line f. Whatever is left abaft the foot -rail mould muft be 

 alfo left abaft the line G for the mould of the breaft-rail, 

 upon a fuppofition that both moulds are made to fuit the 

 aft part of the balluilers. The half-breadth of the rails 

 only being laid off is the moil correa, for then the moulds 

 will be made in two halves exaftly alike, and may be 

 fcarfed and nailed together in the middle from any ftraight 

 line. The middle line and outfide of the timber Ihould be 

 marked on each mould. 



To Lay-off the Taffrail and Quarter- Piece. 

 The form of the taffrail and quarter-piece, in /g. 6, 

 being laid off from the plan of the ilern, P/ate I., fquare 

 up from /^. 5. what the ifern projeds at 24, to the quarter- 

 deck in fg. 4, and continue it upwards parallel to the fide 

 llern-timber to the top of the fide, as you fee ticked ; then 

 fet off the half-breadth of the ftern at the quarter-deck, and 

 likewife at the top of the fide on the ticked line 2^, fg. 6, 

 taking the round-aft at each place, and fet it aft at the 

 correfponding heights from the above ticked line in Jig. 4. 

 This will give the ticked line T, being the midlhip-timber jt 

 the upper part of the Hern, or the fore-fide of the taffrail 

 at the middle line. Let this ticked line T be anfwerable to 

 the line A A, Jig. 9. 



Drop as many perpendiculars from the top of the taffrai' 

 and outfide of the quarter-piece, as in the left-hand of Jig. 6, 

 as may be thought neceilary. Take the perpendicular heights 

 from the bafe line in fg. 6, to the feveral perpendiculars 

 lalt mentioned on the taffrail and quarter-piece, and fet 

 them up from the bafe line in Jig. 4, and ftrike in the hori- 

 zontal lines 2 2 to 31, the laft being the height of the taf- 

 frail at the middle line. Take fq'jare from the middle line 

 in Jig. 6, where each perpendicular interfefts the upper part 

 of the taffrail and outfide of the quarter-piece, and fet them 

 off from the middle line on the ticked line 2), Jig- 6; then 

 take the diftances from the ticked fine 25, to the round of 

 the Hern on a level 26, 26, at each hne fquared down, and 

 fet them off on their correfponding lines lall ftruck in Jig. 4) 

 from the ticked line T, forward in the direftion of the 

 ticked lines. A batten pinned to thofe fpots will give the 

 ticked curve Q in the middle of the quarter-piece (which, in 

 a thwartfhip view, is the aft-part uf the timbers, fuppofed 

 to be continued to the heel of the quarter-piece) ; then 

 abaft this ticked line fet off the aft-fide of the taffrail, and 

 continue it to the heel of the quarter-piece ; that will deter- 

 mine the aft-fide of the quarter-piece, from which fet for- 

 ward the fiding of the quarter-piece, and that gives its fore- 

 fide, as it will appear when in its place. 



The rims and llools mis^ht be all laid off on the floor ; 

 but it would appear confufed on the plate, and perplex the 

 reader. And, indeed, the making of a handfome quarter- 

 gallery depends chiefly on the performance on the fliip ; 

 therefore ao explanation may give more ufefal information 

 than a drawing. 



The length of the rims and ftonls being determined in 

 ^g. 4, the breadth abaft need only be taken from Jig. 6, 

 and let the (fool at the quarter-deck ferve for all the rims 

 and tlools in the quarter-gillery, keeping the foremolt end 

 well. At lead, the fame mould that moulds the llool at 

 the upper parts of the lights, may mould the riin at the 

 lower part of the fame lights, becaufe the munions in the 

 quarter-gallery fliould be all out of winding ; and in order 

 to make them fo, the ftool at the quarter-deck will require 

 to be longer than the rim at the lower part of the lights, 

 more or lefs, according to the winding of the top-fide. 

 Tliis might be allowed for exadly in laying-off the Itools ; 



but it is better to leave the llool at the quarter-deck long 

 enough, and proceed in the following manner. 



