1927 R.17. Barra de Santiago, Tepy, Ahuachapan, Salvador tangled mass of second growth vines and brush. Ants are thick in this region and it is very difficult to trap small mammals. As one breaks away from the trail and follows narrow paths toward the west, the colol palms become denser and thicker. Frequently agoutis are heard as they become frightened and go barking and snorting off through the brush. Suddenly one runs onto [illegible] fresh water streams (called sweet water by the natives). Here the soft sticky mud is found again. The trees are not so large or so thick as in the more arid region, but in the swamp are large rosin-like weeds that are so dense and heavy that one has to cut his way with a machete. Under these weeds are pig, raccoon, and agouti tracks a plenty. This was where we saw so many wood rail tracks. April 20 - 21, 1927 Morning.
