316 THE MARINE REVIEW August, 1910 Fic. 16--SmitH SwHopr Orrice, Toor Room, Luncu Room, LAVATORY AND 17. Very few blacksmith shops are provided with facilities for the com- fort of the workmen. In machine shops elaborate washing facilities are usually provided for the men, while in blacksmith shops, where they are more needed, they are seldom found. In the arrangement shown the neces- sary office space, lavatory arrange- ments, etc., are provided at a mini- mum cost in space. (To be continued.) Liverpool's New Dock Scheme The Mersey Docks Board on July 7 decided to construct the following new works, which are estimated to cost $2,500,000: A dock about 1,020 ft. long, in a po- sition immediately north of the Rim- rose river wall, Seaforth, having an entrance 120 ft. wide, and a sill laid at a level of 25 ft. below old: dock sill, and so constructed as to be available when specially required as a graving dock, the floor being laid in concrete at a level of 29 ft. below old dock sill, with a center line of keel blocks and side lines of blocks where necessary; pumping machinery, entrance to cais- son, capstans, etc. A single story shed 900 ft. long and 100 ft. wide, on the north quay of the said dock, with the necessary paving, roadway, railway sidings, etc. Four movable cargo cranes on the north quay with a range of travel of the full length of the shed. The necessary embankments. and _pierheads and dolphins of timber, to form an entrance channel 400 ft. wide at its mouth, leading to the dock. The deepening, by dredging, to a depth of 27 ft. below old dock sill of the entrance channel and the adjacent portion of the river bed and foreshore. and Harbor. - late. WATER CLOSETS. These new dockworks are really ad- ditional to the Gladstone system of new docks already authorized, which also being designed to accommodate vessels of 1,000 ft. in length, and esti- mated to cost $17,500,000, will be built as soon as the British shipping trade regains its wonted prosperity. As, however, it has been made clear within the last year or two that the future of the New York trade lies not with the 10,000-ton cargo boat, but with the 40,000 or 50,000-ton com- bined passenger and cargo steamer, and that. ships of this type and size are already under construction or contemplated, the Mersey docks board deemed it advisable' to. take proper steps for the proper accommodation of such steamers before it is too It has, therefore, been decided to make a beginning with the con- struction of one dock at present for these mammoth vessels, and this new dock will be remarkable for one of such huge dimensions in that it will be so constructed as to enable it to be used also as a' graving. dock for the largest liners. The dock, as be- fore stated, will have a total length of 1,020 ft., an'entrance width of 120 ft.. will dock 'vessels 1,000 ft.. long and of 50,000 tons, while the depth of water 'on 'the sill at the lowest tide will be 35 ft., and on the highest tide 46..ft. -6.iny. The length and tonnage of the big- gest liners now afloat compare as fol- lows with those building and con- templated: 'Tonnage.

Jt is intended to have the dock ready for commission in three years. Lloyds Rules for Internal Combustion Engines for Marine Purposes Lloyds register of British and For- eign shipping are about to issue rules for internal combustion engines for marine purposes. These have just been adopted by the committee of the society... They greatly simplify the registration of the increasing num- ber of vessels fitted with oil engines, particularly launches. The rules: are divided under four headings. The sec- tion concerning construction strongly enforces the importance of accessibil- ity for examination and repair, and requires that engines of over 60 brake horsepower, which are not reversible, and are maneuvered by clutch, must be fitted with a governor or other ar- rangement to prevent the' racing of the engine when declutched. The cyl- inders, it is also indicated, are to be tested by hydraulic pressure to twice the water-jackets of the, cylinders to the working pressure to which they will be subjected, the water -jack- ete. of the cylinders to. "50. -- 1b; per Sq. it... and the exhaust- pipes and silencers to 100 Ib. per sq. in. In regard to the size of crank, intermediate, and other shafts, for- mulae and tables are given for ordin- ary mild steel; where special steel is employed. the sizes are to be submit- ted for consideration. The tables are comprehensive, embracing smooth-wa- ter and open sea service boats, and engines of 4-stroke cycle and 2-stroke cycle. Regarding the fuel tanks and connections--another of the sub-head- ings--it is pointed out that the sepa- rate fuel tanks are to be tested, with all fittings, to a head of at least 15 will
