"It's a lie!" exploded the boss. "You—you did it on purpose!"

With a growl of rage the Pole leaped into the pit, intending to reach the plank. Steve hopped out on the opposite side and Kalinski fell on his face in the hot cinders.

Bob uttered a howl of delight. This was much better than he had hoped for. Watski was getting his punishment without the boys having to administer it, and he was getting it properly, judging from his yells.

By this time several men had gathered about the pit, making no effort to hide their delight at the Pole's predicament.

Rush hopped down to the plank, leaving his shovel on the ground. He grabbed Kalinski by the shirt collar and the seat of the trousers, and, without any apparent effort, tossed the man out of the pit. The spectators gazed at the young man in amazement. His great strength was a marvel to them.

"Oh, why didn't you let him toast some more?" grumbled Bob. "He hasn't had enough yet. I tell you, he's only half baked."

"Take your shovel and get in here. We shall be in trouble the first thing we know," warned Rush.

Bob obeyed reluctantly. He limped a little as he walked toward the cinder pit, for his legs pained him and there were blisters on his feet where the hot cinders and slag had burned through the shoes. Besides, he felt that he had not done his duty.

"Did you hear Watski give you the lie, Steve?"

"Yes, I heard," answered Rush, beginning to throw out cinders again. "He isn't worth bothering with. Let him alone. We cannot afford to have any fights at the beginning. I was in hopes things would run along smoothly."

Foley leaned over the edge of the pit.

"I'll report you both; I'll have you fined!" he growled.

"Go on!" jeered Rush. "Report the other man. If you don't, I will."

"Let me at him! Let me at him!" yelled Kalinski, starting for the pit. "I'll rub his nose in the hot slag, I will! I'll show him he can't throw hot cinders in my face. Git out of my way!"

CHAPTER IV

LAYING HANDS ON THE BOSS

IT was Foley's place to order the pit boss to let the boys alone and attend to his own business. Instead, Foley turned and walked away. He did not go far, however. He made his way to one of the open-hearth furnaces, where, unobserved, he peered around the corner of the red-hot pile of brick.

Rush saw that an encounter was unavoidable. He was sorry, but he decided quickly to avoid coming to blows if possible.

Kalinski had stooped over to pick up a shovel. In his rage he was going to attack the boys with it. Steve was out of the pit in a flash.

"Keep out of this, Bob, unless the others mix in. I'll take care of that fellow."

When Watski straightened up he found the Iron Boy standing over him with a pleasant smile on his face.

"I wouldn't do that, were I in your place, Kalinski. I tell you it was an accident, and I am sorry I threw the cinders over you. I give you my word that it was an accident."

Watski dropped his shovel, and uttering a yell of rage, struck at Steve. The blow, had it reached its mark, would have knocked Rush backward into the hot cinder pit. He dodged the blow, however; then suddenly Watski Kalinski found his wrists in a grip that made him writhe. The Iron Boy's thumbs were pressing on sensitive nerves.

"Ouch! Ouch!" howled the Pole.

Foley, in his wonder, forgot to hide himself. He stepped from the protection of the furnace.

"Leggo my wrists! Leggo, I tell you!"

"Will you behave yourself if I——"

"I'll knock your head—ouch!"

The tears were actually running from the eyes of the pit boss. He was suffering great pain. But he got no sympathy from the mill hands who had gathered about. They were laughing and jeering at him, not especially because they sided with Rush, whom they did not know, but because Kalinski was not popular among them.

At this juncture Bill Foley came running forward. He saw that his pit boss was getting the worst of it, and that Rush would soon gain the sympathy of the crowd. He did not wish this to happen. Had it been the other way Foley would have been perfectly satisfied.

The furnace foreman dashed around the pit, headed for the humiliated boss. Jarvis saw him coming. Bob stepped in front of Foley.

"What are you going to do?" demanded the lad.

"Get out of my way before I hurt you!"

"And you keep out of this, or I'm likely to forget myself and hurt you. You know it wouldn't look well to have the foreman licked by one of his men," grinned Jarvis.

Foley gazed at the Iron Boy in astonishment. All at once he raised his foot, delivering a vicious kick. The foreman never quite understood how it happened, but the next second he found himself falling backwards into the pit, while the mill hands set up a roar.

Jarvis had been on his guard. When the kick was delivered, he caught the ankle of the foreman, giving it a quick jerk that threw the fellow off his balance. There could be but one result. Bill toppled over backwards, landing on his head in the pit.

"Get him out of there! He'll burn to death, Bob," warned Rush.

Bob helped the foreman out, but with reluctance.

"It would serve you right if you did burn. But don't you try any of your funny business on me again. You won't get off so easily if you try it on another time."

"Kalinski, do you think you can let us alone if I release you now?" questioned Steve.

The Pole did not answer, but if there ever was murder in a man's eyes it was in Kalinski's. Steve put on a little harder pressure.

"Yes, yes; leggo! I don't want anything to do with you. I——"

Rush released the man instantly. At first the Pole acted as though he was about to spring upon his remarkable young antagonist. He seemed to think better of it, however, after a glance into the unsympathetic faces about him, then into the smiling face of Steve Rush.

"Will you go to work, or must I throw you out of the mill!" snarled Kalinski.

"We shall be glad to go to work if you will let us alone. I wonder what the superintendent would say if he happened along about this time?"

"I shall fine both of you two days' pay," announced Foley, making a memorandum in a soot-soiled memorandum book.

"Very well, sir. That is your privilege. It is ours to protest, if we think best, which is not saying that we shall. We have been used most disgracefully, and——"

"You didn't think of that when you got me into trouble, did you?" sneered the foreman.

"So that is where the shoe pinches, is it? I begin to understand. You propose to get even with us? Well, all I have to say is that I should advise you not to try it. We have come here to work, and at our own request. If you become unbearable I warn you we are perfectly able to take care of ourselves, and we shall do so. We don't propose to submit to any insults from you or any one else, Bill Foley."

"Just put that in your pipe and smoke it!" chuckled Bob.

Steve was at work again. Jarvis slowly followed his companion to the pit, where both lads stood on the plank and shoveled out cinders. They gave no further heed to the foreman or the pit boss. The latter two had drawn back some little distance, where Kalinski was gesticulating and talking to Foley with considerable emphasis.

In a little while the shovelers had gotten down to where the pit was aglow with coals. The plank beneath their feet began to blaze up, the smoke getting into their mouths and noses, setting the lads to sneezing.

"I am going to get out of here," announced
