The Mansion House stands on the site of the old Stocks Market, where a pair of stocks formerly stood, which were the terror of those who dealt in stale fish or otherwise offended. A little more than a century ago, the market was removed to opposite the Fleet Prison, and is still held there, under the name of Farringdon Market. In Suffolk-lane stands the Merchant Taylors' School, built on the site of a mansion that formerly belonged to the Suffolk family; hence the next turning is called "Duck's-foot-lane"--no doubt a corruption of "Duke." The present building was erected a few years after the Great Fire, although there have been additions made to it as recently as twenty years ago. Many very eminent men have been educated at this school; amongst them James Shirley, the dramatist, and author of that beautiful poem commencing with-- "The glories of our birth and state Are shadows--not substantial things; There is no armour against fate-- Death lays his icy hand on kings." In Thames-street, we have still a building bearing the name of Steelyard or Stilliard, an old name still in use in the country for the beam balance on which the portions of a pound are notched on the one side, with figures giving the number of pounds, and a hanging and sliding weight. It is principally used by butchers, and is known by no other name than that of stilliards in the north of England: hence, no doubt, the name of this ancient haunt of the Hanse merchants. The last church on the west side of London Bridge, in Upper Thames-street, is called Allhallows-the-Great; it was built by Wren, and contains a carved screen, presented by the Hanse merchants, who obtained a settlement in England a century or two after the Norman Conquest. At the Old Swan Pier, or Swan stairs, timid passengers were wont to land who had not courage enough to remain with the waterman in his wherry, and shoot the dangerous arches of old London Bridge, but generally walked on to some other landing-place below the bridge, where they again embarked. New London Bridge is built of granite; and was first opened by William IV. and the good Queen Adelaide, in 1831. It cost nearly two millions sterling. In King William-street stands the statue of King William IV., by Nixon, looking towards London Bridge. This statue, which is of granite, cost upwards of 2000_l._, of which 1600_l._ was voted by the Common Council of London. It is considered an admirable likeness; and the folds of the cloak are beautifully arranged, while the coil of rope reminds us of the "Sailor King." The width and beauty of King William-street is very striking, especially after emerging from the narrow streets and hilly lanes which we have just described.
