MS. April 25. Bariloche. Morning clear but then clouded up. Frost. Yellow jackets were flying from their nest in the the shady side of the wall into air 4%C. A second nest is in the same wall only 15 feet away. They are not working
