DR. E. A. ADOLPH TABLE
This table shows how long a man can live with various
amounts of water in various temperatures IN the SHADE and
assuming that he is not physically active.
Its conclusion after much researches are that it is: Better
to renew the water provision of your body every hour.
WATER RATIONING OR NOT?:
STEAD USA Ranger instructions are the same as many Survival
books:
Drink whenever you are thirsty. NO matter the quantity of
water you may have, small or big. RATIONING WILL NOT HELP.
EQUIPMENT NEEDED:
HERE ARE THE ESSENTIALS WHICH YOU NEED IN THE DESERT!:
A few litres of water and a mirror or any other reflecting
object. A compass, a flash light and water. Material that
will project shadow, adequate clothing and more water.
Additional Signalization equipment (flares, etc.) More water once
more and finally food. IN OTHER WORD 4 TIMES MORE WATER.
DESERT TRAVELLING:
If you decide to get on your way do the followings:
1) TRAVEL ONLY AT DUSK, NIGHT AND DAWN.
2) March in direction of the littoral of the sea cost
or toward a known road, a water stream or habitated region.
Along the sea you can find soft water (see water) and
dampen your clothes which will help preserve your body
moisture.
3) Choose the EASIEST road, avoid soft sand and
accidented landscape & follow the trails.
3B) Walk in the hollow of the sand dunes or on their peak
where the terrain is most solid.
4) In most deserts, the river beds end in closed basin or
temporary lakes, don't follow them if you want to reach the
sea.
5) If possible check your road with a map, but realize
that desert maps are relative, not ALWAYS exact because of
the sand shifting the landscape all the time.
6) Do NOT travel when the visibility is bad. Take shelter
during a sand storm. Mark your directions using a stick
deeply stuck in sand, a row of stones or any other means:
use your image-in-nation.
DURING A STORM LAY ON YOUR SIDE, your back to the storm
wind. Cover your face with a cloth and try to sleep.
Don't worry about being covered with sand, it takes years for
sand to cover the rest of camels. If possible seek refuge
near a hill on the opposite side of the wind.
7) Multiply by three your distance estimations. A distance
under evaluation is ALWAYS possible in the desert.
8) Mirages can come up in summer when facing the sun, it
is very difficult to affirm under what conditions and form
they appear.
DESERTS:
One fifth of the earth's land surface is desert. Dry barren
land where survival is Very difficult.
There are all kind of deserts. Their soil can be made of
salt as well as sand.
Some are completely sterile where no plants nor animals can
live, others can feed sheep & camels with a bit of grass and
thorn bushes.
Very hot in the day and very cold at night. These are the
basics of the desert which represent 1/5 of our Earth
surface. There are about 50 deserts in the world.
Deserts occur where air currents which rose at the Equator
and have already shed their moisture descend and are
rewarmed as they near the earth, taking with little local
moisture is present.
There are rarely any clouds to give protection from the sun
or to retain heat at night so that great extremes of
temperature occur form the highest shade temperatures
(58C/136F in the Sahara) to below freezing point at night.
Only small parts of the world's deserts are sand. (About
1/10 of the Sahara) . The greater part is flat gravel cut by
dried up water courses wadis.
The wind has blown the sand away, piling it up in low laying
areas. Elsewhere there may be wind carving mountains, dried
mud-flats & larva flows.
ARID REGIONS:
Most deserts lands were once fertile and some of the
creatures that lived there then adapted to the new conditions.
Like them the survivor MUST learn to make the most of any
available shade to create protection from the sun, reduce
moisture loss and restrict activity to the ends of the day
and the night. Learn from the people who live or travel
through the deserts.
In some deserts especially the Sahara, the deserts of the
Middle East, of Peru & northern Chile and parts of the Goby
deserts in Mongolia there are great temperature differences
between day and night.
At night condensation of any moisture in the air can make
some water available-and in the Nami desert of Southern
Africa fog coming in from the sea often provides for life.
Elsewhere, in such deserts as those of Western Australia,
Northern Mexico & the Mojave of the South-western USA, where
the temperature changes are comparatively slight, there's
very little condensation and consequently both plants and
games are very rare.
Sometimes as in the Kalahari there will be sparse grass &
thorny bushes and even in the most barren conditions, some
kind of life seems to survive, though often invisible if you
don't know where to look
Dust & sand storms may occur at certain times of year
reducing visibility to zero and demanding maximum protection
to prevent sand entering every orifice. Dust devils-desert
whirlwinds like tornadoes are quite common.
When rain does come & in some territories years may pass
with none at all- it may be in torrential down pours which
create flash floods, before being quickly absorbed into the
parched ground.
This provides for a brief blossoming of vegetation & the
emergencies of species such as the Spadefoot Toad of
Arizona for rapid reproduction.
