On GOTHIC JRCHITECTURE. 15 



each of the others, (as B or G), and let their pofition be fuch as 

 to cover the infide of the poft, (as marked by Httle circles in 

 fig. 6.), fo that, when feen from between the I'ows, the lower 

 part of each poll fhall be concealed from the view, and prefent 

 the appearance of a bundle of rods, (fig. 2.). 



Things being thus difpofed, the fkeleton of a thatched roof 

 may be formed, by means of the loofe ends of the rods. This 

 is reprefented complete in Plate II. figure rj. & 16. ; but the 

 ftrudlure being rendered intricate, by the mixture of different 

 fets of forms, I have, for the fake of diftindnefs, defcribed each of 

 them feparately, and have reprefented them by feparate draw- 

 ings, with each of which a ground-plan is connected. 



A ROD from one of the polls, being fo bent as to meet a fimi- 

 lar one from the poft immediately oppofite to it, in the middle 

 of the fpace between them, let the two rods be made to crofs 

 each other, and let them be bound together at their croffing, 

 (PI. I. fig. 3.). Thus will be produced the exadl form of the 

 Gothic arch. The fame being done with each pair of op- 

 pofite ports, and a fet of pointed arches being formed, let them 

 be connedled together by means of a ftraight pole, laid upon 

 the forks of the crofling-rods, and botind to each of them, 

 (fig. 7. & II.). 



Then let a loofe rod be brought from each of any two con- 

 tiguous pofts in the fame row, fo as to form a pointed arch, fi- 

 milar to that juft defcribed, and nearly of the fame height. This 

 being done with every two contiguous pofts, (fig. 8- & 12.), and 

 a new fet of pointed arches being thus produced, ftanding op- 

 pofite to each other in pairs, let each pair be bound by a hori- 

 zontal pole lying on the oppofite forks, and crofling the lon- 

 gitudinal pole, defcribed above. 



Two of the rods of each corner poft, and three of thofe 

 of each of the others, being thus difpofed of, we have one 

 of each corner poft, and two of each middle . poft ftill to em-
