"A cloud if you like, Willis; but do you know the weight of it you carry on your shoulders?"
"Well, it cannot be very great, otherwise I should feel it."
"What do you say to a ton or so, old fellow?"
"If you wish me to believe that, you will have to explain how, where, when, why, and wherefore."
"Very good. Willis; you have bathed sometimes?"
"Yes, certainly."
"In the sea?"
"Yes."
"Do you know what water weighs?"
"No, but I know that it is heavy."
