APPENDIX. 425 



proceed to the next island of this group, called Upolu, and enter the 

 harbour of Apia, situated on the northern side, and will remain while 

 the Flying-Fish and your boats are making a survey of it, by circum- 

 navigating it, and making all possible observations, sketches, &c. 



The officers sent in the schooner and boats will be careful to 

 examine and survey any harbour or shelter that may be found, 

 making sketches of their approach, and surveys ; also observations to 

 determine their situation, &c. 



You will also make a careful survey of the harbour of Apia. 



Every facility will be afforded to the scientific corps, for making 

 collections and observations on shore; all information possible will be 

 obtained from the missionaries and others, relative to the island ; as to 

 the population, productions, soil, number of white missionaries, &c. 



You will remain at Apia until you hear from me, or until you have 

 completed the duties required, which I deem five days amply sufficient 

 for. One of the officers of the Porpoise was left to superintend tide- 

 staves, which observations will be continued by you after that officer 

 leaves. 



I am yours, very respectfully, 



(Signed) Charles Wilkes, 



Commanding Exploring Expedition. 



Captain* Wm. L. Hudson, 



Peacock. 



U. S. Ship Vincennes, 



Harbour of Pago-pago. 

 Sir, — 



You will receive on board Lieutenant Perry, and Mr. Colvocoressis, 

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

 the Peacock, and then you will carry into effect the following instruc- 

 tions. 



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,
