"THE LATE MR. E. L. MANSERGH.

The news of the sudden death of Mr. Ernest Lawson Mansergh in a nursing home, on October 22, will be received with regret by a wide circle in the engineering profession. For many years a partner in the firm of Messrs. James Mansergh and Sons, civil engineers, 5, Victoria-street, London, S.W.1, Mr. Mansergh was a son of the late Mr. James Mansergh, F.R.S., president of the Institution of Civil Engineers in 1900-01, and was born on April 13, 1866. In October, 1884, he was articled to his father for three years, during which time he was engaged in the preparation of drawings, quantities, and reports connected with various sewerage, sewage-disposal, and other works. He also assisted the resident engineers on the Burton sewerage scheme and on the Stockton and Middlesbrough Waterworks. In October, 1887, he was given charge of the construction of a small water-supply works at Newport, Essex, and, in the following January, returned to his father’s office as assistant. He became engaged in the preparation of designs for the Worthing Pier extension, and the Stockton and Middlesbrough, Mountain Ash, and Bristol Waterworks, and also on work connected with the Lancaster Borough Extension Bill. The year beginning July, 1888, was spent as resident engineer on the Worthing Pier extension, the works including a new pier head, concert hall and a steamboat landing stage.

Mr. Mansergh went to Melbourne in September, 1889, to assist his father in the collection of data for a report to the Government of Victoria on the drainage and sewerage of Melbourne and its environs, the district involved having an area of 133 sq. miles. On his return, in the following year, he became engaged, jointly with Mr. G. R. Strachan, in working out six alternative schemes and preparing detailed estimates for these. In the beginning of 1897 he entered into partnership with his father and assisted him in the preparation of numerous reports and the subsequent construction of works for water-supply, sewerage and other schemes. Prominent among these was the Elan Valley Water scheme of the Birmingham Corporation. This formed the subject of a masterly paper entitled “The Works for the Supply of Water to the City of Birmingham from Mid-Wales,” contributed jointly by Messrs. E. L. and W. L. Mansergh, to the proceedings of the Institution of Civil Engineers, on April 2, 1912. For their contribution the two brothers were awarded Telford Gold Medals, which were presented to them on November 5, 1912. Since the death of their father in 1905, Mr. E. L. Mansergh and his brother have continued to act as consulting engineers for many water-supply, sewerage, and other civil engineering undertakings and have been responsible for the construction of numerous works. Mr. E. L. Mansergh was a former student-member of the Institution of Civil Engineers, became an associate-member on May 5, 1891, and was transferred to the class of member on March 27, 1900."
