“This beats the deuce!” he muttered, at last, withdrawing from the bushes and throwing a puzzled look about him into the dark. “What the mischief1 is going on? It can’t be that I imagined I heard a cry for help. If I didn’t, why can’t I find somebody or something to account for it?”
He was greatly disturbed by his failure to locate the source of that alarm. Finally he gave up, and started to regain2 the road that led down the slope and in among the mine buildings. Scarcely had he turned, however, when that cry in the night once more smote3 upon his ears.
He whirled to an about face in a flash. “Where are you?” he called.
The cry was repeated, apparently4 coming from a mass of shadow, to his left, and farther down the slope. He plunged5 on into the gloom.
“I’ll find out what’s back of this if it takes a leg,” he declared to himself.
The next moment he stumbled over some obstacle, and fell forward. He threw out his hands instinctively7 to ease his fall, but they came in contact with nothing more substantial than thin air.
118
He dropped through space—not far, yet far enough to give him quite a jolt8 when he landed on the hard rocks. After a moment he scrambled10 to a sitting posture11 and rubbed his bruised12 shins.
On every side of him the gloom was thick. He could look up, however, and see an oblong patch of sky, studded with stars.
“Thunder!” he exclaimed ruefully. “There’s an open cut on the slope, and I’ve stumbled into it. That’s what a fellow gets for tracking trouble over ground he doesn’t know anything about. But that cry for help! It certainly gets my goat.”
He had lost his cap in his fall, and he groped around in the dark until he found it. Then, getting to his feet, he made his way to the steep bank and began climbing.
An “open cut” is a gouge13 in the earth made for purposes of exploration. Usually an “open cut” is dug or blasted out in order to make sure of surface indications of a vein14, and sometimes it is made in the hunt for a vein that has been lost.
Yet it made little difference how or what that particular open cut was there. The fact of most importance to Merry was that he had fallen into it.
His bruises15 were of small consequences; and many a time he had landed from a pole vault16 with a harder jolt. When a youngster keeps in the pink of physical condition, a hard fall now and then is nothing to worry him.
Presently Frank managed to paw and scramble9 his way to the top of the steep bank; and there he perched, trying to figure out what in blazes it was that had lured17 him into the pitfall18. He could make nothing of it, and at last turned his attention to the buildings below him.
That was not his first visit to the Ophir mine, by any
119
means. He was fairly familiar with the location of the different buildings, and he knew that the cyanide plant lay at a considerable distance to the left of the mill. It surprised him, though, to discover that his wanderings across the slope had brought him to a point directly opposite the cyanide tanks.
Cyanide of potassium, it may be explained, is one of the two commercially valuable solvents19 of gold. This cyanide eats up the gold and holds it in solution. For that reason, the drug is used in treating refuse from a stamp mill. In such refuse—technically known as “tailings”—there is always present a small amount of yellow metal which the quicksilver on the copper20 plates of the mill fails to “catch.” If it were not for the cyanide, this gold would prove a total loss.
The tailings are thrown into tanks, arranged in rows like a series of giant steps. From a large reservoir, high above the rows of vats21, the cyanide solution flows by gravity into all the tanks below—entering at the bottom and percolating22 through the tailings upward to the top, where it flows off and into the row of tanks next below. The solution takes up the gold as it flows, finally depositing its burden of wealth on zinc23 shavings in what is called the “zinc box.” From the zinc box the solution drops down another step into a sump tank, and from there, at stated intervals24, it is pumped back into the reservoir.
Merriwell was familiar with the cyanide plant at the Ophir mine. He had been showed around by the super, and the work had been explained to him. Consequently he was able to recognize the plant from the open cut the moment his eyes rested on the black bulk of the tanks.
For the present the tanks were out of commission. A cyanide “clean-up” is a long and tedious operation,
120
and the work pauses for a longer or shorter period while the work is going on.
“I’ll slip down among the tanks and look for Lenning,” Frank murmured. “After I talk with him a while, I’ll return to the hotel and go to bed. If the bullion25 is locked up in a safe, I guess he won’t have any trouble taking care of it. Funny I didn’t think of that before. The strong box here must be a regular teaser for a cracksman.”
Carefully he gained his feet and descended26 the rough slope to the tanks. At his left, as he stood by the end of the upper tier of vats, was the laboratory building, where the cyanide expert kept his store of the deadly poison that stole the gold from the tailings, and where he had his assay27 equipment, his furnaces, crucibles28, et cetera. The building was dark, and Frank, sure that Lenning was not inside of it, but on duty around the tanks, paid the structure no attention.
