APPENDIX. 
These preliminary matters being duly arranged, the transport 
dispatched, and proper dispositions made for giving mutual 
assistance to each other in case of touching on banks or rocks, 
you will at once cross the bar, and press forward to the scene of 
those operations which are so fully and clearly traced in the 
instructions drawn up by the Secretary of State, and which we 
hereby require and direct you to carry into execution. On those 
leading and specific objects of the Ex2)edition, we need not 
here enlarge nor do we intend by these orders in anywise to 
interfere with your plans for carrying them into effect, nor 
with the periods at which you may think it prudent to visit the 
various districts along the rivers. To those 2>rimary objects, all 
other pursuits and inquiries must be subordinate, but next in 
importance to them, or rather as an essential part of them, we 
place the extension of geographic discovery, and therefore while 
in the upper waters of the Quorra and Chadda, you will consider 
it a part of your duty to send forward Her Majesty’s ship 
‘ Soudan’ to the utmost limits of those rivers to which she can be 
floated with safety, and with a certainty that her return will not 
be intercepted by the falls of the water. Nor should your 
researches be bounded even by those limits, provided the season 
of the year, the disposition of the inhabitants, and the health of 
your own people are sufficiently encouraging to induce you to 
explore those rivers and their principal adjuncts still further into 
the interior by means of your boats. Such enterprizes, how- 
ever, must never consist of less than two well appointed galleys 
and commanded by an officer of intelligence. For these parties 
you will carefully select native interpreters, who have seen the 
nature and power of the steam-vessels, and witnessed your 
friendly and peaceable conduct, and who will declare among the 
various tribes that may be visited, the real purport of the Expe- 
dition, 
In framing the orders for these distant detachments, we desire 
that you will give the most peremptory directions that in no 
case whatever the two boats may be permitted to separate, — 
and that no over-confident individual may be allowed to straggle 
through the towns or villages, as an affray or some frivolous mis- 
understanding might mar all that you had already eftected. It 
is also our oi)inion that on these occasions it is bad policy to
