The third had" one grand arch over the river and several small arches over the low ground; estimated cost, $745,800. (Fig. 9, Plate 1). VII. M. G. Eiffel, of Paris, forwarded two projects. The first comprised arched spans carrying the roadway above, the estimate for which was $534,468, or $529,540--the latter price was substituted in case bricks could be used above high water mark instead of cut stone. (Figure 1, elevation and plan, Plate 1). The second comprised a grand parabolic lattice arch of 459.2 ft. span across the river with the roadway suspended from the arch; the viaduct was continued over the low ground by smaller spans of continuous arched lattico trusses, with the roadway above. The cost of this project was $501,800. VIII. M. T. Seyrig, of Paris, presented two schemes. The first comprised three grand openings with lattice arches, the roadway traversing the arches supported by them; cost, $492,294. (Figure 15, Plate 2.) The second design crossed the river by a lattice arch intersected by the roadway suspended from it; this was continued over the low. ground by a series of small arched openings. (Figure 14, Plate 2). The cost varied between $441,760 and $376,640, according to whether all the foundations were put in by compressed air, or only the abutment and first pier on the Szegedin side. IX. Messrs. Knestlin, Wegerer and Wellspacher, of Vienna, offered a design in which the river was spanned by a grand arch and the bridge continued over the low ground by a continuous girder. Cost, $571,120. (Figure 18, Plate 2). X. M. Van der Made, of Amsterdam, sent a project having parabolic latticed arches, the estimated cost of which was $540,760. (Figure 19, Plate 2. XI. Messrs. Galopin, more
