P.V. Miller 1940 General Account He put up the hawks and ?the Raven. About 4 PM we went hunting. I collected a Pyrruloxia and Benson 3 Polioptila caerulea and a Cottontail Rabbit. We also shot a Jack-rabbit, which had an open wound in its side. We did not save it. It did not rain during the day but is still cloudy at night. March 27 We left camp in the morning, setting only 25 traps the last night and not putting any of the 'catch' (1 Peromyscus sp.) up. The side road was very muddy and we barely made the main road. We travelled to Monterrey, not seeing any good places to turn off and trap. We left the gray cloudy sky behind before reaching Monterrey. Benson saw the American Consul there, but there were not permits yet for us. We left soon, going a few miles to Catarina (still in Nuevo Leon). From here we took a dirt road S that soon led us into the river bottoms (The Pea River, I believe). We went about 1.5 miles S and then turned into a large dry canyon to the W. After about 1.5 miles up it we camped on the N side of a ridged "island" in the center of the canyon. Some gypsum pits were being worked here by 10 to 15 Mexicanos. They came up to visit us while their blasts were fired. Each of us set out 50 wooden mouse traps and ? set out also 10 no 1 Schuyler traps for rats or squirrels. (1?, +?)(no embryos) March 28 ?in my traps I collected 5 Peromyscus boylii. The night before ? and Benson shot a few bats including : (?shot 1 T. femorosaca, ?, no embryos) Tadarida femorosaca, T. mexicana and a Pipistrelle. During the day we put up specimens and collected birds.