Comparatively close to the mill, where the rumble29 of the stamps drowned every other noise, to call for Lenning was useless. Frank would have to plunge6 in among the tanks and look for him. Scrambling30 over the tailings piles that cluttered31 the ground, he began his search.
Lenning was not in the vicinity of the first row, and Frank dropped to the next tier. He wasn’t there, either. In spite of the gloomy shadows cast by the big vats, the lad was able to see with tolerable clearness. The third and last row remained to be investigated, but here the same ill luck rewarded Frank’s search. Lenning was not in evidence around the tanks.
Possibly, Frank thought, the new watchman might be in the mill. Or, if he was not there, some of the night shift might know where he could be found. Just as Frank was turning to start for the mill, he saw a flash
121
of light through one of the windows of the laboratory. He halted and stared, a trifle bewildered.
Not five minutes before he had looked at the laboratory, and the windows had all been dark. How did it happen that now there was a light in one of them?
“Not much of a mystery about that,” he finally decided32. “Some one has gone into the place and lighted a lamp. It may be Lenning; or, if not Lenning, then some one who has been helping33 with the clean-up. I’ll——”
The muttered words died on Frank’s lips. Under his eyes, as he continued to watch the window, the light winked34 out and again left the laboratory in darkness.
“I guess that’s easily explained, too,” he presently decided. “The fellow that lighted the lamp put it out again. It was Lenning, of course. As I went hunting for him among the tanks, he had to go to the laboratory for something. That’s how I happened to miss him. He has got what he wanted, and so he has put out the light and will soon be coming back. I’ll wait here for him.”
Frank kept his eyes fixed35 on the dark side of the laboratory building, where he knew the door was located. Every moment he expected Lenning to appear, walking toward him out of the shadow of the laboratory wall. But the seconds grew into minutes, and still Lenning did not come. The waiting lad was forced to the conclusion that there was something strange about all this.
“If there’s anything wrong,” he thought, “I ought to find the superintendent36, and report. But how do I know there is anything wrong? Maybe all I see is a part of the night’s work, and if I went to the super he’d only have the laugh on me. I’d better investigate a little before I spread any news of trouble.”
The roaring mill, with its glittering lights, suggested quick help in the case of emergency. Frank had a vague
122
notion that it would be well to go there and make some inquiries37 before investigating the laboratory. But, if he went to the mill, the fellow who had struck a light in the laboratory would have time to come out and get away unseen. If it was Lenning, then he would miss him, and would have to begin his search all over.
Another thought came to him, as he moved slowly upon the laboratory, and Frank was surprised that it had not occurred to him before. A night watchman, moving about among those dark tanks, would certainly carry a lantern. Frank had been stumbling blindly around the tanks, hunting for Lenning, when, if he had considered the matter thoroughly38, he need only have looked for a bobbing light.
“I must be getting ‘dippy’ over this Lenning business,” he reflected. “I’m making mysteries where there are only commonplace, every-night events. Probably I’ll find Lenning sitting in a chair in front of the laboratory, guarding the bullion as comfortably as possible.”
He moved on to the side of the laboratory with considerable confidence. At one of the dark windows he halted and peered into the interior of the structure. A quick breath escaped his lips.
What he saw, in the black gloom of the laboratory, was a long, quivering shaft39 of light. It crossed the big room, coming from a mass of shadow and trembling over some object whose nature Frank was not able to determine. But a thrill of apprehension40 ran through him.
Surely that penciled gleam was from a bull’s-eye lantern! An honest watchman never made use of such a light—or, at least, no watchman whose duty kept him around a lot of big cyanide tanks!
With this for a starting point, Frank’s thoughts took a dizzy and horrifying41 leap into a tangle42 of conjectures43.
123
Perhaps Lenning was working at the safe! It might be that he had asked for that job at the mine with the sole idea of getting a chance at the bullion! And it was Frank who had recommended the fellow to Mr. Bradlaugh!
A sick feeling ran through the lad as he stood leaning against the wall and looking into the laboratory. Then, against these forbidding fancies, he marshaled all that Lenning had said to him that afternoon—how he was going to do the square thing, and that Merry would never have cause to regret befriending him.
It did not seem possible that——
Frank’s reflections were suddenly interrupted. Above the mutterings of the stamps, his keen ear caught a crunch44 of sand behind him. Alarmed, he started to whirl around; but, before he could turn, he was caught by the shoulders and thrown violently sideways. As he fell, his head crashed against the stone sill of the window, and he remembered nothing more. Blank darkness rolled over him, suddenly and completely.
