Accordingly, after telling the old factor not to worry as they meant to start the Mounties on the way to the scene of the outrage with the least possible delay, both he and Perk pressed the hand of the wounded man and passed outside, followed by the admiring Birdseye who would never cease from sounding the praises of Jack’s surgical work.

The next thing to concern the pals was in line with their expected hop-off. Would it be possible to make the jump from such a wretched field, with its many bumpy spots calculated to cause the moving craft to wobble fiercely?

Together they walked over the anticipated course, examining the nature of the ground, to toss aside, when possible, such rocks as threatened to jar them seriously. When finally they had thus surveyed the entire stretch, Jack pronounced the decision in which his comrade concurred—that although they would assume some risks, still in the course of their experiences in the past both of them had successfully climbed out of even worse traps than the one they were now up against.

So they went aboard, watched by every living creature about the post saving Old Jimmy himself. As usual Jack checked his dials and the motor with a skill that only comes from long experience added to that peculiar air-minded wizardry possessed by just a few pilots, like Lindbergh.

“Okay Boss?” inquired Perk, picking up the ear-phones as if ready to adjust them to his head because it might be necessary for them to exchange remarks soon after they started, and according to Perk’s mind it was very essential they should be prepared.

“Here we go!” came the answer, upon which the motor took hold and the big ship started forward, followed by the cheers of Birdseye and his fellows although these grew fainter as the amphibian went bumping along, increasing its pace as Jack saw fit to pull back the stick against his breast, until just as they finally lost contact with the ground, the racket of motor and propeller smothered all other sounds completely.

They were off to a safe start and no damage done. Perk settled down in his seat ready to take up his accustomed duties although he felt convinced everything was in apple-pie condition aboard the boat.

Their course was a point off due north, Perk having coached his mate with regard to that important matter. Besides, from their lofty lookout point it would soon be easy enough to discern the post known as Fort Laney for it lay on one of the small rivers that emptied into the Mackenzie, itself starting in Great Slave Lake.

Perk could not but remark upon the changes that were gradually taking place in the country the further north they went. This struck him as wonderful, for although he had spent several years in this region, never before had he been privileged to take such a sweeping survey of the landscape as on the present occasion for heretofore he had been upon the ground where rocky mountains and all manner of huge obstacles obstructed the view and restricted the vision.

He could figure out just about in what quarter the Peace River lay, a place he had good occasion to remember since one of the most stirring adventures connected with his service in the Mounties had taken place on its banks. So too, was he able to look in the direction whence must lie the town of Simpson, on the great Mackenzie, some hundred miles or more distant as the crow flies. There was also Great Bear Lake, another body of water he had looked upon, and which must stir up other vivid memories for events in which he had taken a leading part, connected with the arrest of a notorious halfbreed, terrorizing the region roundabout, had brought him rather close to a fade-out since he met with serious wounds in the resulting scrimmage before he and his pal were able to overcome the desperado.
