"They are oval, my Lord. Therefore the carriages rise and fall."
"Yes, and pitch the carriage backwards and forwards: but how do they make it roll?"
"They do not match, my Lord. The end of one wheel answers to the side of the opposite wheel. So first one side of the carriage rises, then the other. And it pitches all the while. Ah, you must be a good sailor, to drive in our boat-carriages!"

"In that case I would gladly stay," replied Mein Herr. "As it isI fear I must say good-bye!"
"Where did you first meet him?" I asked Lady Muriel, when Mein Herr had left us. "And where does he live? And what is his real name?"
