1927 El Tablon, Lake Guija, Dept, Santa Ana, Salvador May 25, 1927- Today I ran a trapline in another section. This place was known by the native as "Mal Payes" or bad country. The vegetation was thick and fairly heavy but due to sharp lava rocks all through the region no people occupied the ground for agricultural purposes. This flow of lava obviously did not come from a crater but from what might have been called blow holes. I crawled down in one of these more or less crater like holes where I used a flashlight to light my way. There in the cracks and crevices I saw a colony of at least thirty vampires [illegible] both old and young. They hopped about for dark corners when my light was turned on them. There were no other species there. I followed the trail farther into the more dense jungle. The lava rocks were thick and, now, they gnawed away at my foot. I at last came upon a ledge which projected up from the sub light about forty feet.
