[illustration]

BEcause the effect of this Ru∣ler is aboue declared by Ta∣bles, an Instrument also wel knowen and commune amonge good Artifycers: I will not spende many woordes, in opening it. Be∣holde the fygures, and learne by them howe ye ought to make, and commonly to decke youre Ruler, bothe with Tymber and bourde measure.

Ensample.

ADmit the ruler to be. a. b. c. d. wel playned, twelue In∣ches longe, a quarter of an Inche thicke, and two Inches yn breadth. Truly yt were more com∣modious, if it hath two foote in length. This ruler here imagined but a fote in length, is diuided fyrst in twelue euen partes, called In∣chess: then euery Inche in halfe, or two equall porciōs: ech half in two quarters: euery quarter in four or two partes at the lest: as in this en sample. Then are the fygures pla∣ced from. 1. to. 12. manifestinge the ynches. Thus your Ruler is ready to receaue the measures which are marked or fygured on your Ruler thus. And fyrst the Tymber mea∣sure as foloweth.

YE shall resorte to youre Table of Tymber measure, and seeke howe many fete belonge to. 1. Inche square: there ye shall fynde. 144. This number note write, or rather graue, where this fygure. 1. representinge one inche, is fygured: as pe may se in the middes betwene the lyne. e. f. and the line of the fygure. g. h. This done. resorte to your Table agayne, and beholde howe many fote and par∣tes. 2. Inches square requireth. So shall ye fynde. 36. foote, whiche is placed in the next roume leftwarde, vnder the charactere. 2. sygnify∣ing two ynches. Thus of the reste, fete, Inches, and partes, founde in youre Table, vntyll you come to the. 12. Inche, where ye shall per∣ceyue. 12. Inches onely to be set in his proper roume. &c. Then seeke further in your Table, what belongeth to. 13. Inches: Lo. 10. ynches and. 1/5. This muste be numbred in the lyne. c. a. from c which lyne be∣tokeneth the thicknes of the Ruler. Make there a little stryke vpon that grosnes, euen or ryght agaynst the measure. 10. 1/5. what nede many woordes. Thus do vntyll ye come to. 36. Inches, and and that is noted (as the Table of Tymber measure she∣weth (right with. 1. ynche, and .3/3. from c. No other∣wyse is perfourmed of borde measure, as ye maye beholde set forthe by the helpe of his proper Table in the square rou∣mes, beneath the line. e. f. and also in the other thick∣nes or lyne b. d.
