The soldier nearest him replied that he feared he had not the requisite strength.

"Very well," said Donald; "pretend exhaustion and change places with me."

As this order was obeyed and the young ensign stepped forward, as though to take his comrade's place, he suddenly seized hold of an unsuspecting Indian, lifted him bodily, and flung him into the river. At the same moment the savage clutched his assailant's clothing, and as he cleared the boat dragged Donald after him over its side. The two remaining Indians, seized with a panic, leaped overboard and struck out for shore, while the three soldiers, bending to their oars, directed their craft with desperate energy toward the schooner, followed by a storm of bullets and a dozen canoes.

In the meantime, Donald and his antagonist, swept away by the current, were engaged in a frightful struggle for life and death, now rising gasping to the surface, then sinking to unknown depths, but always grappling, and clutching at each other's throat.

At length, when it seemed to the white lad that he had spent an eternity in the cruel green depths, when his ears were bursting and his eyes starting from their sockets, he found himself once more at the surface, breathing in great gulps of the blessed air, and alone. For a moment he could not believe it, but gazed wildly about him, expecting each instant to feel the awful clutch that should again drag him under. He was nearly exhausted, and so weak that had not a floating oar come within his reach he must quickly have sunk, to rise no more.

Clinging feebly to that Heaven-sent bit of wood, he kept his face above the water while his spent strength was gradually restored.

At the boom of a cannon, he lifted his head a little higher, and looked back. A cloud of blue smoke was drifting away from the now distant schooner, a boat was alongside, and a fleet of canoes was scurrying out of range. His recent companions had then escaped, and pursuit of them had so attracted the attention of the Indians that none had given him a thought. They doubtless never questioned but what that death grapple in the water had resulted fatally to both contestants. So much the better for him. No search would be made, and he might escape, after all. And dear Edith! At length he was free to go in search of her. With this thought the lad took a new hold on life, grasped his friendly oar more firmly, and tried to plan some course of action.

Making no motion that might attract hostile attention, he drifted passively, until the sun had set in a flood of glory, and the stars peeped timidly down at him from their limitless heights. By this time he was some miles below the fort, and near the eastern bank of the river. Though he had seen many canoes pass up stream, at a distance so great that he was not noticed, there was now neither sign nor sound of human presence, and very gently the young soldier began to swim toward land. How blessed it was to touch bottom again, then to drag himself cautiously and wearily into a clump of tall sedges, and lie once more on the substantial bosom of mother earth. For an hour or more he slept, and then, greatly refreshed, he awoke to renewed activity.
