He had not had time to make the thrust with the steel bar.

Instead, as he wheeled, he raised it above his head, drawing back in
an attitude of guard.

As he did so, a vile oath escaped Truax's lips.

"Put that bar down!" commanded Jack Benson, standing unflinchingly
before the angry rascal.

"I'll put it down on your head, if you don't get out of here!" snarled
the wretch.

"Put it down, and consider yourself off duty here, for good and all,"
insisted Jack.

"Are you going to get out of here, or shall I brain you?" screamed
Truax, his face working in the height of his passion.

"Neither," retorted Captain Jack, coolly. "I command here, and you know.
Put that bar down, and leave the engine room."

"Come and take the bar from me--if you dare!" taunted the fellow, a
more wicked gleam flashing in his eyes.

"Hal!" called Jack, sharply.

"Aye!"

"Call two or three of the cadets down here. Don't make any noise about
it."

This order was called without Benson's turning his head. He still stood
facing the sneak while Hal sped away.

"Now, I've got you alone!" gloated Truax. "I'll finish you!"

A scornful smile curled Jack's lips as he gazed steadily back at his foe.

"Truax, you're a coward, as well as a sneak."

"I am--eh?"

With another nasty oath Truax stepped quickly forward, the steel bar
upraised.

He took but one step, however, for Captain Jack Benson had not retreated
an inch.

Nor did Jack have his hands up in an attitude of guard.

"Are you going to put that bar down, Truax?" the young skipper demanded,
in a voice that betrayed not a tremor.

"No."

"Then you'll have to make good in a moment, for we're going to attack
you."

"Bah! I can stave in two or three heads before any number of you could
stop me," sneered the fellow, in an ugly voice.

"You could, but you won't dare."

"I won't?"

"Not you!"

At that instant rapid steps were heard. Hal Hastings returned with
three of the midshipmen, behind them Williamson trying to crowd his way
into the scene.

"Just tell us what you want, Mr. Benson," proposed Cadet Merriam,
amiably.

"This fellow has been 'doping' our engines," announced Captain Jack.
"And now he's threatening to stand us off. We'll close in on him from
both sides. If he tries to use that steel bar on any of us--"

"If he does, he'll curse his unlucky star," declared Midshipman Merriam.
"Come on, gentlemen. We'll show him some of the Navy football tactics!"
