as you feel thirsty; but
avoid large draughts of _cold_ water when you are heated or are
perspiring, and never drink enough to make yourself logy. You are apt to
break these rules on the first day in the open air, and after eating
highly salted food. You can often satisfy your thirst with simply
rinsing the mouth. You may have read quite different advice[8] from
this, which applies to those who travel far from home, and whose daily
changes bring them to water materially different from that of the day
before.

It is well to have a lemon in the haversack or pocket: a drop or two of
lemon-juice is a great help at times; but there is really nothing which
will quench the thirst that comes the first few days of living in the
open air. Until you become accustomed to the change, and the fever has
gone down, you should try to avoid drinking in a way that may prove
injurious. Base-ball players stir a little oatmeal in the water they
drink while playing, and it is said they receive a healthy stimulus
thereby.

Bathing is not recommended while upon the march, if one is fatigued or
has much farther to go. This seems to be good counsel, but I do advise a
good scrubbing near the close of the day; and most people will get
relief by frequently washing the face, hands, neck, arms, and breast,
when dusty or heated, although this is one of the things we used to hear
cried down in the army as hurtful. It probably is so to some people: if
it hurts you, quit it.

FOOT-SORENESS AND CHAFING.

After you have marched one day in the sun, your face, neck, and hands
will be sunburnt, your feet sore, perhaps blistered, your limbs may be
chafed; and when you wake up on the morning of the second day, after an
almost sleepless night, you will feel as if you had been "dragged
through seven cities."

I am not aware that there is any preventive of sunburn for skins that
are tender. A hat is better to wear than a cap, but you will burn under
either. Oil or salve on the exposed parts, applied before marching, will
prevent some of the fire; and in a few days, if you keep in the open air
all the time, it will cease to be annoying.

To prevent foot-soreness, which is really the greatest bodily trouble
you will have to contend with, you must have good shoes as already
advised. You must wash your feet at least once a day, and oftener if
they feel the need of it. The great preventive of foot-soreness is to
have the feet, toes, and ankles covered with oi
