as that they should sweep the broadest expanse of ocean 

 practicable, — and thence to the Feejee Islands, where he was 

 to select a safe harbor for whalers and public vessels of the 

 United States, and make such arrangements as would insure 

 their being furnished with supplies. 



From the Feejee Islands, he was to proceed to the port of 

 Sydney, and then make a second attempt to penetrate within 

 the Antartic region, south of Van Diemen's Land, and as far 

 west as longitude 45° East, or to Enderby's Land. The 

 squadron was then to rendezvous at Kerguelen's Land, usually 

 called the Isle of Desolation, and proceed to the Sandwich 

 Islands, where a store-ship from the United States would 

 meet them, in April, 1840. Thence they were to sail to the 

 Northwest Coast of America, and make surveys and exami-

 coast, they were to repair to that of Japan, — taking as many 

 doubtful islands as possible on their route, — and make a par-

 Sooloo, or Mindoro. Having completed this examination, 

 Lieutenant Wilkes was instructed to ascertain the disposi-

 commerce, their productions and resources ; after which he 

 was to proceed to the Straits of Sunda, — pass through the 

 Straits of Billiton, — touch at Singapore, where he would 

 meet a store-ship, — and then return home by the way of the 

 Cape of Good Hope. 



In addition to the orders necessarily suggested by the fore- 

 going instructions, Lieutenant Wilkes directed every officer 

 of the Expedition to keep a journal, in which everything that 

 occurred during the voyage was to be carefully noted. These 

 journals were to be weekly submitted to him for inspection, 

 and, on the return of the Expedition, to be disposed of ac- 

 cording to the directions of the Secretary of the Navy. The 

 scientific gentlemen were admonished to lose no opportunity 

 to procure information in their several departments. Meteo- 

 rological observations were required to be taken four times 

 daily ; and particular instructions were given to measure and
