Notes on the stratigraphy of California
A complete examination of the Coast Ranges of California can hardly be undertaken by the Geological Survey for some years to come, consistently with the plans at present formed. The detailed study of certain small areas in these ranges, however, raised a number of questions as to the age and stratigraphical relations of the various series of beds, which it seemed necessary to answer as well as ci

Observations on the junction between the Eastern sandstone and the Keweenaw series on Keweenaw Point, Lake Superior
Although the copper-bearing rocks of Lake Superior and the adjoining formations have attracted the attention of geologists for fifty years past, there are yet remaining unsolved very many problems with regard to them. We have ourselves, indeed, written at some length with regard to these rocks, and one of us has even attempted a general account of the series as a whole. In the course of our invest

On the higher Devonian faunas of Ontario county, New York
The materials and the conclusions presented in this paper are the partial results of studies of the Devonian of Western New York, which have been of several years duration. Since the summer of 1877 much attention has been given to the finer subdivision of the Devonian on strictly paleontological evidence, the rich development of Devonian faunas within Ontario County, and in its vicinity, having af

Sketch of paleobotany
To understand the true force of the facts of paleobotany as arguments for geology it is essential that their full biologic significance be grasped. It has therefore been deemed proper, in this introduction to the several tabular and systematic statements which will make up the bulk of the volume and bear chiefly upon the geological aspect of the subject, to consider certain of the more important b

Through the following tables there are presented, in accessible form, such portions of the more important numerical results of this Survey, from the year 1873 to 1879, inclusive, as it has been found neeessar, to compute pari passu with the plottings made from the field notes, together with such additional determinations as may have been required in the construction of the final atlas sheets.
