35 Barranca de Metloc, 3250ft., Veneruz, Mexico May 10 from the power plant. There is a rest-room adjacent to the picnic area, a small swimming pool, and a covered dining area with electric lights. The Rio Metloc is about 75 yds wide and flows rapidly over a stony bed just 50 yds from our camp. The barranca is narrow with just room for road and a few banana trees at the side of the river before the steep slope of the side. The Mexico-Venezuela railroad circles the barranca 100-200 feet up on the slopes. Water for the power plant comes from a dam at a point near Sunideros and drops 400 feet to the plant, then flows into the Rio Metloc. High on the slopes, just be- low the railroad tracks there is a line of tall, epiphyte- coved trees but below these the slope is planted with coffee and bananas. Also there are banana and coffee trees in the narrow flat along the river. Sr. Ralago said that there is a more or less constant mist in the canyon and that it is never very hot in the canyon. Sr. Ralago recalls a man and woman camping here a few years ago to collect mammals - probably Dalquest and his wife from Kansas. He also mentioned a man camping here to collect mosquitoes - but he cannot recall the name.
