Collecting birds' eggs should be condemned, because it nearly always
leads to the robbing of the nests. The practice of exchanging eggs is
the chief cause of this; for although an occasional boy will collect
wisely, the greater number are simply anxious to add to their collection
without regard for the sacredness of the birds' homes.

A collection of birds' nests may be made after the nests have been
abandoned for the season, and it will be found useful for interesting
the pupils in the ingenuity, neatness, and instinctive foresight of the
builders.

INSECTS

There are three classes of insects that are of immediate interest to the
pupils of the Junior Grades, and the teacher who makes direct use of
this natural interest has taken possession of the key to success in
insect study in the primary classes.

The three classes, basing the classification upon their power to attract
attention, are:

The beautiful insects, including moths, butterflies, and beetles,

The wonderful insects, including such insects as ants, ant-lions,
caddice-flies, etc.,

The economic insects, including bees, silk-worms, codling-moths, etc.

Economic insects are interesting because of their relations to the
occupations of the home. The successful growing of farm, orchard, and
garden crops practically depends upon keeping a proper balance of insect
and bird life.

The teacher who feels that his knowledge of insects is too limited to
allow him to undertake the teaching of this branch of Nature Study
should cast his misgivings aside; for it is not difficult for the
teacher who knows nothing about insects at the outset to become
acquainted with such members of the three classes named above as attract
the attention of the pupils of the Nature Study
