Derrick was a strong man, and he recovered quickly.

In a day or two he was able to get about, and on the morning of the fifth he sought Mr.Bloxford and, as gently as he could, informed him that he, Derrick, would have to leave his employment.
Mr.Bloxford stared, grew red and exceeding wrath.
"What the deuce does this mean ?" he demanded, throwing open his fur coat and sticking out his chest.

"Look here, if you're not satisfied----" Derrick made haste to assert not only his entire satisfaction with, but his gratitude for, Mr.Bloxford's confidence and generosity.
"Then what is it ?" shrilled Mr.Bloxford.

"Has anybody been roughing you?
If so, out he goes.

Oh, I can't part with you, and that's the long and short of it.
