By this time they were within the house, and as Mrs. Sterling hastened to make ready the supper she had saved for Derrick, he dropped into a chair utterly exhausted. He might well be exhausted, for what he had passed through and suffered since leaving home that morning could not have been borne by a boy of weaker constitution or less strength of will. He was greatly revived by two cups of strong tea and the food set before him. After satisfying his hunger he went to his own room, and took a bath in water as hot as he could bear it, and washed his cuts and bruises with white castile-soap, a piece of which Mrs. Sterling always managed to keep on hand for such emergencies. It was fortunate for her peace of mind that the fond mother did not see the cruel bruises that covered her boy's body from head to foot. The bath refreshed him so much, and so loosened the joints that were beginning to feel very stiff and painful, that Derrick believed he was able, before going to bed, to perform the one duty still remaining to be done. Mrs. Sterling thought he had gone to bed, and was greatly surprised to see him come from his room fully dressed. When he told her that he must go out again to deliver an important message to the mine boss, she begged him to wait until morning, or at least to let her carry it for him. Assuring her that it was absolutely necessary that he should deliver the message himself that very night, and saying that he would be back within an hour, Derrick kissed his mother and went out. On the street he met with but one person, a miner hurrying towards the slope, to whom he did not speak, and who he thought did not recognize him. Mr. Jones had closed his house for the night, and was about to retire, when he was startled by a knock at the outer door. Recent events had rendered him so suspicious and cautious that he stepped to his desk and took from it a revolver, which he held in his hand as he stood near the door, and without opening it, called out, "Who's there? and what do you want at this time of night?" As softly as he could, and yet make himself heard, Derrick answered, "It is I, sir, Derrick Sterling, and I have got something important to tell you." At this answer a man who had stolen up behind Derrick, unperceived by him in the darkness, slipped away with noiseless but hurried footsteps. "Is anybody with you?" demanded the mine boss, without opening the door. "No, sir; I am all alone." Then the door was cautiously opened, Derrick was bidden to step inside quickly, and it was immediately closed again and bolted. Leading the way into the library, the mine boss said, not unkindly, but somewhat impatiently, "Well, Sterling, what brings you here at this time of night? working boys should be in bed and asleep before this."
