- From preface: The present publication is the first contribution to a research on the physical constants of rocks; the experiments of which are to follow a general plan devised by Mr. Clarence King, former Director of the U. S. Geological Survey.
- Types of the Laramie Flora
- From explanatory remarks: I have in preparation a work on the flora of the Laramie group, in which will be described and figured a very large number of fossil plants, most of 'which were collected by myself in the seasons of 1881 and 1883 and the elaboration of which has occupied most of my time since the latter date.
- The Geology of Nantucket
- Letter of transmittal: I have the honor to transmit herewith a report on the geology of the island of Nantucket. 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.
