Gary himself had once known something about minerals, his dad having sent him to take a course in mineralogy at Denver with a view to making of his son a respectable mining engineer. Gary had spent two years in the school and almost two years doing field work for practice, and had shown a certain aptitude for the profession. But Mills, the motion-picture director, had taken a company into Arizona where Gary was making a report on the minerals of a certain district, and Gary had been weaned away from mines. Now, he was so saturated in studio ideals and atmosphere that he had almost forgotten he had ever owned another ambition than to become a star with a company of his own.

Well, this man then—the man about whom he found himself thinking so intently—must have found something here in the cañon. He did not know why he believed it, but he began to think that Waddell had found gold; though it was not, properly speaking, a gold country. But Gary remembered to have noticed a few pieces of porphyry float on the bluff the morning that he had spent in looking for the man who shouted in the night. The float might easily be gold-bearing. Gary had not examined it, since he had been absorbed in another matter. It is only the novice who becomes excited and builds air castles over a piece of float.

Gary turned his head abruptly and looked back, exactly as he would have done had a man approached and stood at his shoulder. He was conscious of a slight feeling of surprise that the man of whom he was thinking did not stand there beside him.

“I’ll be getting ’em too, if I don’t look out,” he snorted, and dumped the mottled cat unceremoniously on the floor.

It has been said by many that thoughts are things. Certainly Gary’s thoughts that evening seemed live things. While he was washing the dishes and sweeping the cabin floor, he more than once glanced up, expecting to see the man who looked like a miner. The picture he had conjured seemed a living personality, unseen, unheard, but nevertheless present there in the cabin.

Gary was an essentially practical young man, not much given to fanciful imaginings. He did not believe in anything to which one may permissibly attach the word psychic. Imagination of a sort he had possessed since he was a youngster, and stories he could weave with more or less originality. He did not, therefore, run amuck in a maze of futile conjecturing. He believed in hunches, and there his belief stopped short, satisfied to omit explanations.

That night fell pitch black, with inky clouds pushing out over the rim rock and a wind from the west that bellowed across the cañon and whipped the branches of the pines near the cabin. Above the clouds played the lightning, the glare of it seeping through between the folds and darting across small open spaces.

Gary sat in the doorway watching the clouds with the lightning darting through. True to his type and later training, he was thinking what a wonderful storm scene it would make in a picture. And then, without warning, he heard a voice shouting a loud halloo from the bluff. Again it called, and ended with a wail of pain.

Gary started. He turned his face to the cañon side and listened, deep lines between his eyebrows. It was almost a week since he had heard the call, and it did not seem natural that the man should be shouting again from the same point on the bluff. He had been so sure that the fellow, whoever he was, had left the cañon that first night. It was absolutely illogical that he should return without coming near the cabin.

Gary got up and stood irresolute in the doorway. The voice was insistent, calling again and again a summons difficult to resist.
