t out fresh air. Clothes should not be too heavy nor
too tight. Shoes should have soles straight on the inner side, and be
broad enough to allow the toes full play, and have low heels. Shoes that
are comfortable to hike in are apt to be the best for all the time wear.

At night the clothes worn during the day should be aired and dried
thoroughly. This will help much in maintaining the right body
temperature, because clothes become damp from wearing, and dampness uses
up body heat.

_Sunlight_--Sunlight is one of the best health bringers known. Little
children--and grown people, too--suffering from the most serious forms
of tuberculosis, that of the bones, get well if they are kept in the
sunlight. In one of the finest hospitals for children in the world, in
Switzerland, the main treatment is to have the children play outdoors
without clothes in the sunlight, and they do this even when there is
heavy winter snow on the ground. Human beings droop and die without the
sun, just as plants do, though it takes longer to kill them. It is a
gloomy person who does not feel happier in the sun, and a happy and
cheerful person is generally healthy. So get into the sun whenever you
can. Walk on the sunny side of the street, and open your windows to the
sun whenever you can. However, in hot climates and in the warmest summer
days, remember that the sun can injure as well as help, and do not
expose the head or body unnecessarily.

_Water_--As about three-quarters of our body weight is water, the solid
portions of bone, muscle, and so forth, constituting only one-quarter,
and as considerable water is given off each day by evaporation from skin
and lungs and with excreta, the loss must be made up. In addition to the
water taken with meals and contained in the food a Girl Scout should
drink at least six tumblers of water daily. This is a quart and a half.
One glass should be taken on arising and before breakfast, two between
breakfast and lunch, two between lunch and dinner, and one before going
to bed. Be sure the water is pure, and boil any water the purity of
which is doubted in the slightest. Water kept cool in the ice chest, or
in a jar with a moist cover, is better than ice water, both because cool
water actually quenches thirst more easily, being more readily absorbed
than ice cold water, and because it is difficult to control the purity
of ice.

_Food_--Food should be clean and kept clean. Growing girls can tell
whether they a
