“Yes, that’s Sim Reeves’ rig, of the town livery stable, and he’s a good-hearted man, so I guess he loaned the wagon and driver just to give the poor kids a little outing on this fine Saturday afternoon. But I wish they’d hurry and get that wagon moving, for as sure as you live there’s a car loaded with stone starting slowly down the incline now.”

“Yes, you’re right,” said Hugh, thrilled by the thought of a catastrophe overtaking those innocents below.

“The man on it can’t see that there’s anything wrong down at the crossing,” cried Billy in great excitement. “He will soon, and put on the brakes.”

While Billy continued to keep his eyes glued on the coming car, Hugh on the other hand allowed his gaze to roam around. He even took several steps over to one side as though measuring the distance separating him from the track at a certain place.

All at once Billy gave a shriek.

“Hugh! look! look! the brake’s given way! There goes the man jumping for his life, and listen to the children screaming, will you? Hugh, can’t we do something? It’ll get going faster and faster, and—oh! Hugh, the poor, poor kids!”

CHAPTER II.
WHAT PRESENCE OF MIND MEANT.

While Billy Worth was talking Hugh was acting. That seemed to be a chronic habit with the scout master. An emergency never caused him to quail, and as a rule he could be depended on to do the right thing at the right time.

That was where the benefit of his preliminary look around came in. The very second that he discovered the accident to the descending stone-laden flat-car, Hugh knew that it was up to him to do something in order to save those imperiled orphans from a terrible calamity.

The car was on a run of the track that was very nearly level, so that as yet it had not attained the very great velocity sure to follow, after it came over the crown of the rise, just above where the two boys stood.
