This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form.

Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

William Milnor Roberts was a civil engineer, who's greatest engineering feats at this time was the construction at Harrisburg in 1837 of a two-level lattice-truss bridge across the Susquehanna River, carrying a double-track railroad above and a double carriage-way and footpaths below.
Roberts was vice-president. (1873 - 78) and president (1878) of the American Society of Civil Engineers.
Background
William Milnor Roberts was born on 12. 02. 1810 in Philadelphia, Pennsylvania, United States. He was a son of Thomas Pascal and Mary Louise (Baker) Roberts. He was of Welsh Quaker descent, his family having come to America with William Penn.
Education
Roberts was educated in a Friends' school in Philadelphia, then took a special course in mathematics for two terms, after which he studied architectural drafting under John Haviland. Completing his education at the age of fifteen, he joined the engineering corps under Sylvester Welch which was engaged in the construction of the Union Canal of Pennsylvania from the Schuylkill at Reading to the Susquehanna a little below Harrisburg.
Career
In 1826 he was a rodman in the preliminary survey for the construction of a macadam road across the Alleghany Mountains in Pennsylvania to connect the canal system on the eastern with that on the western slope, and in the following year he began work as an assistant in the survey and construction of the Lehigh Canal between Mauch Chunk and Philadelphia. He helped in the improvement of the inclined planes at Mauch Chunk and took part in the construction and operation of the coal railroad connected therewith. Four years later, in 1831, he was appointed senior assistant engineer under Welch for the survey of the proposed Allegheny Portage Railroad. William Milnor Roberts was in charge of the location of the eastern part of the line, from the headwaters of the Conemaugh over the summit and down to Hollidaysburg, and subsequently superintended the construction of eight of the ten inclined planes. Upon the completion of this work in 1834 he served as general manager of the road until January 1835, when he became chief engineer of the Lancaster & Harrisburg Railroad. Roberts was now only twenty-five years old, but he had had ten years' experience in canal and railway transportation, possessed much mechanical ability, and had developed a special aptitude for design. He remained with the Lancaster & Harrisburg from 1835 to 1837, assuming, in addition, the position of chief engineer of the Cumberland Valley, and completed the construction of both roads. One of his greatest engineering feats at this time was the construction at Harrisburg in 1837 of a two-level lattice-truss bridge across the Susquehanna River, carrying a double-track railroad above and a double carriage-way and footpaths below. Continuing in the capacity of consulting engineer for the railroads, he was given charge, 1838-40, of the extensions of the Pennsylvania state canals, particularly in the western part of the state. For the next eight years he was engaged chiefly in canal construction, enlarging the Welland Canal in Canada, directing the enlargement of the Erie Canal of Pennsylvania, and acting as chief engineer of the Sandy & Beaver Canal in Ohio. In 1849 he returned to railroad work, building the Bellefontaine & Indiana, the Allegheny Valley, the Atlantic & Mississippi, and the Iron Mountain railroads, and serving as chairman of a commission appointed by the legislature to consider the reconstruction of the Allegheny Portage Railroad. During this period the battle of railroad gauges was being waged, some railroads favoring a 6' and others a 4' 81/2" width. Roberts strongly advocated the latter gauge and succeeded in bringing about its adoption as the standard. In 1855-57 he was engaged in the construction of a number of Middle-Western railroads, and late in the latter year went to Brazil, where he obtained the contract to build the Dom Pedro Segundo Railroad. This difficult undertaking involved considerable tunneling and required eight years' time to complete. Roberts returned to the United States in 1866, was almost immediately appointed on the commission to propose improvements of the Mississippi River at Keokuk, Iowa, and was also made United States engineer in charge of the improvement of navigation of the Ohio River. Taking leave of absence in 1868 from this position, he served as associate chief engineer in the construction of the Eads Bridge across the Mississippi at St. Louis. Late in 1869 he was appointed chief engineer of the Northern Pacific Railroad and continued in that position for a decade, during which time he also served as a member of the Mississippi River Jetty Commission by appointment of President Grant. In 1879 he accepted the appointment of chief engineer of all public works in Brazil, and for the remaining two and a half years of his life was occupied with the examination of rivers, harbors, and waterworks there. Roberts was vice-president. (1873 - 78) and president (1878) of the American Society of Civil Engineers. His writings, published principally in its Transactions, were usually descriptions of actual observations and expressions of opinion as to the application of experience to new engineering problems. He rarely developed mathematical theories, for he was opposed to the too free use of theoretical formulae.

Connections
He was married twice: in June 1837 to Annie Gibson of Pennsylvania, who died in 1857; and in November 1868 to Adeline Beelen of Pittsburgh, who with three children and six children of his first wife survived him.
