This manual written by William Alfred Peffer is described as a "statement of facts and figures showing the origin, history, use, object, and effect of tariff legislation in the United States, together, with much statistical information useful in tariff discussions." This pamphlet contains a great deal of statistical information about the impact of the tariff in the U.S. Peffer and other populists believed that tariffs were hurting farmers and workers. Peffer served as a U. S. Senator from Kansas representing the Populist Party.
