is essential to a tournament player.

Regular hours of sleep, and regular, hearty food at regular hours
are necessary to keep the body at its highest efficiency. Food is
particularly important. Eat well, but do not over-eat,
particularly immediately before playing. I believe in a large
hearty breakfast on the day of a big match. This should be taken
by nine-thirty. A moderate lunch at about one o'clock if playing
at three. Do not eat very rich food at luncheon as it tends to
slow you up on the court. Do not run the risk of indigestion,
which is the worst enemy to dear eyesight. Rich, heavy food
immediately before retiring is bad, as it is apt to make you
"loggy" on the court the next day.

It is certain injury to touch alcoholic drink in any form during
tournament play. Alcohol is a poison that affects the eye, the
mind, and the wind--three essentials in tennis. Tobacco in
moderation does little harm, although it, too, hits eye and wind.
A man who is facing a long season of tournament play should
refrain from either alcohol or tobacco in any form. Excesses of
any kind are bad for physical condition, and should not be
chanced.

Late hours cause sluggishness of mind and body the next day. It
is very dangerous to risk them before a hard match. The moving
pictures immediately before playing tennis are bad, owing to the
eye strain caused by the flicker of the film and the strong light
of the camera. Lead a normal, healthy life, and conserve your
nervous force wherever possible, as you will need it in the hard
matches.
