Й0 flat-slab floors and the girdered ceilings of the machine house (figs. 7—17 and photos 1—12). In constructing the building 19.640 cu. metres of concrete, and 1940 tons of iron reinforcement were employed. There are 25.000 sq. metres of flat-slab floor. The cost of the building amounted to round 3,211.000 pengő, that of the mechanical equipment to 1,534.000 pengő, total 4,745.000 pengő. The granary was built by the Budapest Dutyfree Harbour Co. Ltd ; the design and construction were controlled by a State Commissioner's Office. The structures of reinforced concrete were carried out by the firm of Pittel and Brausewetter (Budapest), the mechanical equipment was designed by the firm of Amine and Luther (Brunswick) and supplied for the most part by the Ganz and Co.

— Danubius Works Ltd, Budapest. With regard to the construction, it may be mentioned that flat-slab floors were employed to a great extent, soft concrete was used for the reinforced concrete structures, and the cells of the silo, above the lower cylindrical part, were built with the aid of sliding moulds (photo 29). The granary was put into operation seven years ago, and ever since its business has constantly been increasing, so that several reconstructions and alterations have had to be made. Thus, among others, the transformation of the movable suction-elevator rendered it possible to load corn through an automatic balance not only into, but also out of the granary either to barge or wagon. Three balances have been set up below the platforms, the number of boxes has been increased, the loading bridge transformed into a crane, etc. Devices have been installed for cleaning and sorting legumina, for destroying corn weevil, and for separating barley from tares. The tables at the end of the article give information as to the business (fig. 18) and income of the harbour and the granary (1. traffic of the harbour, 2. business of the granary, 3. financial results). In table 3 the share of the granary is about 30 percent. II. REGULATION OF THE WATER LEVEL OF LAKE BALATON AND THE SLUICE AT SIÓFOK. By J. BERTÓK. (Pages 582—621.) Lake Balaton with a catchment area of 5187 sq. kilometres, is 77 Km long, and 8 Km wide on an average, but only 3 to 4 metres deep. Its main tributary is the Zala, and it is drained by the Sió (fig. 1). Formerly, at high stages, about 17,000 hectares of its flat shores were inundated The drainage of the marshes along Balaton, the lake navigation, and the development of resorts were rendered possible by constructing the sluice at Siófok and by improving the channel of the Sió. The first design for the latter was made by J. Beszédes about 1820. First., four dams serving the supply of water mills were removed ; then, as the down-flow conditions were not secured by this to the desired extent, a sluice with a discharge of 17—18 cu. metres was constructed in 1863, but the result attained was not satis-
