ORDERS. 



Lieutenant Alden and Mr. Sandford, with a boat and her crew, 

 will be prepared to join the Flying-Fish for duty, on the ship's 

 anchoring. 



Charles Wilkes, 



Commanding Exploring Expedition. 

 U. S. Ship Vincennes, 



At Sea, June 29th, 1840. 



U. S. Ship Vincennes, 



Savu-savu Bay, July 4th, 1840. 



Sir, 



You will proceed with the Flying-Fish to Nandi Bay, where you 

 will find the launch and first cutter. You will there receive Carter, 

 the pilot, on board, and proceed to Passage Island, from which point 

 you will steer so as to strike the reefs seen by you from the Annan 

 Islands. 



The theodolite Mr. Perry has, will be delivered to you. You will 

 land, if possible, on the above reefs, and observe a full round of angles, 

 together with the latitude and longitude, by equal altitudes. 



Any reefs you may meet with on your way, you will take sufficient 

 angles to establish their positions. The direction of the current will 

 also claim your attention, and the time of high and low water. 



Should you require the services of another officer, you will take one 

 from the launch or cutter. 



You will be expected to join me at Sandalwood Bay, on or before 

 the 10th instant. I am, &c, 



Charles Wilkes, 

 Commanding Exploring Expedition. 



Lieutenant James Alden, 



U. S. Ship Vincennes.

Savu-savu, July 3d, 1840. 



Sir, 



You will, with the launch and first cutter, Mr. Knox, proceed this 

 night to the harbour of Kombelau, which you will finish your survey
