Harris attempted to fling Frank beneath this bar, where he would be struck and crushed.
The villain nearly succeeded, so swift and savage was his attack.
Frank realized that the purpose of the wretch was to fling him into the machinery, and he braced himself to resist as quickly as possible.
Shouts of consternation broke from the engineer and his assistant.

They sprang forward to seize Harris and help Frank.
But, before they could interfere, Frank broke the hold of his enemy, forced him back and struck him a terrible blow between the eyes felling him instantly.
Merriwell stood over Harris, his hands clenched his eyes gleaming.
"Get up!" he cried.

"Get up you dog! I can't strike you when you are down, and I'd give a hundred dollars to hit you just once more!" But Harris did not get up.

He realized that his second attempt had failed, and he stood in awe of Frank's terrible fists.

He looked up at those gleaming eyes, and turned away quickly, feeling a sudden great fear.
Did Frank Merriwell bear a charmed life?
Surely it seemed that way to Harris just then.
