In the preparation of the bibliographical references, the object has been to include only those works that have a direct and vital bearing on the subject. A complete bibliography in each case would obviously be neither possible nor desirable. Nor, except in special cases, has any attempt been made to include articles or papers in periodicals or in the publications of learned societies. It will be sufficient to make a general reference here to some of the more important sources of information on the many topics covered in this volume. First among these sources probably should rank the publications of the Royal Society of Canada. The Society has published in a separate volume a very full General Index to its _Proceedings and Transactions_, 1882-1906, compiled by Dr. Benjamin Sulte. For volumes subsequent to 1906, the individual indexes should be consulted. A key to the Annual Reports of the Geological Survey of Canada is found in two General Indexes, one covering the years 1863-1884, and the other the years 1885-1906. The latter, compiled by F. J. Nicolas, is very complete. Wurtële's Index to the _Transactions_ and other Publications of the Literary and Historical Society of Quebec, 1829-1891, furnishes a guide to the material issued by this oldest of Canadian learned societies. Unfortunately, no general index is available for the publications of the Canadian Institute, which cover a very wide and important field; nor for those of the Historical and Scientific Society of Manitoba, the Ontario Historical Society, the Nova Scotia Historical Society, and various other Canadian institutions of a similar character. Much important material, bearing on, or supplementary to, the topics treated in the several volumes of the _Makers of Canada_ will be found in the foregoing publications. The reader may also find it profitable in many cases to consult the publications of the American Historical Association, and the State Historical Societies of New York, Maine, Michigan, Wisconsin, and Minnesota. A great deal of important material is also to be found in Canadian and other periodicals. Of the more significant of these, the _Revue Canadienne_ marked the completion of its fifty-third volume in 1907 by publishing in separate form a comprehensive Index to the entire series up to that year. In consulting other Canadian magazines, reference must in most cases be made to the individual indexes in each volume. The series of the _Canadian Monthly_ and the _New Dominion Monthly_ are, however, fully covered by Poole's _Index_; the _Canadian Magazine_, to a large extent, by Wilson's _Guide to Periodical Literature_, as well as by a General Index published by the magazine in 1907. A key to the publications of several Canadian historical societies and periodicals, since the year 1906, is furnished by the _Magazine Subject-Index_ (Boston). The three admirable American guides mentioned above, that is, Poole's _Index_, Wilson's _Guide_, and the _Magazine
