10 The longitudinal stiffening of the’ quay shall be arranged in the following way. A piece of 231/s by 23^2 cm timber shall be placed close to the piles resting on the nethermost ties and fastened to the main piles with one 25 mm bolt and to each tie-beam with one 22 mm bolt. Another piece of 231/-’ by 23^2 cm timber shall be placed immediately below the topmost ties and shall be notched into the piles and fastened to them with one 25 mm boll and to each tie with one 22 mm bolt. Two pieces of 231/a by 23^2 cm timber shall be placed over the inner ends of the nethermost ties, one on each side of the vertical timber, to which they shall be fastened with one 25 mm bolt transpiercing the three timbers. Another two pieces of 231/ä by 23^2 cm timber shall be placed under the inner ends of the topmost ties, fastened to the vertical timber in the same manner. Two pieces of 13 by 26 cm timber shall be placed resting on the nethermost ties; they shall be notched together with them and fastened with one 19 mm bolt to each tie. Pairs of diagonal braces of ll3/* by 231/z cm timber shall be placed both in the plane of the piles and the plane of the vertical timbers, as indicated on the drawing; the braces shall be fastened with bolts having a diameter of 22 mm. In the longitudinal plane there shall be placed eight 3P/2 cm stay-piles fastened to the main piles like the stay-piles in the plane of the supporting frame. The concrete-block shall have a base of 2 by 2 m, and a height of 2 m. But the sides shall recede upwards from the vertical line so as to give the top of the block a side ot l’/2 m. 1 he upper surface shall be given a slope to both sides. The supporting frames shall be anchored to the blocks by two 30 mm holding-down-bolts which are fastened at the foot by means of a key to a 130X50X5 cm foundation-plate of cast-iron, moulded in the block at a distance of 80 cm from the top. At the top each of the bolts is to be passed through a toggle of cast-steel 75 by 13 by 5 cm, by which the tim- bers resting on the two nethermost ties are to be held down. After the erection of the supporting frames the holes round the bolts must be carefully fdled with a thin composition of 1 cement -{- 1 sand. The uppermost 80 cm of the bolts as also the nuts shall be galvanized. The concrete for the blocks shall be composed of 1 cement 4- 2 sand -|- 4 shingles. The connection between the quay and the top of the mole shall be arranged in the following manner. At each supporting frame there is to be placed a horizontal piece of 231/a by 23x/2 cm timber, thrust in between the protruding ends of the topmost ties and fastened to them with one 25 mm bolt. The other end of this timber shall be clamped to a piece of 23l/2 by 23Va cm timber placed hori- zontally in the mole in its longitudinal direction, and fastened to it with one 22 mm bolt. Both those limbers shall be held securely in place by large stones heaped up above and round them. Besides that, every other frame shall be provided with two horizontal connecting-pieces of 231/2 by 231/a cm timber placed obliquely one on each side. Each of these braces shall be tenoned into the topmost tie, fastened to the hindmost longitudinal tie-beam in the quay with 22 mm bolts, clamped to the longitudinal timber in the mole and fastened to it with one 22 mm bolt. In the outmost bay and two other bays there shall be built a light foot-bridge leading from the quay to the top of the mole. It shall be constructed in the following way. Four beams of 21 by 21 cm. timber shall be laid across the two 231/s by 231/a timbers, and fastened to them with 22 mm. bolts. Across these timbers there shall be laid five pieces of 13 by 13 cm. timber about 1 m. apart, fastened to them with one 19 mm. bolt at each crossing. Above these timbers there is to be laid a decking of 73/4 cm. planks fastened with two 18 cm. pine-spikes to each beam. At both ends of the bridge, the one in the mole and the one at the platform of the quay, there shall be placed a step of 21 by 21 cm. timber. A suitable recess shall be left in the slope of the mole to receive each bridge. The 21 cm. timbers shall on the underside be provided with a pair of cross-wise placed braces of 23x/a by 23^2 cm. timber notched together at the middle. The connection between the quay and the innermost wider portion of the mole shall be arranged as shown by the plan of the quay on Plate III. Flush with the row of the concrete-blocks there shall be placed another two blocks 3,5 m. apart but so high as to have the uppermost 23^2 by 231/2 cm. timbers resting immediately on them fastened to them in the same way as the ties are fastened to the other blocks. On these timbers and the longitudinal timber in the mole there shall rest double beams, 26 cm. in breadth and with a total height of 55 cm., one above each block and two in each interval at equal distances apart, fastened to each of the three supporting timbers with one 25 mm. bolt. The two timbers of the double beams shall be fastened together with four 25 mm. bolts and three oak-keys. Above these beams there are to be laid longitudinal beams, cross-beams and a decking arranged like those of the quay itself. One of the oblique compartments of the connecting-bridge shall be supported with two pieces of 26 by 3P/2 cm. timber, which shall at one end be notched down'into the topmost ties of the innermost supporting frame and fastened to them with two 25 mm. bolts, while the other end shall be scarfed together with the uppermost timber of the double beams, each scarf being strengthened by an oak-pin. The prolonged portions of the supporting beams shall then rest on these timbers. The other oblique compartment shall be supported by a double beam extending obliquely between the 5th block and the longitudinal timber in the mole. A recess shall be formed in the slope of the mole to receive this construction, and the timber in the mole shall be anchored with 25 mm. holding-down-bolts placed in the mole P/2 m. apart. Along the whole length of the quay there shall be laid a double track of 7 kg. rails, 65 mm. in height, with a gauge of 60 cm., at a distance of 2,5 m. from centre to centre; the rails shall rest on steel-
