Tables of geographic positions, azimuths, and distances, together with lists of barometric altituudes, magnetic declinations, and itineraries of important routes, from data gathered by parties of the United States Geographical Surveys west of the 100th meridian, operating in the States and Territories of California, Colorado, Nebraska, Nevada, Oregon, Arizona, Idaho, Montana, New Mexico, and Wyoming, 1883
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. The speed with which results were demanded and produced during the years that field observations were in progress, and the subsequent paucity in office assistance, have rendered it impossible to exhaust the subject under any one of the headings found in the contents. Such results, however, as would seem to be of the greatest general interest and usefulness have been collected in this volume, which is submitted to take a place among the miscellaneous publications of the Survey, wherein its importance will correspond in a measure to the number of positions, elevations, distances, &c. (of which there are many), not hitherto in print.
