in Bordentown, New Jersey. Toward the end of its life in revenue service, the locomotive worked as a pump engine and as the power for a sawmill. The C&A was soon absorbed into the United New Jersey Railroad and Canal Company (1869), which, in turn, was merged into the Pennsylvania Railroad (PRR) in 1871. The PRR saw the potential publicity to be gained by exhibiting such an old engine, showing it at the 1876 Centennial Exposition in Philadelphia; PRR workshop staff then retrofitted the engine to look more as it originally had. The wide funnel was replaced with a straight metal tube and the cab walls and roof were removed. The PRR then exhibited the engine in 1883 at the National Railway Appliance Exhibition in Chicago, Illinois. In 1885, the Smithsonian Institution accepted the donation of the John Bull from the PRR as the Institution's first large engineering artifact. Smithsonian Institution and locomotive restoration At the exhibition in 1883, the Pennsylvania Railroad ended up resolving two problems at once. In the Smithsonian Institution, the railroad was able to find a home for the historic locomotive, as well as a suitable new employer for a young civil engineer named J. Elfreth Watkins. Watkins had been involved in an accident on the railroad in New Jersey a few years before the exhibition. He had lost a leg in the accident, so he was no longer suited to the physical demands of railroad work, although the railroad did employ him as a clerk for a while after his accident. The PRR employed his engineering experience as an expert curator for the Smithsonian's new Arts and Industries Building, which was opened in 1880. The locomotive's first public exhibition at the Smithsonian occurred on December 22, 1884, where it was displayed in the East Hall of the Arts and Industries building. The locomotive remained on display in this location for nearly 80 years, but it was transported for display outside the museum on certain rare occasions. The most significant display in this time occurred in 1893 when the locomotive traveled to Chicago for the World's Columbian Exposition. The Pennsylvania Railroad, like many other railroads of the time, put on grand displays of their progress; the PRR arranged for the locomotive and a couple of coaches to be delivered to the railroad's Jersey City, New Jersey, workshops where it would undergo a partial restoration to operating
