"An earthquake," somebody said at length. "An earthquake, beyond doubt, and a pretty bad one at that. That accounts for the failure of the electric light. There will be some bad accidents if the gas mains are disturbed."

The earth grew steady underfoot again, the white flakes ceased to fall. Amongst the men the spirit of adventure was rising; the idea of standing quietly there and doing nothing was out of the question.

Anyway, there could be no further thought of pleasure that night. There were many mothers there, and their uppermost thought was for home. Never, perhaps, in the history of royalty had there been so informal a breaking up of a great function. The King and Queen had retired some little time before—a kindly and thoughtful act under the circumstances. The women were cloaking and shawling hurriedly; they crowded out in search of their carriages with no more order than would have been obtained outside a theatre.

But there were remarkably few carriages in waiting. An idiotic footman who had lost his head in the sudden calamity sobbed out the information that Oxford Street and Bond Street were impassable, and that houses were down in all directions. No vehicles could come that way; the road was destroyed. As to the rest, the man knew nothing; he was frightened out of his life.

There was nothing for it but to walk. It wanted two good hours yet before dawn, but thousands of people seemed to be abroad. For a space of a mile or more there was not a light to be seen. Round Buckingham Palace the atmosphere reeked with a fine irritating dust, and was rendered foul and poisonous by the fumes of coal gas. There must have been a fearful leakage somewhere.

Nobody seemed to know what was the matter, and everybody was asking everybody else. And in the darkness it was very hard to locate the disaster. Generally, it was admitted that London had been visited by a dreadful earthquake. Never were the daylight hours awaited more eagerly.

"The crack of doom," Sir George Egerton remarked to his companion, Lord Barcombe.

They were feeling their way across the park in the direction of the Mall.

"It's like a shuddering romance that I read a little time since. But I must know something about it before I go to bed. Let's try St. James's Street—if there's any St. James's Street left."

"All right," Lord Barcombe agreed, "I hope the clubs are safe. Is it wise to strike a match with all this gas reeking in the air?"
