208 Report of the Voyage of Discovery 
operations of the Coquille. The general chart of it which 
M. Duperrey has made will rectify many errors. Benham Island 
is there represented according to the observations which M. 
de Blosseville made. Ualan Island, which the American Cap- 
tain Crozier named Strong, and to which M. Duperrey has 
restored the name which the inhabitants give it, merits parti- 
cular interest. During a stay of fifteen days, the officers of 
the corvette went over it in every direction; they found there 
some tolerably large ports: one, which the inhabitants call 
Lélé, and another which has received the name of the Coquille, 
are laid down in the atlas, after the very detailed operations of 
Messrs. Berard, Lottin, and de Blois. 
M. de Blois has besides made a complete survey of the 
islands Tougoulon and Pelepap, which are probably the Mac- 
Askill of certain maps; and also of the islands Mougoul, Ougai, 
and Aoura, which were discovered on the 18th of June. It is 
also to this officer we owe the detailed plan of the rather ex- 
tended group of Hogoleu, of which father Cantova had al- 
ready formerly spoken; and in the midst of which the Co- 
quille navigated, the 24th of June 1824. ‘The survey made by 
M. Lottin of the islands Tametain, Fanadik, and Holap, 
unites in these latitudes the operations of the Coquille to those 
of the Uranie. 
The three last sheets of this rich atlas, an analysis of which 
we have just given, represent the anchorages of Saint-Helena 
and of Sandy Bay, and the island of Ascension, from the ob- 
servations of all the officers. 
Charts are not the less improved, when freed from islands, 
rocks and sand-banks which do not exist, than when newly 
discovered lands are inserted inthem. ‘The expedition of the 
Coquille will have rendered more than one service in this re- 
spect. 
According to most geographers, there is, not far from the 
eastern coasts of Peru, a rock named the Trepied. M. Du- 
perrey has sought for it in vain: the Coquille went full sail over 
the very places where the Trepied is generally laid down. 
Whilst standing along the coasts of New Guinea, M. Du- 
perrey sought with great care, but without success, for the isles 
which Carteret had named Stephens’ Islands. According to 
him, these islands, still represented in our maps, would be the 
Providence Islands of Dampier, situated at the opening of 
Geelving Bay: this is also the opinion of Captain Krusenstern, 
and it cannot be denied that it is now avery probable one. It 
will nevertheless seem very strange that Carteret should have 
been deceived by nearly three degrees in his reckoning. 
Our most modern maps place a group of isles called the 
Trials,
