The lady ultimately chose Stevenson, divorced Osbourne, and in May 1880 she and Stevenson were married in San Francisco. A few days later, the couple left for a honeymoon in the Napa Valley, where Stevenson produced his work "Silverado Squatters". He later wrote "The Amateur Emigrant" in two parts about his passage to America: "From the Clyde to Sandy Hook" and "Across the Plains". His middle-class friends were shocked by his travel with the lower classes; it was not published in full in his lifetime, and his father bought up most copies.
