At this Derrick started; he had not realized that he was in any particular danger.

"Do you think, sir, they would pay any attention to a boy like me?" he asked.

"I certainly do," replied the mine boss. "They would pay attention to anybody or anything that stood in their way, or seemed likely to interfere with their plans. I am afraid, from what Job Taskar said the other day, that they consider your presence in the mine as dangerous to them. I am sorry that my liking for you, and efforts to promote your interests, should have placed you in such an unpleasant position. If you like I will try and get you a place as errand boy in the main office of the company, where you will be in no danger."

"Oh, no, sir!" exclaimed Derrick. "Please don't think of such a thing. I'd rather take my chances with the Mollies in the mine than go into an office. There I should never be anything but a clerk; while here I may some day become an engineer, as my father was. Don't you think I may, sir?"

"Yes," answered the other, smiling at the boy's earnestness, "I think any boy of ordinary intelligence and blessed with good health can in time occupy any position he chooses, if he directs his whole energy in that direction, and makes up his mind that no obstacle shall turn him from it."

"I have made a beginning, sir," said Derrick, much encouraged by these words from one who was so greatly his superior in age, knowledge, and position, and whose opinion he valued so highly.

"Have you?" asked the mine boss, with a kindly interest. "In what way?"

"I am studying my father's books, and trying to work out problems from some old plans I found among his papers. One of them is a plan of the very oldest workings of this mine, and I have brought a tracing of a part of it to show you."

"Very good," said Mr. Jones, glancing at the tracing carelessly. "I have no doubt that in time you will become a famous engineer."

Although this was spoken kindly enough, it was evident that the speaker's thoughts were far away, probably trying to devise some means for being present at the approaching meeting in the mine.
