and let them be ftruck on the floor in the body-plan and 

 half-breadth plan. Then proceed to run the buttock-lines 

 in the (heer-plan, /^ i, as direfted in the conftruftion of 

 the iheer-draught, Plate I. The buttock-hnes, the fquare 

 timbers, and likewife the water and ribband-lines, Ihould 

 be made to agree to the greateft exaftnefs. 



The moulding edges of the other tranfoms may now be 

 laid off from the buttock-lines in the (heer-plan,/^. i ; but 

 if they are laid off in the half-breadth plan, then only half 

 or one fide can be reprelented. The beil method, there- 

 fore, will be to lay them off in fome convenient place on the 

 floor by themfelves, whereby both fides may be reprefented, 

 and there will not be then fuch confufion in the lines. This, 

 for dittinftion, may be tenned plan of the tranfoms, as 



Plate IX. Jig.i. , ■ y A A 



The moulding edge of the wmg-traniom is ab-eady de- 

 fcribed to which the mould is to be made ; the fiUing- 

 tranfom is next, which lies between the wing and deck ; 

 and as it lies horizentally, the defcription of it will fuflice 

 for all the other tranfoms that come under the deck, which 

 alfo lie horizontally. 



As there is no more trouble in laying-ofF a tranfom which 

 IS fided Itraight,. and Ues level, than there is in laying-ofF a 

 water-line, Itrike on each fide of the middle line M, in the 

 plan of the tranfoms, Plate IX. fg. 3, the half-thicknefs of 

 the dead-wood or bearding-line, a a, taking it from the body- 

 plan, _/r^. 2, (and as low down as the deck-tranfom the 

 inner poll is fided the fame) ; likewife the buttock-hnes. 

 Take from the half-breadth plan the fquare timbers 32, 33, 

 34> 35> 3^' ^"^ ''^^ proof timbers i and 2, and ttrike them 

 in the plan of the tranfoms, ^/T^. 3, at right angles with the 

 middle line ; alfo ftrike in the cant of the fafhion-pieces 

 F, M, A. Then Itrike a perpendicular line, P, in the flieer- 

 plan, _/f^. I, at the interfeftion of the upper edge of the 

 wing-tranfom, at the fore-part of the rabbet ; likewife 

 another at right angles with the middle line, at the aft-fide 

 of the wing-tranfom, as P P, in the plan of the tranfoms, 



fS- 3- 



Now from the perpendicular P, above mentioned, called 



perpendicular of the tranfoms, take the diltance in the flieer- 

 plan, _/?^. I, to where the upper fide of the filling-tranfom, 

 F, interfefts the fore-fide of the rabbet of the poll or beard- 

 ing-line B, and fet it off from the fame hne P P, in the plan 

 of the tranfoms, _/?f. 3, at the middle line, fquaring a line 

 acrofs to each bearding-line ; which line will be the after- 

 part of the filling-tranfom at the middle line, Obferve 

 where the bearding-Une, C, of the poll, in the fheer-plan, 

 fig. I, comes before the fore-fide of the rabbet, to take the 

 aforefaid diftance to the bearding-line of the poft, as that 

 terminates the after-part of all the tranfoms ; then take the 

 diftances in the fheer-plan, fig. i, from the perpendicular 

 line P, to where the line reprefenting the upper fide of the 

 filling-tranfom interfefts the different buttock-hnes i, 2, 

 3, 4, and 5, and fet them off from the fame line P P, in the 

 plan of the tranfoms, ^^. 3, on their correfponding but- 

 tock-hnes on each fide of the middle line. Then take the 

 diftances in the body-plan, fg. 2, from the middle hne, to 

 where the upper fide of the filling-tranfom, c, interfefts the 

 fquare timbers, and fet them off on both fides of the middle 

 line on their correfponding timbers, in the plan of the tran- 

 foms, fig. 3 ; then by pinning a batten through the fpots 

 on the buttock-lines and fquare timbers, to its after-part at 

 the fide of the bearding c c, the moulding edge or upper fide 

 of the filhng-tranfom will be defcribed on one fide the 

 middle line ; the mould may then be made to that fide, and 

 canted over, and the oppofite fide marked thereby, being 

 tire thus to have both fide» alike. This filling-tranfom 



having been laid off horizontally, of courfe, when mould- 

 ing the fiUing-tranfom, the mould mull lie in an horizontal 

 pofition ; but having fo little room between the wing and 

 deck- tranfoms, it becomes neceffary to give the filhng-tran- 

 fom a round-up between both. Thofe who would be more 

 correft in laying-off tranfoms, that have a round upwards, 

 may fee the fubjeft farther explained in the following me- 1 

 thods. 



