THE WORK OF THE COAST AND OEODETIC 

 SURVEY.* 



It is a high privilege to address j'ou to- 

 day on the work of the oldest bm-eau of 

 applied science under the government, a 

 bureaii which invokes the aid of science in 

 its intensely practical* work, where theory 

 and practice go hand in hand. It seems 

 reasonable to hope that some inspiration 

 may be drawn from an account of its work, 

 by young men who are about to take up 

 the pleasures and burdens of a share in 

 the world's work after going forth from 

 an educational institution which announces 

 as the underlying principle which controls 

 its method, the advance of the practical, 

 side by side with the scientific. It is par- 

 ticularly pleasant to speak of the survey 

 in a locality where such familiar names as 

 Lovering, Bowditch and Pierce will be 

 recognized as among those who helped it in 

 its earlier struggles for recognition, and 

 that of a statesman like Charles Sumner 

 as one of its staunch supporters, those of 

 Louis and Alexander Aga.ssiz, who utilized 

 the opportunities afforded by the survey to 

 further the aims of science and to add 

 luster to the fame of its work by their asso- 

 ciation with it, and where it will be remem- 

 bered that if Jlassachusetts gave a Peirce 

 to the survey, the survej^ gave a Menden- 

 hall and a Pritchett to lla.ssachusetts.
