torpid and one ♀. More fat. Took aware of ♂♂, but no signs of mating. [Kept all bats caught]. How can we keep catching unbanded ♀♀ at Astra Mines where we have banded so many young ? Where are the missing males? Found an unbanded baby mummified in the Margarita Tunnel. May mean that this is a roost for the nursery colonies that was in the 20-House Hole last spring. Seems interesting that no bats in the 2 best winter tunnels: Catbunka and O.P. Forgot to mention that about 2 Cory escaped from the abyss branch of the 20-House Hole and one from the short tunnel on the south face of the 20-House Hole near where the RR track enter. Also there were 20+ Eptelina? in a high croke just across the abyss. Home about 4 p.m. nov. 15 Put 7 Cory in zoo cold room (42° F). These are ones cought Sept. 16 and 17 at Astra and Manhattan and fettered up at home isolated from males. nov. 18 left 1 p.m. with Anita & Carol for Marin Co. Running. looked in 2 tunnels at end of Oak St. in San Ansalevo (Bald Mtin.). Good tunnels but no bats. Looked in, old R.R. tunnel near fire station in Woodacre. This tunnel is about 1/2 mile long, timbered with wood ceiling, dark and drafty. No bats seen although may have been many between board ceiling and roof of tunnel. Seemed like a good place
