They did not appear to notice the raft at all, and soon they were lost to sight as our friends drifted around a bend.
Prof. Drearland drew a long breath of relief. He evidently was very much afraid of the elephants.
When the raft had drifted perhaps five miles down the river the sight of cultivated fields met the eyes of our friends.
While they were speculating as to what would be the next thing to turn up they were startled to hear the reports of firearms down the river.
"That is Doc Clancy, I'll wager!" exclaimed Van. "Some of the natives have attacked the raft."
"You are right," returned Jack. "Now we must look out for squalls."
The further they drifted the narrower the stream became, while the current kept on increasing in force.
The mass of timber was now floating along at the rate of at least ten miles an hour.
Presently the explorers came in sight of a large village of log houses, situated near the river bank.
Hundreds of white people could be seen about the vicinity, and our friends at once concluded that this was the nation to whom the Amazons belonged.
