The transformation begun in Finn by the night he had spent in a rocking train, caged between a tiger and two bears, was enormously accentuated and confirmed by his encounter with the Professor. If zoologists had deliberately set themselves the task of converting an Irish Wolfhound into a wild beast, they could hardly have taken any more effective measures than those which had been adopted by pure chance with Finn, from the time at which he reached Sam's hands; and it is probable that no zoologist with any humanity in him would have made progress so extraordinarily rapid. The mere fact of being caged behind iron bars for the first time in his life, and that between a roaring, snarling tiger and two grunting little bears, strongly odoriferous of the wild, affected Finn in somewhat the same manner that a highly excitable and nervous man of quite untrained intellect might be affected by being flung into a cell, surrounded by raving maniacs. If such a man, after a dozen hours in his cell, were approached by some one whom he had every reason to regard as a friend and a rescuer, and beaten cruelly with a weapon possessed of strange and altogether horrible qualities--supernatural qualities, so far as he could tell--it is fair to suppose that he would be as much transformed by the ordeal as Finn was by his ordeal. Shortly after the episode of the red-hot iron, Finn's cage was again visited by Sam and the Professor, the former being laden with a big, blood-stained basket. From this basket the Professor took a large chunk of raw flesh, and pushed it through the bars into Finn's cage. A bone was also thrust through the bars, and a fixed iron pan near the gate was filled from outside with water. The Professor eyed Finn curiously while he performed these operations, and was surprised that the Giant Wolf, as they called him, did not spring forward upon the food. "I've put the fear of God into him all right, Sam," said the Professor. "He's not going to touch his grub while we're here. Like all wolves, he's mighty frightened of traps; and I guess he reckons there's a trap attaching to this meat. Watch how Killer tackles his."
