11 sleepers fastened with spikes to the decking of the quay. The two lines of rails shall be carried on across the oblique connecting-bridge inwards to the top of the wider portion of the mole and run along it to the shore. They shall in five places be provided with switches. Except where it immediately adjoins the top of the mole, the quay-wall shall all round be pro- vided with a top-edge-listing of 151/? by 151/? cm. timber, fastened like that of the main pier. The listing is to be interrupted at the three bridges, but shall be placed along both their sides between the steps. Joints in the timbers of the quay-wall shall be executed like joints in the corresponding timbers of the main pier. The Contractor must consult the Control concerning details in the construction of both the pier, the quay and the frameworks for the lighthouses. Examinations of the bottom. The examinations of the bottom described beloxv were made partly in August 1906 and October and November 1908, partly in March 1912. In 1906 some borings were made in the Grandi with a cylinder of xvrought iron 26 mm. in diameter provided with a point of wrought iron; it was driven in partly with a 10 kg. sledge-hammer, partly with a 6 kg. maul. The Grandi proved to consist of firmly bedded stone and gravel. The cylinder could be driven down to 3,15 m. below low-water level, the average rate of sinking per 5 strokes being from 1,5 to 5 cm.; in one single place near the land, 3 m. below the surface the cylinder sank 10 cm. per 5 strokes. In 1908 there were taken 336 borings in the area which is to be excavated to a depth of 5 m. below low-xvater level. The ground bored through consisted of layers of sand and clay mixed with small stones down to 5,8 or 6 m. In two places only solid ground was reached at a depth of 5 m. In March 1912 borings were made in 5 lines, which are shown on Plate IV together with the result of the borings. The borings were made with a hammer-down auger, and samples were as far as possible brought up from every boring.
