Thacker 1956 Pg 27 journal July 18 mountaineer mine to indio, san bernardino co., calif. there were some small bats beginning to fly, probably Pipistrells. We picked up our remaining equipment and proceeded to the car. After driving out to the main road we transferred the bats to cages. Many of the Macrotus had died. Beck banded and released a few. We drove on to Vidal Junction, ate dinner and then drove west to indio and got a motel about 1 A.M. July 19 Indio to Mountaineer Mine, Riverside Co., Calif. When we got up about 7 A.M. we found most of the Macrotus dead. Also many of the Myotis velliifer had died. Beck wanted to investigate reports he had received about large roosts of free tail bats at the USDA Data station here. After breakfast we went out there but found no roosts that were currently being used. Since the main purpose of Beck's trip was to secure live bats for experimental work he felt he should make another attempt to secure Macrotus. We now had only about 5 left alive. I saved most of the dead ones plus some M. velliifer to put up. We returned to the mountaineer mine, arriving about 2 P.M. This time we carried in cages to put the bats in rather than use sacks. We hoped this would cut down on the number of deaths. We went through both mines but with little success. Most of the Myotis had moved to areas of the mine we couldn't reach or
