can see any distance, climb that and get an outlook. You may be able to
see the smoke of your camp-fire, which, after all, cannot be so far
away. You may find a landmark that you do remember. If you see nothing
which you can recognize, make a signal flag of your handkerchief and put
it up high, as high as you can. Your friends will be looking for that.
Then give the lost signal, one long blast with your whistle, and after a
short pause follow with two more blasts in quick succession. If you have
no whistle shout, loud and long, then wait a while, keeping eyes and
ears open to see and hear answering signals. If there is none, again
shout the lost signal and continue the calls every little while for
quite a time. Another call for help is the ascending smoke of three
fires. This, of course, is for daylight. Build your fires some distance
apart, twenty-five feet or more, that the smoke from each may be clearly
seen alone, not mingled with the rest. Aim to create _smoke_ rather than
flame; a slender column of smoke can be seen a long distance, therefore
the fire need not be large. Choose for your fires as clear a space and
as high an elevation as can be found, and in the relief and excitement
of rescue _do not forget to extinguish every spark_ before leaving the
ground.

If you decide to keep moving, blaze your trail as you go, so that it may
be followed and also that you may know if you cross it again yourself.
You can blaze the trail by breaking or bending small branches on trees
and bushes, or by small strips torn from your handkerchief and tied
conspicuously on twigs. If you are where there are no trees or
undergrowth, build small piles of stones or little hills of earth at
intervals to mark your trail.

If night overtakes you, look for the _North Star_. That will help if you
know at what point of the compass your camp lies, and if you remember
