The author has endeavored to reach these truths and to show this harmony by the aid, primarily, of mechanical science and the analogies which it affords.

operations of the survey have been extended over the eastern part of the United States, under the authority of a provision in the appropriation act of 1882-'83, requiring it to make a geological map of the United States. The general map is to be made on a scale of $1/250000$, or four miles to the square inch. Besides the general report of the progress of the work of the survey and the administrative reports of the heads of divisions (embracing geologic, paleontologic, and chemic work), the present volume contains papers on "Hawaiian Volcanoes," by Clarence Edward Button; "The Mining Geology of the Eureka District, Nevada," by J. S. Curtis; "Popular Fallacies regarding the Precious Metal Ore Deposits," by Albert Williams, Jr.; "The Fossil Ostreidæ of North America," by Dr. Charles A.

While it bears the same title, with the exception of the date, as the former volume which covered the calendar year 1882, it is not a reprint, or second edition of that report. The tables of production are re-given; but it has been the endeavor to avoid as far as possible a reproduction of the descriptive matter. While some of the main topics discussed in the former volume, concerning which nothing new has been brought out, are omitted, other subjects, which were not adequately discussed before, are now dealt with at considerable length. A considerable number of the articles appear as special contributions, with the authors' names attached.
