Remarkable and historically valuable collection of a surveyor's field books covering nearly fifty years in the Gold Country of California, with surveys for an astonishing range of projects, from mines and water systems to golf courses and airfields, plus highways, orchards, railroads, regular roads, farms, and more, even an Odd Fellows Hall. At the beginning of most of the volumes is an index to the surveys, and other indication of contents (one says "City Work Only." In addition, O'Connor, whose surveyor's license was No. 976,.tracks his hours, "shoots" the sun, outlines classes in surveying, etc. Much of his work was done in the employ of the firm of T.H. McGuire of Grass Valley (for whom he worked in the 1930s and 1940s), though he did work for others including the Donner Lake Co. Four of the field books in the collection belonged to T.H. McGuire's son, Carlos. Lot Amendments Condition: Normal wear that can be readily associated with such books used in the fields, but overally in very good condition, better than one might expect.
