sun. A fair idea may also be gained of the time of day by the length of
shadows, if you remember that shadows are long in the morning and
continue to grow shorter until midday, when they again begin to
lengthen, growing longer and longer until night.

To find the direction of the sun on a cloudy day, hold a flat splinter
or your knife blade vertically, so that it is absolutely straight up and
down. Place the point of the blade on your thumb-nail, watch-case, or
other glossy surface; then turn the knife or splinter around until the
full shadow of the flat of blade or splinter falls on the bright
surface, telling the location of the sun.

An open spot where the sun can cast a clear shadow, and an hour when the
sun is not immediately overhead, will give best results.


=Wind=

The wind generally blows in the same direction all day, and if you learn
to understand its ways, the wind will help you keep the right trail.
Make a practise of testing the direction of the wind every morning.
Notice the leaves on bush and tree, in what direction they move. Place a
few bits of paper on your open hand and watch in which way the wind
carries them; if there is no paper, try the test with dry leaves, grass,
or anything light and easily carried by the breeze. Smoke will also show
the direction of the wind.

When the wind is very faint, put your finger in your mouth, wet it on
all sides, and hold it up; the side on which the wind blows will feel
cool and tell from what quarter the wind comes: if on the east side of
