When they had left the breaker, Derrick said, "How would you like to go down into the mine, Paul, and be a door-tender, very near where I work, and get twice as much money as you can make in the breaker?"

"Of course I should like it," answered Paul, gravely; "but I don't think they want a cripple like me down there."

"Yes, they do want just exactly such a fellow as you are; they found out last night what you could do in a mine. Mr. Jones says that if you want to you can go down with me to-morrow morning, and begin at once without waiting for the end of the month. You are to go with me to the store this evening for your mine cap, lamp, and boots. See, here's the order for them."

Paul stared at the order for a moment as though he could not believe it was real. Then exclaiming, "Oh goody, Derrick! I'm so glad to get out of that hateful, back-aching breaker," he gave a funny little twirl of his body around his crutch, which was his way of expressing great joy.

Derrick shared this joy equally with Paul, and to see them one would have supposed they had just come into fortunes at least. To a stranger such rejoicings over an offer of monotonous work down in the blackness of a coal mine would have seemed absurd, but if he had ever been a breaker boy he could have fully sympathized with them.

The two boys were standing beside the check-board, near the mouth of the slope, and after their rejoicings had somewhat subsided Derrick said, "Let's see who's sent up the most to-day."

The check-board was something like the small black-board that hangs behind the teacher's desk in a school-room. It was provided with several rows of pegs, on which hung a number of wooden tags. Each of these tags, or checks, had cut into it the initials or private mark of the miner to whom it belonged. When a miner working in the underground breasts or chambers filled a car with coal and started it on its way to the slope, he hung on it one of his checks. When the same car reached the top of the slope the "check boss" stationed there took the check from it and hung it in its proper place on the check-board. At the end of working-hours the number of checks thus hung up for each miner was counted, and the same number of car-loads of coal credited to him.

Acting on Derrick's suggestion, the boys turned to the check-board, and quickly saw that there were more checks marked M. T. than anything else.

"Why, Monk Tooley has got the most by three loads!" exclaimed Derrick, counting them.

"He must have worked all through lunch-hour, and like a mule at that. I wonder what's got into him?"
