“I’ll give the fust bloke that tries it on a topper, so I will,” said Billy, fiercely, sitting down on his box and preparing to mount guard.

“I quite believe you,” said Jack, laughing. “But mind, Billy, you mustn’t make a noise or disturb him when he’s resting. And if anything special happens and I’m badly wanted, you must run to my office and fetch me. You know where it is?”

“Yaas, I know,” said Billy.

“If Mr Smith comes up, you may let him in and make yourself scarce till he goes away again.”

“What Mr Smith?” I asked.

“Oh, my fellow-lodger. Isn’t it funny his name’s Smith? At least, wouldn’t it be funny if every other person weren’t called Smith?”

“It is rather a large family,” said I, laughing.

I was rather doubtful whether his new employment was quite as congenial to him as his old. Indeed, I rather pitied him as he sat there silent and motionless like a watch-dog on guard.
