in the belief that the benefits gained outweigh the unavoidable disadvan-
tages.

The Centenary History is a series to be written by individual authors; but
it is also planned to have a certain common character and to follow a com-
mon method. It has been agreed that a general narrative treatment was
necessary and that each author should deal in a balanced way with
economic, political, and social history. This varied and comprehensive
account will, it is hoped, be presented in a scholarly, interpretative, and
readable fashion, so that the student may be informed and the general
reader interested.

The editors welcome Tryggvi J. Oleson's volume, the second to be pub-
lished in the series. Professor Oleson's purpose is to examine low explorers,
settlers, and hunters from Norway, part of the great movement of the
Vikings in the eighth and ninth centuries, made their way across the north
Atlantic and formed contacts with the lands of the Canadian Arctic. These
contacts lasted centuries, were known in mediæval Europe, and affected
the lives of both the Greenlanders and the Arctic aborigines. This northern
route became one by which fishermen, traders, and explorers from England
made their way into the Canadian north. Professor Oleson has told a little-
known story, but one full of suggestion, of what perhaps is to be termed
the pre-history of Canada.
