After a time the boys switched off the prow light, turned on the small lamp in the cabin, and sat down to consider seriously the events of the night. While they talked, the clouds drifted away, and the whole surface of the river was flooded with moonlight. The flame on the south bank was seen no more. It had evidently been built as a beacon for the men in the ship’s boat.

After a time, Captain Joe, who had been sitting in the middle of the deliberative circle in the cabin, raced out to the deck. The boys heard him growling, heard a conciliatory human voice, and then a quick fall.

When the boys switched on the prow light and gained the deck, they found Captain Joe standing guard over a slender youth who had evidently fallen to the deck to escape being tumbled down by the dog. They gathered about waiting for him to speak—waiting for some explanation of his sudden appearance on the motor boat. Captain Joe seemed proud of his capture, and remained with threatening teeth within an inch of the boy’s throat.

“Say, you!” shouted Alex. “Did you come by parcel post? We’ve been getting letters all right, but no such packages as this.”

“Looks to me like he must have come in a parachute,” Jule suggested. “Where’s your boat, kid?” he added.

The visitor smiled brightly and sprang alertly to his feet. He looked from face to face for a moment, smiling at each in turn, and then pointed to a light canoe bumping against the hull of the Rambler.

He was a lad of, perhaps, eighteen, slender, lithe, dark. His clothing was rough and not too clean. His manner was intended to be ingratiating, but was only insincere.

“What about you?” demanded Alex. “Do you think this is a passenger boat?”

“A long time ago,” replied the visitor, speaking excellent English, “I read of the Rambler and her boy crew in the Quebec newspapers. When I saw the boat here to-night, I ran away from my employer and came out to you. I want to go with you wherever you are going.”

“You’ve got your nerve!” Alex cried.
