doubtless the long* sought Trial Rocks of former naviga¬

In December, 1841, the Beagle anchored in Gage’s 
Roads, Swan River, and on the 12th proceeded to examine 
the coast in the neighbourhood of 22° S., which is named 
Port Grey in Arrowsmith’s maps. We returned to our 
anchorage on the 18th, having come to the conclusion 
that Champion Bay, placed twelve miles south of its true 
position, is the place erroneously described as Port Grey. 
Our observations at Koombanah Bay placed Point 
Casuarina and Cape Naturaliste four miles south of their 
present position. 
We then visited Adelaide, where we laid down the 
eoast from Holdfast Bay to the Port of Adelaide, which 
we found a perfect dock, navigable for vessels drawing 
fifteen feet. 
We arrived at Portland Bay in January, 1842, where 
our observations make the Glenelg two miles further 
Within the Port Phillip boundary than it has been hitherto 
reckoned. As we passed S.W. Cape on our way to Hobart 
Town, we made it 42° 35' south. 
His "Excellency Sir John Franklin was good enough to 
place the Tasmanian Government cutter Vansittart 
under my directions, for the purpose of expediting the 
survey of Bass’ Strait; and this assistance was the more 
valuable as orders arrived for the Beagle’s return to 
England, which left a very short time for the performance 
of this important duty. 
We found Cape Howe placed about eight miles too far 
east, and Twofold Bay nearly the same in error; nor is 
any part of the coast up to Botany Bay correctly laid 
down in the present charts. But it must he recollected 
that the illustrious Flinders in his survey of this part had 
to struggle with immense difficulties. He had at the time
