undreds of special instructors are now employed in training
young people in the theory and practice of physical exercise. These expert
teachers, to do their work with thoroughness and discipline, recognize the
necessity of looking after the daily living of their students. The time of
rising and retiring, the hours of sleep, the dress, the care of the diet,
and many other details of personal health become an important part of the
training.

Recognizing the fact that alcoholic drink and tobacco are so disastrous to
efficiency in any system of physical training, these instructors rigidly
forbid the use of these drugs under all circumstances. While this
principle is perhaps more rigorously enforced in training for athletic
contests, it applies equally to those who have in view only the
maintenance of health.

Books on Physical Education. There are many excellent books on
physical education, which are easily obtained for reading or for
reference. Among these one of the most useful and suggestive is Blackie's
well-known book, "How to Get Strong and how to Stay so." This little book
is full of kindly advice and practical suggestions to those who may wish
to begin to practice health exercises at home with inexpensive apparatus.
For more advanced work, Lagrange's "Physiology of Bodily Exercise" and the
Introduction to Maclaren's "Physical Education" may be consulted. A
notable article on "Physical Training" by Joseph H. Sears, an Ex-Captain
of the Harvard Football Team, may be found in Roosevelt's "In Sickness and
in Health."

Price lists and catalogues of all kinds of gymnastic apparatus are easily
obtained on application to firms handling such goods.

Various Systems of Physical Exercises. The recent revival of popular
interest in physical education has done much to call the attention of the
public to the usefulness and importance of a more thorough and systematic
use of physical exercises, both at home and in the schools. It is not
within the scope of this book to describe the various systems of gymnastic
and calisthenic exercises now in common use in this country. For the most
part they have been modified and rearranged from other sources, notably
from the two great systems, i.e., Swedish and German.

For a most comprehensive work on the Swedish system, the teacher is
referred to the "Swedish System of Educational Gymnastics," with 264
illustrations, by Baron Nils Posse. There is also a small manual for
teachers, called
