THE SCHNEIDER PAVILION AT THE PARIS EXHIBITION. part, 5 ft. 8.9 in. To cast this ingot five Siemens-Martin furnaces of 16, 30, 35, 40, tons were employed. Fig. 1101 shows another example of cast and forged steel ; the pieces shown form parts of a press used in Messrs. Schneider and Co.’s Works, to compress liquid steel. Tliey were formed out of ingots having about 50 in. diameter, and weighing, one 55 and the otlier 36.5 tons. They were finished by forging on a mandril. charts, equal to (17 + 7.85) = 24.85 metres (81 ft 6 in.) below the average high-water spring tides. Principal dimensions of caisson : No. 1.—63 x 35.50 (206 ft. 6 in. x 117 ft. 6 in.) ; weight, 730 tons. No. 2.—10.50 x 24.30, average (34 ft. 6 in x 80 ft. average) ; weight, 90 tons. No. 3.—10.50 x 11.80 (34 ft. 6 in. x 38 ft. 6 in.) ; weight, 50 tons. (6) The otlier set of caissons will be sunk to a depth Fig. 1101. Steel Torgings for 10,000-Ton Hydraulic Press, Creusot. IMPROVEMENT OF HAVRE HARBOUR WORKS. Head Works of the Wet-Dock Sluices. This sluice forms part of a general programme for improving the conditions of Havre Harbour; it will transform the Eure and Bellot basins into full-tide wet docks ; they can now only act as half-tide docks. The construction was given in 1899 to Messrs. Vigner and Schneider and Co., who tendered for it jointly. The two head works will rest on iron caissons sunk by compressée! air ; each contains a main caisson, to which are fitted two other caissons of less importance, for estab- lishing a junetion with the adjoining quay walls. (a) The caissons of the one head will be sunk to a depth of-17 metres (55 ft. 9 in.) below 0 of Havre naval of— 9.50 metres (31 ft.), the No. 1 caisson, and of— 7 metres (23 ft.) those of Nos. 2 and 3. Principal dimensions of caisson : No. 1.—65.10 x 32 (213 ft. 6 in. x 105 ft.) ; weight, 700 tons. No. 2.—17.50 x 23 (57 ft. 6 in. x 75 ft. 6 in.) ; weight, 135 tons. No. 3.-1.70x38, average (5 ft. 6 in. x 124 ft. 6 in., average); weight, 210 tons. The total measurement of the masonry is 85,000 cubic metres (3,000,000 cubic ft). The work is now in progress. The designs, processes to be followed in sinking the caissons, calculations of stability of résistance of the varions parts under various conditions to be encountered, &c., were carried out jointly by Messrs. Vigner and Schneider and Co. The working designs of the construc- tion of the caissons were completed by Messrs. Schneider and Co. at their Chalon yard.
