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.
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.
