Figs. 240-242

AB conveys the idea of

A Stationary Object

—a telegraph pole, a tree, a church steeple, etc. If there is one idea which it does not suggest, that idea is motion.

Draw two lines diagonally down from A to the base line (Fig. 221), and point out that this represents a pyramid, which when resting upon its base is the

Emblem of Stability.

Upon another sheet of paper draw two AB lines, and joining them at the top (Fig. 222), show that these lines still represent a stationary object—a house.
