And each passed on to his affairs.

"Now for William; we must find William, or the joke will be on Robert."

He manoeuvered his way through the congested thoroughfare, searching the faces of the grooms and footmen. He dodged hither and thither, and was once brought to a halt by the mounted police.

"Here, you! What d'ye mean by runnin' around like this? Lost yer carriage, hey? I've a mind to run ye in. Y' know th' rules relatin' th' leavin' of yer box in times like these. Been takin' a sly nip, probably, an' they've sent yer hack down a peg. Get a gait on y', now."

Warburton laughed silently as he made for the sidewalk. The first man he plumped into was William—a very much worried William, too. Robert could have fallen on his neck for joy. All was plain sailing now.

"I'm very glad to see you, sir," said William. "I was afraid you could not get them clothes on, sir. I was getting a trifle worried, too. Here's the carriage number."

Warburton glanced hastily at it and stuffed it into a convenient pocket.

"It's sixteen carriages up, sir; a bay and a gray. You can't miss them. The bay, being a saddle-horse, is a bit restive in the harness; but all you have to do is to touch him with the whip. And don't try to push ahead of your turn, or you will get into trouble with the police. They are very strict. And don't let them confuse you, sir. The numbers won't be in rotation. You'll hear one hundred and fifteen, and the next moment thirty-five, like as not. It's all according as to how the guests are leaving. Good luck to you, sir, and don't forget to explain it all thoroughly to Mr. Warburton, sir."

"Don't you worry, William; we'll come out of this with colors flying."

"Very well, sir. I shall hang around till you are safely off,"—and
William disappeared.
