conditions point to change of garments when camp is made. We always
change our clothes when we get wet in the city. So for years I carried
those extra nether garments--and continued in the natural exposure to
sun and wind and camp-fire to dry off before change time, or to hang
the damp clothes from the ridge-pole for resumption in the morning. And
then one day the web of that particular convention broke. We change wet
trousers in the town; we do not in the woods. The extras were relegated
to pile number three, and my pack, already apparently down to a
minimum, lost a few pounds more.

You will want a hat, a _good_ hat to turn rain, with a medium
brim. If you are wise, you will get it too small for your head, and rip
out the lining. The felt will cling tenaciously to your hair, so that
you will find the snatches of the brush and the wind generally
unavailing.

By way of undergarments wear woollen. Buy winter weights even for
midsummer. In travelling with a pack a man is going to sweat in
streams, no matter what he puts on or takes off, and the thick garment
will be found no more oppressive than the thin. And then in the cool of
the woods or of the evening he avoids a chill. And he can plunge into
the coldest water with impunity, sure that ten minutes of the air will
dry him fairly well. Until you have shivered in clammy cotton, you
cannot realize the importance of this point. Ten minutes of cotton
underwear in cold water will chill. On the other hand, suitably clothed
in wool, I have waded the ice water of north country streams when the
thermometer was so low I could see my breath in the air, without other
discomfort than a cold ring around my legs to mark the surface of the
water, and a slight numbness in my feet when I emerged. Therefore, even
in hot weather, wear heavy wool. It is the most comfortable.
