[2], viii, [5]-335 pp. With large color lithographed map loose in rear pocket; 1 folding wood-engraved map showing locations of veins and mining in California; 2 folding tables; 13 plates of plans & details of various ditches, some folding or double-page; woodcuts in the text. (8vo) 22.4x14 cm (8¾x5½"), original cloth, front cover lettered in gilt. First Edition.

Scarce report with much of note, none more so that the large folding color map, "Map of Georgetown Divide, El Dorado County showing also Portions of the Placerville and Forest Hill Divide with the Ditches, Mines and other Properties of the California Water Company" (53x127 cm), which is apparently the first map of El Dorado County, and in itself quite scarce. The map has a wealth of information on it and is visually striking by its use of color to represent terrain. It is quite clean and very attractive.
