Left our Payne Creek P.O. camp about 8 a.m. and proceeded on up the "Lassen Volcanic Highway", now in excellent shape. Arrived at Mineral about 10 a.m., and made our permanent camp, inside the fence which protects the "National Forest Camp-ground" from cattle. This is about 1/2 mile above (northeast of) the present postoffice and store called Mineral, and that far off the new thorough highway, which goes east to Morgan, Westwood, Susanville, etc. Our campsite is ideal - wonderful dryish slope beneath silver and red firs, ceanothus chaparral adjacent, a spring of cold clean water handy, and the edge of the Battle Creek Meadows within a few minutes' walk. The water in the various streams which meander thru the pastures is not safely drinkable. The abundance of birds in full song is bewildering. First impression is that never in any locality (unless the Colorado River bottom in May) have I encountered more plentiful bird life. Saw a family of bob-tailed young Juncos already out, despite the tardiness of the season (it snowed here a week ago according to the people at the store). Splendidly clean and warm here now, though. June 13, 1925. Joseph Dixon and family came up yesterday, too, and are camped close by. Spent the

feet up behind a curled up section of thin bark on a dead lodgepole pine of about 10 inches diameter; mounds of snow all about; adjacent trees, hemlocks and red firs. Bird comes with bill-full of insects, and I can see the usual mass of twigs under the open side of the lifted park. 2:45 p.m. - At about 7500 ft. alt.; off the trail to the west, in one of the heads of Martin Creek; a ledge of rock along the western wall of the canyon has broken off to form a long talus slide, rocks up to a yard or more in diameter. Here, as I hoped, I hear conies in the typical association for them. At the fast of the Talus apron the snow is just going, but a little grass is coming up; also among the lowermost rocks some stalks of red elderberry are showing leaf; out from the Talus are mats of the prostrate arctostaphylos nevadensis; up along the ledges I can see clumps of red cherry and chinquapin; the trees about are red fir. I hear a Rock Wren singing ventriloquially from the rim-rock, which is well provided with crevices and caverns. This may prove to be the westernmost station for conies in the Lassen "section." 3:50 p.m. - Down to about 600-foot level, having come thru willowy meadows, with the grass barely above the earth, yet bands of restless cattle already run onto them, to keep them grazed and trampled down and the willows browsed up to 5 feet or so, and no chance for young shoots to start.

and the structure is ensconced in a tangle of dead twiggery in part supported by slanting ceanothus cordulatus stems - in a thicket of same - well shaded by green leafage above.

9:30 a.m. - Just followed a Ruby-crowned Kinglet's "yerruping," and found a pair upon the summit of a fir assaulting vigorously a Blue-fronted Jay. Nearby, a (female) Western Tanager was flying about and at another jay in the top of a fir. One of the Blue-fronted Jays seen plainly was a full-grown young-of-the-year.

10: a.m. - Mrs. G. just found a Yellow Warbler's nest, 8 feet up, saddled on crossing stems in midst of willow thicket on meadow - perfectly typical site and construction for the species. Contents, 2 fresh eggs.

10:45 a.m. - Across the highway from camp, on a portion of Battle Creek Meadows that has had no cattle on it yet this year; grass and flowers a foot high; blue camas abundant in places; here and there clumps of willow; and many lodgepole pines, singly now and then, or in tracts. Birds I hear are: Western Meadowlark, two in full song; Robin, 2 or more in song; Lazuli Bunting, 2 singing; Warbling Vireo (one singing); Audubon Warbler (a (female) close by in a l-p pine); Calif. Purple Finch (one singing); Junco (one singing); Traill Flycatcher (pair close to me, and Mrs. G has seen one carrying a billfull of something into the midst of a willow thicket and in investigating); Lincoln Sparrow (a singing male centers within 3 acres about us).

Mr. Hoffmann shot an adult male, with a bob-tailed young one, of Golden-crowned Kinglet, in a dense group of small fir here on the Forest Service camp ground this afternoon. I saw a Red-shafted Flicker in flight over the tree-tops - not a common species here - in fact, far less seen than the Pileated Woodpecker.

June 23 10:00 a.m. - we have come 2 1/2 miles airline west of camp along side of Battle Creek Meadows, following the old road (see U.S.G.S quadrangle) to a little beyond the old bridge across Battle Creek. Big forest trees, yellow pines, fir, cedars, and sometimes sugar pines, extend down to the edge of the "meadows"; the latter consist of open pasture and also tracts of willows and lodgepole pines. The present highway pretty much parallels the old road to this point but thence goes down the canyon on the north side, to cross it several hundred feet, altitude, lower. At this end of the Meadows, the mountains pinch together, and the creek bottom ^^soon becomes a narrow canyon. Here are aspens, and a few alders. The Meadows are the property of one W. L. Gerber (?), and are fenced; everywhere astride the fences the vegetation is grazed down by the cattle and sheep which go thru [sic] the country or are seen at large over the forest lands; but inside the fences, the vegetation looks fine - not overgrazed - some of the enclosures not yet grazed at all, possibly reserved for hay. Took a 1 1/2 hour census of birds notes from the road near camp to here, as follows:
