ADMIRALTY INSTRUCTIONS. 19 



George Sound, the dangerous patch off Kangaroo 

 Island, and many others, of which accounts are 

 given in the above work, ought, if possible, to be 

 examined, as more immediately appertaining to 

 your own field. Whenever found, the depth, nature, 

 and limits of the banks on which they stand, should 

 be determined, as they might prove to be of suffi- 

 cient extent to give warning to the danger, and 

 then a direct course should be immediately made 

 by the ' Beagle' to the nearest land, where a con- 

 venient place should be selected, and its position 

 carefully ascertained. 



"At Swan River you will have previously learnt 

 from Lieutenant Roe, the Surveyor-General, whether 

 the above mentioned rocks off Kangaroo Island, 

 have been again seen, or their position altered, 

 since Captain Brockman's first description, so as to 

 save your time in the search. 



" You will no doubt obtain from that intelligent 

 officer. Lieutenant Roe, much important informa- 

 tion respecting the north-west coast, as well as all 

 the detached intelligence, which during his long 

 residence there he must have collected, relating to 

 every part of the shores of New Holland, From 

 him, also, you will acquire many useful hints about 

 the places in the Indian Sea where refreshments 

 may be obtained, as well as some insight into the 

 disposition of the authorities and the inhabitants 

 whom you will meet there, and he will probably be 

 able to give you a clear account of the duration of 

 the monsoons and their accompanying weather.
