keep th-> chains clear' of the hull. The anchor is let go from "the■ bow,-nnd the chains run out as at present; but when the neces_sary length is pnyed out, the cablel3 made f.ist.to.the bight of the girdle round the bow. Tlie girdle is then let go; and the vessel rides by doub'ed chain passed through the fore quarters, and this double chain or girdle takes' ths single cible by which the sbip rides. In theory this plan is correct, but there lias always been a difficulty in prnctira ly .carryinpr it out in. a seaway. Mr Milherg.Jodeeri a moikl of hi* ril'in at the Po'ytcchnic Institution io London, in IS4G, anil asserts tliat. his experiments oh a large sailing . boat convince him that suspended c'inins from a point about a third or so from the ship's hows, according to the length of the keel ami the rake of the stem and stern. ar« a compUte an Mote to the leverage, and that if th's system were adopted there would ■be fewer ships lust from driving either by breaking the cables or dragging the anchors. Cables p irt by the gulden j'-rk*, and not from steady strains. Alii, this ia known io professional men. They see it. but the remedy is not so simple of application as Mr Milbsrg imagines. He shows us..how one Hiiclifir may be let go. and the chain seemed to a girdle. For a second chain we presume nnothi-r g'rdle would have to he provided, for the single chain' could not be hove in during a ga'e tn-attach the second cable to the bight Atpiin. there is tm clanuer. from diagning imchots in fine nea her, at d in hal wvather, when the seai are bi caking uvcrtlic hows, it would bo a hazardous wmk to shackle oti the regular bower cab eto a girdle.' In fact, it eou'd i>or be done on ,bnar;l deeply laflen vessels The attachment' m;ght, .therefore, be made irilnnrd, and tl.is wuul>t n cessitate the mr.kinjr of-a very large ape"ture. big 'c.iouuh to run tlii<-e chains together, which, would le iou'.d objectionable. To giv.e the ship rno'e c! am when TWinv,,tl>e etuis of the girdle ciiain would have to be payed out. and this wou'd be open t<> the faul of having Ihr c -ebtins instead ut one. The loose 'Vain hiinging over the bow, or that part tio'ln thebawto thu beni-inu1 on put of th; girdle, would liq luiblt? to chafo ve ry considerably by flp^'n x agdnst th'! forward part of. the ship. Thtreis iuio:h«i ol» JBC">io 1, and that is, when liding among the fl'et of vessel on a titiai shore, it is necessary to shorten tht? cibld at- lime.o, and also to veer out. Tlih new mßchiitiical aiK-hnr-if ts wnuld run in a double aible, or girtlje, quickly etiogh. and ti.ere is no difficulty in veering; but all this would lead to the use of con-i----de ably nmre chain than is now neee^sa-y.
