B, B, B, &c.—Twelve fpokes, one’ end of each 
inferted in the ftock, and the other faftened with a 
{crew to the outward ring, or periphery of the wheel. 
C.—Periphery; an iron ring 164 feet, or one pole 
in circumference, adapted to Gunter’s concife me- 
thod of arithmetick, and divided into 25 equal 
parts, correfponding to the links of his chain for 
land-meafuring, &c. 
D, D, D, &c.—Twelve fmall plates, denoting the

faft into the {tock of the wheel, and when at work, 
revolves with it. 
F.—A ftyle or alidade, being an expanding fcrew-

fequently four of them a chain; the ftyle, hanging 
pendant, and moving to its proper figure, denotes 
the length of ground paffed over, as divided into 
chains and poles, on the index of the axis E. and
