It was not really a bridge at all. It was only the eastern extremity of the Serpentine; but as the boy leant over the stone balustrade, and gazed upon the artificial flood, broadening out indefinitely in the darkness, it might have been the noblest river in the world. Its banks were muffled in a feather boa of trees, bedizened by a chain of many lights; the lights of a real bridge made a diadem in the distance; and between these sped the lamps of invisible vehicles, like fretful fireflies. And the still water gave back every glimmer with its own brilliance, unchallenged and undimmed by moon or star, for not a trace of either was in the sky; and yet it was the most wonderful sky the boy had ever seen—a black sky tinged with sullen rose, or a red sky seen through smoked glasses, he hardly knew which he would have called it. But he did know that warm and angry glow for the reflection of London’s light and life; he could not forget he was in London for a moment. Her mighty machinery with its million wheels throbbed perpetually in his ears; and yet between the beats would come the quack of a wild duck near at hand, the splash of a leaping fish, the plaintive whistle of water-fowl: altogether such a chorus of incongruities as was not lost upon our very impressionable young vagabond. The booming strokes of eleven recalled him to a sense of time and his immediate needs. His great adventure was still before him; he pushed on, bag in hand, to select its scene. Another road he crossed, alive with the lamps of cyclists, and came presently upon a wide space intersected with broad footpaths from which he shrank; it was altogether too public here; he was approaching an exposed corner in an angle of lighted streets, with the Marble Arch at its apex, as a signboard made quite clear. He had come right across the Park; back over the grass, keeping rather more to the right, in the direction of those trees, was the best thing now. It was here that he found the grass distinctly damp; this really was enough to deter an asthmatic, already beginning to feel asthmatical. Pocket Upton, however, belonged to the large class of people, weak and strong alike, who are more than loth to abandon a course of action once taken. It would have required a very severe attack to baulk him of his night out and its subsequent description to electrified ears. But when bad steering had brought him up at the bandstand, the deserted chairs seemed an ordained compromise between prudence and audacity, and he had climbed into the fenced enclosure when another enormous policeman rose up horribly in its midst. “What are you doing here?” inquired this policeman, striding upon Pocket with inexorable tread. “No harm, I hope,” replied our hero humbly, but with unusual readiness. “Nor no good either, I’ll be bound!” said the policeman, standing over him.
