A report which provides information about the analysis of rocks, minerals, ores, waters, sediments, coals, metals, and many more.

This report was prepared with 29 specimens of rock which are described in this report.

This report provides a brief history of each mineral species occurring within the area of the three river counties in Massachusetts.

A bibliography which includes geologic publications printed in North America and geologic publications about North America for the year 1890.

A report which presents a record of publications on North American geology, paleontology, petrology, and mineralogy for the year 1895.

A bibliography of geologic literature published in North America, and such literature on North America wherever published. It contains publications from 1732 to those received prior to the close of 1891.

A bibliography which records papers pertaining to North American geology, paleontology, petrology, and mineralogy published in the year 1894.

Introduction: It seems important that several general facts should be stated for the full understanding of terms used and allusions made in this report. The field considered is the region lying between the Missouri and James rivers, and between the latitudes of Jamestown, N. Dak., and Huron, S. Dak. 1. As has been stated in papers published by Chamberlin, Upham, myself, and others, several more or less distinct moraines have been observed in the Mississippi Valley. It has been found convenient to distinguish the outermost three by special names. President Chamberlin has named them, beginning with the outermost, Altamont, Gary, and Antelope moraines, from localities south of Big Stone Lake, and these names have been quite generally adopted. Upham and others have named them the First, Second, and Third, and as the outermost two are the more prominent, they have also been called the Outer and Inner moraines. Each of these, especially the First and Second, has subordinate divisions, which mark the borders of the different lobes into which the margin of the ice sheet was often divided. 2.) It is assumed that the reader is familiar with the generally recognized features of drift formations, such as the undulating topography …

A report about recorded shock waves observed or felt on Mount Hamilton, and all those reported to the Lick Observatory by letter, as well as newspaper reports of such earthquakes that occurred in California during that year.

From outline: The aim of this paper is to review the progress of our knowledge concerning a well defined system of rocks on'the Atlantic border, named the Newark system; to summarize the present state of information concerning it, and to discuss the bearing that its study has on principles of correlation.

A report about waters of the Coastal Plain region of the Atlantic Slope. Most of the waterways are of bad quality in the Coastal Plain. It discusses the hygiene of various waterways of the region.

A paper about the geography, topography, and stratigraphy in Wyoming.

A report about silicates which form nine-tenths of the earth's crust and are therefore of fundamental importance to geological changes. The report discusses analyzing them by finding out where they came from and what they are comprised of.

The following report contains all of the shocks observed or felt on Mount Hamilton in 1892, and all those reported to the Lick Observatory by letter, as well as newspaper reports of earthquakes.

From introduction: This report deals with the Middle and Upper Carboniferous System.

A report about the Fort Riley Military Reservation's geology in Kansas.

A paper pertaining to the trap dikes of the region around Lake Champlain.

From letter of transmittal: SIR: I beg to transmit herewith, for publication as a bulletin, a gazetteer of Kansas.

This bibliography is a record of North American paleontology for the years 1888 to 1892. It is a condensed review of the paleontologic literature appearing during the period.

From introduction: In December, 1892, as the result of field work on the part of Dr. G. H. Williams in the northern and of the writer in the southern portion of South Mountain, there appeared a preliminary description of two of the rock types, in which their identification as ancient volcanics was announced. In this bulletin it is proposed to substantiate that identification with more detailed proof. It is further proposed to show that these ancient igneous rocks were, at the time of their consolidation, identical in character with their recent volcanic analogues, and that their present differences are due to subsequent changes, chief among which has been devitrification. It is also proposed to recognize these facts in the nomenclature.

From outline: This paper, after discussing general principles connected with the study and description of the Tertiary or Cenozoic rocks and fossils contained in them, takes up the Neocene deposits of the United States in particular. A chapter is devoted to a summary of what is known in regard to the Neocene of the eastern coast of the United States, each State in geographical order being separately considered, beginning at the north.

From introduction: An examination of the country described in this paper was ordered by the Director of the U. S. Geological Survey at the request of persons interested in the development of the state of Washington, for the purpose of ascertaining how far the geological structure of the arid portion of the state favored the hope of obtaining artesian water for irrigation.

From outline: The primary object of this bulletin is the presentation of a summary of our present knowledge of the North American Cretaceons and a discussion of the system as it is developed on this continent, discussion of or direct reference to the details of the system as it is developed in other parts of the world being omitted.
