Excerpt from A Catalogue of Canadian Birds: With Notes on the Distribution of the Species Lest the reader might think that my idea of the extent and import ance of the work yet required is exaggerated, I will quote some extracts bearing on this subject from letters of prominent Naturalists who have made a special study of American birds. These letters were addressed to me privately, and were not written for publication, but as the matter is exceedingly instructive, coming from such eminent authorities, I have asked permission to print it.
