The young men elbowed their way in the crowd, and then discovered the cause of the merriment.

A gentleman in a tourist’s suit was standing on his head in the middle of the cab rank. He was cheered and encouraged by some of his boon companions, as well as the cab-drivers.

“Did you ever see such a consummate donkey—​the fool?” ejaculated Kempshead. “He calls himself a gentleman, I suppose?”

“Bravo—​bravo, well done!” shouted several of the throng.

The crowd grew denser and denser, and in a short time the pathway became blocked up.

A tall policeman came forward and addressed the simpleton who was making himself so ridiculous.

“Now, then, enough of this,” cried the constable. “Do you hear? Give over and move on.”

“All right, old man, I’m not hurting you or any one. Mind your own business, and I’ll mind mine.”
