doubtless hardly covered with dirt as they go. I suppose they find the insects in the leaf-mold under the thickets here and there. Lamb and I both have "modified" Macabee gofer (sic) traps set all the time for the moles, but this species is so small that an individual goes thru and thru (sic) a trap without springing it, or if sprung, without nipping(?) him. 7:00 p.m. -- Barometer = 23.20 inches Sky partly overcast, but northwest wind blowing cold. 6466 Merriam Chipmunk (male sign) 56g. 226x98x34x14.

The taking of an adult White-crowned Sparrow today, with brown-crowned immatures in the vicinity, brings doubt as to the identity of the considerable numbers of zonotrichias here -- since an adult Intermediate (gambeli) was also taken. I was under the impression all were of the latter race until today. Saw at least 3 Tanagers (Western) today, in cascara bushes; also 3 Solitaires, and tonight heard the "creak" note. Bluebirds are as numerous as ever, possibly more so; and there is the chance now that northern "occidentalis"(?) have come in, along with such winter visitants as solitaires and Sierra juncos. 6480 Eutamias merriami (female sign) 58.2g. 232x99x35x15} in rat traps 6481 Eutamias merriami (female sign) 60.4. 223x100x33x14} at boulders 6482 Eutamias merriami (female sign) 67.4. 228x100x35x14} and cascara bushes. 6483 Solitaire (female sign) im. 37.2g., fat.

Shot in cascara bush. 5 p.m. Our packer, José, has just come in to inform us that a mule is missing, so we will be two days late in changing location. But - "mañana" is the rule in this country! The feature of my day was a full close view of a Ferruginous Rough-leg (my gun was entirely out of commission at the moment!). The bird circled above me within 60 yards, showing its character well. It was the whitest hawk I ever saw. The whole under surface was white, save for sparse dark markings on the chest; The basal 2/3 of the tail was white, the terminal third being light dusky?; The under sides of the wings were white save for dark primary types and for dark mottlings in a transverse row at "wrist." Lamb and I have both seen this bird distantly in previous days, referring to it as "the white hawk." This is the only other buteonine besides the Red-Tails we have seen at this station. Saw a Great Horned Owl fly along the hillside at late dusk last evening. We hear their notes every night.

Discarded: 3 Peromyscus truei, 2(female sign female sign), 1 ( male sign); one of these at same wood-rat's nest as no. 6514, others under edges of boulders with manzanita and scrubby oaks about. Today, 7:20 to 12:20, I took a strenuous walk about 5 miles due east to the jumping-off place, in other words to the eastern rim of the San Pedro Martir plateau. I went up the Arroya La Encantada to the big main "meadow" (now just weeds -- the tall slender composite with inconspicuous flowers, sample saved from near camp); then off along the eastern arm of this flat and up a draw over a divide at, I think, about 8000 feet, and down into the head of El Cajon Canyon which makes down precipitously onto the San Felipe Desert. I climbed a hill and got a fine view east, across the San Felipe desert, then the San Felipe range of desert mountains, then a further strip of desert, and then the gulf, beyond which I could

see in very faint outline the mountains of Sonora. The panorama reminded me strongly of that seen from the Santa Rosa or San Jacinto mountains of southern California eastward. Toward the top of the divide the prevailing Jeffrey pines were mixed with some white fir, incense cedar and sugar pine; and in the rough hills adjoining the pass were numerous scrubby oaks, and rather dense chaparral of manzanita, buckthorn, and cascara. It was here, on the dessert slope of the divide, that I encountered the three Calif. Jays. The following census was pencil checked on card-board on the way out, from camp to my farthest point over the divide, 7:20 to 10:00. Pigmy Nuthatch 68; Audubon Warbler 5 (only along the stream); Bluebird 10; Cabanis Woodpecker 6; Townsend Junco 13; Chickadee 10; Raven 5; Red-tailed Hawk 2; Pinyon Jay 1 (heard); Olive-backed Thrush (1, in cascara bush); Canyon Wren 2; Williamson Sapsucker 1; Slender-billed Nuthatch 4; Red-shafted Flicker 1; Spurred Towhee 1; Siskin 5; Calif. Jay 3. Total, 17 species, 138 individuals, in 2 2/3 hours. Note that just about half of all the birds noted were Pigmy Nuthatches! Of mammals I checked in the same period; Chipmunk 28;Scirus 2 (in pine near divide); Wildcat (one out in open meadow in bight sunshine; bounded up a draw; may have been laying for birds coming to drink at the seepage near where he was); on the way down
