1927 P.25 Los Eses miles, Dept, Chalatenango, Salvador February 17, 1927 - Today I took my trapline far over on the north mountains slope into a heavily vegetated canyon where a small stream, every few feet fed by more springs, flowed off to the north and east. The vegetation along this water course was so dense that I had to cut my way with a machete. I started my sets at the lower edge of the oaks in the canyon and followed the stream downward for perhaps a quarter of a mile, especially making feet for Rheomys and Cryptotis. Some traps were placed under logs and likely places for other mice and rats. There were signs of Cuniculus and Dasypocta along the stream course. Other snap traps were set among trees along the canyon slope at a lower altitude. These traps were placed under logs and in runs through the moss. Sylvilagus No. 12539, was brought into camp today. Their dogs ran it into a hole. Reithrodontoms, No.12540, was caught in our house, and Sciurus deppei, No.12541, was shot in the oak rain forest by our native helper.
