The author has studied the widespread and complex glacial formations of Canada too long to be content to explain them all by one dominant cause, in the rough and ready method employed by so many of his juniors. He has long been convinced that we must take into vi PREFACE. account the agency both of land ice and sea-borne ice in many forms, along with repeated and complex elevations and depressions of large portions of the continent, in order to account for the effects observed. He is disposed,

He is disposed, however, to seek for the causes of changes of climate rather in geological and geographical agencies than in astronomical vicissitudes, some of which are too slow and uncertain in their operation, and others altogether conjectural. Such views are less sensational than those which invoke vast and portentous exaggerations of individual phenomena, but they are likely, in the end, to commend themselves to serious thinkers, especially when they are confirmed by the facts observed in the regions which are, of all others, best suited for the study both of extinct and recent ice-action.
