V. Memmler 1943 61 Journal June 4, Santiago Springs, 2700 ft., 8 mi. E + 1/2 mi. S Simister Slope. Californicus in my snap traps and 1 in my live trap. Otherwise I caught the following in my snap traps: 1 O Reithro- dontomys, 2 O + 2 q Peromyscus maniculatus. I brought my traps in since my catch seemed to be poor upon the hill. Last night Emma had good luck setting along the stream for pocket mice. So I set my traps along the stream tonight. This afternoon we set out to dig up a pocket mouse burro. The first trap set along the stream , not more than about 25 yds. from camp, had a hole near it. We could see a small animal in the hole so we decided to take it out. It was a young Peroquathus californicus with eyes still closed. Seth dug up the burro and in all found 3 living and 3 dead young. We have the young that are still alive in a box and I am trying to feed them in the hopes of keeping them alive. June 5, Last night I set out 48 live traps along the banks of the creek leading from Santiago Springs down toward Carrizo Plains. The water is piped from the spring now. Most of the water from the creek goes into the pipe, but there is some overflow for a fews 100 ft down
