It had now grown quite dark. We quickened our pace, for I was too prudent a traveler to care to expose myself to the night dew.

As we drew near the grove there appeared to be a low wall on one side of it.

“This way, Bulger,” said I, “this long line of boulders will protect us from the night winds, if any should rise. Let us creep under its edge and lay our tired limbs down on the soft grass.” He looked up with softened gaze and gave one or two consenting wags to his tail.

Nestling close under the edges of several of the largest of the boulders, at a point where they formed a sort of sheltered nook, we soon fell into a deep sleep, I sitting half upright and Bulger pillowing his head upon my lap.

Once or twice in the course of the night I awoke to find my brow beaded with perspiration. I put my hand on Bulger; he too was awake, and his tongue was lolling from his mouth. Both of us seemed to have been seized with a strange fever. The direst forebodings took possession of me. Had we landed upon a shore along which lurked some deadly miasm? Possibly we might not live to see the light of another day. It required all my self-control to banish such terrible thoughts from my mind. But so tired was I to the very bone that I soon fell asleep again, reassured as I was by the example set me by Bulger. It was, however, a fitful slumber, for the heat of our bodies had now become so great that the very ground upon which we were lying felt warm to my touch. At length, to my joy, I caught the first, faint glimpse of the dawn. I was now in a perfect glow from head to foot. And so was Bulger. Suddenly it burst upon my mind that possibly we might have lain down in a volcanic region; that, mayhap, fierce, subterranean fires were raging beneath our very heads. I rose to my knees with a bound, and placed both of my hands upon the nearest boulder. Fancy my horror upon feeling that its surface was not only hot, but that it yielded to the pressure of my hands, and gave forth groans, hissings and rumblings. In an instant I was on my feet. Bulger did not wait to be called. Determined to verify my suspicions,—for discretion was always a reasonable part of my valor, I hastened from one boulder to another within the circle where we had been lying, and pressed my hands upon them with all my strength. Deep, rumbling and hissing sounds came forth from the ground everywhere about me, and seemed to awaken responsive cries far and near, as if one giant tossing in his sleep disturbed the slumbers of his fellows.

“Bulger!” I cried, “we stand upon the ground of death; this is but the outer wall of a crater, it is aglow with subterranean heat; only the merest shell—so thin that it yields to my pressure—is between us and destruction. Fly, fly, faithful dog!”

The morning sun now burst forth with a flood of golden light.

As far as my eye could reach, extended this same boulder-like parapet, shutting out my gaze from the abyss through which the volcano was now about to spout its liquid fire; for all at once the boulders began to rock from side to side, giving forth such dreadful rumblings that I knew the eruption was to be preceded by an earthquake.

A sickening fear seized hold of me; my legs bent like pipe stems, beneath the weight of my body.

Bulger saw that his loved master was chained to the ground.
