Example.
402 divided by 21, gives in the Quotient 19 and 3 over; so then, you may draw this Draft on this Paper, which is 21 Inches, by a Scale of one Inch divided into 19 parts.
〈 math 〉〈 math 〉But if it be a sheet of ordinary Paper, of 16 Inches long, and you would draw the same Draft on it, though in a less Form, then di∣vide 402 by 16.
〈 math 〉〈 math 〉So that for a sheet of 16 Inches long, a Scale of one Inch divided into 25 parts, will serve to draw your Draft by on such a Paper.
But if it be required to draw the Draft of a Garden, or the like, on a quarter of a sheet of Paper, then observe the ensuing Directions.
