mate. Says the Park is still shooting deer (3 species) on Isla Victoria and that the vegetation is recuperating nicely. In addition, they still have a few penned pudus, plus some released ones. Also on the island are volumes of handwritten notes on plant introductions back in the thirties: what species they tried, how well they grew, etc. Juliana and Claudio came by after we got back to Bariloche, and Mrs. La Rochet. December 7- Weather clear. Adrian Monjeau came by. He says he has trapped at Refugio Frey in the bunchgrass and lenga achaparrada and caught lots of Abrothrix, several Chelemys, one Geoxus, and 1 Oryzomys. He brought along the contents of a small pellet (or pellets) picked up along the trail from Frey to Punta Princesa; it contained several Auliscomys. We then went out to Llao Llao and ran a census of bamboo canes along a transect in the dense part, beginning near our arked plant on the Auxiliary trail December 8- Had planned to go to Castano Overo but some rain and low barometer, so we went down the Rio Limay to the Valle Encantado and hiked up to a cave visible from the road 4.7km south by road from Confluencia. It is at the base of a rock spire near another striking spire that is probably on the maps as "El Centinela". It is on the Bstancia Siete Condores, but in the "Reserve" portion of the Park. It took better than a half hour to climb up to it; it is about 700 ft. above the river. Very windy on the ridges, and sometimes the surface being blown off of the River. The cave is the size of a large room with a high ceiling, the floor is dry dusty dirt mixed with mouse bones, not at all stratified, no Indian paintings on the walls, although Peter found a human tooth. About 12 feet up on the back wall of the cave was another smaller cave, and in the back of it, dark enough to make a flashlight useful, was about a shoebox full of somewhat compressed mouse droppings fixed firmly to the back wall of the cave about 8 inches above the present floor, which was dusty dry dirt. There was some dark discoloration of the rock around where the mass was fastened. Nearby was another less-compacted mass, also stuck against the wall of the cave and covered with dust. We collected most of these two masses. Access to this upper cave was gained by two cipres trunks that had been propped up against the wall. It is hard to conceive of how mice gained access without the trunks. Possibly the floor of the cave had been much higher once and archeologists have dug it out. There was some fill outside the entrance. There were a couple of places where owls could have perched, including in the upper cave, and we collected various mouse bones that surely had been in pellets once but were now thoroughly dispersed. Saw no really fresh mouse droppings nor cuttings, but assorted reasonably recent mouse droppings were retrieved from various depressions in the rock. Unusually strong gusts of wind brought dust into the cave and blew mouse droppings around. We saw several large cipreses that had been blown over in recent
