29 before the flood has actually arrived, i. e. as soon as the front part of the approaching flood begins to increase the local slope. In addition, the writer cites examples in connection with the proposed canalisation of the Triple-Körös, showing the application of this method. III. DATA FROM THE FIRST FOUR YEARS OF THE REORGANIZED STATISTICS ON THE TRAFFIC OF WATERWAYS. By J. VÁRSZEGHY. (Pages 429—460.) Statistical data on the traffic of waterways in Hungary have been gathered ever since 1888. The Treaty of Trianon internationalized the most important waterways of Hungary, thus necessitating a thorough transformation and extension of the former statistical work. The collection of data on the new system started in the beginning of 1931. The five groups of the traffic on waterways are treated of separately, as follows : 1. Traffic of River Harbours. Most of the traffic in the harbours of the Danube and Tisza is carried on by four cooperating navigation companies (the Hungarian River and Sea Navigation Company, First Danube Steamship Navigation Company, Bavarian Lloyd Nav. Сотр., and South-German Danube Nav. Сотр.). These companies were the first to be required to report data of their traffic. In 1934 the obligation to report was extended to four other domestic companies and five foreign ones, so that since that year our collection of data may be considered as quite complete. In order that the traffic of different years can be compared, the tables of this article contain only data of the four years mentioned above. (Table I. Goods traffic in the harbours, a) Danube harbours, b) Tisza harbours. Column 1 : Total quantity of goods registered and delivered, in quintals ; Column 2 : Goods of the total traffic arriving from and sent abroad, in quintals.) In the years 1931—34 the traffic of the Danube harbours amounted to 10—12 million quintals, about 50% of which fell to the Budapest harbours. The traffic of the Tisza harbours shows a great variation, owing to the varying amount of crops (0-8—2-2 million quintals). Coal form the principal part of the goods carried on waterways. (Table II. Page 435. Kinds of goods in the traffic of harbours. Column 1 : Total quantity of goods registered and delivered. Column 2 : Goods arriving from and sent abroad.) The proportional number of the coal varies between 34-0 and 45-2% (item 9), and that of the cereals (item 1) 14-7—30-4%, the latter taking the second place in succession every year. Commodities carried in considerable quantities are : Salt (item 4), Forestry products (item C), Milling products (item 2), and Mineral oil products (item 10). Other items : 3. Legumina and grains, 5. Provisions, 7. Raw materials of vegetable origin, 8. Building materials, 11. Products of the iron and other metal industry, 12. Manufactured articles, 13. Other goods.
