There was no doubt as to the meaning of the column of flame that turned the darkness into day behind them. It was so near that they could hear its ominous roar, while the black forest walls on either side of the river were bathed in a crimson glow from its baleful light. A vast cloud of smoke, through which shot millions of sparks, trailed and eddied above it, while, with the hoarse voice of escaping steam, the blazing craft sounded its own death-note.
As the monster came tearing down the channel of crimson and gold that opened and ever widened before it, our raftmates were fascinated by the sight of its sublime but awful approach. They stood motionless and speechless until roused to a sudden activity by Billy Brackett's shout of "Man the sweeps, fellows! She is unmanageable, and headed for us as straight as an arrow. If we can't get out of the way she'll be on top of us inside of two minutes more!"
Like young tigers the boys tugged at the heavy sweeps; but they might as well have tried to extinguish the floating volcano that threatened them with destruction as to remove that mass of timber beyond reach of danger within the time allowed them. The task was an impossible one; and as they realized this fact, the crew of the Venture prepared to launch their skiff, abandon the raft, and row for their lives.

CHAPTER XXXV.
BIM'S HEROISM.
As the burning steamboat swept down towards the low-lying raft the destruction of the latter appeared so certain that its crew abandoned all hope of saving it; and, taking to their skiff, sought by its means to escape the threatened danger. It was a forlorn hope, and promised but little. Even with Billy Brackett's strong arms tugging at its oars, the heavily laden skiff seemed to move so slowly, that but for the ever-widening space between them and the raft they would have deemed it at a stand-still. They gazed in silence and with fascinated eyes at the on-coming terror. At length, with a sigh of thankfulness, they saw that they were beyond its track, and Billy Brackett's labors were somewhat relaxed.
