J70 IMPROVl^O MBTirOD OF CONSTRUCTING SHIPS. 



8th. Short-top timber and coarfe butts can be worked up 

 to advantage, inftead of being fold for lefs than half coft, 

 or burned ; as this kind will do fufficiently well for the 

 i)umber of thort ledges in the deck frames, and to fupport 

 the lining at the floor, which are wanted in this mode of 

 building. 



9th. VefTels built in this manner will not be fo liable as 

 others to hog, or have their backs broken, on account of 

 the great flrength length-ways, caufed by the fore and aft 

 ribs. 



lOLh. Veflels fo built will be drier, from the circulation of 

 air before mentioned, and having the floor-lining detached from 

 tjie timbers ; which quality renders this conftru6tion parti- 

 cularly valuable for the fliips ufed in the Eafl and Weft India 

 trade. 



The advantages above recited relate to vcflels entirely form- 

 ed in this manner. It fiiould be known alfo, that parts of this 

 plan may be applied with profit. The mode of framing the 

 decks, for inftance, might be ufed to fave lodging-knees in 

 veflels built in other refpeds in the ufual mode. Other parts 

 of it might be applied to the ftrengthening old veflels, which, by 

 this means, might be made to laft many years, after they would 

 other wife have been unferviceable. 



The principles of this method of building are capable of 

 being extended ftill further than they are in the veflel here de- 

 fcribed ; the triangular framing may be even adopted to the 

 conftruflion of fore and aft ribs, fo that thefe could alfo 

 be conftrufted of fmall timber, if required. Thus, by this 

 means, the former barrier to the increafe of fize in fliips is re- 

 moved, as it no longer now depends on the fize of timber ; 

 and fliips of any dimenfions required may be formed, of any 

 firenglh requiflte, of fmall timber.
