Read the excerpt from "Husky—The Wolf-Dog Of The North." In the annals of the country may be found the history of one dog-driver who wagered a thousand dollars that his favorite husky could start a thousand pounds on a level trail. Now the steel runners of a stationary sled will quickly freeze to the surface, and by the terms of the bet he was even denied the privilege of breaking the runners loose. But it was stipulated that the dog was to have three trials. The whole camp staked its dust upon one side or the other of the issue, and on the day of the trial turned out en masse. The dog was hitched to the loaded sled, and everything made ready. “Gee!” the master commanded from a distance. The dog swung obediently to the right, shrewdly throwing his whole weight upon the traces. “Haw!” The manoeuvre was duplicated to the left and the sled broken out. And then, “Mush on!” (the vernacular for “get up!”). The dog whined softly, driving his claws into the frozen trail, calling every muscle into play, digging away like mad. And in answer to this tremendous exertion, the sled slowly got into motion and was dragged several lengths. Let a man try the like and marvel. Of course it was an exceptional dog, but creatures are often measured by their extremes. Which piece of information should be included in a summary of this excerpt?
