equal Part, divided by Diagonal Lines into 

 ten Parts 5 each of which correfpond with the 

 Divifions of ten Links in the Chain. This 

 Subdivifion is numbered on the Sides, 2^ 4^ 

 6, 8, and in the fame Manner on Top. If 

 you imagine the Top Figures to denote Units, 

 andthofe on the Side Tens, 'tis then plain, 

 that, if the CorapaflTes be extended from the 

 Point where the lixth Line interfeds that no- 

 ted 3, to the Point where the Line denoting 

 70 is interfecled by the fa id 6 th Line, that 

 Diftance (hail be three Chains, 76 Links. 

 This appears yet more plainly by the Dots 

 made in each Point. Thofe who would project 

 a if'ield in a fourth Part of the Compafs by 

 which it might be laid down by the aforefaid 

 Scale, may lay the other Edge of it before 

 them, where they may fee the five former 

 Divifions divided into 10, and at the End one 

 of them Decimally divided, as one of the 

 other was . For Example, If you would take 

 the Dillance of 7 Chains, 52 Links, extend 

 the Compalles from the Point where the 2d 

 Line interfefts the 7th, to the Point where 

 the Line denoting 50 is interfered by the faid 

 7th Line* This appears plainer ftill by the 

 Dots. 



Fig. 2.3 There are alfo other Lines of 

 equal Parts, which may be us*d in Surveying, 

 zsFig. 2 ^ One of them is divided into 180 

 Parts, and has before it a Part Decimally divi- 

 ded ; and it is ligur'd 30, intimating that 50 

 of thofe Decimal Parts are equal to an Inch.
