GROUP XXVI. 41 15. J. A. A. Waldorp, Chief Engineer of the Hydraulic Department, The Hague, Netherlands. DESIGNS FOR WATER SUPPLY AT THE HAGUE. Report.—Commended as one of the best examples in Europe of a well-conceived and well-executed system of water supply. The water is taken from the downs or sand hills near the coast; it is collected in canals, passed through filters of sand and shells, and then pumped to a wrought-iron reservoir holding one thousand cubic meters and standing about thirty-five meters above the level of the city. 16. Joh. Jacob Rieter & Co., Winterthur, Germany. TURBINES WITH ACCESSORIES AND WIRE ROPE FOR TRANSMITTING POWER—DESCRIPTION, PLANS, AND PHOTOGRAPHS. Report.—Commended for its very remarkable illustration of the successful transmission of enormous power from a single water-course to many different factories lying at a dis tance from it and in different directions. In one instance the power is transmitted through a tunnel. The most important of those shown is that at Bellegarde, where considerable engineering difficulties had to be overcome before the turbine houses could be even commenced. The power is transmitted to a distance of more than nine hundred and sixty-six meters. Double grooved rope pulleys are used for carrying power to intermediate stations. Further improve ments were made in the wire rope gearing by special apparatus for putting the wire ropes in place; special blocks and machines are used for stretching the same to avoid the draw back of differences in tension of different ropes. There are arrangements to stop the tur bines automatically in case of the breaking of a rope. The works are made under the general management of Mr. D. H. Ziegler, engineer. 17. J. B. & J. M. Cornell, New York, N. Y., U. S. IRON WORK FOR BUILDINGS. Report.—Commended for general excellence of workmanship, and ability for execution. 18. Garry Iron Roofing Co., Cleveland, Ohio, U. S. IRON ROOFING. Report.—Commended for improvement in securing metal roofing by a system of anchors, avoiding all nailing or screwing of joints, and allowing for the contraction and expansion of the metal. 19. James L. Jackson, New York, N. Y., U. S. IMPROVEMENT IN THE CONSTRUCTION OF STABLES AND FIXTURES. Report.—Commended for general plan of construction, appropriate proportions, strength, utility, drainage, and superior workmanship. 20. Rafael Guastavino, Barcelona, Spain. PLAN FOR IMPROVING THE HEALTHFULNESS OF INDUSTRIAL TOWNS. Repo7't.—Commended for the great number of plans of economical houses for working men and others.
