This report embodies a portion of the work which I have done in connection with the general study of the Atlantic coast line. Although part of a much more extended inquiry, it seems well to publish the results contained in this memoir in advance of my general report for the reason that the region constitutes a distinctly bounded field and also because the problems considered in this report have an important bearing on work which is in the bands of other divisions of the Survey.</p>Latitudes and Longitudes of Certain Points in Missouri, Kansas, and New Mexico2018-03-04T09:52:47-06:00https://digital.library.unt.edu/ark:/67531/metadc1115013/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1115013/"><img alt="Latitudes and Longitudes of Certain Points in Missouri, Kansas, and New Mexico" title="Latitudes and Longitudes of Certain Points in Missouri, Kansas, and New Mexico" src="https://digital.library.unt.edu/ark:/67531/metadc1115013/small/"/></a></p><p>A report about the latitudes and longitudes which were determined by the telegraphic method with respect to the observatory of Washington University.</p>On Invertebrate Fossils from the Pacific Coast2018-03-04T09:52:47-06:00https://digital.library.unt.edu/ark:/67531/metadc1114968/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1114968/"><img alt="On Invertebrate Fossils from the Pacific Coast" title="On Invertebrate Fossils from the Pacific Coast" src="https://digital.library.unt.edu/ark:/67531/metadc1114968/small/"/></a></p><p>A report about fossils from the Chico-Téjon series of California.

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.</p>Earthquakes in California in 18922018-03-04T09:52:47-06:00https://digital.library.unt.edu/ark:/67531/metadc1115010/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1115010/"><img alt="Earthquakes in California in 1892" title="Earthquakes in California in 1892" src="https://digital.library.unt.edu/ark:/67531/metadc1115010/small/"/></a></p><p>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.</p>The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena2017-09-17T18:24:22-05:00https://digital.library.unt.edu/ark:/67531/metadc957836/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc957836/"><img alt="The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena" title="The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena" src="https://digital.library.unt.edu/ark:/67531/metadc957836/small/"/></a></p><p>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.</p>A Geological Reconnoissance in Central Washington2017-09-17T18:24:22-05:00https://digital.library.unt.edu/ark:/67531/metadc957843/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc957843/"><img alt="A Geological Reconnoissance in Central Washington" title="A Geological Reconnoissance in Central Washington" src="https://digital.library.unt.edu/ark:/67531/metadc957843/small/"/></a></p><p>From introduction: An examination of the country described in this paper was ordered by the Director of the U.

This compilation has been found extremely useful in the office, and it is believed that its usefulness will be greatly extended by placing it before the public. This list comprises between 9,000 and 10,000 positions. To publish it in extenso, with descriptions of the stations, their latitudes and longitudes, the distances and azimuths to neighboring stations, and the methods of determination, would extend this bulletin beyond all reasonable limits. To avoid making too bulky a volume, it has been decided to publish merely the latitudes and longitudes, with abbreviations indicating the authority, and references to the publications in which other data relating to the positions may be found.</p>A Mineralogical Lexicon of Franklin, Hampshire, and Hampden Counties Massachusetts2018-03-04T09:52:47-06:00https://digital.library.unt.edu/ark:/67531/metadc1115047/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1115047/"><img alt="A Mineralogical Lexicon of Franklin, Hampshire, and Hampden Counties Massachusetts" title="A Mineralogical Lexicon of Franklin, Hampshire, and Hampden Counties Massachusetts" src="https://digital.library.unt.edu/ark:/67531/metadc1115047/small/"/></a></p><p>This report provides a brief history of each mineral species occurring within the area of the three river counties in Massachusetts.</p>Report of Progress of the Division of Hydrography for the Calendar Year 18952018-03-04T09:52:47-06:00https://digital.library.unt.edu/ark:/67531/metadc1114945/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1114945/"><img alt="Report of Progress of the Division of Hydrography for the Calendar Year 1895" title="Report of Progress of the Division of Hydrography for the Calendar Year 1895" src="https://digital.library.unt.edu/ark:/67531/metadc1114945/small/"/></a></p><p>A report which provides the results of operations of the Division of Hydrography for the calendar year 1895.
