April 17-1932. Mine [illegible] miles east of Pocatello, I hurried out about 4 P.M. to collect some bats for class observation in Biology school work. My last visit here had been on Feb. 14 when 10 Corynorhinos and 4 Myotis had been observed in 3 different tunnels. I did not visit No. 1 tunnel where one Myotis had been previously noted. I found only two Corynorhinos in No. 2. They were collected alive. #3 Tunnel, where 1 Corynorhinos and 2 Myotis had been noted on Feb. 14, no bats of either sort were found. This tunnel is more often visited by boys from town than any other tunnel around the countryside, and although one cannot be sure, it is more probable that these individuals spotted here 2 months before, had been raided or killed by boys, rather than withdrawn of their own accord -- all of them.
