“What’s the matter?” asked Ned, sitting up suddenly. He was easily awakened, and the sound of Bob’s voice, with the movement of Jerry served to arouse him. “What’s the matter?” he repeated. “Are they after us? Is Noddy up to his old tricks?”

“I don’t know what’s the matter,” replied Jerry in a low voice. “I was awakened by feeling the boat rock, and I got up to see what the trouble was. I haven’t found out yet.”

“Maybe we’re adrift,” suggested Ned. “We may have swung down stream and hit the bank.”

Jerry reached for a swinging lantern, and, parting the canvas side awnings, held the light over the rail. By the gleam the boys could see that they were still tied to the shore trees by bow and stern lines.

“The boat hasn’t drifted,” said Jerry. “Something moved it. I heard a noise in the water as if there was a big fish, but who ever heard of whales or sharks in the river, and it must have been something as big as that to cause us to careen so.”

“Maybe it was a log that hit us,” suggested Ned.

“I think not; I would know the bump of a log,” said Jerry. “Hark! What’s that?”

Both boys listened intently. Off toward the farther bank could be heard a faint splashing, as if a large body was moving in the water.

“Light the search lantern, and we’ll throw a beam over in that direction,” said Ned. Jerry crept forward and soon had the big illuminator kindled. Then he suddenly turned the beams full on in the direction of the splashing sound.

For a moment nothing could be distinguished save the green bank that bordered the river. Then, as Jerry swung the search light in a half circle he “picked up” a dark figure that was crawling up the sloping shore.
