In proceeding down the great river the boys had kept on only sufficient power to gain steerway, as they were in no haste to reach the Gulf of Mexico, which was their final destination on that trip. They decided that day to travel nights no more.

After supper had been eaten the boys switched on all the lights and sat out on deck. There was a brilliant moon, but they preferred to let everybody in that vicinity know that they were there—hence the electric lights.

“If any one sneaks up on us now,” Alex. laughed, “he’ll have to get to us by the under-water route! And, even then, one of us would be apt to see him. Captain Joe is losing his record as a watch dog, but I guess Teddy can take his place.”

Captain Joe, as if he understood every word that had been said, and resented the insinuation, walked up to the prow and sat in a meditative mood, looking over the small “tow-head” which sheltered the boat from the current. He sat there motionless so long that Alex. finally called attention to him.

“Ah knows what he’s done seein’!” exclaimed Mose. “Dar’s a big fat coon watchin’ us from dat mess ob bushes. Ah done seen him long time ago!”

An inspection of the spot pointed out showed half a dozen evil-looking negroes watching the boat.

[CHAPTER XI—FIRE-FACES ON THE ISLAND]

“What are they squatting there watching the boat for?” queried Jule, as the prow light fell full on the group of negroes on the island. “They don’t look good to me!”

“If we keep away from them,” Case suggested, “and don’t try to stare them out of countenance, they’ll probably keep away from us. They do look fierce, though!”

While the boys discussed the matter the negroes moved away from the shore of the island, where they were under the boat lights, and secreted themselves behind a patch of willows which fringed the “tow-head,” for the place where they were was little else.
