Redstone 1945 Journal 63. Nov. 18. Alameda & Santa Clara Counties, California Left Berkeley shortly after 10 AM with M. Ramage, and W. & M. Fox. Drove to Mission San Jose where we looked in the Mission for Corynorhinus. These bats evidently roost in the darkest part of the attic (the NE part) but hang up at night in the more open south end. The mission has a new roof - tile facing the front & shingles behind. The roof does not follow the con design of the old one being 6' higher & the ridge pole is about 6' feet farther back. It seems probable that the bats have left for the winter. From here we drove to New Almaden in Santa Clara County & up on the ridge to the north - about a mile (bee-line) from the town. Here there was a Hg. mine & we investigated two horizontal shafts, one where the road falls just before you get to the mining community and one a short distance to the north along the other forks. The former yielded no bats & we saw no signs of them but the other had one Myotis (which I caught in a net) and numerous small piles of droppings under small devices in the ceiling of the shaft. There were few places in the shaft which could not be reached by one's hands and it looked as though several other small bats had recently been in the mine shaft. We left here about 2:45 PM and
