Out from the depths of the forest overhanging the track ahead had sprung a score or more of armed men.

Expecting the terrible collision they had planned, they had leaped upon the track in front of the oncoming train, flourishing their weapons and uttering wild yells of triumph.

It was a moment to Jack North which meant all to him. To stop the train was to throw it into the hands of his enemies; to keep on was like rushing into the very jaws of destruction. The commotion still raging at the rear of the train, the exulting fiends in the pathway ahead, and not less the silent but ominous bowlder on the gleaming track foretold the end, let him act as he might.

With that unerring precision of gaze which never failed him, Jack saw that the stone lay at such a place and in such a position that the engine would not strike it squarely, but sidewise, as it swept around the curve. To make it more favorable the obstruction, as has been said, lay on the right, or outside rail.

Had it been on the opposite one all would have been changed to a terrible certainty.

There was no cowcatcher in front, similar to those seen on the engines in this country, but there was a heavy iron fender in its stead, which presented a square defense. This bar would strike the rock below midweight, and in such an oblique manner that he believed the barrier would be hurled from the track without derailing the engine.

Jack understood that he was taking a fearful risk, but with all these favoring circumstances it could not be more disastrous than to stop and to fall easy victims to the bush-raiders and their allies.

These thoughts flashed through his mind and he resolved to keep on at all hazards. Thus he let on all the steam in reserve and stood grimly at his post.

The engine obeyed like a living creature. It gave a mighty plunge forward and dashed upon the ponderous barrier disputing its advance.

The suspense was of brief duration, but Jack’s thoughts flew fast and far. He realized that if the engine failed to clear the track it would be all over with him in a moment.
