of your perspiration. This, in turn, helps maintain your normal 
body temperature, and helps to keep you from overheating. 
Your feet are your only means of reaching safety, so take care 
of them. Keep sand out of your shoes, even if it means frequent 
stops. Spiral puttees overlapping the top of the shoes help to 
keep sand out. If your shoes are thin wear two pairs of socks 
if possible. 
HOW TO TRAVEL 
If you think you may be found where you are, stay there. 
Otherwise travel at night and do not try for too great speed. 
Remember the marathon runner. He conserves his strength 
for distance and does not try to sprint. In the daytime rest 
quietly, covered from the sun by shade, if any, or by a make- 
shift blanket. If you have a compass, trust it rather than 
yourself. If you do not have one, never forget the importance 
of keeping on a straight path. When resting, always sit facing 
the direction you want to go. When lying down have your head 
in that direction, so that you won’t forget which way you were 
going. Or arrange a stick or a line of pebbles as a pointer. 
SIGNALS 
If you have matches and any burnable material, make a bright 
fire as a signal at night, or a smoky smudge as a signal in the 
daytime. If you have gasoline, you can scratch large letters 
in the sand, fill these trench-like lines with gasoline and ignite 
when planes pass overhead.
