Derrick Sterling: A Story of the Mines

by Kirk Munroe

So Derrick's plan was discussed in all its details, and before they separated that night it was adopted.

In order that the mistake made by Derrick in his slight alteration of the plan of the old workings, as shown in his tracing, may be understood, a few words of explanation are necessary.

The old drift-mouth, that he had discovered almost hidden beneath a tangle of vines and bushes, was on a mountain side above a deep valley. Farther down was the mouth of a second drift, which he had not discovered, and knew nothing of. On the opposite side of the mountain was another valley, the bottom of which was on about the same level as the higher of these drifts. The old workings ran from them through the mountain, and under this valley in which the present colliery was located.

When the gangway from the upper of the two drifts had been opened as far as the valley, the vein that it followed took a sudden dip. The gangway was in consequence changed into a slope, which finally led into the workings beneath. Some time after they had been abandoned a great "break" or cave-in of the ground above there had occurred at the edge of the valley, and by it an opening was made into the lower set of workings. It was on the opposite side of the valley from this break that the new workings were now being pushed; and somewhere between it and them was the old air-shaft and the chamber that the Mollies had selected as their place of secret meeting.

Now Derrick had got hold of a plan of the lower set of these old workings which he knew nothing of, and thought it was a plan of the upper set, which in reality only extended to the edge of the valley. He knew that the upper drift-mouth was on about the same level as the top of the old air-shaft, and thought he had a plan showing that the two were connected. He reasoned that by entering the old gangway at the break, and following it under the valley, they would not only save distance, but would be conducted directly to the top of the air-shaft which they wished to reach. By the joining of those two lines at the blurred place on the plan it was made to conform so perfectly to this theory that he felt satisfied his conclusions were correct, and consequently made his confident statements to Mr. Jones.

The latter had been connected with the Raven Brook Colliery but a few months, and knew nothing of its old and abandoned workings, not yet having found time to study their plans or explore them. He did know, however, that Mr. Sterling had been one of the company's most trusted engineers, and that Derrick had long been interested in poring over and tracing his father's plans of these very workings. When, therefore, he had carefully examined the tracing that the boy had made, and now assured him was an exact copy of the original plan, and found that it showed a system of galleries by which the top of the air-shaft might be gained from the break, he had no hesitation in saying that they would make the attempt to reach it from that direction. Had he sent for the original plan he would have quickly discovered Derrick's error. He thought of doing this, but did not, for fear of wounding the lad's feelings by appearing to mistrust him.

It was arranged between them that Mr. Jones should leave the village on the afternoon of the 27th, as though bound on some distant expedition, and have it understood that he might possibly be absent all night. An hour before sundown he was to be at the break, prepared to explore the old gangway to which it gave entrance. Here Derrick was to meet him, after having left the mine an hour earlier than usual, gone home for supper, and told his mother that he should be out late on some business for the mine boss.

This plan was successfully followed, without suspicion being aroused, and the young mine boss met his boy companion at the appointed time and place. They both had safety-lamps, and each carried a small can of oil, for they did not know how long they might have to remain in the mine.

In the break they found a rickety ladder that had been placed there for the use of the village children, who were accustomed to come here with baskets, and in a small way mine coal for home use from the sides of the old gangway. Descending this, they lighted their lamps at the bottom, and entering the black opening began to follow the path marked out on Derrick's tracing.

For some distance the way was comparatively smooth, and they made rapid progress. Then they began to encounter various obstacles. Here a mass of rock had fallen from the roof, and they must clamber over it. In another place a quantity of waste material had so dammed a ditch that for nearly a quarter of a mile the gangway was flooded with cold, black water, through which they had to wade. It was above their knees, and, filling their rubber boots, made them so heavy as to greatly impede their progress. In several places where the old timber props had rotted out, such masses of rubbish choked the gangway that they were compelled to crawl on their hands and knees for long distances through the low spaces that were still left. Once they were on the point of turning back, but animated by the importance of their errand they kept on, cheering each other with the thought that they would not be obliged to come back this same way in order to leave the mine.
