Patent Iron Suspension Railroad Bridge. The undersigned would inform the officers of Railroads and others, that he is prepared to furnish Drawings and Estimates for Bridges, Roofs, etc., on the plan of Bollman’s Patent. The performance of these bridges, some of which have been in use for six years, has given entire satisfaction. Their simplicity of construction renders repairs easy and cheap, and by a peculiar connection of the Main and Panel Rods at the bottom of the Posts, all danger from the effects of expansion, which has heretofore been the chief objection to Iron Bridges, is entirely removed. J. H. TEGMEYER, Baltimore, Md. - Plan of Harpers Ferry Bridge
Shortly after the Harpers Ferry bridge reconstruction, Bollman was made foreman of bridges. It is apparent that, on the basis of his practical ability, enhanced by the theoretical knowledge gained by intense self-study, he eventually came to assist Chief Engineer Benjamin H. Latrobe in bridge design. He later took this work over entirely as Latrobe’s attentions and talents were demanded in the location and extension of the line between Cumberland and Wheeling. - Duryea Automobile
Description of first trip in the car When I got this car ready to run one night, I took it out and I had a young fellow with me; I thought I might need him to help push in case the car didn't work…. We ran from the area of the shop where it was built down on Taylor Street. We started out and ran up Worthington Street hill, on top of what you might call "the Bluff" in Springfield. Then we drove along over level roads from there to the home of Mr. Markham , and there we refilled this tank with water. [At this point he was asked if it was pretty well emptied by then.] Yes, I said in my account of it that when we got up there the water was boiling furiously. Well, no doubt it was. We refilled it and then we turned it back and drove down along the Central Street hill and along Maple, crossed into State Street, dropped down to Dwight, went west along Dwight to the vicinity where we had a shed that we could put the car in for the night. During that trip we had run, I think, just about six miles, maybe a little bit more. That was the first trip with this vehicle. It was the first trip of anything more than a few hundred yards that the car had ever made. - Dredges at work in the Suez Canal

It can be readily seen that this drawing was not made after the plan of the first vehicle. - J. Frank Duryea, about 1894
Of the numerous American automotive pioneers, perhaps among the best known are Charles and Frank Duryea. Beginning their work of automobile building in Springfield, Massachusetts, and after much rebuilding, they constructed their first successful vehicle in 1892 and 1893. - Drawing of 1885 Benz engine
