Revenue of the United States. Official Report by ... D. A. W. ... Reprinted. [With a preface by the Cobden Club
Catalogued as an official United States revenue report reissued in 1874 by J. B. Ford & Co. with a Cobden Club preface, though the plates are those of a mining engineer's manual on ore dressing. The 80 figures are line-engraved plans, sections and elevations of buddles, stosshcerds and washing machinery, plus hatched cross-sections of ore veins, useful as measured technical linework and fine engraved shading.
