The edge of each
manhole is stiffened by a welded iron ring. The surface of the mooring
link that comes in contact with the shackle and mooring chain is steeled.
The gas holder rests upon a plate bent up on each side, and riveted to the
keelson, and is prevented from rolling by four gusset plates, with two
short pieces of angle iron riveted thereto at the ends and coming in
contact with the holder, and at the ends by angular plates, and angle iron
riveted on each side and riveted to the keelson. The superstructure
consists of four legs of angle iron 2-1/2 inches by 2-1/2 inches by 5/16
inch, the upper ends of the legs being attached to a square flanged plate
for supporting the lighting apparatus. Four wooden battens of pitch pine,
4 inches by 1-1/2 inches, and bolted on to each cant of the angle iron
superstructure, with 7/8 inch galvanized iron bolts and nuts.

PROJECT FOR A ROADSTEAD AT HAVRE.
The present port of Havre is absolutely insufficient to answer the ever
increasing requirements of commerce. Its entrance, which is too narrow and
not deep enough, does not permit steamers to go in, come out, and perform
their evolutions with the rapidity required by our epoch.
