PERPETUAL MOTION.
Reading edition
Tommy was only ten years of age, but still he was determined to obtain it. At last, one day, he ran into his father's office in ecstasies, and shouted, "Hurrah! Pop, I've got it!"
"Got what, my son?"
"Perpetual motion!" cried Tommy. "I've been watching it for the last half hour, and it works bully!" Then grasping "Pop" by the hand, "Come up in the garret and see it."
His father went up, and, sure enough, there was perpetual motion—that is, as long as there was any life left in the dog and that piece of roast beef hung to his tail.
