"I think so. We are not in the channel as it is."

"I'm going to get a gun," came from Tom, and off he rushed to secure the firearm.

The raft had now swept so close that several on board could be seen plainly. They were a rough-looking sort, and the man with the long nose was the shrewdest of the lot.

"We'll have to turn in, or we'll be hit!" ejaculated Sam. "Those side logs are bound to strike the cabin!"

He pointed to some timbers that projected over the edge of the raft. They were only a few feet off and might crash into the cabin of the houseboat at any moment.

In anger at being forced to change his course, Captain Starr turned the houseboat toward the bank of the river. Then the big raft began to pass them, just as Tom reappeared, shotgun in hand.

"I ought to have you arrested for this!" stormed Captain Starr. His words were always louder than his actions.

"Bah!" answered the man with the long nose, in derision.

"Maybe you'd like to have a taste of this?" put in Tom, holding up the gun.

"Don't you dare to shoot!" yelled the man, and lost no time in sliding from his seat and out of sight.
