work of estab- During this year the work of determining longitudes by 

 tude S s b°y n teie- telegraph was continued by the party under Lieutenant 

 grap , con m- Q ommanc [ er Green, in the Gettysburg, and successfully com- 

 pleted. In addition to the places before established the 

 longitudes of the following ports were determined : King- 

 ston (Jamaica) ; San Juan de Puerto Bico; St. Thomas ; 

 St. Croix; St. John (Antigua); St. Pierre (Martinique); 

 Bridgetown (Barbadoes); Port Spain (Trinidad). 



The idea of employing the electric telegraph in determin- 

 ing differences of longitudes is eminently an American one, 

 and proved its superiority over every other method by 

 the accuracy of its results. 



On the return to the United States, after completing 

 her work in the West Indies, the Gettysburg ran a line of 

 Soundin-s t.x- soundings from Saint Thomas, via Bermuda, to the Capes 

 wXf* Get "of the Chesapeake.
