HYDROGRAPHY. 



strong, setting to the eastward ; the winds generally prevail from the 

 westward, and the weather is usually stormy. 



ROYAL COMPANY'S ISLE. 



The parallel of 49° 40' south, on which the Royal Company's Isle 

 is said to be situated, was examined by the Expedition, through eight 

 degrees of longitude, passing directly over the position assigned it. 

 There were no signs of it, or any indications of land, within the 

 search. 



MATHEWS ROCK. 



Mathew's Rock lies in the route of vessels bound from the Northern 

 Pacific to New South Wales. It is a very conspicuous object, rising 

 1186 feet above the sea, of conical shape, and a mile in circum- 

 ference. The position we place it in is 22° 27' south latitude, and 

 172° 10' 33" east longitude. 



AUCKLAND ISLANDS. 



The Harbor of Sarah's Bosom, in the Auckland Islands, was visited 

 by the Porpoise. Though a convenient harbor for whale ships, yet 

 it is not so good and safe to effect repairs in as that of Lawrie's, which 

 is secure from all winds. Sarah's Bosom lies in latitude 50° 38' 

 south, and longitude 166° 28' east. Some few vegetables may now 

 be obtained there. Wood and water can be procured in abundance, 

 and many kinds of fish. The best anchorage is in 10 or 12 fathoms 

 water. The Auckland Islands are of volcanic formation. The rocks 

 have much magnetic attraction. The highest point of the islands 

 does not exceed 1500 feet. The season for whaling in the neighbor- 

 hood is in April and May.
