"Yes, sir."
"When can I start again?"
"To-morrow: there is a good day's work. Are you in a hurry, sir?"
"In a great hurry: I must set out again in an hour at the latest."
"It is impossible, sir."
"I will pay anything you ask."
"Impossible."
"Well, in two hours?"
"It is impossible for to-day; you will not be able to go on till to-morrow."
"My business cannot wait till to-morrow. Suppose, instead of mending this wheel, you were to put another on?"
