The Survey of the Coast. 75 



of its usefulness, and commerce is to continue to reap the legiti- 

 mate benefit of the expenditures already incurred. Fortunately 

 the survey has been conducted on such sound principles it meets 

 the increasing requirements for accuracy demanded by the navi- 

 gation of to-day, as fully as it did the more simple needs of the 

 navigator of forty years ago, and it is fairly believed, whatever 

 may be the necessities of the future, that it will still supply the 

 information desired. 



The Surveys are published in four hundred and fifty charts 

 designed to meet the various needs of the ISTavigator and Civil 

 Engineer, for either general or local purposes ; over thirty thou-

 increasing demand. 



The assistance rendered to the armies and fleets of the Union, 

 in the late Civil War, is a chapter in the history of the Survey

 beset with demands for information from all over the country, 

 for descriptions not of -the coast alone, but all sections of the 

 interior representing the seat of war. Fortunately the experts

 oflice in this cause resulted in the publication of a series of " War 

 Maps " of the interior, for which there is frequent demand even 

 at the present day. This was all additional work to a force 

 already overburdened in the preparation of manuscript maps and 

 special information, compiled from the reports of the Field par- 

 ties ; especially of those localities that had only recently been 

 surveyed. And in all the din and excitement of the call to arms, 

 with hosts of stalwart, honest men assembled around him, that 

 might give in their learning the wisdom of the world, the con- 

 trolling mind of the Survey, that had labored diligently and 

 sought knowledge patiently, was a chosen counsellor of the Chief 

 of the Nation. Declining military honors, the profession in 

 which he had been educated, he devoted himself with renewed 

 energy to assisting the nation's efforts in those special duties he 

 knew so well how to perform. A patriot himself of the purest 

 type, he inspired those around him by his ennobling spirit and 

 zeal in the cause. 



An average of twenty parties were maintained with the Army 

 and Navy during all the years of the war, rendering services of 

 acknowledged value to the military forces. An officer of the Coast
