vegetables like tomatoes, lettuce, water
cress and an occasional potato, for these
last supply certain salts derived from the
earth, necessary for the publication of
the blood; while surplus of al5uminous
food, while it will serve the purposes of
keeping him warm and active, throws
upon the kidneys great deal more than
their share of work, and therefore tends
9 weaken them, and through them the
whole system. So much for preparatory
diet. as
NOW FOR EXERCISE
necessary to keep the muscles IN proper
condition and work of the food witch
supplies muscular energy.
Obviously that form of exercise which
attacks the largest number of muscles is
the most desirable. But, before proceed
ing to discuss the forms of exercise most
profitable, word should be said as to
the effect of exercise. Most important
are the effects upon the heart ana lungs
and their subsidiary agents. The system
requires that great deal of oxygen
should be taken into the lungs and thus
to the blood, in order first to burn up the
carbon and supply heat, and to carry off
the carbonic acid formed by this combus-
ton. Free, full and copious respiration
is needed; and exercise, by increasing
the rapidity of the circulation, increases
proportionately the amount of air respir-
ed. Thus exercise serves to purify the
blood of carbonic acid as we'll as to sup
ply the proper heat for the body. So
long as the power of maintaining strong
ano rapid respiration continues, sufficient
oxygen is drawn into the body, and
sufficient cal bonic acid is drawn out, but
when this power fails the carbonic acid
accumulates in the blood and produces
breathlessness. This is brought about
mechanically. The blood vessels which
convey the blood through the lungs are
choked up having more blood forced into
them than they can carry; the blood &C
cumulates IN the right side of the heart
and impure blood, laden with carbonic
acid, is pumped back into the system.
Still another danger raises from too vio-
lent exercise before the arteries learn to
accommodate themselves to the increased
demand upon them,and that's citation of
the cavities, which give way before the
strain and induce chronic disease. Hence,
when persons of sedentary pursuits
take sudden and violent exercise thew
endanger their health in very serious
degree. Those who begin to mend their
lazy habits must do so slowly, gradually
accustoming the arteries to do more
work, and thus preventing heart disease.
No man who has worked like machine
for years is in condition to run any dis.
lance at full speed and should not at
temptit. His exercise should be confined
to brisk walk to begin with, and he
should avoid anything like serious con-
dition of breathlessness. After the prop
er condition is arrived at, his digestive
system will be enormously improved.
and Lis whole body will begin to glow
with health and animation.
EXERCISE FOR CHILDREN.
Exercise is Instructive with children,
and, should be encouraged. Children,
when they have reached the age of three
years, should be allowed to play as much
as they like, and the hoops and balls, for
which they have an instructive partially,
are better than any gymanastic course
they can go through. The German sys-
tenn of gymnasia for boys is not advocat-
eG IN the volume before US. The games
which boys also take 10 are the most
beneficial exercise that can be found for
them. Swinging, for instance, judici-
ously allowed, exercise in a profitable
degree all the muscles of the body, and
like football, shiny, leaping, running,
wrestling, boxing, and So forth, are better
than anything OF aA artificial character.
The gymnasium is all very we'll in its way,
but the game is very much better. :,
There is one subject which the scientific
gentlemen who are publishing the health
primers lay great stress upon, and that is
the injury done to young lads by the
athletic contests which have, during the
past twenty years, found so much favor
in the English, public schools. A table
of growth, based upon careful observa-
ton of 1906 boys of ages ranging from
ID to II shows that the development of
the human male body is greatest between
10 and II, reaching its maximum at about
the 10th year. Thus the period of boys
life between Is and II becomes one of
great consequences to him, and if he he
at such a season subjected to great strain
--as he undoubtedly is, both Intellectual
~ and physically, where athletic contests
are encouraged-his development must
suffer, and either his future growth will
be interfered with or the foundation will
be laid of constitutional disease.
GIRLS AT GAMES.
Girls up to eight or nine years are
allowed to play the same games as their
brothers. and generally beat them, but,
after that time, preposterous notions of
department begin to dwarf them. Corsets
and tight shoes cripple their bodies, and
exercise ceases. The muscles dwindle
and waste, and the whole CHASTITY process
sion of feminine ills begin to appear. Of
course 1t is not to be expected that they
should play violent games, like football
or cricket, but tives, rackets, base ball
of the feminine order LAWN tennis, row.
ing, riding and swimming ought to be
INDUCED in by girls as we'll as boys.
Where these opportunities are denied
them, they should be given the privilege
of the gymnasium.
Boys games may be safely played by
grown men, up to forty, when changes
begin to take place in the body which
render exercise likely to throw a great
strain upon the heart and blood-vessels
