There was a lot of drinking, gambling, and quarrelling going on, and Sergeant Silk had come along in the interests of law and order.

The mere presence of a member of the North-West Mounted Police, with his conspicuous red tunic and his bandolier of brightly-polished cartridges, had almost a magical effect in preserving peace. His duties were light, and he went about the thronged encampment as a friendly and welcome visitor rather than as a stern and dreaded representative of the law.

So little had he expected to be called upon to exercise his authority that he had brought young Percy Rapson as his companion—Percy Rapson, the aristocratic English boy, who had been sent out to Canada to learn farming on Rattlesnake Ranch, and who had now sought variety from his tuition in agriculture by accompanying his friend on an easy patrol to witness the wonders of a great logging camp at work.

On the second morning of their arrival at Stone Pine they had left their mounts in stable and strolled down to the waterside to see if the workers had yet located the key logs, which held the vast mass of floating timber locked in the bend of the river.

To Percy Rapson the sight had all the interest of novelty, and he lingered, watching, in the hope of seeing the jam break loose. The breast of the barrier of logs rose to a height of some thirty feet above the water's level, in a confused pile. The giant tree trunks, flung into a hopeless tangle, were becoming with every hour more tightly crushed by the mighty pressure of the crowded logs in the rear.

As far back as the eye could see the surface of the river was hidden under its brown pavement of drifting timber.

On the great jam itself men were at work with their peavies industriously picking at the huge logs, heaving and rolling them downward into the rapids beyond, where they might be caught and swept away by the current.

But the key logs, which held the main pile plugged in its position, had not yet been found, and even an occasional charge of dynamite had so far failed to stir the barrier.
