Best methods for combining, facilitating and harmonizing the transfer of freight between the waterway and the railway.; title: Communications: 1. Applications of reinforced concrete to hydraulic works. 2. Report on the works undertaken and measures adopted for the improvement and development of lines of inland navigation, as well as for the protection of the banks of navigable highways. 3. Utilization of the navigation of large but shallow rivers. Vessels and motors.; title: 2d section: Ocean navigation. Questions: 1. Means for docking and repairing vessels. 2. Dimensions to be given to maritime canals. (Technical point of view. Probable dimensions of the sea-going vessels of the future). 3. Mechanical equipment of ports.; title: Communications: 1. High powered dredges and means for removing rock under water. 2. Report on the most recent works constructed at the more important sea ports and especially on those relating to breakwaters. Applications of reinforced concrete; means for insuring its preservation. 3. Bridges and ferry bridges; tunnels under waterways used for ocean navigation. Economic and technical study. 4.
