d adventure, no history, nothing of a patriotic nature and no drama.
On the other hand (reading across), there are many fables in the first
volume, a few in the second but none thereafter; a few myths and some
classic literature are found in the first three volumes, more in the
fourth and fifth, but the number and quantity decrease in the sixth and
do not appear thereafter; nature work is to be found in all the volumes
but is strongest in the seventh; drama appears in the eighth and the
ninth. Biography has a place in all volumes, but is strongest in the
seventh; while the Studies, appearing in all volumes, reach their
highest point in the tenth.

_3. The Studies and Helps_

As has been said, the chief factors in making _Journeys Through
Bookland_ unique and of greatest value are the many helps that are given
the readers, young and old. These helps are varied in character and are
widely distributed through the volumes. They must be considered one at a
time by the person who would assist others to use them to the best
purpose. These helps consist of what are technically known as studies,
notes, introductory notes, biographies, pronouncing vocabularies,
pictures, tables of contents and index. The following comments will make
clear the purpose of each.
