All the other contract drifts had been found to be working regularly, so it was reasonable that the entire shortage might be charged to Spooner.

As a matter of fact, this shortage tallied very closely with the figures that the tally-man had given to the superintendent.

When the contractor returned to his drift he was more subdued than any of his regular shift had ever before seen him. They could not understand the sudden change. There was one there, however, who did understand.

That one was Bob Jarvis. Bob was leaning against the "sh.o.r.e" just outside of the vein the men were working. He was doing nothing in particular.

Some moments pa.s.sed before Spooner discovered this.

"Get in there, you, before I shove you in! Get hold of a shovel! What do you think I'm paying you for? What are you trying to do--hold up the wall? The lagging will do that without your help. Get to work."

"I am working," answered Bob coolly, making no effort to obey the order of the contractor.

"You are working, eh?"

"Yes."

"May I inquire what you are working at?"

"Yes, I'm working for the company. My particular business at this moment is watching you."

"Watching me?"

"Yes, sir; I am here to check you up. I am not working for you to-day.

As I said, I am working for the company. Don't let me disturb you, sir.

I'll try not to get in the way."

"Do you know why you are doing this?"

"Yes; because I am ordered to do so."

"Is that all you know?"

"It may be, and then again it may not be."

With a growl, Spooner turned and began to abuse his men, while Bob remained leaning against the wall, checking each car as it was filled.

In the meantime, when Marvin returned to his station on the level below, he stepped to the tally-board and relieved the man who had been placed there to act during the regular man's absence.

As Marvin was looking over the boards Steve stepped up, touching him on the shoulder. The tally-man's face flushed angrily.

"What do you want?"

"Merely to say to you that I have had orders to check you up, to see that you check every car properly."

"I won't stand it. I'll----"

Steve shrugged his shoulders.

"That is a matter with which I have no concern. You will have to fight that out with the superintendent. I shall obey my orders and it will be better for you, I should imagine, to submit without trying to make matters uncomfortable for me. I shall do what I have been told to do, just the same. When a train draws up you will plug only when you see that I am looking at the board, please. I'll dump the cars after you have done that and I shall know if you have moved the plugs when I am not looking."

Marvin's face twitched nervously, but he made no reply.

There was nothing of triumph in Steve's att.i.tude. The lad was attending to business to the best of his ability. He discovered, after a time, that Marvin was watching him narrowly. As he watched, the tally-man's face grew blacker and blacker.

"I wonder if he suspects?" thought Rush.

As a matter of fact, Marvin was beginning to see light. At noon the tally-man hurried away, after sulkily asking Steve to watch the tally-board. First, however, the man made a memorandum of the tally, so that Steve could not change it without Marvin's being aware of the fact.

The lad pretended not to have observed this, but a quiet smile hovered about the corners of his mouth as he laid out his lunch on a clean, white napkin on the bench beside him.

Instead of going up in the cage, Marvin hastily climbed a ladder to the sub-level, where he waited for Spooner to come out.

"Well, what is it?" demanded the contractor in a surly tone.

"I've got wise to something. Where can we talk?"

"Come over in the drift here. There's no one near by."

The men slipped into a dead drift, extinguished their candles and engaged in earnest conversation.

Bob Jarvis' shrewd eyes had observed the actions of the men. He was sitting in the Spooner contract eating his lunch, but they had not noticed him.

"I wish I could find out what they are talking about," he muttered. "But I am not a spy. I don't know that I care particularly. I'll tell Steve, for I have an idea there is mischief in the air. There they go down the level."

The two men climbed down the ladder to the main level. A few minutes later Steve saw Spooner alone, sauntering along the tracks. When the contractor reached the chute he halted, peering over at the lad as if he had just discovered him.

"h.e.l.lo, Rush," he greeted, turning and coming over to where Steve was sitting.

"Good afternoon."

Spooner sat down on the bench, and, for a moment or two, nothing was said, Steve continuing with his lunch as indifferently as if the contractor had not been there.

"So you're the sneak who gave me away, are you?" demanded Spooner, turning upon the lad savagely.

Steve eyed the contractor calmly.

"Am I?"

"You are!"

"I may be the man, and in fact I will admit that I was instrumental in exposing your crookedness, but I am not a sneak. It strikes me that you have laid yourself open to being called one."

The man's face turned white with anger. He opened and closed his fingers, with difficulty restraining himself from fastening them upon the calm-faced boy beside him. Steve munched his food steadily, but he was watching the man narrowly.

"I--I'll be even with you for that, you sneaking cur!" shouted Spooner.

"Yes, I'll be even with you!"

"I wouldn't threaten, were I in your place. If anything should happen to me you might be accused, you know," answered Rush in a tantalizing tone.

"What do you propose to do to me?"

Spooner leaped up and shook his fist under the Iron Boy's nose. The latter did not flinch.
