pounced but he got away under the thorns. Tonight a coon has been settng off my traps under a cement bridge. The traps are on a little foot-wide cement ledge with mouse + shrew droppings. He checked a little while ago & there were the coons big wet footprints. Aug. 13, 1949 Maple Creek, Humboldt Co., Calif. Moriella: 9 Pers /100 mixed traps /S. pacificus (?) Dne: 8 Pers. 65 snaps 3. Sons Pacificus (?) 1 Zapus 1 Miroles oregoni (?) After much debate about the microtine we have decided it is probably an M. Oregoni. It was a pregnant ?, but the feature that bothered us was that it had 6 plantar tubercles instead of the expected 5 - the sixth was quite small but definite - as in some of the M. Californicus. One thing we are impressed with among the Sons Pacificus is that of all the ?? we have caught, none have been pregnant, but practically all have lots of mammary tissue. Moriella has caught 2 Peropecos in her snap traps during the day time. About noon (in the morning he strained) we set the other 50+ live traps out upstream, stopping for a swim & sunbath on the way back
