The number of soundings taken during the year was 701, almost all 

 of which were located with sufficient accuracy to be of hydrographic 

 value ; of these, 10 i were also dredging stations. 



During the winter and spring the vessel was employed in hydro- 

 graphic work for the Navy Department ; searching for reported dangers 

 in the West Indies and between there and the Chesapeake; running lines 

 of soundings across the Caribbean Sea and among some of the islands ; 

 taking serial temperatures and noting surface currents ; making an ex- 

 amination of a part of Savanijla Bay, United States of Colombia, and 

 establishing the longitude of Cai^e San Antonio light-house, Cuba. 



Following is a list of reported dangers over or near which the depths 

 were found in the positions given :
