"It's too late to outen the fire," cried Barnabas. "The explosion may come any moment! Jump for your lives!"
Just then the flat swung over the falls, quivered and tossed amid the rocks and waves, and darted on to the deep and sluggish water below. Barnabas and Cutbush sprang past the flames to the bow, the former taking Molly in his arms, and the latter grabbing his wife. They and Cato sprang into the river at the same time that McNicol and the two lads jumped from the stern, and as hard as they could the whole party swam out toward mid-channel, scarcely heeding the two shots that were fired at them from the cover of the bank. They safely gained a cluster of rocks with a fringe of gravel at the base, and from behind this shelter they turned to watch the blazing flat as it drifted by at a distance of twenty feet.
AS THEY LOOKED THE EXPLOSION CAME
They had hardly looked when a terrific explosion came, casting a red glare all around, and seeming to shake the very bottom of the river. A shower of sparks and splinters fell, and huge waves rolled in all directions. For a second or two the shattered craft bobbed up and down, still blazing here and there. Then it lurched under and disappeared, and darkness and silence settled on the scene.
The situation of the little party was now disheartening. They were stranded on a rocky bar well out in the channel, dripping wet, and without means of safely getting away. They were almost defenseless in case of an attack, and to attempt to swim to shore would be a desperate and foolhardy proceeding under the circumstances.
But, in the stupor that followed the explosion, the first impression of the castaways—one and all—was a feeling of intense gratitude for the perils they had escaped, and, before they could realize how badly off they still were, a faint shout came floating over the water, and a dark form was seen struggling toward the rocks from a ledge higher up stream and nearer the bank. The swimmer made a gallant fight against the current, and when he finally gained the bar all were surprised and overjoyed to recognize Morgan Proud.
"Given me up, had you?" the plucky fellow exclaimed, as he clasped hands with his friends. "Well, I had a close call. That redskin stuck to me till we went over the falls. Then we parted company, and after I reached yonder rock I didn't spy him again. I was lying over there getting my breath back when the flat took fire and blew up."
"Did you see anything of Simon Glass?" inquired Barnabas.
"He shot by, swimming like a fish," declared Proud, "and I lost sight of him among the ledges and shoals below my rock. I daresay he got safe to shore."
