One of the most striking and gigantic buildings in St. Petersburg is the Admiralty. The principal front on the land side is considerably more than one-third of an English mile in length, and its wings, in depth, extend six hundred and seventy two feet, down to the edge of the Neva, this noble river forming the fourth side of the quadrangle. Within the three sides (the Neva and two wings) are ranges of parallel buildings, which form the magazines, artificers' shops, mast and boat houses, offices, &c.; and in the area within these are four slips for building the largest, and two for a smaller class of ships of war. The whole of the outer range of buildings consists of grand suites of rooms, and long and beautifully ornamented galleries, filled with the natural history and curiosities collected in every part of the globe, and brought by the different navigators which Russia, of late years, has sent forth on discovery. In one room are assembled all the different nautical and mathematical instruments; in another all the models of ships of different nations and different eras; in another a complete library connected with every branch of the marine service.--_Granville's Travels_. * * * * * _Printed and Published by J.
