About the Book
Charles Peters, born in Portugal in 1825, first visited California in 1846 as a merchant seaman, returning three years later to seek gold at Columbia, Jackson Creek, and Mokelumne Hill. The autobiography of Charles Peters (n.d., ca. 1915) is the old man's brief memoir of his life through the 1850s, followed by a series of "Good Luck" stories, miscellaneous tales of the mining camps, a few of which seem to be credited to Peters although most are the work of another author, drawn from many sources.
