Hoffmeister 1939 Bats Dec.3(cont.) Berkeley, Calif. Time with regard to darkness, I would expect them to begin making a noise. Dec.5 5:40 P.M. Heard no bats & it was too dark at this time to see any but very quite sure none were flying out. Dec.6 5:20 P.M. Saw or heard no bats. It has sprinkled some during the day. Dec.8 6:15 P.M. Thought I heard a bat as did Fred Test also 1 block north (Durant & Dana) of the church were the bats roost. Heard none at the church. Dec.10 5:15 P.M. Was quite sure I heard some bats squeaking in the tower at this time, but when stopped & listened for about 3 minutes with Fred Test & my wife heard no further sound. It has been raining all day, is cold, & very windy.
