He has been interested in the construction of more than ten miles in length of truss bridging, and in the construction of roofs of large buildings, covering more than fifteen acres of ground, most of which he designed and personally superintended their election. The last extensive structure that he designed, and the election of which he personally superintended, was the Union Passenger Depot, at Cleveland. He was the first person that designed and erected pivot draw-bridges of long spans, which, however, have been much increased in length of span by other parties since. He was also the first to design and erect a dome roof of a span of 150 feet, sufficient to cover three lengths of a locomotive with its tender, and numerous are the improvements he has introduced in the construction of railroad cars and locomotives. The only eight-wheeled dump gravel car in successful use was designed and put in practice by him. For a number of years Mr. Stone has been trustee of the First Presbyterian Church Society of Cleveland, and still holds that office. He was chairman of the building committee in the election of the new church edifice, and when it was burned down, was again elected chairman of the building committee, and given full charge of the reconstruction of the building. In 1868, Mr. Stone visited Europe, being compelled to seek relief, for a brief period, from the exhausting cares of his numerous business engagements. He is expected to return in the Fall of this year, ready to again engage in the active prosecution of the important enterprises with which he is connected, and in which he has won such distinction by his sound common sense, sound judgment, unresting energy, and practicable knowledge. In whatever he undertakes there is good reason for believing that the success he has hitherto met will still attend his efforts. Stillman Witt Connected indissolubly with the story of the rise and progress of the important railroad interests of Cleveland and northern Ohio, is the name of Stillman Witt. As one of the builders of the pioneer railroad from the city, and of the next in point of time, which has since become one of the foremost lines of the country in importance and profitableness, Mr. Witt deserves honorable record among the men who have contributed most to make Cleveland what it is to-day, a rich, populous, and rapidly growing city. Stillman Witt is a self-made man, and unlike some of this class, his self-manufacture will stand the test of close criticism. The material has not been spoiled or warped in the process. Those who know him best know that the struggles of his early years have not soured his disposition or hardened his feelings, and that access of fortune has not made him purse-proud. The Stillman Witt of to-day, rich and influential, is the same Stillman Witt who paddled a ferry boat at about forty cents a day, and was happy in his good fortune.
