"That's just it," exclaimed Barney disgustedly. "Steamboat and everything. You're not a real explorer unless some society backs you up with somebody's money to the tune of fifty thousand or so; till you've got together a group of scholars and seamen for the voyage. Then the proper thing to do is to get caught in the ice, you are all but lost. But—the ice clears at the crucial moment, you push on and on for two years; you live on seal meat and whale blubber. Half your seamen get scurvy and die; your dogs go mad; your Eskimos prove treacherous, you shoot one or more. You take long sled journeys, you freeze, you starve, you erect cairns at your farthest point north, or west, or whatever it is. Then, if you're lucky, you lose your ship in an ice-jam and walk home, ragged and emaciated. A man that does it that way gets publicity; writes a book, gets to be somebody.

"You see," he went on, "we've sort of got in the way of thinking that it takes a big expedition to do exploring. But, after all, what good does a big expedition do? Peary didn't need one. He landed at the Pole with two Eskimos and a negro. Well, now it ought to be easy as nothing for two or three men in a plane, like that one of the Major's, to go to the Pole from here. There's a fort and trading post on Great Bear Lake with, maybe, a power-boat and gasoline. Then, if there happened to be a whaler, or something, to give you a second lift, why there you are!"

"Sounds pretty good," admitted Bruce. "But nobody would ever attempt it."

"Of course not," retorted Barney. "It's too simple."

The two following days the boys found themselves taking morning and evening walks down the track to the airplane, which still lay piled in sections by the track. They were surprised to see that no effort was being made to assemble it. The reason for the delay was made clear to them by an unexpected encounter on the evening of the second day.

Finding the Major pacing up and down before the machine, his slight limp aggravated by his very evident irritation, they were about to pass as if they didn't know there was a plane within a hundred miles, when they were halted by the upraised hand of the Major.

Immediately both boys clicked heels and saluted. Then they felt foolish for saluting in "civies."

"I see you are military all right," smiled the Major. "But how much do you really know about airplanes?"

"Oh," said Barney, with exaggerated indifference, "Bruce, here, knows a little and I know a little, too. Between us we might be able to assemble your machine, if that's what you want." In spite of his heroic attempts at self-control, his voice betrayed his eagerness. Truth was, his fingers itched for pliers and wrenches.

"That's part of what I want, but not all," the Major said briskly. "I am not an aviator myself, and my man has failed me at the last moment; had a trifling smash which resulted in a dislocated thigh. Out of service for the season. I need an aviator and a good one. He says there's only one other not attached to military units that he could recommend—a Canadian. But the plague of it is, the man can't be located."
