1927 P.5 Hacienda Zapolitan, Dept. Libertad, Salvador and got the dope. One was caught in a small round hole (6in. in diameter) in the banks about two feet from the water. This hole looked as if it was being used but the rains had washed away all tracks. There were some water soaked sticks and trash that looked as if they had been partly dragged into the hole. A well worn trail led from the hole down the bank to the water. Another was cought on the root of a large tree that stood on the very edge of the river banks. The root on which the opossum was taken extended down to the water. [illegible] I had to chip out part of the root to partly conceal my trap. Faeces containing fish bones and scales, that I saw on the root caused me to make this set. The third was set on a little ledge between two roots and about two inches under the water. This set appeared as a likely landing place.
