May 28, I860.] ADMIRALTY SURVEYS— CANADA. 155 



and China. Tlie coasting charts, twelve in number, on various 

 scales, published by the Trinity House, Adelaide, under the direc- 

 tions of B. Douglas, Esq., and accompanied by sailing directions, 

 will be duly appreciated by mariners visiting those parts of Aus- 

 tralia. In Tasmania, Mr. Smith, r.n., of H.M.S. Herald, has made 

 a plan of Hobarton, on the scale of 6 inches to a mile, which will 

 be immediately engraved and published. The map of Tasmania, in 

 four sheets, scale -stt.wo-j or about 5 miles to an inch, by James 

 Sprens, Esq., Surveyor-General, is coloured to distinguish the 

 coimties, gives soundings, and is apparently the largest and best 

 map published. 



British Columbia. — The surveying party, under our associate Cap- 

 tain George Eichards, in H.M.S. Plumper, consisting of Messrs. 

 Bull and Pender, masters. Lieutenant Mayne and Mr. Bedwell, 

 second master, have, as usual, worked most industriously during 

 the past season. They have surveyed Pitt and Frazer rivers, with 

 the magnificent opening of Burrard Inlet, which carries water deep 

 enough for a line-of-battle ship, up to within 3 miles, overland, to 

 the site of the capital, New Westminster. Also parts of the east 

 coast of Vancouver Island, with the adjacent channels, in the course 

 of which they have examined 700 miles of coast, while Lieutenant 

 Mayne has explored 500 miles of the Upper Frazer. They have 

 sounded thoroughly over 420, and partially over 400 square miles, 

 the greatest depth between Vancouver Island and the main being 

 230 fathoms. The coast line has been laid down on the scale of 

 3 inches, plans of harbours and Frazer and Pitt rivers on 6 inches, 

 and Victoria harbour on 24 inches to a mile. Mr. Bedwell has con- 

 tributed also some very characteristic sketches of scenery in these 

 regions. 



Canada. — In the St. Lawrence survey Commander Orlebar divided 

 his staff of assistants into two parties ; Commander Hancock, with 

 Messrs. Desbrisay and Carey, having re-examined the river between 

 Montreal and Quebec, and inserted all the changes consequent upon 

 the improvements carried out by the Montreal Harbour Commis- 

 sioners ; while Commander Orlebar, with Mr. Clifton, returned to 

 the coast of Labrador and the Strait of Belleisle, where several 

 positions were redetermined, and numerous soundings taken. In 

 the course of the survey 370 miles of coast were re examined, and 

 1430 linear miles of soundings run. The charts of the Upper St. 

 Lawrence, in twelve sheets, on the scale of 2 inches to a mile, 

 are in the hands of the engraver, and will be published in July.
