"I shall have trouble with this tooth," thought Tushmaker, but he clapped on his heaviest forceps and pulled. It didn't come. Then he tried the turn-screw, exerting his utmost strength, but the tooth wouldn't stir. "Go away from here," said Tushmaker to Byles, "and return in a week, and I'll draw that tooth for you or know the reason why." Byles got up, clapped a handkerchief to his jaw, and put forth. Then the dentist went to work, and in three days he invented an instrument which he was confident would pull anything. It was a combination of the lever, pulley, wheel and axle, inclined plane, wedge and screw. The castings were made, and the machine put up in the office, over an iron chair rendered perfectly stationary by iron rods going down into the foundations of the granite building. In a week old Byles returned; he was clamped into the iron chair, the forceps connected with the machine attached firmly to the tooth, and Tushmaker, stationing himself in the rear, took hold of a lever four feet in length. He turned it slightly. Old Byles gave a groan and lifted his right leg. Another turn, another groan, and up went the leg again. "What do you raise your leg for?" asked the Doctor. "I can't help it," said the patient. "Well," rejoined Tushmaker, "that tooth is bound to come out now." He turned the lever clear round with a sudden jerk, and snapped old Byles's head clean and clear from his shoulders, leaving a space of four inches between the severed parts! They had a _post-mortem_ examination--the roots of the tooth were found extending down the right side, through the right leg, and turning up in two prongs under the sole of the right foot! "No wonder," said Tushmaker, "he raised his right leg." The jury thought so, too, but they found the roots much decayed; and five surgeons swearing that mortification would have ensued in a few months, Tushmaker was cleared on a verdict of "justifiable homicide." He was a little shy of that instrument for some time afterward; but one day an old lady, feeble and flaccid, came in to have a tooth drawn, and thinking it would come out very easy, Tushmaker concluded, just by way of variety, to try the machine. He did so, and at the first turn drew the old lady's skeleton completely and entirely from her body, leaving her a mass of quivering jelly in her chair! Tushmaker took her home in a pillow-case.
