You will proceed with the Flying-Fish, to beat up for the Horse- 
shoe Shoal, ascertain its correct latitude and longitude from Ovolau, 
and angling from it on the different islands in sight, and getting its 
extent. Thence to the island of Goro, which you will carefully exa- 
mine for harbours, and sounding carefully any that may be found; 
tracing its reefs and shores, and ascertaining the latitude and longitude 
of one of its points, by observations with the sextant and artificial 
horizon. 
After completing this duty, you will stand in for Savu-savu, and if 
I should not be there, you will proceed direct to Sandalwood Bay. 
It is expected that this duty will be quickly, at the same time 
effectually, performed. Mr. Colvocoressis, with a boat and her crew, 
will join you from his ship.
