Tyson, Philip T.:

$3,500 · Offered by William Reese Company

GEOLOGY AND INDUSTRIAL RESOURCES OF CALIFORNIA.... The second (and best) edition, following the government document edition of the previous year. An important discussion of the geology of gold in California, based on Tyson's four-month trip during the summer and early fall of 1849, including a fine map of the Sacramento Valley, a smaller one of the author's travel routes, and one of his path through the Sierra Nevada. Wheat notes that this was "probably the earliest work of a true scientific research to emerge from the Gold Rush." Tyson describes visits to Sacramento, Mormon Island, Coloma, Jackson, and the Cosumnes and Mokelumne Rivers. The Senate ordered 5,000 copies printed, of which 1,000 were for Tyson's use. Tyson added a new titlepage, an errata page, index, contents page, and an extensive introduction to this edition.
