“I think I’ll try wings next time!”

But our difficulties had only begun. As we had foreseen, it was a case of Alp above Alp, to the very limit of human strength and patience. However, it would have been impossible to go back. In order to descend the two precipices we had surmounted it would have been necessary to leave our life-lines clinging to the rocks, and we had not rope enough to do that. If we could not reach the top we were lost.

Having refreshed ourselves with a bite to eat and a little stimulant, we resumed the climb. After several hours of the most exhausting work I have ever performed we pulled our weary limbs upon the narrow ridge, but a few square yards in area, which constitutes the apex of the Grand Teton. A little below, on the opposite side of a steep-walled gap which divides the top of the mountain into two parts, we saw the singular enclosure of stones which the early white explorers found there, and which they ascribed to the Indians, although nobody has ever known who built it or what purpose it served.

The view was, of course, superb, but while I was admiring it in all its wonderful extent and variety, Hall, who had immediately pulled out his binocular, was busy inspecting the Syx works, the top of whose great tufted smoke column was thousands of feet beneath our level. Jackson’s Lake, Jenny’s Lake, Leigh’s Lake, and several lakelets glittered in the sunlight amid the pale grays and greens of Jackson’s Hole, while many a bending reach of the Snake River shone amid the wastes of sage-brush and rock.

“There!” suddenly exclaimed Hall, “I thought I should find it.”

“What?”

“Take a look through my glass at the roof of Syx’s mill. Look just in the centre.”

“Why, it’s open in the middle!” I cried as soon as I had put the glass to my eyes. “There’s a big circular hole in the centre of the roof.”

“Look inside! Look inside!” repeated Hall, impatiently.

“I see nothing there except something bright.”
