32(') FLAT ISLAND. 



23" 30' 30" S., which is two miles south of its posi- 

 tion in the chart. As we were detained by light 

 winds in the neighbourhood, I had more than one 

 opportunity of detecting this error. By midnight 

 we were about 18 miles N. by W. from Cape 

 Capricorn, when we felt a swell from the eastward, 

 which assured me there was an opening in the reefs 

 on the north side of the group of islets fronting the 

 Cape. 



Jtme 22. — There was a light air from S.W. till 

 near noon, then one from seaward which freshened 

 and became in the afternoon steady at S.E., a quarter 

 it afterwards prevailed from. We were at the time 

 passing about three miles from Flat Island, in *^7 

 fathoms, an increase in the soundings we had but 

 just got into. We were glad to find the ship's posi- 

 tion, fixed by points both far and near, agree with 

 the observations, a fact I can only account for here, 

 from the circumstance, that Flinders laid down the 

 coast about Port Bowen by observations on shore, 

 whereas that in the neighbourhood of Cape Capri- 

 corn, was from those made with the sea-horizon 

 which he found differ very materially. 



During the day we added to the chart the posi- 

 tion of two peaks, 1900 feet high, lying about 20 

 miles S.W. by W. from Cape Manifold, and forming 

 the northern end of a high rocky range. A current 

 was also noticed setting north a mile an hour. The 

 entrance of Port Bowen bore \A'.8.W. 15 miles at 

 midnight, when the depth was 30 fathoms.
