secutive order (Fig.268). Then let CD represent 12 yards (this would be enteredto the right-hand side of 8, because 8 represents the position ofC), and let EF = 9 yards (this would be entered to the left of18, the figure corresponding to F). From these figures we coulddraw a plan of the piece of… … Fis. 269. Fiff. 270. This plan is plotted to a scale of i of an inch to 10 yards inKg. 270. Suppose we wish to make the plan in its greatest dimensions6 inches long, we must first construct a scale of yards.
