THE CELEBRATION OF THE ONE HUNDREDTH ANNIVER- 

 SARY OF THE ORGANIZATION OF THE U. S. 

 COAST AND GEODETIC SURVEY 



In 1816 the U. S. Coast Survey was organized under Mr. Ferdinand 

 Rudolph Hassler as Superintendent and field work was begun. This 

 event was fittingly celebrated in Washington on the 5th and 6th of 

 April last by meetings to which the public was invited in the auditorium 

 of the New National Museum. At these meetings papers were pre- 

 sented by representative men in the fields of Science, Engineering, Com- 

 merce, the Federal Government, and Military Affairs. The celebra- 

 tion closed with a banquet at the New Willard hotel on the evening 

 of the sixth, at which the President of the United States was the princi- 

 pal speaker. The present Superintendent of the Coast and Geodetic 

 Survey, Mr. E. Lester Jones, presided at the banquet and at the three 

 public sessions at the Museum. Abstracts of the addresses delivered 

 at the Museum and at the banquet are given below. 



AFTERNOON OF APRIL 5TH 



Dr. Hugh M. Smith, Commissioner of Fisheries: The Bureau of Fish- 

 eries and its relation to the United States Coast and Geodetic Survey. Dr. 

 Smith said that early in the history of the Bureau of Fisheries there 

 began close cooperative relations with the Coast and Geodetic Survey. 

 The former has always depended upon the latter for its basic triangula- 

 tion whenever a biological survey of any kind has been undertaken in 

 a region in which the Coast and Geodetic Survey has operated, which 

 of course means anywhere on the coast of the United States. On the 

 other hand, the hydrographic and topographic results of this biological 

 work have always been made available to the Survey. On both the 

 Atlantic and the Pacific coasts a considerable part of the offshore sound- 

 ings found on the charts was made by the steamers Fish Hawk and 

 Albatross in pursuance of their fishery investigations, and some of the 

 inshore data of certain of the earlier charts came from reconnaissances 

 by the Albatross. While much of the latter has been superseded by 

 more accurate work, as the Coast Survey was able to extend its oper- 

 ations, it served a good purpose for some years. 



Dr. L. A. Bauer, Director of the Department of Terrestrial Magne- 

 tism, Carnegie Institution of Washington : The work done by the United 

 States Coast and Geodetic Survey in the field of terrestrial magnetism. 

 From the earliest days of the Coast Survey magnetic observations have 

 been considered a legitimate and useful part of its work, but it was not
