central keep of which was built in 1078 by Gundulph, Bishop of Rochester, in obedience to the command of William the Conqueror. By the side of this historic pile is the Tower Bridge, the marvellous engineering feat of Sir Horace Jones and Sir J. Wolfe Barry. It opens upwards in the centre to allow the shipping to pass through. Right away towards the east are the great docks, the principal of which are the London Docks and the East India Docks. Passing west of the city are the great Law Courts in the Strand, designed by Streeter. Behind them is Lincoln's Inn, and in front across Fleet Street, is the Temple. Gray's Inn is in Holborn, as well as Staple Inn, with the picturesque old-fashioned frontage, once the prevailing style of London's domestic architecture. Smaller Inns are Clifford's Inn, threatened with demolition, with Old Serjeant's Inn adjoining, while Serjeant's Inn is on the other side of Fleet Street, nearer to Ludgate Circus, and not far from the Temple. In Trafalgar Square a priceless collection of old masters' paintings are housed in the National Gallery, once the premises of the Royal Academy of Arts, who moved to Burlington House, Piccadilly. Regent Street, with its shops, and Bond Street, the great centre for art dealers and picture galleries, hardly require further description. The British Museum, the South Kensington Museum, and numerous others; the great hospitals,--St. Bartholomew's, Guy's, Charing Cross, and many more equally as well known; the wonderful open spaces as typified by Hyde Park; the Palaces of Buckingham, St. James, and Kensington; besides the Cathedral of St. Paul, the Abbey, and Houses of Parliament, Westminster, with the newly erected Roman Catholic Cathedral, close to Victoria Station, comprise only a tithe of what can be seen in the capital of the British Empire.
