Prisoners spent forty-eight hours a week working in the fields, quarry, adobe yard, or in prison shops, and anything they could not make themselves or barter for they had to do without. The prison had two shop buildings, one in the east yard and one on the site in front, and together they housed several different workshops that produced needed goods ranging from garments from the tailor and shoe shop to breads and desserts from a bakery oven, as well as items such as tin cups, mattresses, silver spurs, and carved wooden table legs. Rehabilitation at that time consisted of more knowledgeable inmates teaching those who wanted to learn, and after hours inmates could make crafts to sell or trade at a monthly public craft fair, with part of the profit saved and given to them when they left the prison. The museum to the left was not one of the prison buildings; it was built in 1939 on the original foundation of the mess hall to preserve the historic site, using volunteer labor and locally raised and Federal funds, and it was completed in a record sixty days.
