In 1904, Warren commissioned Upton Sinclair to write a novel about immigrant workers in the Chicago meat-packing houses. Wayland provided Sinclair with a $500 advance and after seven weeks' research, he wrote the novel, "The Jungle". Serialized in 1905, the book helped to increase circulation of the newspaper to 175,000. After the book was published by Doubleday in 1906, the popularity of the "Appeal to Reason" increased, as did the attacks on Wayland and Warren. The phenomenal success of Wayland's newspaper meant that he developed a printing plant capable of handling a weekly newspaper of huge circulation; on occasion more than 400,000 copies per week were printed. The Appeal to Reason Company issued hundreds of other socialist publications in addition to the Appeal, making the Girard, Kansas name known.
