When the constructionof the fireworkfactory came to the stage of painting, a pumpwas put in. Then, all the painters in the neighbourhoodwere defeated by a severedisease whose characteristicwas aliketo that of a bad burn.
An expertphysicianwas instructed to attendto the victims and handlethis case. He was enthusiastic, but he didn’t foreseethat it was a hard challenge. After simple enquiry, he announced that the polluted paint was to blame. But without positiveevidence, people suspected and rejected his view, saying the theory he put forwardmade no sense. Being much more strictwithhimself, he contributed himself to the case. Apart frommaking enquiries, he made detailed charts and analysed the data cautiously. Finally, he drew a scientific conclusion, linking the disease tothe radiumin the pump. Exposedtoradium, a kind of radioactive material in the universe, people absorbed radiation and got sick immediately.
Spinning the pump backward, he took away the radium. This simple movementcured all the victims.
