James Abram Garfield was elected as the 20th president of the United States on 1880. This versatile man is a major general and the first president to have the status of a priest. In addition, he is also a mathematician, who has done an excellent job in proving Pythagorean theorem. Garfield is also a very unfortunate president. Shortly after taking office, he was shot twice at close range by a disgruntled government worker at Washington Station on June 2188/KLOC-0. But more unfortunately, the limitation of medical conditions makes the president's rescue work more like today's medical accident.

For several weeks, famous doctors all over the country explored the president's wound with their own fingers or instruments, but all failed. Therefore, the helpless doctors turned to Bell, the inventor of the telephone, for help. Mr. Bell immediately designed an electronic instrument that will make a click when it is placed near any metal. Mr. Bell warned that when using the instrument, there should be no metal objects nearby. But when the doctors tried to probe with instruments, the dying president was lying on a bed with a metal frame and a metal spring.

Bell and several doctors heard the sound of instruments near the black and purple wound, and Bell concluded that the bullet should be deeper. At this time, the president's temperature has risen, so we can't hesitate any longer. The doctors decided to reopen the wound and dig deeper. But still no bullets were found. President Garfield, on September 188 1, 19, couldn't stand the infection caused by unclean exploration any longer, and died of high fever and exhaustion.

The autopsy results came out, and the bullet was wrapped in a capsule, like a silkworm baby that didn't break out of its cocoon, more than 20 centimeters away from the wound. Some medical experts later commented that if nothing was done and the bullets were left there quietly, maybe the president would survive. The device designed by Bell to rescue the president was later transformed into a mine detector.
