e work, like sewing or reading, look up and "at nothing" every
once in a while.

The following are some important rules to remember in saving your eyes:

Rest your "near" eye muscles by looking at distant objects and places.

Do not work facing a light or where the rays from a light cross your
field of vision directly.

Work so far as possible by indirect or reflected light.

If you must work near uncovered artificial lights, wear an eye-shade.

When sewing or writing have the light at your left, unless you are
left-handed. This is to keep the shadow of your hands from the work.

Avoid a glare or light that is in streaks or bars of alternate dark and
bright. Diffused, even light is best.

Have your eyes examined by a competent oculist immediately:

If you have headaches,

If the eyes sting or burn after using,

If print or other objects dance or blur,

If you must get close to your work to see it,

If near work tires your eyes or you,

If there is the slightest irritation or soreness
about the lids or other parts.

How to Avoid Muscle Strain

Girls and women in attempting to live an outdoor life or indeed when
trying to do many of the things numbered among the Scout activities,
such as First Aid, Home Nursing and Hiking, often give themselves quite
unnecessary pain and fatigue from lifting, pulling and carrying weights
in the wrong way. Ability to carry and lift or move is not so much
dependent upon absolute strength as it is on knowing how. The whole
body, so far as it is a physical mechanism, may be thought of as a
series of levers, of which the muscles, bones, and joints make up the
parts and are fulcrum, power arm or weight arm as the case may be.
Without going into the details of bodily structure or even knowing the
names of the different bones and muscles, it is possible to learn a few
simple things about the right use of these levers that will be useful at
all times.

Certain parts of the body are more able to do heavy work than others,
and the first thing to remember is that the upper part of the back, the
shoulders and the upper arms are stronger than the lower back, the
abdomen and the lower arms. Therefore, whenever you are trying to lift
or move an object, see if you cannot use these stronger parts. If the
arms are held away from the body when lifting, pulling, throwing or
pushing, the muscles of the upper arm, the sh
