"I believe I must have made a conquest, he's always there, and whenever I'm in a hurry I can depend on him. I think he must refuse to carry any one else. It's an honour."

I ran through my loose change, and lit upon a half-sovereign, which I held conspicuously between thumb and first finger.

"He'll carry me," I said.
