At Sea, July 16th, 1839. 
With a view of avoiding any misapprehension in regard to the 
duties of the artists attached to the Exploring Expedition, and that 
their services and time may be as usefully engaged as possible, I 
deem it proper to state, that they will not confine themselves ex- 
clusively to any particular branch, without directions from me, but 
will divide their duties among the different departments in such a 
manner as may be deemed most conducive to the interest and benefit 
of the whole. 
Very respectfully, &c, 
Charles Wilkes, 
Commanding Exploring Expedition,
