Chas. D. Walcott, Director of U. S. Geological Survey: "I am impressed with the admirable plan of the work and with the thorough manner in which geological principles and processes and their results have been presented. The text is written in an entertaining style and is supplemented by admirable illustrations, so that the student cannot fail to obtain a clear idea of nature and the work of geological agencies, of the present status of the science, and of the spirit which actuates the working geologist."
T. A. Jaggar, Jr., Harvard University: "An excellent statement of modern American geology, with abundant new illustrative material based upon the most recent work of government and other surveys."
Henry S. Williams, Yale University: "It is the best treatise on this part of the subject which we have seen in America."
R. S. Woodward, Columbia University: "It is admirable for its science, admirable for its literary perfection, and admirable for its unequalled illustrations."
