“The man-machines!” I exclaimed, puzzled to know whatever he could mean.

“Yes, the men with wheels instead of legs, you know.”

“Oh, you mean the bicyclists,” I replied, laughing. “Have you really never seen any before?”

“No, indeed,” replied his Majesty. “Are they born with wheels on, or do they grow afterwards?”

I laughed, and fortunately just then the youngster opposite, who always rides to school on his bicycle, came out of doors wheeling his machine, and I was able to explain to the Wallypug the principle upon which they worked.

“Dear me; the Doctor-in-Law told me that the machinery was part of the man, but now I see that it is separate. And he charged me sixpence for the information too,” he complained, looking reproachfully at the Doctor-in-Law.

“Charged you sixpence!” I cried.

“Yes,” replied the poor Wallypug. “He offered to tell me all about them for sixpence, and as I was really very curious to know I gave it to him, and then he informed me that they were a peculiar race of people who came from Coventry, and who were all born with wheels instead of legs.”

“Take your old sixpence then, if you are going to make all that fuss about it,” said the Doctor-in-Law, crossly, throwing the coin down on the table and walking out of the room in a huff. “I’m sure I did read somewhere that they came from Coventry,” he added, popping his head in at the door and then slamming it violently after him.

The boy opposite was still riding up and down the road, and I made up my mind that although I had never spoken to him before, I would ask him to let the Wallypug examine his bicycle more closely.
