came by to talk about her viscacha (Lagidium) project. She works with Julietta von Thungen at INTA and with Dora Grigera and Carmen Ubeda in the ecology department of the Univ. Comahue. They have been trying to locate suitable colonies for study: Cullin Manzano, Valle Encantado, Perner's cinder block factory at Dina Huapi, and now they are thinking of Pichi Leufu. So far the amount of profitable field observations seems to have been negligible. Sra. Sbriller at INTA has at least identified plant fragments in droppings; mostly grasses. In the evening went to a SNAP meeting which ended up as a travelogue for Copan, Tical, and Ecuador. November 28.- Bariloche. Temp 58, clear, then clouded up in afternoon. Went up to Refugio Neumeyer in Chalhuaco. The floor of the lenga forest in many places has thousands of seedlings coming up- just the two cotyledon leaves so far, but they may well be lenga. Perhaps it was a good seed year and a good wet spring for sprouting. There is very little understory except scattered Ribes, Berberis, and, of course, amancay lilies. The floor is frequently "bare" except for the scum of fallen, plastered lenga leaves. The one clump of bamboo that we know of on the whole mountain, about 300 yards above the Refugio between the trail to the lakes and the stream to the left, was in bad shape. About half of the culms had been bitten off 2 or 3 feet above ground level, and remaining clumps of branches had been eaten almost down to the culm. Some of the lower nodes on some of the bitten-off culms were sending out shoots for new green branches. It looked like the work of hares. We found one clump of hare fur lying in the trail, and saw one hare in the nire scrub along the road on the way out, but did not see hare droppings. With 2 or 3 feet of snow on the ground, that single clump of bamboo might have been the only green thing edible for miles around. November 29.- Bariloche. Overcast, some drizzle until evening when it cleared. Talked with Adam Hajduk the archeologist. When he camped with Damiana Curzio near Cueva Traful III, there were so many mice that they ate holes in the tent and messed up the cooking supplies. The native with them set a teeter-totter water trap and caught many mice. Adam working in a rock shelter had a wild mouse come up to him and walk onto his outstretched hand. About 10 years ago; species unknown. He also had two mouse skins saved by Dolly Frey from her place across the lake (not La Lonha): one Chelemys and one Irenomys. There is lots of high country with big lengas. Name Paso Coihue. Went to Adrian's study area on the airport road at dark with Karin and Mariana with the night vision
