In the summer-time, when the snow and ice are gone and man travels by canoe and poling-boat, the huskies are thrown upon their own resources. They do not work; wherefore should they be fed? Hence they become splendid scavengers and perform prodigies of benevolence in the matter of sanitation. Nothing escapes them. Not a bone but is cracked for its marrow; not a tin can but shines clean and bright on the inside. They are also excellent fishers, and during the salmon-run no dog goes hungry. —“Husky—The Wolf-Dog of the North,”
Jack London
