ПЕРЕВОД ТЕКСТА НУЖЕН

When Martin Eden returned to San Francisco, he began to write. He sent his works to newspapers and magazines, but the editors sent his manuscripts back. Martine continued to write and study at the same time. Martine slept five hours: only a man in very good health could work for nineteen hours a day.

The weeks passed. All Martin’s money was spent and publishers continued to send his manuscripts back. Martin sold his coat, then his watch.

One morning the postman brought him a short thin envelope. There was no manuscript in that envelope, therefore, Martin thought they had taken the story. It was The Ring of the Bells. In the letter the editor of a San Francisco magazine said that the story was good. They would pay the author five dollars for it. And he would receive the check when the story was published.

Martin thought that five dollars for five thousand words was very little. After a few weeks the story was published, but the check didn’t` arrive. Martin had waited for about a month before he decided to go and get the five dollars from the editor.

He entered the office and said that he wanted to see Mr Ford – the editor. “I`m Martin Eden,” Martin began the conversation. He wanted to ask for his five dollars, but it was his first editor and he didn’t` t want to make a bad impression on him. To his surprise Mr Ford quickly stood up with the words “You don` t say so!” and the next moment, with both hands was shaking Martin`s hand.
