He grabbed frantically, hoping that his hands might come in contact with some projection to which he could cling, but the slippery sides of the hull slid past him at what seemed almost express train speed.

He was almost on the point of diving again to get away from the dangerous spot, when suddenly, his fingers closed over something. It was a rope, one of the hawsers that had not been fully hauled in when the boat left the last landing place some miles up the river.

With a glad cry, both the lad's hands closed over the precious rope. His joy was short lived. He found himself dropping back, the river craft still gliding past him.

The rope was paying out over the boat's side in his hands.

Phil Forrest was never more cool in his life, but he now began to realize the well-nigh hopeless position in which be found himself placed.

Suddenly the rope ceased paying out with an abruptness that jerked him clear out of the water. He fell back with a splash, all but losing hold of the rope as he did so.

"I've got it! I've got it!" exulted the lad. A rush of water filled his mouth, almost suffocating him.

"I guess I had better keep my mouth closed," thought the boy.

He was directly astern of the steamboat by this time, and this placed him in a much more favorable position than he had been while dragging along at the side.

Phil began resolutely to work himself along the rope hand over hand. It was a desperate undertaking, one calling for strength and courage of an unusual kind, but he never hesitated. His breath came in long, steady, sighs, for he was going though the water at such a rate of speed that breathing was made doubly difficult.
