Dec. 5 Peulla. Morning overcast; began raining about 11:30 a.m. My traps had only 1 Gecina and 1 also oliv. Anita left the canyon in rain and along the stream caught 1 also longi and 1 also oliv. At the edge of the mallin she caught 3 also oliv (2 of them slug eater), and 1 mouse in a steel trap. Nice dark brown, wild-type pelt, caught by front foot. Released it. Peter resumes (about 65 museum specials up the canyon) caught 4 also oliv. Dagoberto Muller, the Parkward, says that 20 yrs ago the foot arch used to be right at the lake? (now a sedge marsh with iris). Then it was moved north, abandoned, and moved again to its present location all because of sedimentation from Trowder. He also says that there used to be carpers in the marsh but that now they are gone. Clears ups about 3 pm. Relented traps at 4 pm, using mouse grease in the coy traps and Anita put mouse grease in some of her Sherman's. A few feet from where the mouse was caught was a pile of mule-sized droppings containing almost entirely fragments of crustacean shell. Dec. 6 Morning clear, temp. 9°. My traps held 3 also longi. Nothing touched the mouse carcass left there. Peter caught 1 also longi and 1 also oliv., Anita caught 1 fadsting Rhyncholester in a quail/log trap in a m.s.
