All these things flashed through Donald's mind in a moment, while his hands were feeling out the exact condition of the mine. How long was that fuse? He traced it backward as its evil length stretched along the bottom of the tunnel. It led to the angle, and there he again encountered the fragments of burned wood. At one side the tunnel widened, and here its wall was entirely composed of this material. Where could it have come from? It was freshly charred. The Indians would never have brought it there and piled it in that confusion. It must have fallen from above! There must be an opening! If there only was, he would know just what to do. There would be no difficulty then about forming a plan.
With eager haste Donald began pulling away the burned ends of timbers and logs. He had hardly begun before the whole mass gave way, and slid down on him. Fortunately, there was not much of it, and, though he was nearly smothered by dust and ashes, he quickly scrambled from the débris, and listened with loudly beating heart. He realized that he had found an opening to the surface, and was wildly exultant over the discovery, but could hardly believe that the noise of the sliding material, which had sounded to him like an avalanche, should not have aroused the savages. So, for some minutes, he listened, and then, reassured by the continued silence, ventured to climb up to the open air. He had but a few feet to go, and once at the surface instantly recognized his surroundings. He was beside the ruins of Christie's quarters, and just beyond rose the black mass of the blockhouse, in which he had recently suffered so much.
But that glow in the east, against which it was outlined so distinctly! It could not be that the night was already gone and daylight near at hand. Yes, it was, though; and, realizing that his working time was now limited to minutes, Donald slid back into the tunnel, and began to carry the powder kegs, one at a time, toward its outer end, placing them as near the entrance as he dared venture. He was forced to work slowly in that confined space, as well as with the utmost caution; for, by the rapidly increasing light, he caught occasional glimpses of dusky forms passing and repassing the entrance, showing that the enemy was already astir. He expected each time that he returned from the further end of the mine to be confronted by some burly savage, and became so nervous at the prospect that the utmost exercise of his will power was required to enable him to complete his task. At length it was finished. All the kegs were removed to their new position and piled about the one whose open head admitted the fuse. The other end of this reached half way to the new place of exit.
Almost breathless with nervous excitement, he knelt beside the farther end of the fuse, and with trembling hands attempted to ignite it by a spark struck from flint and steel. Again and again the spark flew aside, but at length there came a slight flash and a spluttering flame.
Heavens! How fast that roughly made fuse burned! Almost like an open train of powder. Donald had hardly thought of his own danger; but a single glance at that hissing line of fire caused him to spring to his place of exit. He scrambled through it, and darted at full speed across the open toward the forest, heedless of everything save a desire to place as great a distance as possible between himself and the awful fire fiend about to leap forth.
As he reached the edge of the woods and turned to look, the explosion came. He saw a sheet of vivid flame, that dimmed the brightness of the rising sun, leaping in air. At the same instant, as though it had been a thunderbolt and hurled at him, he was struck senseless by a crashing blow on the head, delivered from behind.
The four or five crouching figures that had been grimly watching Donald's approach, and sprang up to receive him as he turned to look back, were for a moment petrified with fright at the suddenness and violence of the shock. Then, moved by a common impulse, and without a word being spoken, they lifted their unconscious captive, ran with him to the lake shore, bundled him into a canoe, and pushed off.
Upon the Indians behind the breastwork, where the full force of the explosion was felt, the effect was so disastrous that the panic-stricken survivors rushed madly for their canoes. Many of these were damaged, and some crushed beyond repair, by the rain of logs, stones, and other missiles hurled from the dense smoke-cloud that was slowly drifting to leeward in fleecy folds.
Although the blockhouse was violently shaken, it remained standing, and, after a moment of consternation, its garrison rushed out to hasten the flight of their terrified foes. A few ran to the breastwork on the lake shore, and gazed wonderingly at the smoking hole from which the torrent of flame had burst. The rest, headed by Christie, charged upon the Indians behind the creek hank, who, although preparing for flight, were not quite so bereft of their senses as those who had felt the full shock of the upheaval. Some of them even turned on the whites, who rushed so recklessly among them; so that for a minute a fierce hand-to-hand fight raged on the narrow strand, and even among the crowded canoes in the water. In the confusion of this mêlée Christie became separated from his men, and ere he realized the full peril of his position received several knife wounds in quick succession. Staggering under these, he fell, was instantly dragged into a canoe, and borne away.
It was only after the last of the canoes had made good its escape, leaving many dead savages behind, that the little force of breathless but exulting soldiers discovered their leader to be missing. In vain did they search for him. In vain did they run along the shore, firing ineffectual shots at the departing fleet. He was not to be found, nor had they any knowledge of his fate.
