The disabled railroad signalman named James Edwin Way was passing through a lively market in South Africa and saw a baboon herding an ox cart that he had never seen before, and he was so shocked that he did not hesitate to buy the baboon and named it Jack, and the baboon became his pet and personal assistant.
The railroad worker accidentally lost both legs a few years later, and he had to go to the station every day, and it was difficult to have more than 800 meters of distance, so he began to train the baboon, at first to let it push itself to work with a trolley, and then help himself to clean, take out the garbage and do housework, and every time the train changed tracks, it was judged according to the number of honks, and this matter was also handed over to Jack, and it was never at fault.
But the baboon's work was seen by the passengers, so the passengers complained to the railway bureau, which decided to test the baboon's adaptability to respond to the complaint, in the test it could accurately change the track according to the number of honks, and from then on the official gave it a hiring number, and it officially became a railway signalman, paid 20 cents a day, half a bottle of beer a week, until he died of tuberculosis in 1890.
