At this spot Mr. Decimus Burton had already built the great Triumphal Arch forming the entrance to Constitution Hill, together with the Classic Screen at Hyde Park Corner. The Screen was built in 1828, and the Arch, which is a copy of the Arch of Titus at Rome, in 1832. Already, in 1820, Apsley House had become the residence of the Iron Duke, but it was not until 1846 that what Thackeray justly names ‘the hideous equestrian monster’ was placed on the summit of that Arch, opposite the Duke’s windows. Here is an illustration of it, before it was hoisted up to that height. Beside it you see the Duke himself, in his characteristic white trousers, in company with several weirdly dressed persons. Again, over page, may be seen the Arch, with the statue on it, and the neighbourhood vastly changed from the appearance it wears in the picture of the ‘North-East Prospect of St. George’s Hospital.’ Instead of the great hooded waggons starting for the West Country, the road is occupied with very crowded traffic, and among the vehicles may be noticed two omnibuses, one going to Chelsea, the other (for this is the year 1851) to the Exhibition,--the first exhibition that ever was. If, ladies and gentlemen, you will be pleased to look at those omnibuses, you will see that they have neither knifeboards nor seats on the roof, and that passengers are squatting up there in the most supremely uncomfortable, not to say dangerous, positions. Also, in those dark ages of London locomotion, the ascent to that uncomfortable roof was of itself perilous, for no [Illustration: THE WELLINGTON ARCH AND HYDE PARK CORNER, 1851.] [Illustration: ST. GEORGE’S HOSPITAL, AND THE ROAD TO PIMLICO, 1780.] one had as yet dreamed of the staircase. Other curious points will be noticed by the observant, and among them the fact that ’buses then had doors. The present historian vividly recollects a door being part of the equipment of every ’bus, and of the full-flavoured odour of what Mr. W. S. Gilbert calls ‘damp straw and squalid hay’ which assailed the nostrils of the ‘insides’ when that door was shut; but in what particular year did the door vanish altogether? Alas! the straw, with the door, is gone for evermore, and passengers no longer lose their small change in it to the great gain of the conductor, who, by the way, used to be called ‘the cad,’ even although he commonly wore a ‘top hat’ and a frock coat, as per the picture. The word ‘cad’ has since then acquired a much more offensive meaning, and if you addressed a conductor by that name nowadays, he would probably express a desire to punch your head. The hideous statue of the Duke and his charger ‘Copenhagen,’ which the French said ‘avenged Waterloo,’ was removed to Aldershot in 1884, when the alterations were made at Hyde Park Corner. VII And now we come to the first toll-gate, which, removed to this spot in 1825, opposite where the Alexandra Hotel now stands, stood here until 1854.
