The captain came to see him and was very pleased to have a patient to look after. He told the man to rest for a few days and made the other sailors do his work. Three days later another sailor pretended that he had something wrong with his chest. Once more the captain looked in his medical books and told “sick” man to have a rest. The other sailors were very angry because they had more work to do. The patients had the best food and laughed at their friends when the captain was not looking. At last the mate (船长副手) decided to cure the “sick” men. He mixed up some soap, soot (烟灰), glue (胶水) and other unpleasant things. Then he obtained permission from the captain to give his medicine to the “sick” men. When they tasted the medicine, they really did feel ill. It was so horrible that one of the patients jumped out of hi bunk, ran up on desk and climbed the highest mast on the ship. He did not want any more medicine. The mate told both of the men that they must take the medicine every half an hour, night and day. This soon cured them. They both said they felt better and wanted to start word again.
