After midnight her slumbers were disturbed by the unusual creaking of the boat, and the hasty puffs of steam from the escape-pipes. She awoke, and was at once sensible of the immense pressure to which the boilers were subjected. Awhile she lay and listened to the ominous sounds which indicated the danger of the boat; then, much alarmed, she rose and dressed herself. For nearly an hour she sat in the darkness of the room, during which time the danger seemed momentarily to increase, until, no longer able to endure such agonizing suspense, she was about to leave the room. At this moment Vernon was about to enter, when the explosion took place. The forward part of the Chalmetta was completely torn in pieces. The gentlemen's cabin was lifted from its supports, and torn into fragments. The unfortunate occupants of berths in this part of the boat were either instantly killed or severely wounded. The ladies' cabin, being at a greater distance from the immediate scene of the explosion, had not suffered so severely. Although torn from its position, and shattered by the shock, it had proved fatal to but a few of its occupants, who had been crushed by falling timbers. The hull of the boat was not injured by the explosion, but before those who had escaped a sudden death could recover their disordered faculties, the flames began to ascend from the wreck of the cabin, which had been precipitated upon the furnaces. The scene surpassed description. The groans of the wounded and scalded, the shrieks of those who were on the boat, expecting every moment to be carried down in her, mingled in wild confusion on the midnight air. Fortunately the passengers were mostly soldiers, accustomed to scenes of horror, who immediately turned their attention to the extinguishing of the flames. The Flatfoot, No. 3, approached within a short distance of the wreck, and a line was passed from her to the bow of the Chalmetta. Her passengers and crew were humanely assisting in rescuing those who had jumped or been thrown overboard in the disaster. By the aid of a fire-engine on board of the Flatfoot, which had approached near enough to render it available, the flames were extinguished. It was ascertained that the Chalmetta had received no serious damage in her hull; and as all the survivors had been picked up, the Flatfoot took her in tow, and proceeded up the river. Emily had been stunned by the explosion, and ere she could recover, Vernon, with a strong arm, bore her to the main deck. The boat was lowered into the water, and, before the passengers, or the petrified watch in the hold, could regain their self-possession, it was impelled by the strong arm of Vernon, and the ruffian who had been hired for the purpose, far astern of the wreck. The main deck was enveloped in clouds of steam, so that, when Vernon had handed Emily down, the movement could not be seen by Hatchie and his friends in the hold. In another instant the wreck of the cabins came tumbling down.
