Even as I thought that thought, Charles appeared to form a sudden and resolute determination.  With one lightning swoop he seized the doctor’s hair in his powerful hand, and tried to lift it off bodily.  He had made a bad guess.  Next instant the doctor uttered a loud and terrified howl of pain, while several of his hairs, root and all, came out of his scalp in Charles’s hand, leaving a few drops of blood on the skin of the head in the place they were torn from.  There was no doubt at all it was not a wig, but the Kentuckian’s natural hirsute covering.

The scene that ensued I am powerless to describe.  My pen is unequal to it.  The doctor arose, not so much angry as astonished, white and incredulous.  “What did you do that for, any way?” he asked, glaring fiercely at my brother-in-law.  Charles was all abject apology.  He began by profusely expressing his regret, and offering to make any suitable reparation, monetary or otherwise.  Then he revealed his whole hand.  He admitted that he was Sir Charles Vandrift, the famous millionaire, and that he had suffered egregiously from the endless machinations of a certain Colonel Clay, a machiavellian rogue, who had hounded him relentlessly round the capitals of Europe.  He described in graphic detail how the impostor got himself up with wigs and wax, so as to deceive even those who knew him intimately; and then he threw himself on Dr. Quackenboss’s mercy, as a man who had been cruelly taken in so often that he could not help suspecting the best of men falsely.  Mrs. Quackenboss admitted it was natural to have suspicions—­“Especially,” she said, with candour, “as you’re not the first to observe the notable way Elihu’s hair seems to originate from his forehead,” and she pulled it up to show us.  But Elihu himself sulked on in the dumps:  his dignity was offended. “If you wanted to know,” he said, “you might as well have asked me.  Assault and battery is not the right way to test whether a citizen’s hair is primitive or acquired.”

“It was an impulse,” Charles pleaded; “an instinctive impulse!”

“Civilised man restrains his impulses,” the doctor answered.  “You have lived too long in South Africa, Mr. Porter—­I mean, Sir Charles Vandrift, if that’s the right way to address such a gentleman.  You appear to have imbibed the habits and manners of the Kaffirs you lived among.”

For the next two days, I will really admit, Charles seemed more wretched than I could have believed it possible for him to be on somebody else’s account.  He positively grovelled.  The fact was, he saw he had hurt Dr. Quackenboss’s feelings, and—­much to my surprise—­he seemed truly grieved at it.  If the doctor would have accepted a thousand pounds down to shake hands at once and forget the incident—­in my opinion Charles would have gladly paid it.  Indeed, he said as much in other words to the pretty American—­for he could not insult her by offering her money.  Mrs. Quackenboss
