It was a wild-looking figure that raced along the trail toward Mummy Cañon that night. Half a mile from the school a small animal shot out from a clump of junipers and darted across his path just behind him. Believing it to be a wildcat, he doubled his speed, too much frightened to think of stopping, although his hat was whiffed off by the wind.

His hair was rather long and it was blown in disorder. Like a scary horse he shied at every large rock, dark hollow, or ghost-like stunted spruce or fir.

Up hill and down he ran, through ravine and along the precipice of a hollow known as “Baby Gorge.” Colorado nights are cool, even in the summer, and he did not become overheated. A few times he was forced to stop and walk for want of breath, but as soon as he recovered, on he went at the best speed he could make. He was a sturdy youngster and stood the test.

At last he reached Flathead Pass and hastened through, over a ledge of rock along the bank of the river. Another quarter of a mile, and he was able to see the lights of the lanterns of the hunters for the lost boy. On he ran, and as he neared the party ahead, he realized tremblingly that they were near the fatal waterfall. Now he began to wonder what he should do. He had had no plan in mind when he started out; all he could say to himself was that he must be present and watch the search. He did not intend to reveal himself, but wanted to be near when the body of Hal was taken out of the water.

Frank approached as near to the men by the waterfall as he thought safe. He stopped behind a clump of bushes and peered around to watch proceedings. Presently the doctor and his companions moved away from the cataract and stopped within a few feet of the bushes, and there the boy heard their excited discussion regarding the cries that seemed to issue from the falling water. Then he saw them cut a club for each and advance again toward the place of mystery.

The watching boy was intensely thrilled by what he had heard.

The suggestion that possibly the screams were those of a panther or a lynx added a new element of fear to the situation. But as he heard the strange sound repeated again and again, he dismissed all thought of a wild animal.

“It’s Hal’s ghost, I know; it can’t be anything else,” he chattered; and without knowing why, he left his place of concealment and started toward the waterfall. A dozen paces from the men he stopped, fearful of announcing his presence, yet half hoping he would be discovered. Just then Dr. Byrd turned and saw him.

CHAPTER IX
HAL A PRISONER

“Oh, he’s dead! Hal’s dead, and that’s his ghost screaming!” moaned Frank Bowler as he writhed in mental agony at the feet of Dr. Byrd.