To lay-off the deck-tranfom, ilrike a ftraight line in the 

 Iheer-plan, fig. i, at the under-fide of the deck, at the 

 middle line, to take that part of the hang of the deck only, 

 which is terminated between the rabbet of the itern-poft and 

 the fafhion-piecc, as H, fig. 1. Then take the round of 

 the deck R, at every buttock-hne, as under the body-plan, 

 fg. 2, and fet them off below and fquare to the itraight 

 line H, in the flieer-plan, fig. i, marking parallel lines 

 thereto, to interfeft their correfponding buttock-linei, 

 which gives the moulding edge of the tranfom. Proceed in 

 the fame manner with the lower edge, by ftriking a hne for 

 the lower fide of the tranfom at tlie middle line parallel to 

 the former ; and fet the round down, as before, upon any 

 buttock-line. 



The upper and lower fides of the deck-tranfom being ob- 

 tained on the buttock-hnes, in the flieer-plan, /ig. i, transfer 

 their heights from the ftieer-plan, _/J^. i, to the body-plan, 

 fig. 2, refpeftively ; then by pinning a batten to thofe 

 heights, the upper and lower fides of the deck-tranfom, J J, 

 may be reprefented in the body-plan, fig. 2. 



The lines above mentioned, in the fheer-plan,^. i, pa- 

 rallel to the fheer of the deck, at the interfeftion of the 

 buttock-lines and fafliion -piece, fliould be continued aft to 

 the perpendicular P ; then take the (Jiftances from that line, 

 in the direftion of the parallel Imes, to the buttock-lines and 

 fafhion-piece, and fet them off fquare from the faid line P P, 

 in the plan of the tranfoms, fig. 3, on their correfponding 

 buttock-lines and fafhien-piece. Next take the half-breadth 

 from the body-plan, ^g. 2, at the interfeftion of the deck, 

 at the fide, with the fquare timbers, and fet them off on their 

 correfponding timbers from the middle line, in the plan of the 

 tranfoms, fig. 3 ; then by pinning a batten to thofe fpots, 

 this forms the .moulding edge of the deck-tranfom D D. 



The tranfoms under the deck, all lying horizontally, may 

 be laid off by taking the diftances of the buttock-lines and 

 bearding-line from the perpendicular P, in the fheer-plan. 

 Jig. I, on the upper edge of each tranfom, and fetting them 

 off on their correfponding buttock-lines from the fame per- 

 pendicular P P, in the plan of the tranfoms, _fig. 3 ; and 

 alfo at the timbers from the middle line in the body-plan, 

 _/%. 2 ; and fet them off from the middle line on their cor- 

 refponding timbers in the plan of the tranfoms, ^g. 3 : a 

 batten pinned to thofe fpots will reprefent the moulding 

 edges of all the tranfoms. 



To prove the interfeftion of the tranfoms with the fide 

 of the fafhion-piece, which is the end of each tranfom, as 

 already laid off in the plan of the tranfoms, fig. 3. Thus, 

 where the upper fide of the wing-tranfom in the body-plan, 

 _^g. 2, interfefts the foremoft fquare fafhion-piece S, level it 

 out to interfeft the cant-fafhion-piece c. Then take the 

 nearell diftance from the cant-fafhion-piece at that place to 

 the middle line, and fet it off from the middle line in the plan 

 of the tranfoms, 7?^. 3, in the direftion of the line of the fore- 

 mofl fafhion-piece F. In the fame mannerprove the filling and 

 dcck-tranfoms. Take the diftances from the middle cant- 

 fafhion-piece to the middle line along the upper fide of Nos. 

 1,2, and 3 tranfoms in the body-plan,^. 2, and fet them off 

 on the middle cant-fafhion-piece M, from the middle line in 

 the plan »i the tranfoms, fg. 3, as before. Take likewife
