remember. (See pp. 92, 97.)

3. If we increase the number of connections for facts, we are more
likely to remember them. It is largely for this reason that history
should be taught with correlated subjects, such as geography,
literature, science (inventions), etc. For example, the story of the
Spanish Armada is remembered better if we have read _Westward Ho!_ and
the story of the Renaissance is made clearer and is therefore remembered
better, if we connect with it the inventions of printing, gunpowder, and
the mariner's compass. (See p. 121.)

4. Repetition is necessary to memory. Facts or groups of facts must be
repeated to be remembered. This is the purpose of the drills which are
necessary to good teaching, but are only a part of it. Reviews are not
to be considered merely as repetitions, but should be treated more as
aids to better understanding. (See p. 31.)




CHAPTER III

CORRELATION OF SUBJECTS


HISTORY AND GEOGRAPHY

These subjects are very intimately related, and each should be used in
teaching the other. Geography, which is often called one of the "eyes of
history," may be used in the teaching of this subject in two ways. In
