Something had happened there a few thousand centuries before, and in a moment of evident spleen and vexation the earth had vomited up that pile of rock debris, and Jolly Roger good humoredly told himself and Peter that it was an act of Providence especially intended for them, though planned and erupted some years before they were born.
The third afternoon of their hiding, Jolly Roger decided upon action.
This afternoon all of the caloric guns of an unclouded sun had seemed to concentrate themselves on the gigantic rock-pile.

Though it was now almost sunset, a swirling and dizzying incandescence still hovered about it.

The huge masses of stone were like baked things to the touch of hand and foot, and one breathed a smoldering air in between their gray and white walls.
Thus forbidding looked the Stew-Kettle, when viewed from the plain.

But from the top-most crag of the mass, which rose a hundred feet high at the end of the Ridge, one might find his reward for a blistering climb.
On all sides, a paradise of green and yellow and gold, stretched the vast wilderness, studded with shimmering lakes that gleamed here and there from out of their rich dark frames of spruce and cedar and balsam.
And half way between the edge of the plain and this highest pinnacle of rock, utterly hidden from the eyes of both man and beast, nestled the hiding place which Jolly Roger and Peter had found.
It was a cool and cavernous spot, in spite of the Sahara-like heat of the great pile.

In the very heart of it two gigantic masses of rock had put their shoulders together, like Gog and Magog, so that under their ten thousand tons of weight was a crypt-like tunnel as high as a man's head, into which the light and the glare of the sun never came.
Peter, now that he had grown accustomed to the deadness of it, liked this change from Indian Tom's cabin.
