on slopes or to south, next colony about 2 miles north. April 11 Washed dirt off vegetation sample in river at Cholojuba. Didn't know what to do with little dead leaves + shrubs that floated to surface, so discarded them. This problem was not encountered with the "corote" from the Tutuyupa samples. In the washing very few lost as much as 5%, of living roots & leaves some dirt remains for further softening + washing April 14 Further washing of plant sample in river below Jogo Dudo. Lost more dead leaves and probably some living roots. Total loss of living material maybe about 15% in form of roots left in situ, and washing losses. Washed sample is now stored in oven to dry. April 24 After sun-drying the plant sample weighed 527 gms. April 25 Returned at 5:15 a.m. to our Lichuyichuni census area.

Previously I had never seen more than 2 guinea pigs on the area at any one time (and those near the end of our duration), and didn't think more than 2 lived on the area, possibly more. This morning I saw 10 at once not think at least that many were living on the area. Some were only 1/3 rd grown, probably only a week or 2 old.

May be a few jokers too, since those are very hard to see (but could lend if present). The 2 baby were shot at a point where we knew one adult remained 18 days ago, so the invasion from family populated surrounding area in 18
