APPENDIX. 375 
United States' Ship Vincennes, 
Hampton Roads, August 18th, 1838. 
Sir, 
I have this morning ascertained that only one set of pump-gear is 
on board this vessel, and one on board the Peacock, which are now 
in use. 
The pumps of the Vincennes are 6| inches. 
2 " Peacock " 6 « 
2 « « « 61 " 
We are now otherwise ready for sea, but cannot sail without these, 
as they cannot be obtained elsewhere ; also two kedges are required, 
and a hose for the pumps, and pipe for the hose of the forcing-pump, 
and an iron brake for the Vincennes. 
I have to request the favour of you to direct that three complete 
sets of pump-boxes, &c, for each vessel, may be furnished to-day. 
All these articles have been repeatedly called for by the officers 
from this ship, but without success. 
I am, most respectfully, Sir, 
Your most obedient servant, 
Charles Wilkes, 
Commanding Exploring Expedition. 
Commodore L. Warrington, 
Navy Yard, Gosport, Va.

Sir, 
You will proceed with all practicable despatch to Port Praya, in 
the island of St. Jago, where you will remain five days, and then 
proceed to Rio de Janeiro, where you will await further orders. 
During your stay at Port Praya, you will fill up with water, and 
supply your crew fully with fresh provisions and vegetables. 
You will leave a communication with the consul of that port on 
your departure, addressed to me, in case you should not hear from 
me before that period. 
I am, &c, 
Charles Wilkes, 
Commanding Exploring Expedition. 
To Lieut. Com. A. K. Long, 
U. S. Ship Relief.
