"Jake," he said, "I want you to go to the Landing and see that the Mappin people send up the plant Watson expects as soon as it's off the cars. I shall stay here a while and try to learn something about my business."
"Well," drawled Carnally with signs of amusement, "there is a good deal to learn."
He set off early the next morning, and Andrew, putting on a suit of overalls, went down into the mine and insisted on being given practical instruction in the use of the drill. It was a painful process: he was forced to kneel on sharp stones and sometimes in water while he held the steel bar, which jarred his hands when his companion struck it. Nor did he find the work easier when he came to strike, standing in a cramped position without room to swing the hammer, his eyes fixed upon the end of the drill, which must be squarely hit. To miss might result in the other man's knuckles being smashed. The inch of metal which glimmered in the lamplight formed a perplexing mark. Andrew had an accurate eye, however, and did not often miss; and he forgave his instructor for hitting him on the wrist, though this necessitated its being bound up for several days. He learned the quick twist of the drill which brings the cutting edge to bear, and how to wedge up the roof by setting a prop, sawed a little too long for the position, slantwise beneath a beam and hammering it straight; and then he turned his attention to more advanced subjects.
"Watson," he commented one morning, "this mine strikes me as being badly arranged. The best ore's on the lower level, the lode dips, and having the shaft underground must give you extra trouble in getting the stone and water out."
"It does," Watson assented. "You want to remember that we took over Rain Bluff after work had been begun, and the fellows who locate these bush mines often don't know much about their job. If they think the ore's there, they start to get it out the best way they can. I've seen that we'll have to drive a lower adit right in from outside sooner or later, but I'm shy of the expense."
"It seems to me that the money will be profitably spent," Andrew said when they had discussed it for a while. "You'll get it back by saving labor and pumping, while the extra cost you're put to now would probably increase. You'd better start the work at once; I'll be responsible."
Watson was beginning to understand that the resident director possessed abilities which he had by no means suspected at first. He did as he was told, and for the next few weeks Andrew was pleasantly occupied. He learned to nip detonators on to fuses, and how a stick of giant-powder should be inserted into a firing hole. He studied the lines of cleavage in the rock, calculated the cost in labor and explosives of the stone brought down, and found it all interesting. As a matter of fact, it was the first time he had seriously interested himself in anything except sport, and there was encouragement in feeling that he possessed some useful powers. Watson spoke to him as to one who could understand; the miners did not seem to notice his clumsiness. He had expected some banter from them, but none was offered, and he remembered that it was Leonard and his relatives who had shown an amused disbelief in his capabilities.
One day he descended to the lower level, where the men were having trouble in the manager's absence. A number of lamps were burning and the place looked wetter than usual in the unsteady light. Water trickled down the end wall, the rows of props were dripping, and the half-naked men splashed through pools when they moved to and fro. They were feverishly busy: one group building a massive pillar, others putting up fresh props; only two or three were breaking out ore at the working face. Then Carnally came toward him, and his wet face showed tense and anxious in the light of Andrew's lamp.
"The blamed roof's very shaky," he said. "We've had two ugly cave-ins. I wish Watson was back. And I'm getting scared about the water; expect we're tapping a tank-pot in the hill, but there's nothing to help us in locating it. You might give the boys a hand with the pillar."
Andrew stripped to shirt and overall trousers, and hurried toward the spot. He saw that the men needed help, for the cracked roof was bulging downward ominously and there were several heaps of freshly fallen stones. They were constructing a square frame of logs, crossed at the ends, and filling it in with broken rock as fast as they could; but there remained a wide gap between its top and the roof it was meant to support. For an hour he worked savagely, wet with falling water and dripping with perspiration, passing up heavy beams and stones to the men who laid them in place. He grew breathless and tore his hand, but the flakes of rock which fell at intervals urged him on. Once or twice there was a crash farther down the tunnel and he saw shadowy figures scatter and others run in with props, but for the most part he fixed his attention on his task, because it looked as if they had no time to lose. When a gush of water flowing down the heading splashed about his boots, he called Carnally.
"Is this tunnel going to cave in?" he asked.
"That's more than I can tell," Carnally replied. "We may be able to shore her up, but if it's not done soon, the chances of her crushing in are steep."
"I see," said Andrew, and turned to his companions. "Boys, I'll stand for a ten-dollar bonus if this job's finished in half an hour."
One of them laughed, but there was no other response and they did not seem to increase their exertions much. This suggested that they had been doing their utmost already, with a clear recognition of the risk they ran. Their pay was good, but something besides their interest urged them to keep the mine open. These were men who would not easily be beaten by inpouring water or crushing rock: they had braced themselves for a grapple with their treacherous natural foes.
Andrew, however, was feeling the strain. His injured hand was painful, the stones he had to lift were heavy, his arms and back ached; but he meant to hold out, for the gap between roof and pillar was getting narrow. He had raised a ponderous piece of rock and was holding it up to a man who reached for it when there was a smashing sound above and a dark mass rushed past him. The tunnel echoed with a crash, and Andrew received a violent blow on his head. The pain of it turned him dizzy, but he heard a clamor of voices and harsh warning cries. They were followed by a smashing of timber; he saw two or three props crush in; and then half the lights went out and he felt the water washing past his boots.
The next moment his legs were wet, and he set off for the shaft, knee-deep in a rushing flood. There was a confused uproar behind him: stones falling, timber breaking; and then the last of the lamps went out. It cost him an effort to keep his head. Hurrying men jostled him; he struck his feet against sharp stones and was thankful that he did not fall. While he battled with a growing horror, he made for the feeble glimmer which marked the bottom of the shaft. It was a short distance, and he presently stood in the gathering water among a group of half-seen men, watching one being slowly drawn up toward the brighter light above. Another was hurriedly climbing the ladder, while a comrade waited to follow as soon as he was high enough. Then Andrew felt a hand on his arm.
"I was looking for you," Carnally said. "You had better get up. Take the rope as soon as it drops."
Andrew felt a strong desire to do so, but he mastered it.
"No," he returned calmly; "not yet. In a sense, it's my mine; I must see the boys out."
A man near him raised a shout.
"What's the matter with the winch! Can't you heave on it?"
A deepening rush of water swirled about them and there were sharp cries:
"You above, get on to the handles! When's that rope coming? She ought to carry two!"
A man clutched at the rope, which fell among them but when another grasped it Andrew interfered.
"Steady, boys!" he said. "The winch won't lift you both. Being heaved up is too slow. Tell them to make the rope fast, and then climb; it's strong enough to carry two or three."
There was a growl of approval; instructions were shouted up; and while the water rapidly deepened, the group at the foot of the shaft decreased. Andrew, however, was above his waist before he clutched the ladder, while Carnally seized the rope. There was a man above him whose feet he must avoid, and he felt the timber shake, but it was with vast
