Mr. Folsom, in speaking of the various efforts made to organize an expedition for exploration of the Yellowstone says: 

In 1867, an exploring expedition from Virginia City, Montana Territory, was talked of, but for some unknown reason, probably for the want of a sufficient number to engage in it, it was abandoned.  The next year another was planned, which ended like the first—­in talk.  Early in the summer of 1869 the newspapers throughout the Territory announced that a party of citizens from Helena, Virginia City and Bozeman, accompanied by some of the officers stationed at Fort Ellis, with an escort of soldiers, would leave Bozeman about the fifth of September for the Yellowstone country, with the intention of making a thorough examination of all the wonders with which the region was said to abound.  The party was expected to be limited in numbers and to be composed of some of the most prominent men in the Territory, and the writer felt extremely flattered when his earnest request to have his name added to the list was granted.  He joined with two personal friends in getting an outfit, and then waited patiently for the other members of the party to perfect their arrangements.  About a month before the day fixed for starting, some of the members began to discover that pressing business engagements would prevent their going.  Then came news from Fort Ellis that, owing to some changes made in the disposition of troops stationed in the Territory, the military portion of the party would be unable to join the expedition; and our party, which had now dwindled down to ten or twelve persons, thinking it would be unsafe for so small a number to venture where there was a strong probability of meeting with hostile Indians, also abandoned the undertaking.  But the writer and his two friends before mentioned, believing that the dangers to be encountered had been magnified, and trusting by vigilance and good luck to avoid them, resolved to attempt the journey at all hazards.

We provided ourselves with five horses—­three of them for the saddle, and the other two for carrying our cooking utensils, ammunition, fishing tackle, blankets and buffalo robes, a pick, and a pan, a shovel, an axe, and provisions necessary for a six weeks’ trip.  We were all well armed with repeating rifles, Colt’s six-shooters and sheath-knives, and had besides a double barreled shotgun for small game.  We also had a good field glass, a pocket compass and a thermometer.

Mr. Folsom followed the Yellowstone to the lake and crossed over to the Firehole, which he followed up as far as the Excelsior geyser (not then named), but did not visit the Upper Geyser basin.  On his return to Helena he related to a few of his intimate friends many of the incidents of his journey, and Mr. Samuel T. Hauser and I invited him to meet a number of the citizens of Helena at the directors’ room of the First National Bank in Helena; but on assembling
