But there was no sleep for Gerald Ainley. He sat there staring at the water rushing by, reflecting the crimson flare of the Northern night. And it was not crimson that he saw it, but ochre-coloured as he had seen it earlier in the day, hurrying towards the rapids below, and to that ninety-foot leap into the gorge. And all the time, in vision, he saw a canoe swept on the brown flood, a canoe in which crouched a chestnut-haired girl, her grey eyes wide with fear; her hands helplessly clasped, as she stared ahead, whilst the canoe danced and leaped in the quickening waters hurrying towards the ramparts below, which for aught she knew might well be the gates of death.

Sometimes the vision changed, and he saw the canoe in the rapids below the ramparts, and waited in agony for it to strike one of the ugly teeth of rock. Again and again it seemed that it must, but always the current swept it clear, and it moved on at an increasing pace, swept in that quick mill-race immediately above the falls. On the very edge he saw it pause for a brief fraction of time and then the water flung it and the white-faced girl into the depths beneath, and he saw them falling, falling through the clouds of spray, the girl's dying cry ringing through the thunder of the waters. He cried out in sudden agony.

"My God! No!"

Then at the sound of his own cry, the vision left him for a time, and he saw the river as it was, rosy in the light of the midnight sun. A sound behind him caused him to turn round. The Indian, awakened by his cry of anguish, had sat up and was staring at him in an odd way.

"It is all right, Joe," he said, and with a grunt the Indian lay down to sleep again.

Ainley could not remain where he was to become again the prey of terrible imaginations. Rising to his feet, he stumbled out of the camp, and began to walk restlessly along the bank of the river. He was body-tired, but his mind was active with an activity that was almost feverish. Try as he would he could not shut out the visions which haunted him, and as fast as he dismissed one, a new one was conjured up. Now, as already shown, it was the canoe with the girl dancing to destruction, now that final leap; then again it was that broken piece of flotsam by the drift-pile at the end of the gorge; and later, in some still reach far down the river, a dead girl, white-faced, but peaceful, like drowned Ophelia.

He walked far without knowing it, driven by the secret agonies within, and all the time conscious that he could not escape from them. Then that befell which put a term to these agonizing imaginings. As he walked he came suddenly on the ashes of a camp fire. For a moment he stared at it uncomprehendingly. Then his interest quickened, as the state of the ashes showed some one had camped at this place quite recently. He began to look about him carefully, walking down the shelving bank to the edge of the river. At that point there was a stratum of soft clay, which took and preserved the impression of everything of weight which rested upon it; and instantly he perceived a number of footmarks about a spot where a canoe had been beached twice.

Stooping he examined the footmarks minutely. There was quite a jumble of them, mostly made by a long and broad moccasined foot, which was certainly that of a man; but in the jumble he found the print of smaller feet, which must have been made by a youth or girl. A quick hope kindled in his heart as he began to trace these prints among the others. He had little of the craft of the wilds, but one thing quickly arrested his attention—the smaller footprints all pointed one way and that was down the bank towards the water. Now why should that be? Had the person who had made those footprints not been in the canoe when the owner had landed to pitch camp? And if such were the case, and the maker of them was indeed a woman, what was she doing here, alone in the wilderness?

Had Helen Yardely been saved by some fortunate chance, and wandering along the river bank, stumbled on the camp of some prospector or trapper making his way to the wild North? His mind clutched at this new hope, eagerly. Hurriedly he climbed the sticky bank and began feverishly to search for any sign that could help him. Then suddenly the hope became a certainty, for in the rough grass he saw something gleam, and stooping to recover it, found that it was a small enamelled Swastiki brooch similar to one which he had seen three days before at Miss Yardely's throat.

As he saw this he gave a shout of joy, and a moment later was hurrying back along the bank to his own encampment. As he went, almost at a run, his mind was busy with the discovery he had made. There were other brooches in the world like this, thousands of them no doubt, but there were few if any at all in this wild Northland, and not for a single moment did he question that this was the one that Miss Yardely had worn. And if he were right, then the girl was safe, and no doubt was already on her way back to her uncle's camp in the care of whatever man had found her.
