But the occupants of Larry's smaller cage were friendly. They were a man and a girl of 2930 A.D.! The girl was the Princess Tina, and the man, Harl, a young scientist of that age. With an older scientist--a cripple named Tugh--Harl had invented the Time-vehicles. * * * * * We had heard of Tugh before. Mary Atwood had known him in the year 1777. He had made love to her, and when repulsed had threatened vengeance against her father. And in 1932, a cripple named Tugh had gotten into trouble with the police and had vowed some strange weird vengeance against the city officials and the city itself. More than that, the very house on Patton Place from which we had rescued Mary Atwood, was owned by this man named Tugh, who was wanted by the police but could not be found! Tugh's vengeance was presently demonstrated, for in June, 1935, a horde of Robots appeared. With flashing swords and red and violet light beams the mechanical men spread about the city massacring the people; they brought midsummer snow with their frigid red rays; and then, in a moment, torrid heat and boiling rain. Three days and nights of terror ensued; then the Robots silently withdrew into the house on Patton Place and vanished. The New York City of 1935 lay wrecked; the vengeance of Tugh against it was complete. Larry, going back in Time now, was told by Harl and Princess Tina that a Robot named Migul--a mechanism almost human from the Time-world of 2930--had stolen the larger cage and was running amuck through Time. The strange world of 2930 was described to Larry--a world in which nearly-human mechanisms did all the work. These Robots, diabolically developed, were upon the verge of revolt. The world of machinery was ready to assail its human masters! Migul was an insubordinate Robot, and Harl and Tina were chasing it. They whirled Larry back into Time, and they saw the larger cage stop at a night in the year 1777--the same night from which Mary Atwood had been stolen. They stopped there. Harl remained in the little cage to guard it, while Tina and Larry went outside. It was night, and the house of Major Atwood was nearby. British redcoats had come to capture the colonial officer; but all they found was his murdered body lying in the garden. Migul the Robot had chained Mary and me to the door of his cage; had briefly stopped in the garden and killed the major, and then had departed with us. * * * * * We now went back to the Beginning of Time, for the other cage was again chasing us. Reaching the Beginning, we swept forward, and the whole vast panorama of the events of Time passed in review before us. Suddenly we found that Tugh himself was hiding in our cage! We had not known it, nor had Migul, our Robot captor. Tugh was hiding here, not trusting Migul to carry out his orders!
