A 1913 economics article analyzing how the U.S. Tariff Board's report on Schedule K (wool and wool manufactures) related to the six competing wool tariff bills of the Sixty-second Congress. It explains why the Board did not recommend rates, then uses the Board's cost data to compare the La Follette, Underwood, Compromise, Penrose and Hill bills against the protection needed for raw wool, tops, worsted yarns and woolen and worsted fabrics. It contains many statistical tables of production and conversion costs and duties.
