Two Mental Operations
There are two distinct operations in this method. First the Imagination takes the two objects and determines how they shall be arranged; what they shall do; or how they are to look in the picture. Second, the mind's eye photographs the picture so arranged by the imagination. The impression is made upon the brain when the picture is photographed. You may decide upon a good combination of the objects, but if you do not SEE the picture you will not remember. The impression is made upon the brain when the mind's eye actually sees the picture which your Imagination has constructed. Just as the photographer first arranges his group in the manner that he thinks will make the best effect, then presses the bulb and exposes the plate. If he only arranged the group and did not expose the plate he would have no picture, and so, if you imagine the picture and do not SEE it, you will have poor memory.
