all the eifecl 'of lodging-knees, and that of tiie tranrveffe 

 frames more than fupphes the fupport given by hanging- 

 knees. 



Tliis would occafion a confiderable faving in large vefTels, 

 on account of the great price of knee-timber fit for them; 

 which, for that of 30 feet meeting, is near ten pound per load 

 and for the fmalleft kind, taken at the dock-yard, not lefs than 

 SI. I5s. , 



4th. Plank of half thfeufual thickneis may be ufedfor lining; thinner plank- 

 the great fupport given by the fore and aft ribs rendering any*^^^'^ 

 life of infide plank, to ftrenglhen the velfel, needlefs, and con- 

 fining its purpofe merely to prevent ballad, or other matters," 

 from getting between the timbers, fo as to reft on the outfide 

 plank. 



This will al fo caufe a faving of confequence in large yeflels ; 

 plank of all kinds, but particularly that' of great thicknefs^ 

 being the next deareft article to knee-timber. 



5th. It is probable a much lefs quantity of limber might be leCs quantity of 

 ufed with fafety ih this method, on account of the great ftrength "^^'^^"^'^> 

 produced for the timber ufed. ift. By the triangular framing. 

 2d. By every timber having a folid fupport at each extremity. 

 3d. By the increafe of thicknefs from in to out all along the 

 fore and aft ribs, being very great in proportion to the tim- 

 ber ufed. 



6th. It is probable, veflels built in this method will laft durability, 

 many years longer bef6re decay; becaufe the ufe of fmall 

 timber admits of a kind more fpiny and durable than the large, 

 which is often dotard, and never lafts fo long; and alfo becaufe 

 this conftrudion admits of a free circulation of air among the 

 timbers, than which nothing is known to contribute fo much to 

 their prefervation. It is moreover conceived, that the timbers 

 being prevented from working by the folid fupport each has at 

 its extremities, will caufe the vetfel to wear lefs, and at the 

 fame time render it fafer, by diminithing the danger of ftarting 

 planks, or otherwife caufing bad leaks, 



7th. The timber of confiderable ilze ufed in this method is 

 almoft all nearly ftraight, or of very little curvature, on account 

 of its running fore and aft. 



This kind is much eafier to procure than large compafs 

 tiaiber.
