This story, which is an account of the peculiar and marvelous adventures by which two Canadian boys--Norman Grant and Roy Moulton--achieved a sudden fame in the Arctic wilderness of the great Northwest, had its beginning in the thriving city of Calgary. The exact time was the big day of the celebrated "Stampede," Calgary's famous civic celebration. It was in July and among the many events that had drawn thousands of people to the new Northwestern metropolis, Norman and Roy were on the program as aviators and exhibitors of their new aeroplane.
