The seconds passed, and all the while the current of the river was bringing that object closer to them. Max found himself wishing it would hasten, for truth to tell he did not much like the way the bridge was trembling now. Instead of occasional vibrations it seemed to be a steady pull, as though the force of the flood had reached a point where it could not be much longer held back.
Some of those ashore were shouting to them again, as though their fears had broken out once more, and they wished the boys would not persist in taking such great chances, even though in a good cause.
A minute had gone.
"Looks like a raft to me," announced Bandy-legs, presently, and the others were inclined to agree with him that far.
"But is there any one aboard?" asked Max.
"I c'n see something there, but just what it might be I wouldn't like to say," the boy with the eagle eye announced.
Still they lingered, although those heavings were gradually growing a trifle more pronounced all the while. They must have shattered what little nerve Shack Beggs had remaining, for although he had not gone more than half way between the four chums and the further shore, he had turned around, and was now approaching them again. His face looked strangely ghastly, owing to his deadly fear; and the way in which Shack tried to force a grin upon it only made matters worse.
He had the appearance of one who was solemnly promising himself that if only he might be allowed to reach a haven of safety again he would never more be guilty of attempting such a silly act on account of a dare.
In fact, Shack was watching the chums eagerly every second of the time now. He depended on them to serve as his barometer. Should they make a sudden move toward the Carson side of the river he was in readiness to fairly fly along, in the hope of catching up with them.
Max turned his attention once more up the stream, and toward that approaching floating object. He wondered whether he was going to be called upon to once more make use of that friendly rope in rescuing some flood sufferer from peril.
