--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. [Illustration: FIG. 243.] At this point you may work in any comic story of houses in a Western tornado, which, under a stress of weather are not stationary, but seem inclined to change their base and even to fly, etc. Fig. 243 shows how a man becomes a stationary object when the line AB divides him in the centre. Motion. But when you slant the AB lines they suggest motion (Figs. 224, 225, and 226). [Illustration: FIG. 244.] Although the pyramid is the emblem of stability, when resting upon its base--with the AB line dividing it in the centre--if you take the same form and point the apex in any other direction it immediately suggests motion, as in Figs. 227, 228, and 229. [Illustration: FIG. 245.] Not only does it suggest motion, but it tells the direction of the movement suggested. Any child can tell in which direction the arrow and the ducks are flying. There is Another Meaning to this figure. It is a wedge, and means cleaving--entering into--(Figs. 230, 231, 232, and 233). But when one views it from the opposite direction the meaning is just the opposite to a wedge. It now means reception (Fig. 234). The mouse is entering and the alligator is receiving. Draw All Your Figures as Large as the Paper Will Permit you to make them; otherwise the audience, or some persons in the back part of the audience, will miss part of your talk, and that will spoil their enjoyment and diminish your applause. Upon a new sheet of paper draw a horizontal line (Fig. 235), and explain that This Line Means Repose. It is the position a person assumes in sleep; it is the surface of the ocean during a calm (Fig. 236). Here we again have the upright line AB (of Fig. 220), in the mast of the becalmed and immovable ship of Fig. 236. When a squall comes up not only does AB change to a diagonal line (Fig. 237), but the horizontal line, indicating repose, is broken into a series of irregular points, showing noise, movement, and commotion. Figs. 238 and 239 show the same effect of lines. Something Which Needs Practice, is the ape; but when you draw it carefully a few times and then practise on it, as you would upon a difficult feat in skating, or any other sport, you can learn to draw the thing in less than a minute. The Evolution of the Ape is its growth from a few simple lines. First draw Fig. 240, then add a curved line to the top of the first figure and some wiggles to the bottom (Fig. 241).
