At the Rainbow's End by Jack London — Read

With Circle City in prospect and the last ice crumbling under his runners, Montana Kid took advantage of the lengthening days and travelled his dogs late and early. Further, he had but little doubt that the owner of the dogs in question had taken his trail, and he wished to make American territory before the river broke. But by the afternoon of the third day it became evident that he had lost in his race with spring. The Yukon was growling and straining at its fetters. Long detours became necessary, for the trail had begun to fall through into the swift current beneath, while the ice, in constant unrest, was thundering apart in great gaping fissures. Through these and through countless airholes, the water began to sweep across the surface of the ice, and by the time he pulled into a woodchopper's cabin on the point of an island, the dogs were being rushed off their feet and were swimming more often than not. He was greeted sourly by the two residents, but he unharnessed and proceeded to cook up.

Donald and Davy were fair specimens of frontier inefficients. Canadian- born, city-bred Scots, in a foolish moment they had resigned their counting-house desks, drawn upon their savings, and gone Klondiking. And now they were feeling the rough edge of the country. Grubless, spiritless, with a lust for home in their hearts, they had been staked by the P. C. Company to cut wood for its steamers, with the promise at the end of a passage home. Disregarding the possibilities of the ice-run, they had fittingly demonstrated their inefficiency by their choice of the island on which they located. Montana Kid, though possessing little knowledge of the break-up of a great river, looked about him dubiously, and cast yearning glances at the distant bank where the towering bluffs promised immunity from all the ice of the Northland.
