Handbook to the New Gold Fields 

Excerpt: "The problem of colonisation in the north-western portion of British America is fast working itself out. The same destiny which pushed forward Anglo-Saxon energy and intelligence into the rich plains of Mexico, and which has peopled Australia, is now turning the current of emigration to another of the "waste-places of the earth." The discovery of extensive goldfields in the extreme west of the territories now occupied by the Hudson’s Bay Company, is a great fact. It no longer comes to us as the report of interested adventurers, or the exaggeration of a few sanguine diggers, but with well-authenticated results-large quantities of gold received at San Francisco, and a consequent rush of all nations from the gold regions of California, as well as from the United States and Canada. The thirst for Gold is, as it always has been, the most attractive, the strongest, the most unappeasable of appetites-the impulse that builds up, or pulls down empires, and floods the wilderness with a sudden population."
