EXECUTIVE ORDER. 
As it is desirable that uniform usage in regard to geographic 
nomenclature and orthography obtain throughout the Executive 
Departments of the Government, and particularly upon the maps and 
charts issued by the various Departments and bureaus, I hereby con- 
stitute a Board on Geographic Names and designate the following 
persons, who have heretofore co-operated for a similar purpose under 
the authority of the several Departments, bureaus, and institutions 
with which they are connected, as members of said Board: 
Prof. Thomas C. Mendenhall, United States Coast and Geodetic 
Survey, chairman. 
Andrew H. Allen, Department of State. 
Capt. Henry L. Howison, Light-House Board, Treasury Depart- 
ment. 
Capt. Thomas Turtle, Engineer Corps, War Department. 
Lieut. Richardson Clover, Hydrographic Office, Navy Department. 
Pierson H. Bristow, Post-Office Department. 
Otis T. Mason, Smithsonian Institution. 
Herbert G. Ogden, United States Coast and Geodetic Survey. 
Henry Gannett, United States Geological Survey. 
Marcus Baker, United States Geological Survey. 
To this Board shall be referred all unsettled questions concerning 
geographic names which arise in the Departments, and the decisions 
of the Board are to be accepted by these Departments as the standard 
authority in such matters. 
Department officers are instructed to afford such assistance as may 
be proper to carry on the work of this Board. 
The members of this Board shall serve without additional compen- 
sation, and its organization shall entail no expense on the Government. 
BENJ. HARRISON.
