promise of finding such a port ; but, perhaps, inside the 

 reefs beyond Peak Point, or more hkely between Albany 

 Island and the main, a snug place may be discovered for 

 that purpose. 



" In tracing out the approach to BHgh's Farewell, you 

 will be led to examine the southern face of New Guinea as 

 far as Cape Valsche ; but after verifying the position of 

 this point, it will be prudent to quit the shores of that 

 island, and not to meddle with any part of it over which 

 the Dutch claim jurisdiction. 



"When you have arrived at this distant point, the 

 S.E. monsoon will probably render it necessary to repair 

 to Port Essington for such supplies as may by previous 

 arrangement have been sent there for you from Sydney ; 

 or perhaps unforeseen events might render it more expe- 

 dient to proceed for refreshments to some of the islands 

 in the Arafura Sea, or it is possible to one of the Dutch 

 settlements in Java. And in either of these two latter 

 cases you should make a complete survey of the island to 

 which you have proceeded, or you should select any one of 

 the eastern passages from Bally to Floris most convenient 

 to the object you have in view, and then lay it down with 

 precision. Of the many well-known passages between the 

 innumerable islands of that great Archipelago, there is not 

 one which has ever been charted with plausible accuracy ; 

 and it cannot be too strongly impressed on your mind that 

 hydrography is better served by one accurate chart than 

 by ten approximate sketches. 



" The several objects of this highly interestiug expe- 

 dition having thus been briefly enumerated, I have only 

 to remind you that their Lordships do not prescribe to you 

 the order in which they are to be executed, leaving it to 

 your own prudence, and to your experience in those cli- 

 mates, so to arrange them tjiat each part of your survey