Suppofe the rim at the iecond counter-rail to be trimmed 

 agreeable to the form of the ilool at the quarter-deck, and 

 to be in its place on the fhip ; and fuppole the ftool at the 

 quarter-deck to be fayed to the fide : then fet off the 

 breadth of the ftool at the aft part, and nail a batten from 

 thence to the rim. Then fet off the munions on the rim, 

 and at every munion on the rim hold a ftraight batten from 

 thence to the under fide of the ftool, and look them out of 

 winding with the batten at the aft part, or with each 

 other, obferving to fet off the fame diftances at the under 

 fide of the ftool from the aft part as they are on the 

 rim. Then the wood may be dubbed away, or the ftool 

 taken down, and mould the under fide (which will nearly 

 agree) to every fpot, with the fame mould as the rim waa 

 moulded with. Then you may be certain the fadies will 

 be out of winding, and, if required, would Aide from one 

 end of the gallery to the other. Then, when the munions 

 are fet off, you may find a greater diftance from the fore- 

 moft munion to the fide on the ftool, than there will be on 

 the rim ; but this cannot be avoided, and is of but little 

 confcquence ; becaufe the canting-livre, or confole-bracket, 

 is introduced on purpofe to intercept the finilhing of the 

 gallery with the fhip-fide : for if the ftool at the quarter- 

 deck was to be no longer than the rim at the fecond counter, 

 it would fall into the hollow of the top-fide at the foremoft 

 end, and the foremoil munions in the view of the fheer. 

 Jig. 4, would appear to rake mire than the after ones • 

 and when looking from before the gallery, the munions ill 

 the lower and upper gallery would not appear out of 

 winding, but the whole gallery would feem in confufion { 

 therefore the upper gallery muft undergo the fame opera- 

 tion, and then it will bear to be viewed in any direftion. 



It isrequifite, at leait, to lay off the ftool and rim of the 

 lower gallery, and allow for the winding of the top-fide, in 

 order to mould them nearly ; but by following the above me- 

 thod in the performance of the work, any little error that 

 may happen will be corrected. 



To lay off the lower rim B, and middle ftool c , Jig. 4, to 

 make the moulds to, transfer the height of the upper fide 

 of the lower rim B, and upper ftool c, injlg. 4, continued 

 forward to fquare timber 32, to the body-plan, P/ale VII. 

 Jig. 5, upon its correfpondii;g fquare timbers. Then take 

 the half-breadths as far forward as fquare timber 32, and fet 

 them off from the middle line on their correiponding timbers 

 in P/ate X. Jig. 5, and produce the half-breadth lines, and 

 thicknefs of the planks A and B without it, as far aft as in 

 the plan, fg 5. 



1 hen Iquare down the knuckles of the upper counter from 

 _fig. i^. to Jig. 5, and fpring an arc to the round-aft, which 

 will be the fore-fide of the upper counter-rail. Next fweep 

 another arc to the thicknefs of the upper counter-rail, pai 

 rallel to and abaft the ticked curve, and the upper counter- 

 rail will be ftiewn in the plan. Jig. 5. Then take the half- 

 breadth of the upper fide of the upper counter-rail to the 

 outfide, B, in fig. 6, and fet it oft from the middle line in 

 Jig. ^, on the ticked perpendicular 13, as fquared down from j 

 the outfide knuckle. Thence form the curve F, or outfide ■ 

 of the lower rim. The ticked parallel hne within is the out- 

 fide of the munions, upon which fet off the ftations of the 

 lights, making them all alike, and the munions 44, 45, 46, 

 47, between. Square up the munions to the upper fide 

 of the lower rim in Jig. 4 ; and from the fpots fquared up 

 ftrike lines parallel to the fide itern-timber, to the under 

 fide of tlie middle ftool. The aft part of the middle ftool is 

 already laid off mfg. 5, and the form of the outfide may 



be