DESERT RAINFALL & TEMPERATURE:
Typical of desert extremes are conditions in the Rub'al
Khali the Empty Quarter, of southern Arabia. For most of the
year there is only a trace of rain but over 30mm may fall on
a single day in the winter.
July temperatures may reach over 48C (120F) dropping to 15C
(60F) at night & December extremes range from 26C to -6.6C
(79-20F)
WATER, FINDING IT IS VITAL:
Water needs are paramount. If you are stranded by mechanical
failure during a planned desert crossing, you will have
plotted your route with an awareness of oases, wells and
water-holes.
Wells can be very deep and the water level requires a
container lowered on a line to reach it.
Small water-holes in wadi bottoms are often seasonal. They
are usually covered with a stone or brushwood.
Away from unknown water-holes, try digging at the lowest
point of the outside bend of a dry stream bed or at the
lowest point between dunes.
DO NOT DIG IN THE HEAT OF THE DAY, THE EXERTION WILL USE UP
TO MUCH FLUID LOSS AGAINST POSSIBLE GAIN.
Exploit cactus and roots as water sources and in deserts
where the day/night temperatures range is great, exploit
this to produce water by condensation.
LIFE EXPECTANCY:
It depends upon the water available and your ability to
protect the body from exposure to the sun to minimise
perspiration. Allow a slight negative balance.
Drink1.5 litre for every 2 litres lost (3-4pt) & then drink
at the rate the body is sweating.
NOTE: THAT THE RATIONING IS USELESS, IT WILL NOT PROLONG
YOUR LIFE EXPECTANCY BY MUCH.
Efficiency is then impaired little and no water is wasted.
Less fluid will not result in less sweating.
Sweating is a cooling mechanism not a way of loosing
moisture. If more fluid is drunk than needed it will be
excreted & used to no purpose.
Without water you will last about 2 1/2 days at 48C (120F)
if you spend the whole time resting in the shade, though
you could last as long as 12 days if the temperature stays
below 21C (70F).
If you are forced to walk to safety the distance you cover
will relate directly to water available.
With none, a temperature of 48C (120F) walking only at
night, resting all day, you could cover 40km (25miles).
Attempting to walk by day you would be lucky to complete 8km
(5miles) before collapse. At the same temperature with
about 2 litres (4pt) of water you might cover 56km (35
miles) and last 3 days.
Your chances aren't appreciably increased until available
water reaches about 4.5 litres (8pt) per person, though
training & determination to survive could contradict
prediction. Miracle still occur
ORAL RE-HYDRATION SALTS:
New technical food survival gadget called oral re-hydration
salts which are widely used in starvation country lately, it
seems that it has recently come out and already saved
thousands of life. Where to get it and what is it???
SHELTER & FIRE:
Make a shelter from the sun and rest in its shade. You'll
also need protection from winds and low night temperatures.
DO NOT stay in a metal vehicle or airplane which may rapidly
become overheated. Use it support a shelter or make use of
the shadow beneath an aircraft's wing.
Make use of rock outcrops and the shadow provided by the
sides of a wadi. Use the double layer techniques to aid
cooling.
In a sand desert you may even be able to use wreckage to
make a shelter beneath the sand. Many desert creatures
spend the day beneath the surface, where the day
temperature is much lower and night much warmer than outside.
Sand will not permit tunnelling and you have to make a
support structure. Having provided immediate shade, build
your shelter in the cool of the evening to conserve energy
and fluids.
Pile rocks to make a windbreak and make use of wadi walls
(except when rain and consequent flash floods seem likely).
If using fabrics, leave the bottom edges lifted and loose by
day to increase air circulation. Weight them down with rocks
at night.
Avoid lying directly on hot ground. If you can; make a
raised bed air can circulate beneath you.
You will need fire for warmth at night and for boiling
water. Smoke will also be very noticeable and useful for
signalling. Desert scrub is dry and burns easily.
If the land is totally barren, vehicle fuel & oil mixed with
sand in a container will burn well (& is an easy way to
light other fires) or use a string wick Camel donkey & other
animal dropping burn well.
DESERT STOVE:
It is not hard to make fire by using this method; take any
metallic container, fill it with sand, imbibe it with oil or
gas & light it with caution.
You MUST make holes in the container to let the air pass in
thus insuring the combustion NEVER add any gas or oil on a
lighted fire. (You'll blow your mind!!!)
DESERT SHELTERS #2:
To survive in the desert, you MUST take shelter from the
sun, the heat and at times sand storm. Here're some
suggestions
1) Cover yourself with sand to protect yourself from the
sun rays and to reduce the perspiration effects. Some
survivors affirm that this sand pressure relax and rest them.
2) If you dispose of a parachute or any other adequate
piece of material, dig a hole, cover it up with the tarp.
