The redskin had evidently been shot in the first volley from the flat, and had been clinging to the canoe ever since, too badly hurt to cry out or to swim to shore. But the sight of a hated foe revived his strength, and on the very second that he made his presence known he sprang at Nathan and clutched his throat.

Down went both, entangled with the rope, and tearing it loose from the anchorage in their struggles. The lad kept one hand free, and while he held his breath he stabbed repeatedly with the knife. After a few terrible seconds the grip on his neck relaxed, and he shot to the surface.

The Indian did not reappear, and Nathan lost no time in striking for the canoe. He swung it around by the dangling rope, and started to swim with it down-stream. Bang! went a musket from the promontory, and a bullet whistled overhead. A second shot followed after an interval of half a minute, but now lad and canoe were on the verge of the open passage through the falls. They went plunging down the slope of spray and waves, and three minutes later Nathan skillfully landed his prize on the outer side of the cluster of rocks.

Nathan's safe return was a joyful disappointment, for his friends had given him up when they heard the firing. In a few words the lad told the story of his adventurous swim, and some of the tributes to his bravery made him blush.

"Now let's be off while we've got the chance," cried Barnabas. "I judge, from the shootin', a part of the varmints are still lurkin' above the falls."

So the canoe was turned right-side up and the fugitives hurriedly embarked. They were a little crowded, but that discomfort they did not mind.

Either the enemy's weapons were empty, or else they could not see what was taking place for the darkness of the night. At all events, no shots were fired from the bank, and presently a swifter current took the canoe past the distant lights of Northumberland and out into the broad channel of the main river. The two muskets were reversed and used for paddles, and an hour before midnight the fort at Shamokin was safely reached.

Here the weary fugitives were warmly welcomed, and provided with supper and lodging. Barnabas extracted the packet of papers from his boot, and after drying them over a fire he restored them to their hiding-place. Much to Nathan's disappointment, no news had lately been received from the army; but the tidings of the Wyoming massacre had traveled quickly, and great alarm was felt lest the enemy should advance down the Susquehanna to raid the extensive military stores at Carlisle.

Cato was unfit for travel, and Proud and Cutbush, with the latter's family, decided to remain at Shamokin fort for a few days. McNicol also wished to stay, so that he might visit a married sister who lived at the settlement of Northumberland.

So, at dawn the next morning, Barnabas and the two lads said good-bye to their friends, and resumed their journey down the river in the canoe, satisfied that Simon Glass would give them no further trouble. Indeed, they were by no means sure that the ruffian had escaped drowning.
