How im perative this is in speaking to children, a very little expe rience will show. But in fact it is just as imperative in addressing adults of any grade of maturity and culture. Adults, especially persons of culture, can grasp more com plex ideas, and their attention can therefore be held longer within a given field; but all the time it will be moving from one to another aspect of this group of related objects or ideas.
