1927 El Tablon, Lake Guija, Dept., Santa Ana, Salvador May 17-23, 1927 - From Volcano Santa Ana to San Salvador then back to Lake Guija. May 24, 1927 - This region is very much like the country around Divisaderos and many other sub-tropical stations that we have worked. I slung close to one hundred snap traps in some sub-tropical second growth back of camp. Here I found a knoll covered with large lava rocks and it was under these rocks that I set the traps so that they would not be sprung by the driving afternoon and evening rains. Part of these sets were made under large lava rocks along a ledge. This morning I had two Peromyscus Nos. 12954 and 12955 in the traps which were set on the bushy knoll. The ants had eaten the ears and nose off of one of these. There were three Liomyis, three of which were destroyed by ants. No. 12956 was caught on the ledge. Ants had eaten the oatmeal off of all the peddles. It rained yesterday afternoon and drizzled all night.
