Excerpt: ...standard datum for geodetic operations in Canada and Mexico, it became a matter of international importance, and consequently its designation was changed by the Survey in 1913 to that of the " North American datum." Plans are now under way for carrying the primary triangulation of the United States and Canada to the Yukon, and the prediction is here made that eventually the 50 miles which separate Alaska from Siberia will be spanned and a junction be effected with the great systems of Asia, Europe, and Africa. Then, with the extension from Mexico through Central and South America, the data will be available for a " world datum," and the final word will l1ave been said in the geodetic work of the earth. BASE-LINE MEASUREMENTS Closely related to, and forming an integral part of the triangulation executed by the Coast and Geodetic Survey, is the measurement of the base lines for controlling the lengths in triangulation. In this work the Survey has furnished much of interest and of value to the geodesist. Ever has it kept keenly before it the necessity for refined measurements, and many valuable devices to accomplish this desired result have been added by members of the force. BASE BARS The Duplex bars, invented by Assistant William Eimbeck and constructed by E. G. Fischer, are probably the best form of base bars ever devised, and gave a very high degree of precision; but they were soon replaced by the tape as a form of base apparatus. The only bar used in the United States, and probably in the world, which gives entire satisfaction, so far as accuracy is concerned, is the iced bar, designed by President R. S. Woodward, of the Carnegie Institution, when an assistant in the Survey. Owing to the great cost per kilometer...

Excerpt from Centennial Celebration of the United States Coast and Geodetic Survey, 1916 The commemoration of the one hundredth anniversary of the organization of the Coast Survey, celebrated in the city of Washington on April 5 and 6, 1916, is a memorial to the wise foresight of those early statesmen of our Republic who laid deep and well the foundations of a bureau which has done so much to establish the reputation of the country in the development of mathematical and physical science, and has made so ample a return for the support it has received from the Nation by safeguarding life and commerce on our coastal waters, and by making certain the means whereby are reproduced the public and private lines of proprietary subdivisions. The celebration of the centennial included three public sessions devoted to appropriate addresses, held in the New National Museum; a banquet held in the New Willard Hotel, at which the invited speakers were the President of the United States, the Minister of Switzerland, the Secretaries of the Navy and of Commerce, and Doctor T. C. Mendenhall, former Superintendent of the Coast and Geodetic Survey; and included also an exhibit. The Superintendent presided at each of the three sessions and served as toast master at the banquet. The exhibit, held in the New National Museum, was a comprehensive display of the various types of instruments used in the operations of the Survey, ranging from historic examples of apparatus designed and used by Hassler and Bache to the latest forms employed at the present day. Notable features were astronomical, geodetic, tidal, topographic, and hydrographic apparatus which owe their origin to the Survey and were constructed in its workshops. The manifold experiences of the field parties of the Bureau under the various conditions encountered in the field of operations, extending from the Arctic Ocean to the southern limits of the Philippine Archipelago, were illustrated by prints from photographs made in the field. The progress of the developments that has marked the improvements in surveying results between 1816 and 1916 was graphically shown by comparison of field sheets and by published charts from various periods. The addresses delivered and herewith reproduced represent the judgment of representative leaders in the scientific, engineering, civic, and military life of the country upon the value of the operations and results of the first century of the Surveys existence. They contain inspiring forecasts of the results to be expected from its maintenance and development in accordance with the ever-increasing demands upon it incidental to the growth of the Nation and the ceaseless activities of nature.