2b) MAKE SURE it is well fixed in the ground then crawl
underneath. In proper place put the tarp over rocks or small
mounts.
3) Take advantage of anything that can give you shadow and
shelter. A cave, a tree, a rock or piled up stones done by
others in the past. Along old river beds, valleys, gullies
and ravine one can often find grottos and caves.
4) Whenever possible, use all existing shelters that you find.
5) Don't forget to leave some opening to let air circulate.
6) Beside water, and signal, shelter is next in line, so if
you have crashed, stay close to the plane once assured that
there is no fire hazard.
Don't stay in it during the day, it is as hot as an oven,
yet at night it can be used to protect from the cold. During
the day, make a pent-roof with a parachute which you install
over a wing, leaving at least 2 feet of free space under the
pent-roof to permit the air to circulate.
MAKE SURE that the plane is well attached and that there is
no risk that it will crush or cave in, if there is a sand
storm or big wind.
CLOTHING:
It helps reduce fluid loss and gives protection from sunburn
as well as warmth at night and a barrier against insect
bites and thorns.
In the desert it should be light and loose fitting with air
space between the garments and the body to provide
insulation. Copy the flowing, layered garments of the Arab
world.
Trousers give more protection from insects than shorts and
guard against serious burns on the legs if forced in daytime
exposure. Cover the head and feet.
KEEP COVERED:
Do not strip off your clothes. Apart from the risk of severe
sunburn, an uncovered body will loose sweat through
evaporation requiring even more to cool it.
But keep the covering as loose as possible so that there is
a layer of insulating air. Sweating will then cool you more
efficiently.
HEADGEAR:
Any hat with a piece of cloth attached to the back will give
some protection to the head and back of the neck but it is
better to copy the headgear of desert peoples.
You need a piece of material about 120cm (4ft) square, a
smaller piece such as a handkerchief and a piece of cord or
cloth (a tie is ideal) to keep them in position.
Make the handkerchief into a wad on top of the head. Fold
the large cloth diagonally, place it over the handkerchief,
the long edge forward. Tie cord or cloth around the head to
secure them.
Allowed to fall freely this will protect from the sun, trap
pockets of air, take advantage of breezes and protect from
sandstorms. At night wrap it around the face for warmth.
DESERT CLOTHING #2:
In order to protect oneself from the sun rays, excessive
perspiration and numerous bugs and harmful insects in the
desert we give you these tips;
1) During the day, cover your body and head, wear long
sleeves and long pants the desert is no beach party.
2) Protect the back of the neck with a piece of cloth.
3) If you have no sunglasses improvise by making a slit
in a piece of cloth just big enough to pass a coin, which
you will wear over the eyes..
4) If you have to abandon some clothing because of the
weight, do not exaggerate, think of the chilly night.
5) Wear clothes that are baggy, nothing tight fitting.
6) Don't expose your skin except in shadowy places, even
reflected the sun rays can burn you.
DESERT & FOOTWEAR:
TO PROTECT WELL YOUR FEET MEANS, IT CAN SAVE YOUR LIFE!
1) KEEP YOUR SHOES FREE OF ALL SAND and insects even if it
means very frequent stops. Better to stop then being grounded.
2) If you don't have boots, make puttee bandages by doing
so; in a piece of cloth, cut 2 bands of 8 to 10cm wide by 1
meter long. Roll these ones in spirals starting at the upper
part of your shoes, this way the sand wont filter in them.
3) Take your shoes off when you rest in the shadow. But be
prudent by so doing, for if your feet swell, it will be
more difficult to put them back in your shoes.
4) Don't walk barefoot, the hot sands can wound your
feet, and the salted surface or a salted crust can burn them.
5) If you find and abandoned vehicle you can make a pair
of sandals using some piece of old tires, but protect
the upper part of your feet against sun rays.
If the soles of your shoes are worn out, better to
reinforce them with a solid piece of cloth or
anything you can improvise with.
6) Rest your feet often, let your sock dry up, turn them
upside down and MAKE SURE no sands nor crease gets in
the socks of Spock.
EYE PROTECTION:
Sunglasses or goggles will help- though many made for use
in temperate climes may offer insufficient protection.
Soot from the fire smeared below the eyes will reduce
glare reflected from the skin. Shield the eyes from glare
and windborne sand with a strip of material. Cut narrow
slits to see through.
FOOTWEAR: DON'T WALK BAREFOOT ON HOT SAND!
Until your feet have become harden. It will burn and
cause blisters. Do not wear sandals which leave the top
of the foot exposed.
Improvise coverings if you have none. Puttees will help
keep the sand out of boots or could be extended to wrap
around the foot over open sandals.
HEALTH:
Most desert illnesses are caused by excessive exposure
to sun and heat. They can be avoided by keeping head and
body covered and remaining in shade until sundown kid.
