Journal 9 March 1973 Nat'l Park Guatopo, Venezuela cut in a "rocuro" tree 3' diam. with straight hole, which had milky latex which tasted like thin cream; he made 1" hole in bark & the milk started to bubble down trailer, slightly sticky. Said a good drink. Only about 3 old slashes on tree. / At one point picked up a possum skull, probably Didelphis, but we saw no other animal remains. A few deer tracks. Four trees in bloom, but many fallen fruits & seeds (green foods?). Last part of trail about Rio Santa Cruz a mile, descending, to a clear stream about 15' wide. Chis cut quite a bit here. Said cursed for about 6 years. We saw almost pair of guans, searched about 200' away quickly - seemed to indicate little disturbance. Bloody blue face, red gular patch. Small fish (4") + crawfish (3" across) in stream. Said to be old trail complete nearby. / With brief stops for water, lunch, it took us 5 1/2 hrs. to reach end of trail. Start time about 1330 & moved faster, so saw little. Back at starting point about 1730. Chis had found a small geyser on rock at side clear stream; it ran across water about a foot. Let us put it in sink of water it could indeed go across top, but mostly not breaking surface spec. tension, likely perhaps acting as float. We also picked up frog leg from trail in hard forest; cream colored 1mm. line tips more to tail; pointed Kote: nose. / Day morning, dried strips gave - We all picked up numbers of tiny ticks, especially around ankles & belt. / Chis said there were sloths here (one kind) but we saw none. Fair numbers of bats seen in evening near buildings. The pineapine dropping also had apparent snake scales; saved sample - and 2 nematodes. 10 March 1973, Saturday. Talked w/ Escalona & looked at map. Walk yet: day started about 1 km. before Macanillares station. Went w. to File El
