knife blade, and hold the elbow and fore-arm firmly to prevent any involuntary drawing back of the arm by Lieutenant Doane, at the critical moment.  When Doane was told that we were ready, he asked, “Where is the chloroform?” I replied that I had never administered it, and that after thinking the matter over I was afraid to assume the responsibility of giving it.  He swallowed his disappointment, and turned his thumb over on the cartridge box, with the nail down.  Hedges and Bean were on hand to steady the arm, and before one could say “Jack Robinson,” I had inserted the point of my penknife, thrusting it down to the bone, and had ripped it out to the end of the thumb.  Doane gave one shriek as the released corruption flew out in all directions upon surgeon and assistants, and then with a broad smile on his face he exclaimed, “That was elegant!” We then applied a poultice of bread and water, which we renewed a half hour later, and Doane at about eight o’clock last night dropped off into a seemingly peaceful sleep, which has been continuous up to the time of this writing, two o’clock p.m.[K]

Evening of September 4.—­I have been glad to have this rest to-day, for with the time spent in writing up a detailed diary in addition to the work about camp, I have been putting in about sixteen hours work each day.  So this afternoon a nap of two or three hours was a pleasant rest.  I strolled for a long distance down the shore, the sand of which abounds in small crystals, which some of our party think may possess some value.  Craters emitting steam through the water are frequently seen beneath the surface, at a distance of from forty to fifty feet from its margin, the water in which is very hot, while that of the lake surrounding them I found to be too cool for a pleasant bath.  In some places the lake water is strongly impregnated with sulphur.  One crater emits a jet of steam with a hissing noise as loud as that usually heard at the blowing off of the safety valve of a steam-boat.  In the clear light of the setting sun, we can see the three Tetons in a southwesterly direction.

Some member of our party has asked what is the meaning of the word “Teton” given to these mountains.[L] Lieutenant Doane says it is a French word signifying “Woman’s Breast,” and that it was given to these mountains by the early French explorers, because of their peculiar shape.  I think that the man who gave them this name must have seen them from a great distance; for as we approach them, the graceful curvilinear lines which obtained for them this delicate appellation appear angular and ragged.  From our present point of view the name seems a misnomer.  If there were twelve of them instead of three, they might better be called the “Titans,” to illustrate their relation to the surrounding country.  He indeed must have been of a most susceptible nature, and, I would fain believe, long a dweller amid these solitudes, who could trace in these cold and barren peaks any resemblance to the gentle bosom of woman.
