Pearson 1977 Argentina 4 locetres Left near for south on the road past Joke Maccardi and Giulino. The full colors of lenpa are gorgeous, a few red-brown cottonwoods gorgeous, n. antarctica dull yellow brown. Bonbardy yellow Poplars have lost their leaves. Camped along a stream between Foyel and San Pelelos, fairly arid, with cypress and lenpa along the stream; sorberry, retama, cypress, and marten on the flats away from the stream. Shot about 28 museum specials along the stream (under roots, boarders, etc). Anita put 33 in the flats; just before dusk 2 teen-age fishermen worked their way downstream past camp (and past my trap lines). Then they returned upstream and I caught them stealing 2 traps; rewarded tthem. April 26 Night mostly overcast, but lightly. I caught much, never dropped below 56°, 60° at dawn. My traps held 8 Oryzomyz longi (released 2 of them), 3 Akodon longipilis, and 1 groove-toothed Phyllotis with long tail! Anita had 9 Oryz (2 discarded), 2 Phyllotis micripus (oneg's), one Akodon sp., 6 Akodon longipilis, and one ? Discarded the following: Oryz.longi W.A.
