From preface: The following review of one of the Upper Cretaceous faunas as developed in the interior region of the United States has grown out of the study of a collection of fossils found by me in Huerfano park and adjacent localities in southern Colorado. This collection, the greater part of which was obtained during the summer of 1890, proved to be especially interesting because it afforded data for the closer correlation of certain Cretaceous strata in Utah with those east of the mountains, besides adding a considerable number of new species to the fauna of the Colorado formation. Dr. C. A. White, under whose direction the field work was done, generously assigned these fossils to me for study with a view to publishing the results, and I am greatly indebted to his sympathetic aid in every phase of the work.

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 preface: The preparation of this paper is due to the fact that the eruptive rocks occurring on Pigeon point, Minnesota, may be taken as types of similar eruptives found so widely spread over the Huronian and Keweenawan areas surrounding Lake Superior, and to the peculiar nature of the alteration these have superinduced in the fragmental rocks through which they have broken.

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 introduction: In presenting this paper the writer has two objects in view. The first is to add to the general knowledge respecting the geology of this central district [Appalachian coal basin]. The groups determined in this region will be carried over the adjoining territory if they can be distinguished and they afford a type-section of the Coal-measures where they are probably best developed. The results are not put forth as final, but as representing the most probable conclusions from the observed facts.

From outline: The present paper gives a detailed account of the glaciation of the Snowy mountains and of the upper valleys of the Yellowstone, whose deposits show an unusual phase of alpine glaciation. The evidence thus far gathered shows that a large body of ice, originating in the ice sheets of the Yellowstone National Park, pushed northward, filling the upper valleys of the Yellowstone and extending down that stream 36 miles north of the park boundary.

Preface: In the following bulletin I have brought together the more important results of experiments in high temperatures, made since the publication of my bulletin on the thermoelectric measurement of high temperatures.' Chapter I, in addition to pointing out certain inherent relations between metallic vapor tensions, has a direct bearing on pyrometry. Chapters 11 and ii are of geological importance, and the work was done for Mr. Clarence King. Chapter ii shows that in case of the igneous fusion of basic magma, the passage from liquid to solid is one of contraction, and measures the difference of specific volumes at the solidifying temperature. Chapter iii contains a full account of the thermal capacity of the same rock under the same conditions, and by aid of Chapter it leads to a numerical value for the relation of melting point to pressure, for silicates.

From introduction: The Three Forks sheet of Montana includes the area lying between the parallels of 450 and 460, and extending from longitude 111 to 1120. The three forks of the Missouri river unite in the north central portion of this area about 5 miles south of the northern line of the map.
