TREES, STARS _and_ BIRDS
A BOOK OF OUTDOOR SCIENCE
By EDWIN LINCOLN MOSELEY
_Head of the Science Department, State Normal College of Northwestern
Ohio_
The usefulness of nature study in the schools has been seriously limited
by the lack of a suitable textbook. It is to meet this need that _Trees,
Stars, and Birds_ is issued. The author is one of the most successful
teachers of outdoor science in this country. He believes in field
excursions, and his text is designed to help teachers and pupils in the
inquiries that they will make for themselves.
The text deals with three phases of outdoor science that have a
perennial interest, and it will make the benefit of the author's long
and successful experience available to younger teachers.
The first section deals with trees, and the discussion of maples is
typical: the student is reminded that he has eaten maple sugar; there is
an interesting account of its production; the fact is brought out that
the sugar is really made in the leaves. The stars and planets that all
should know are told about simply and clearly. The birds commonly met
with are considered, and their habits of feeding and nesting are
described. Pertinent questions are scattered throughout each section.
The book is illustrated with 167 photographs, 69 drawings, 9 star maps,
and with 16 color plates of 58 birds, from paintings by Louis Agassiz
Fuertes.
It is well adapted for use in junior high schools, yet the presentation
is simple enough for pupils in the sixth grade.
