As the marble image of Washington came into view the cheers of the assembled thousands were only outvied by the cannon in the square, and the national hymn was for the time drowned in the enthusiasm of the event. The President of the Washington Monument Association Mr. GEORGE F. GORDON, in an appropriate address to the Mayor and Select and Common Councils, presented the beautiful monument to the city. It was received by the Mayor, Hon. DANIEL M. FOX, in a suitable reply, and the benediction being pronounced, this most interesting event became part of the brightest of Philadelphia’s chronicles. * * * * * The munificence of our fellow-townsman, W. W. Corcoran, Esq., has been handsomely acknowledged by the National Academy of Design, at New York, which has transmitted to him congratulatory resolutions with reference to his recent foundation of a gallery of art in this city.—_Washington Chronicle._ NEW SOUTH WALES. Our latest files are to April 21st, inclusive. Sydney was at that time in high spirits over the recent visit of the Prince Captain of H. M. S. _Gallatea_. The most noteworthy action of whom was the laying of the corner-stone of the testimonial to the hardy navigator and discoverer, Captain Cook. We extract the remarks of the leading journal of Sydney. “THE CAPTAIN COOK MEMORIAL.—A monument to the memory of Captain Cook will be rather an expression of our admiration for his character and services than an enhancement of his fame. The last generation was filled with wonder at the narrative of his discoveries. The first quartos that record them display in most striking forms the scenes and objects he made known to the world. He visited many islands of the Southern seas, whose voluptuous and animated social life attracted as to a new-found Paradise. Subsequent experience scattered the illusions of fancy, but brought out more clearly the value of his labors. New South Wales presented to his view a land of savages, lowest in the scale of civilization, but it also offered a noble field for British colonization, perhaps less appreciated while America was still a dependency of England, but brought into notice a few years after that country ceased to belong to the Crown. “COOK first landed at Botany Bay, on the 19th of April, and on the 23d of August, he took possession of the entire country in the name of the SOVEREIGN of England. The precise spot where he anchored is marked in the charts by a nautical symbol, and can thus be identified. On reaching the shore he found a spring of water ample for the wants of the ship, and tradition has reported that he bent his knees in adoration of the Supreme Being.
