"Well, they are intended to hold the 'gee-pole' in place. Do you know what a gee-pole is?"

The boys had never heard of the contrivance in question.

"It is a pole," explained their uncle, "about seven feet long, which extends forward from the right side of the sled, and serves as an aid in guiding. If you should try to guide your sled with the drag-rope alone, you would find that it would swerve on every uneven spot, and slip sideways on a slope, and dig its nose into the sides of the trail where the snow is soft; but with your right hand on a firm-set gee-pole, you will be able to steady your sled and guide it accurately where the trail is rough or rutty. The sled will answer to the lightest touch on the gee-pole. You can cut four of the poles in that thicket on the hillside yonder, and fit them into the rings. I believe Long Peter has already supplied himself with one."

Roly and David, after several minutes' search, found four straight saplings of the required length and thickness, and cut them down with their hatchets. The large ends they trimmed to the right size, and inserted them through the rings of the sleds, making them firm by driving chips wedgewise between the iron and the wood.

At eight o'clock all was ready, and the procession started with Long Peter in the lead. Behind them lay the mud flats, with the shining water in the distance. Before them to the northward stretched a broad and level expanse of snow, with here and there a patch of ice swept clean by the wind. The snow was almost as hard as the ice, and afforded a good running surface for the sleds. On either side of this broad valley of the Chilkat rose high, wooded hills, and behind them glittering peaks from which the snow would not entirely disappear even in midsummer, so Long Peter informed them.

For this kind of travelling the spiked "creepers" were a necessity, enabling the feet to obtain a firm hold on the alternate lanes of ice and icy snow. They were worn beneath the rubber shoe-packs, and fastened to the feet by leathern thongs.

They had not proceeded far, when they came to a low ridge or bank, so steep that Uncle Will was obliged to go to the assistance of the Indian. When the first load had been forced up the incline, the Indian returned with Uncle Will, and the two pushed up the second sled. Mr. Bradford and David followed with the third, the former pulling on the drag-rope, and his son pushing on the rear of the load. David was able to draw his own light load up the slope without assistance, and Roly came close behind him.

Unfortunately for Roly, he did not attack the ridge directly but diagonally, which brought one sled-runner higher than the other. In an instant over went the sled upon its side.

"What's the matter, Roly?" shouted Uncle Will, who had been watching from the other side of the bank.
