Pearson 1947 3 Spent much of the day shuning water skrews, Nearly blew a fuse thinking of the time going into Lorenz n+1 to enlarge an already lengthy series while 90% of my catch was rotting in the sun, never to be looked at even. Benson's theory seems to be that Microtus etc. reproduce all right without my worrying about their reproduction, and that we will never get anywhere studying the microfauna of the Sweetwaters if I spend all my time looking for scent glands etc. At least that was the gist of yesterday's discussion. Today I am a yes-man and advance Science by putting up on Lorenz palustris coward- but not coward or converted. July 23 Temp. 36° before swamp, and some ice on grass overhanging stream. The original 35-trap line caught 2 Microtus montana, 5 Pruisens, and 1 Zapun. Picked up the original line trap line in which were only 2 Pruisens. The 49-trap line along the sweet stream had 8 Pruisens, 3 Microtus longicaudus, 3 M montana, 2 Zapuns, and 2 Sorex palustris in the morning, and 2 more Sorex palustris in the late afternoon. The chipmunks line traps in the morning were as follows: 19 in grass - 3 Pruisens and 1 Logurus, 19 in artumezia - 2 Entumas and 1 Pruisens. 44 in scrubbing - 4 Pruisens. Also shot some
