Richter now began to work harder than ever. His books of extracts were invaluable, as were his hand-books of comical matters, touching incidents, synonyms, etc. He made it a rule to write half a day, and take long walks in the afternoon in the open air, thinking out the plans for his books. Poor as he was, he was always cheerful, sustaining by his letters any who were downhearted. One of his best friends, Herman, who had become a physician through much struggle, died about this time, broken on the wheel of poverty. Despite his own starving condition, Paul sent him five dollars. Having an opportunity to teach French to the brother of a Leipzig friend, he accepted; but at the end of three years, through the disappointing character of the pupil, and the miserliness of the father, Paul returned to his mother, broken in health and dispirited. His heart ached for those who like himself were suffering, and now he made a resolution that changed for life the course of his writing. He would write satire no more. He said, "I will not pour into the cup of humanity a single drop of gall." Henceforward love, and hope, and tenderness, breathe upon his every page. He now wrote ten essays on "What is Death?" asking the noble-hearted Herder to send them to Weiland for his magazine, lest they be overlooked in his mass of papers, if Richter, unaided, should venture to ask the favor. They were overlooked for months; but finally Herder procured the insertion of one essay in a different magazine, but Richter never received any pay for it. Three years had passed, and all this time the third volume of the "Greenland Lawsuits" had been journeying from one publishing house to another. At last it was accepted, but little money came from it. Again he taught,--this time at Schwarzenbach, where he used to go to school. Here his tenderness, his tact, and good cheer won the hearts of the pupils. There was no memorizing of Latin dictionaries, but the exact work of all was kept in a "red book" for parents to see. He instructed them orally five hours a day, till they were eager for astronomy, history, and biography. For four years he taught, "his schoolroom being his Paradise," every Sunday walking to Hof to see his mother. Well might he say, "To the man who has had a mother all women are sacred for her sake."
