came to the distended gullet, I could see the "seeds" showing thru the transparent walls! But the sole contents proved to be smooth bright green caterpillars, 13 of them, very uniform in size, 12 to 17 mm. long, tho decidedly stretchable.

Up to summit of Broke-off Mt. and back, with family. Left camp at 7 a.m., in Ford, up "Lassen road" to where "short trail" to Broke-off turns off to left (not more than 1/2 miles below "Soupan springs." From there to the top by trail in about 4 miles, 7000 to 9500 ft. alt. two life-zones are traversed - Canadian, with red fir as chief indicated, and Hudsonian, with alpine hemlock as indicator. But there is much blending between these two, and no "line" can be drawn to separate them. The middle of the belt of mergence on the south-east side of Broke-off I should say averaged about 8000 ft. There is no true timberline on this mountain, altho [sic] the upper 400 non-precipitous feet of the top is mostly bare. Yet scrubby hemlocks go up in places to within a few yards of the brightest parts of the short crest.

Mr. John W. Gransbury is the present Forest Lookout on the top, which is provided with a very comfortable glass-sided lookout house - rather airy in "feeling", as it is on the brink of the crumbling ^^{east and} northeast declivity, from which rocks often fall. As I waved the top, at 12:30, two Duck Hawks passed close over me and directly over the house.
