After tlkostt tanks are foudecf, tho apperttire» throtigh which.thtt »poit in receded are closed by air -tiffin doors, and the vessel removed to her berth. Iron pip» k 13 inches diameter, one from the bottom of each sulk,. ats * cuttpled by a breeches pipe under the decfe to * ttofflv pipe. -0 inches diameter, whicb passes along to th« sfctr of the ship, and is here connected by a ■tout leather hose with a targe cast-iron main on shore. Uia pneumatic pnmp» Is then put in action, iir b fofcid into the tunics, and the spoit id «i«ickty expelled through the iron pipes. The vessel is Btted with com* pounif engines of 2S horse-power nominal, the pnenmftlh* cylinder. -0 inches in diameter, being curried on the same framing. The steam power may by suitable gearing be employed at pleasure, either to dredge, to propel the ship, or to discharge the spoil. There are all)o> stsam, winches for raising and towering the bucket ladder, and varying the position of the dredger while at work. Tha apparatus was practically tested on February 10-, on the Jlillwail Cocks, in the presence of a, largwtWtjr et anaineer» and others, who', while they eh« limnKohy of ita construction, wer# of Its. success. As before lUiiiiiiilfelPffliFfcjiiiTii i to be effected by the use of tfiia lnv«ntiw 3»s<aMßthing enormous—indeed, we may mention that,,whereas' the ililtwalt Dock Company's drsdtring Uuit year trader the old system coat at the rate ot lid. per cubic jard, it now, by using " &uefchamfs pfttant Dradging Plant," costs only 3d. per yard. In the colonies, and, in fact, everywhere where docks, harbours, and bars require to> be kept clear, the invention will undoubtedly prove of the greatest practical value, for we are assured the discharge of spoil by nuMSUMSic power has been formcf to be onty applicable when the material is of a soft serni-tlaUl natunr. but that gravel, coat, and miscellaneous mttttiu! have been readily thrown out. The friction la the pipe exceeds that of water by but a sinafl percentage, and this ia ehietty due to the specitic gravity ot the soil.
