9/9/25 32 and not more than sixty feet from (10422) the places where I caught two blue-tailed (10442) rats and two Peromyscus. In the stomach (10433) of the peromyscus that I caught today (10436) I found some brown seed pulp and some material that looked very much like insect remains. This location that I have been speaking of as a rocky lake shore in the edge of the jungle is on the north east side of the lake near our camp. The lake's shore is at the base of a rocky jungled ridge. Just above the high water line and a cow trail that follows the edge of the jungle I set my traps in crevices, and under protected shelves of the rocks, and in places where small holes led down under the rocks. Some of the rocks are loose and some are half buried. On the north side of the lake near the lagoons of the San Miguel in a small grove of collol palms I (10437) caught an opossum (Didelphis). This trap which was set in a hole that led down under the roots was tripped for three consecutive mornings. When I set three traps there in a V shape I caught the specimen. I shot another (10438) female brown mastiff bat near camp at dusk. September 10, 1925 - I caught (10439) another spiny-pocket mouse by a small round hole that led nearly straight down. The water from the lake spread over the grassy patch at the south side of the lake so I had to remove my traps from (10441) that place. I shot another male brown mastiff bat.
