In absence Of figures this would seem
almost incredible. Is it a wonder now
that she was triedl In view of this lat.
ter estimate Of nervous power expended
in walking, is It advisable or beneficial
for feeble persons to indulge in long
walks ''as an exercise" for the regain
of strength and health, and does 1t not
account for the fatigue so soon felt by
such persons9 A moderate, short walk,
with occasional rests, or riding would
be better for them. Furthermore, this
Is not all the power expended during the
day. For the vital organs, the stomach,
lungs, respiratory muscles, liver, etc. ,
and every vital process consumed the
nervous power. The brain, which was
considerably exercised in mental activity
in guiding the work, is a great con-
sumner of nervous force. So that, taking
all together, the sewing woman had a
very exhaustive days work.
1t is worthy of note here that the
human complex machine, like all other
machinery, requires and consumes an
amount of power commensurate with
the work done, and there is no evading
this law nor the penalty of its violation.
A sewing machine operated by the foot
is more exhaustive, in equal time, than
hand sewing, because it does more work.
1t takes power from the spinal nervous
axis down the nerves of the leg. the
power SO used being loss to the body,
and tending specially to weaken the
organs and ligaments of the pelvis. The
ordinary hand sewing, which is herein
shown to be very exhaustive of power,
usually effects weakening of the
digestive organs, lungs and muscles of
the chest.
1t may be questioned by some, eff
exercise is so exhaustive of nervous
force and so fatiguing, how can it con-
duce to make person stronger This
is a very natural query, and it may be
thus answered: Exercise will strengthen
the body only by conforming to certain
AoV . &Ase SoAAACAOuos VA, Iuotly, III IC-
gard to power. In this the law of sup
ply and consumption must be observed,
which requires that the amount OF nerv-
Gus power acquired each day as result
or product of food digested and air in
spired, must be more than the power
expended in bodily activity. Food
and the air are the only sources of
bodily substance and power; the ele-
ment of air being quite as essential as
that of food. Secondly, in regard to
exercise ITSELF Herein three laws, must
be recognized: First, all the muscles
must act together, as nearly as possible,
in simultaneous cooperation move
ment, SO that none gain strength to the
disparity of others which are inactive;
second, such cooperative exercise must
be taken with gradual increase of bur-
den imposed, and of effort applied from
time to time as the body gains general
strength; third, the time given to such
exercise should be brief, with longer in
tervals for rest and growth and the or
binary pursuits Of life.
