Model of a jetty, or landing-pier, designed for Douglas,Isle of Man , upon the same principle, constructed of wirerope, in lien of chain plate and rods; the vertical rods arecomposed of iron tubing, the whole supported on screwpiles, with a tidal staircase at the extremity.

[The screw pile, the invention of Mr. Alexander Mit-chell, of Belfast , is one of great interest and value; it hasbeen employed for the foundations of lighthouses, beacons,jetties, and other submarine works (see Minutes of Pro-ceedings of the Inst, of Civil Engineers , February 22,1848).—S. C.]

Speedy louis, invented to expedite the hoisting of lightstones in the erection of buildings, &c. By this con-trivance it will he seen that it is impossible to lose any ofthe component parts, as may be the case in the ordinarylouis, which consists of five separate pieces, the loss ofany of which renders the remainder useless. This model .has been tested by the hoisting of a block of 5 tons ofPortland stone with safety. An ordinary louis for com-parison.

79 Shield, Joseph, Newcastle-upon-Tyne —Producer.

Model, showing the process of manufacturing shot fromlead.

[Shot are made by melting lead, with which, usually,some arsenic is combined, at the top of a high tower.The melted metal passes through a cullender, and fallingthrough a large column of air at length falls into a waterbutt on the ground. The heights of these towers varyfrom 200 to 300 feet. In the progress through the air, thesphericity of the shot is obtained; and after being cooledin the water they are selected, mixed with a littleplumbago, and put into a small octagonal cask, which ismade to revolve by mechanical power: in this way allroughness is removed, and the shot are polished.—R.
