ON THE VALUE OF A MAP. Experiment XVII. For this experiment the private student needs the assistance of a friend who will act as experimenter while he is the subject. Below are given two pieces of imaginary " history." Piece A is to be read out by the experimenter to the subject (or to a class).

Now Questions B must be answered. Historical Piece A. In the first year of the reign of William X., of Zamboo, A.d. 2100, a revolt occurred among his subjects living among the hills of Banah.
