U. 8. Ship Vincennes, 
Ovolau, May 13th, 1840, 
Sir,— 
You will proceed with the Flying-Fish to survey the following 
islands of the Feejee Group. For this purpose Lieutenant Underwood 
is ordered to accompany you, with a boat and crew, and Tom the 
pilot. 
1. Ambatiki, and its distance from Ovolau by patent log, examining 
its reefs on both sides. 
2. Nairai, with its reefs to the south. 
3. Angau. 
4. Matuku, Moalo, and Totoia. 
5. Reef called Tova. 
6. Vanua-vatu. 
7. An island upon the charts to the southward of Vanua-vatu, that 
I do not believe exists. 
8. Goro, Direction Island, and the Horseshoe Reef. 
Ten days are allowed you to complete this work. You will ascer- 
tain their bearings and distances asunder, latitude and longitude, and 
examine them for harbours; none is supposed to exist but at Moalo. 
You will not suffer any of your boats to be taken by surprise, or to 
land, unless you deem it necessary for the purpose of carrying on your 
surveying operations more effectually. I need not point out to you 
the observations required to be made. You will bring up your work 
every evening, and construct a chart as you proceed, on a large scale, 
a quarter of an inch to a mile. 
I enclose a chart herewith, on which the islands to be surveyed are 
marked. 
Should you not be able to finish all the surveys in the given time, 
you will omit Goro, Direction Island, and the Horseshoe Reef. 
Sketches of the islands are required, particularly those as they 
appear on approaching them from the sea; and as much of their topo- 
graphy as can be obtained in surveying them. 
Two more chronometers are furnished you, with their rate and 
errors. Do not omit daily comparisons as usual. 
Try your patent log well before using it: a strong line of twenty- 
five or thirty fathoms will be enough. 
Wishing you a successful cruise, | am, &c., 
Cuarites WItxkEs, 
LrEUTENANT OvERTON Carr, Commanding Exploring Expedition. 
U.S. Ship Vincennes.
