Recent advances have made physical geography almost a new science. Professor Russell here presents a single phase, but one of great importance. The work is based upon his original investigations, and is at once thoroughly scientific in substance and enjoyably popular in style.

As a text-book or reading book for students in geography and geology the “Lakes of North America” possesses a unique value. Its interest to the general reader is enhanced by its illustrations and its happy descriptions of lake scenery.

Recent explorations have shown that North America contains thousands of glaciers, some of which are not only vastly larger than any in Europe, but belong to types of ice bodies not there represented. In the study of the glaciers of North America, and especially of those in Alaska, Professor Russell has taken an active part; and this book not only presents the results of his own explorations but also a condensed and accurate statement of the present status of glacial investigations. Its popular character and numerous illustrations will make it of interest to the general reader.
