PREFACE 
Tus work has been prepared by the Canadian 
Institute for the members of the Twelfth Geo- 
logical Congress and for all who may have an interest 
in the history and natural history of the city and 
vicinity. The articles have been generously contri- 
buted by specialists in their respective fields, and 
represent more than mere compilations. The maps 
and illustrations have either been prepared for this 
book or are reproduced here from original sources by 
permission. Credit is given in connection with each. 
To the contributors, the publishers, and to the many 
friends who have so freely aided with information or 
advice, the members of the publication committee 
desire to express their sincere indebtedness, 
J. B. Tyrretz, President. 
J. H. Favrz, Editor.
