[This chapter is taken in full from a work on
ornithology, written by Dr. Coues of the
Smithsonian Institution. It is the advice of an
accomplished naturalist and sportsman to his
fellow-naturalists, but is equally adapted to the
young camper. Hardly any one can write more
understandingly on the subjects here presented
than the doctor, who has had long experience with
the army, both in the field and garrison, and is
an enthusiastic student of natural history
besides. The remarks upon alcoholic stimulants are
especially recommended to the reader, coming as
they do from an army officer, and not a temperance
reformer.
