by the floating masses of ice from the north. This, however, is a matter of little consequence. We are now on the summit of the great, the transcendent Sneffels, and here are its two peaks, north and south. Hans will tell you the name by which the people of Iceland call that on which we stand.
My uncle turned to the imperturbable guide, who nodded, and spoke as usual—one word. "Scartaris."
My uncle looked at me with a proud and triumphant glance. "A crater," he said, "you hear?"
I did hear, but I was totally unable to make reply.
The crater of Mount Sneffels represented an inverted cone, the gaping orifice apparently half a mile across; the depth indefinite feet. Conceive what this hole must have been like when full of flame and thunder and lightning. The bottom of the funnel-shaped hollow was about five hundred feet in circumference, by which it will be seen that the slope from the summit to the bottom was very gradual, and we were therefore clearly able to get there without much fatigue or difficulty. Involuntarily, I compared this crater to an enormous loaded cannon; and the comparison completely terrified me.
"To descend into the interior of a cannon," I thought to myself, "when perhaps it is loaded, and will go off at the least shock, is the act of a madman."
But there was no longer any opportunity for me to hesitate. Hans, with a perfectly calm and indifferent air, took his usual post at the head of the adventurous little band. I followed without uttering a syllable. I felt like the lamb led to the slaughter.
In order to render the descent less difficult, Hans took his way down the interior of the cone in rather a zigzag fashion, making, as the sailors say, long tacks to the eastward, followed by equally long ones to the west. It was necessary to walk through the midst of eruptive rocks, some of which, shaken in their balance, went rolling down with thundering clamor to the bottom of the abyss. These continual falls awoke echoes of singular power and effect.
Many portions of the cone consisted of inferior glaciers. Hans, whenever he met with one of these obstacles advanced with a great show of precaution, sounding the soil with his long iron pole in order to discover fissures and layers of
