RECLAMATION OF TIDE LANDS. 385 LU'/.. 26 u. o < H Fig. 7.—Relative position of borrow pit, dredge, and levee. the toe of the levee. Where the ground is firm enough to use a trac- tion machine this difficulty is overcome as the machine can be run on the berm between the toe of the levee and the pit, as shown in the an- nexed cut (fig. 7). When a sufficient amount of material has been placed in the embankment to secure the proper width and cross sec- tion it should be dressed to a smooth surface and planted in some species of grass that will form a tough sod. South of Virginia the Ber- muda grass is the best for this purpose, while along the north coast red top or herd's grass seems to be best suited. WAVE PROTECTION. Where a levee is exposed to high winds it should be protected from wave wash when first put up until the sod is formed and the material thoroughly settled. This can be done as follows: Plant a row of 6 by 6 posts along the berm about 3 feet from the toe of the levee and bolt a stringpiece 4 by 8 to the front of these posts at about the elevation of high tide. If the posts are more than 6 feet oui of ground, another piece should be bolted on about 1 foot above the ground. Drive a double row of sheet piling 2 by 6 or 2 by 8 on the front side of this stringer, inclining about 1 foot horizontal to 6 feet vertical toward the levee. The pieces should be driven so as to break joints with each other and penetrate the ground 3 feet. The planking should be further secured by placing a waling piece 2 by 6 or 2 by 8 on the front side opposite the stringer and securing it by screw bolts passing through the waling strip, sheet piling, and string- piece at intervals of 6 feet. At each post the barrier should be braced by a strut of 3 by 8 secured at one end to the top of the posts by means of screw bolts or spikes and extending
