The Fleet and its ditch, with their unsavoury reputations, have been filled up. The Regent's Canal, which enters the Thames below Wapping, winds its way, now above ground and occasionally beneath, as a sort of northern boundary of London proper. Of other waterways, there are none on the north, while on the south there are but two minor streams, Beverly Brook and the River Wandle, which flow sluggishly from the Surrey downs into the Thames near Wandsworth.

As for elevations, the greatest are the four cardinal points before mentioned.

Tower Hill, with its rather ghastly romance, is first and foremost in the minds of the native and visitor alike. This particular locality has changed but little, if at all, since Dickens' day. The Minories, the Mint, Trinity House, the embattled "Tower" itself, with the central greensward enclosed by iron railings, and the great warehouses of St. Katherine's Dock, all remain as they must have been for years. The only new thing which has come into view is the garish and insincere Tower Bridge, undeniably fine as to its general effect when viewed from a distance down-river, with its historic background and the busy activities of the river at its feet. A sentiment which is speedily dispelled when one realizes that it is but a mere granite shell hung together by invisible iron girders. Something of the solidity of the Tower and the sincerity of a former day is lacking, which can but result in a natural contempt for the utilitarianism which sacrifices the true art expression in a city's monuments.

Of the great breathing-places of London, Hyde Park ranks easily the first, with Regent's Park, the Green Park, St. James' Park, Battersea Park, and Victoria Park in the order named. The famous Heath of Hampstead and Richmond Park should be included, but they are treated of elsewhere.

Hyde Park as an institution dates from the sixteenth century, and with Kensington Gardens—that portion which adjoins Kensington Palace—has undergone no great changes during the past hundred years.

At Hyde Park Corner is the famous Apsley House presented by the nation to the Duke of Wellington. At Cumberland Gate was Tyburn. The "Ring" near Grosvenor Gate was the scene of gallantries of the days of Charles II.; of late it has been devoted to the games of gamins and street urchins. The Serpentine is a rather suggestively and incongruously named serpentine body of water, which in a way serves to give a variety to an otherwise somewhat monotonous prospect.

The first Great International Exhibition was held in Hyde Park in 1851, and rank and fashion, in the mid-Victorian era, "church paraded" in a somewhat more exclusive manner than pursued by the participants in the present vulgar show. The Green Park and St. James's Park touch each other at the angles and, in a way, may be considered as a part of one general plan, though for a fact they vary somewhat as to their characteristics and functions, though under the same "Ranger," a functionary whose office is one of those sinecures which under a long-suffering, tax-burdened public are still permitted to abound.

The history of Regent's Park, London's other great open space, is brief. In 1812, the year of Dickens' birth, a writer called it "one of the most fashionable Sunday promenades about town." It certainly appears to have been quite as much the vogue for promenading as Hyde Park, though the latter retained its supremacy as a driving and riding place. The Zoological Gardens, founded in 1826, here situated, possess a perennial interest for young and old. The principal founders were Sir Humphrey Davy and Sir Stamford Raffles.

The rambler in old London, whether he be on foot or in a cab, or by the more humble and not inconvenient "bus," will, if he be in the proper spirit for that edifying occupation, be duly impressed by the mile-stones with which the main roads are set. Along the historic "Bath Road," the "Great North Road," the "Portsmouth Road," or the "Dover Road," throughout their entire length, are those silent though expressive monuments to the city's greatness.

In old coaching days the custom was perhaps more of a consolation than it proves to-day, and whether the Londoner was on pleasure bent, to the Derby or Epsom, or coaching it to Ipswich or Rochester,—as did Pickwick,—the mile-stones were always a cheerful link between two extremes.
