The Harbour Commissioners have reported that none of the exieting harbours, front the Thames to Portsmouth, are eapehle of being con- verted into harbours for Government armed steams: rs: they therefore recommend the formation of three fresh once —one from Beaehy lleed to. Langley Point, one at the cliffs east of Margate, and one under the thlTs to the eastward of the present Dover harbour. The fresh harboure to be formed by two breakwaters, with side-piers, which will leave entrances S.W.S. and S.E., to enclose about three hundred acres, and to have six feet water at the lowest neap-tide. Mr. Enderby has fitted out an expedition for the purpose of exploring the Antarctic regions. France and the United States have recently sent out ships or discovery to the same latitudes; and it is believed that Captain D'Urville, the commander of the French expedition, has dis- covered an island to the southward of Van Diemen's Land. The expe- dition of which Mr. Enderby is the promoter will entail no expense on the English Government, while it will carry out all the views which
Government entertained when Captain Ross was sent out. The officer to whom Mr. Enderby's expedition lots been intrusted is Captain Maple- ton, a fellow-voyager with Captain Itoss.—Times.
