trunks and bamboo clutter along the sides. Good cover. The lenga leaves are well out, dandelions blooming, green grass in the meadow, cacho de cabra, and a few lilies well up. One patch of snow about 3 m in diameter, but everything pretty dry. The marked bamboo clumps have almost no yearling shoots, hence poor reproduction last summer. I put out 22 Shermans and 22 Museum Specials, alternating, rolled oats in the Shermans and corn meal on the MS. This is almost the same line as last year, except this year no traps below the road. Anita put 22 Shermans and 22 MS in similar habitat. She caught one Abrothrix while she was still setting. October 18 - Morning clear, night warm. Went up to Cerroí Otto at 7:30 a.m.. Anita’s line had 4 longipilis and 1 Auliscomys, all alive. I had 4 longi and 1 Aulisco. Two of the longis were in Museum Specials and the Aulisco, but I lost one of the longis on the way home (it was a female). Measured altitudes from the street in front of our house (2680 ft) to bamboo clump A@ on Cerro Otto (3790 ft) to the top of my trap line near the road (3900 ft). This makes the trap line from 1150m (bamboo clump 1158m) to 1180m. Processed mice. Saw Arturo Tarak, Marcelo Bettinelli, Christies etc. Earthquake in San Francisco. October 19 - Went to La Veranada and measured the bamboo clumps. Road still not paved, and the big equipment was working right up at the divide. Everything pushed around near our old campsight and the grid. Culverts e tc. hqave changed the drainage, but various streams still running. The meadow sort of green but very few dandelions, and everything quite dry. The nire just beginning to put out leaves. Put out 6 Shermans at one good spot when we arrived. Wehn we left, maybe 4 hrs later, had one female longipilis On the way down the hill, pulled off to the east at the south end of Lago Guillermo on a dirt road that goes into nire/bamboo near a big meadow at the end of the paved road. These nire also just leafing out. Very dense, small-leafed bamboo here, both the bamboo and the nire somewhat bigger and lusher than up above La Veranada. We were creeping along a narrow path in the bamboo, thinking we were away for everyone, when we practically bumped into Parkguard Flavio. He lives in the ranger cabin at La Veranada and had walked downstream to Lake Guillermo and was on his way back up. He has been here 6 months. He says that in hard winters they bring the horses from La Veranada down to here to graze, but since there was not much snow last winter, they didn’t do so this year and for this reason the grass down here was dense and lush, ungrazed, and the bamboo was ungrazed also. Back to Bariloche 6:30 p.m. Day was warm and sunny. October 20- Bariloche. Sunny and warm all day. Processed mice. Spectacular vaginal anatomy in Abrothrix. Juliana, Christie’s former secretary, came; says lots of mice at her place along Lago Mascardi. She says Akodon
