For the better part of Piccadilly things were brighter. Evidently the explosion had had a straight run here, for the road had been raised like some mighty zigzag molehill for many yards. The wood pavement scattered all over the place suggested a gigantic box of child's bricks strewn over a nursery floor. The tube had been forced up, its outer envelope of concrete broken so that the now twisted steel core might have been a black snake crawling down Piccadilly. Doubtless the expanding air had met with some obstacle in the tube under St. James's Street, hence the terrible force of the explosion there.

There was quite a large crowd in Oxford Street. The whole roadway was wet; the gutters ran with the water from the broken pipes. The air was full of the odour of gas. All the clocks in the streets seemed to have gone mad. Lord Barcombe glanced at his own watch, to find that it was racing furiously.

"By Jove!" he whispered excitedly, "we're in danger here. The air is full of electricity. I went over some works once, and neglected to leave my watch behind me, and it played me the same prank. It affects the mainspring, you know."

There were great ropes and coils of electric wire of high voltage cropping out of the ground here and there; coils attached to huge accumulators, and discharging murderous current freely. A dog, picking his way across the sopping street, trod on one of the wires, and instantly all that remained of the dog was what looked like a twisted bit of burnt skin and bone. It appealed to Sir George Egerton's imagination strongly.

"Poor little brute!" he murmured. "It might have happened to you or me. Don't you know that a force that only gives a man a bad shock when he is standing on dry ground often kills him when the surface is wet? I wonder if we can get some indiarubber gloves and galoshes hereabouts. After that gruesome sight, I shall be afraid to put one foot before the other."

Indeed, the precaution was a necessary one. A horse attached to a cab came creeping over the blocked streets; the animal slipped on a grating connected with the ventilation of the drains, and a fraction of a second later there was no horse in existence. The driver sat on his perch, white and scared.

"The galoshes," Lord Barcombe said hoarsely. "Don't you move till we come back again, my man. And everybody keep out of the roadway."

The cry ran along that the roadway meant instant death. The cabman sat there gibbering with terror. A little way further down was a rubber warehouse, with a fine selection of waders' and electricians' gloves in the window. With a fragment of concrete Sir George smashed in the window, and took what he and Lord Barcombe required. They knew that they would be quite safe now.
