Mechanick exercises : or, The doctrine of handy-works ; applied to the

arts of smithing, joinery, carpentry, turning, bricklayery ; to which is

added, Mechanick dyalling: shewing how to draw a true sun-dyal on

any given plane, however scituated ; only with the help of a straight

ruler and a pair of compasses, and without any arithmetical calculation.

/ by Joseph Moxon.
