nterest, 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.

SCIENCE _for_ BEGINNERS

_By_ DELOS FALL

_Professor of Chemistry, Albion College_

To supply the need for a course that will give the preparatory
training which any scientific study demands, SCIENCE FOR BEGINNERS
by Professor Delos Fall was made. The aim in this text is to win
the interest of pupils, to give them conceptions of nature that are
fundamental, and above all to ground them in the method of science.

The subject matter has to do with the earth sciences, and principally
with physics and chemistry. In the development of each topic, every
advantage that the pupils' experience and interest may afford is
utilized. Exercises or experiments are interspersed throughout the
work, and for these only the simplest materials are required. The
studies are carried to those connecting principles which permit the
organization of knowledge. The book is illustrated with a number of
excellent photographs and over 200 drawings of more than usual merit.

The text is adapted _for use in grades seven, eight, and nine_, or in
any classes that are about to take up their first work in science. It
will prove helpful to the teachers and pupils who use it directly,
and its influence will continue with classes as they advance. It will
thoroughly ground pupils in those ideas that are prerequisite to any
right work in science.
