tide-staves, which observations will be continued by you after that 

 officer leaves. I am yours, very respectfully,

Captain Wm. L. Hudson, 



Peacock. 



U. S. Ship Vincennes, 



Hai-bour of Pago-pago. 



Sir, 



You will receive on board Lieutenant Perry, and Mr. Colvoco- 

 ressis, of the Peacock, with their boats and crews, delivering your 

 boats to the Peacock, and then you will carry into effect the following 

 instructions. 



Proceed to the eastern point of the island of Upolu, then commence 

 the survey of its south side, particularly examining it for harbours, 

 and all places that may afford any shelter for vessels ; the boats are 

 intended to operate with you, and will trace the shore or reefs by 

 compass, and astronomical bearings. You will be very particular in 

 keeping your deck-board as ordered for surveying duty. The boats 

 will make sketches of all the shores, and you will be particular in 

 getting your observations for latitude and longitude, at the same time 

 taking astronomical bearings, that the point may be determined there- 

 from. If possible, you will pass between Upolu Island and Manono, 

 making your survey embrace the eastern shore of Manono Island ; 

 but if the passage proves dangerous, you will then go round Manono, 

 between it and Apolima, and survey the whole of Manono Island 

 only. You will then proceed to the eastward, along the northern 

 shore of Upolu, to the harbour of Apia, continuing the survey in 

 like manner up to that harbour ; here you will again rejoin the Pea- 

 cock, — when Lieutenant Perry and Mr. Colvocoressis will rejoin the 

 Peacock, and you receive your boats, and remain under the orders of 

 Captain Hudson until further instructions. During the survey, you 

 will ascertain how far soundings exist from the shore. You will 

 proceed to sea at daylight. 



I am, very respectfully, 



Your obedient servant, 

 (Signed) Charles Wilkes, 



Commanding Exploring Expedition. 



Lieut. Com. R. F. Pinkney, 



Schooner Fiving-Fish.
