In the Holman and Merriman Machine Shop opposite this location, George A. Long of Northfield, Massachusetts, built a steam-propelled four-wheel automobile in 1875 with a fifth wheel for steering. Fired by hardwood charcoal, the vehicle had a bicycle-type frame, ordinary wooden wheels, a solid rear axle, and could maintain 30 miles per hour when roads permitted. This early inventor later patented and built another automobile propelled by gasoline, now in the Smithsonian Institution.
