"Milling in the Joplin District is, compared with the practice in other zinc fields, seemingly very crude. To one unacquainted with the peculiar conditions of this district, the amount of ore which goes into the tailing pile seems unnecessarily high. There are several things which account for the low saving made" – p. [1].
