V. Memmler 42. Itinerary April 8, muddy creek 1000 ft., 1 mi. S Clover Canyon, Monterey C, Calif. Ringlet and Linnet songs during our walk. The Crowa mentioned before ever seen again. Mrs. Grinnell caught 3 Salamanders today all under the same log. April 9, Last evening Jean Boulware and I set out 127 traps along the wood road starting from the flat and going eastward. Salvia mellifera, Artemesia, Baccharis and Rosa are the main plants in the habitat in order of dominance. Short grass is growing under the bushes which are from 3 to 7 ft. tall. The Soil is fine gravel and sand. We set in runs as much as possible this time trying to get Microtus as we have given up hope of getting Dipodomys here. There are runs of very small diameter in great abundance and since we caught mostly Reithrodonomys today we believe that these are their runs. We caught 13 ♂ and 6 ♀ Reithros, no embryos; 2 ♀ and 10 ♂ Peromyscus maniculatus; 1 ♂ and 1 ♀ Microtus with 5 embus. 18mm and one ♂ Sorex. There were 14 traps sprung without catch and the bait was gone from 4 unsprung traps. There were a few drops of rain during the night and a sudden shower this morning. There have been frequent showers this afternoon. Mrs. Grinnell, Jean and I went hunting Barn Owl Pellets two
