e together, what they
feed on and the various other questions which the inquisitive mind of a
healthy child will ask. When field work is not possible, gather the
insects and keep them alive in jars where they can be fed and observed.
Some forms cannot be kept in confinement and in such cases samples
should be killed and pinned, thereby forming a collection for study.

Most of the forms which are included in the following chapters can be
kept in confinement in glass jars or studies out doors. The studies have
been made so general that in case the particular form mentioned is not
available any closely related form can be used. Each child should make a
small collection of living and pinned insects for study and should be
encouraged to observe insects and their work in the field. The
collections and many of the observations could be made to good advantage
during the summer vacation when the insects are most abundant and
active.

Pupils should not be encouraged merely to make observations, but they
should be required to record them as well. Brief descriptions of the
appearance and development of insects, the injury they do, and remedies
for the same, will help fix in mind facts which otherwise might soon be
forgotten. Drawings, whenever possible, should also be required. The
pupil who can record observations accurately with drawings will not soon
forget them. The teacher should therefore require each pupil to provide
himself with a note-book for keeping brief, but accurate notes and
careful drawings. The drawings should be made with a hard lead pencil on
un-ruled paper, the size of the note-book, and the pupils should be
encouraged to be neat and accurate.

The author wishes to take this opportunity of expressing his deep
appreciation for the many helpful suggestions and other assistance which
Mr. R. H. Emberson, superintendent of Boys and Girls Club Work in
Missouri, has given. It was his life-long devotion to the boys and girls
of the grade schools and his keen appreciation of their needs that lead
him first to suggest to the author the importance of preparing this
little book for their use.

"_The study of entomology is one of the most fascinating of
pursuits. It takes its votaries into the treasure-houses of Nature,
and explains some of the wonderful series of links which form the
