PERSONAL. John M. Diven, superintendent of waterworks at Elmira, N. Y., and secretary of The American Water Works association, has been appointed to a similar position in charge of the Charleston. S. C, plant, of which he will take control on February 10. Mr. Diven has been connected with the Elmira works for thirty-one years, and has succeeded in keeping them up to the highest standard of efficiency. His leaving the city where he has lived so long and is so favorably known is greatly regretted by a large circle of friends and acquaintances and the officers of the waterworks, with whom he worked in harmony for So many years. Mr. Diven makes the change for a betterment of his financial condition, and there is no doubt that the Charleston authorities have made a very judicious selection.
