His heart went out in pity toward the miserable crew, but he knew that his life as well as those of the two men in the adjoining room depended upon the force and skill with which he might handle the grave crisis which confronted them. He had seen and talked with most of the creatures when from time to time they had been brought singly into the workshop that their creator might mitigate the wrong he had done by training the poor minds with which he had endowed them to reason intelligently. A few were hopeless imbeciles, unable to comprehend more than the rudimentary requirements of filling their bellies when food was placed before them; yet even these were endowed with superhuman strength; and when aroused battled the more fiercely for the very reason of their brainlessness. Others, like Number Twelve, were of a higher order of intelligence. They spoke English, and, after a fashion, reasoned in a crude sort of way. These were by far the most dangerous, for as the power of comparison is the fundamental principle of reasoning, so they were able to compare their lot with that of the few other men they had seen, and with the help of von Horn to partially appreciate the horrible wrong that had been done them. Von Horn, too, had let them know the identity of their creator, and thus implanted in their malformed brains the insidious poison of revenge. Envy and jealousy were there as well, and hatred of all beings other than themselves. They envied the ease and comparative beauty of the old professor and his assistant, and hated the latter for the cruelty of the bull whip and the constant menace of the ever ready revolver; and so as they were to them the representatives of the great human world of which they could never be a part, their envy and jealousy and hatred of these men embraced the entire race which they represented. It was such that Number Thirteen faced as he emerged from the professor’s apartment. “What do you want here?” he said, addressing Number Twelve, who stood a little in advance of the others. “We have come for Maxon,” growled the creature. “We have been penned up long enough. We want to be out here. We have come to kill Maxon and you and all who have made us what we are.” “Why do you wish to kill me?” asked the young man. “I am one of you. I was made in the same way that you were made.” Number Twelve opened his mismated eyes in astonishment. “Then you have already killed Maxon?” he asked. “No. He was wounded by a savage enemy. I have been helping to make him well again. He has wronged me as much as he has you. If I do not wish to kill him, why should you? He did not mean to wrong us. He thought that he was doing right. He is in trouble now and we should stay and protect him.” “He lies,” suddenly shouted another of the horde. “He is not one of us. Kill him! Kill him! Kill Maxon, too, and then we shall be as other men, for it is these men who keep us as we are.”
