On page 278 of my article, “The Controversy Over Grain Conveyance During the Reign of Qubilai Qaqan, 1260–94,” which appeared in the May 1954 Number of the Far Eastern Quarterly (13.3), I translated Hsing Ch'uan Fu Ssu as the Ambulatory Office for Ch'uan-chou. It should be translated as the Ambulatory Money Bureau, inasmuch as it was a branch of the Ch'uan Fu Ssu or the Money Bureau which was in existence from 1281 to 1311. (Cf. Yang Lien-sheng, Money and Credit in China, [Cambridge: Harvard University Press, 1952], 97.)
