Having said so much, it is hardly necessary to add that Finn suffered greatly during the next few weeks of his life; for had not the Professor sworn to make the Giant Wolf his obedient creature, and a docile performer in the circus? That he never did. His boast was never made good, though with a real wolf it might have been; and again it almost certainly would have been, had he ever guessed that Finn was not a wolf at all, but one of the most aristocratic hounds and friends of man ever bred. But his failure cost Finn dear, in pain, humiliation, fear, and suffering of diverse kinds. The boss jeered at the Professor when the failure to tame Finn had extended over a week; and that added greatly to the severity of Finn's ordeal. The Professor was on his mettle; and now, while he made no further spoken boasts, he swore to himself that he would break the Giant Wolf's spirit or kill him. He never guessed that his whole failure rested upon one initial mistake. To the wild beast the red-hot iron bar was merely the terrible insignia of the Professor's indubitable might and mastery; a very compelling invitation to docility and respectful obedience. To Finn it was not that at all; but merely terrible and unmistakable evidence of basest treachery and malevolent madness. And it was largely with the red-hot iron that the Professor sought to tame Finn, believing, as he did, that this was necessary to his own, the Professor's, preservation. Upon one occasion--one brilliantly sunny morning of Finn's martyrdom--it did dimly occur to the Professor that it might be the hot iron which somehow stood between himself and the mastery of Finn. Accordingly, he twisted some wire round the end of his quilt, or cutting whip, and entered the cage without the iron, while Sam stood outside with the brazier, ready to pass in the iron if that should prove necessary. Finn absolutely mistrusted the man, of course--he had suffered what he believed to be the man's insane lust of cruelty for a fortnight now--but yet he saw that the iron was not in the cage, and so he made no hostile demonstration; and that was a notable concession on his part, for, of late, the Professor's tactics, so far from taming him, had taught the naturally gracious and kindly Wolfhound to fly at the man with snapping jaws the instant he came within reach. Now the man moved slowly, very slowly, nearer and nearer to Finn's corner, using ingratiating words. When it seemed that he meant to come near enough for touch, Finn decided that he would slip across the cage to its opposite far corner in order to avoid the hated contact. He did not snarl; he did not even uncover his fangs, for the fiery instrument of torture was not there. He rose from his crouching position, and of necessity that brought him a few inches nearer to the Professor, before he could move toward the far side of the cage.