1) Constipation and pain in passing urine are common and
salt deficiency can lead to cramps.
2) Continued heavy sweating on the body, coupled with
rubbing clothing can produce blockages in the sweat gland
& an uncomfortable skin irritation known as prickly heat.
3) Heat cramps leading to heat exhaustion, heat stroke
and serious sunburn are all dangerous.
DANGERS:
A gradual increase in activity & daily exposure to the
sun will build up a defence. Provided that plenty of
water is available.
4) Various micro-organisms attack the moist areas of the
body-the armpits, the groin & between the toes. Prevention
& treatment are to keep those areas clean & dry.
WARNINGS WARNINGS!
DESERT SORES:
In the desert even the most trivial wound is likely
to become infected if not dealt with STRAIGHT AWAY. Thorns
are easily picked up and should be pulled out as
soon as possible.
Where the skin is broken a large and painful sore
may develop which could prevent walking. Bandage all cuts
with clean dressings and use what medical aids are
available.
STEAD EXPERT NOTES ON DESERT:
STEAD USA Ranger instructions are the same as many
Survival books. So for anyone who wants to survive the
Desert, the heat of the day and lack of water are Number
-1- DANGER.
DRINK WHENEVER YOU ARE THIRSTY. NO MATTER THE QUANTITY
OF WATER YOU MAY HAVE, SMALL OR BIG. RATIONING WILL NOT
HELP.
Many war pilots have thus saved their life by drinking
as much water as they could before any operation over
the desert. It was the water in their body not in their
bottle that kept them alive.
THE GREAT DANGER IS THAT THE AVERAGE MAN DOES NOT
DRINK ENOUGH WATER. His thirst is often slaked before
the water budget is balanced again.
This observation was made by American doctors in the
last few years at various bases in the Arctic and
Antarctic. to put in cold file too
The soldiers stationed there had no thirst because of
the cold climate and therefore drank little, as a result
their bodies suffered from progressive dehydration.
The fact was discovered because men often complain
of CONTINUAL TIREDNESS.
Since then they have been URGED to drink a certain amount
of water every meal, and they soon felt much better.
Clearly this also applies in the desert, and a man need
for water will rise in leaps & bounds and his
expectation of life will drop as rapidly if he is
physically active in great heat.
Yet this is often the mistake the people make while
stranded in the desert.
So drink as soon as you are thirsty no matter your
water reserve, you are not on a movie set to ration water.
DEHYDRATION ADD ON:
In the desert heat, the Thirst itself CAN NOT indicate
you the required quantity of water that your body needs.
In other terms you can drink enough water to quench
your thirst and still suffer from dehydration. If
possible, Drink frequently and in small amount.
If you only drink at meal time, you risk dehydration and
you will tire more easily. To drink only 1 or 2 litre a
day can be disastrous, especially when the temperature is
high.
THE ABSORPTION OF SUCH SMALL QUANTITY CAN NOT
PREVENT DEHYDRATION.
When dehydration tires you out, drink and you will
fast recover your strength. A dehydration up to 10%
of your weight can not be fatal, for ex:
If you weigh 70 kilos and loose 7 kilos by sweating it
will be OK, as long as soon after you drink enough
water to regain the weight lost.
Cold water drunk too fast can give you stomach cramps
so beware. With 29 Centigrade or less you still can
survive even after having lost 25% of your weight.
Yet if it is 32 Centigrade or more, a dehydration making
you loose 15% of your weight can be very unlucky for
your health.
DEHYDRATION SYMPTOMS:
First the thirst followed by general discomfort
then followed by a slowing down of the movements as
well as loosing appetite.
Once you have lost 5% of your weight you can also on top
of the general discomfort above, suffer from nausea.
Loosing from 6 to 10% of your weight you can suffer
from dizziness, headache, breathing difficulties, pricking
in the arms and legs, the dry mouth, livid complexion,
slurred speech & unable to walk.
REMEDY:
Only water can prevent dehydration and maintain your body
in good function. Alcohol, urine, salted water & blood
can only increase the dehydration process. Yet salt water
at sea is a bit different if you check with water chapter.
EXHAUSTION SIGNS:
Paleness, abundant perspiration, skin becoming moist
and cold, deliriums or fainting are the signs.
Lay the person on its back in a shadowy place & give
him water mixed with salt pills 2 of them per water
canteen.
HEAT STROKE:
This can happen suddenly, the face becomes purple, skin
is hot and dry and the victim does not sweat. They suffer
from violent headache and his pulse is fast. Fainting can
result.
You MUST refresh the victim, relax his clothing, lay
him down in a shadowy place but not on the ground,
dampen his cloth but; Don't give any stimulants.
SUN BLINDNESS:
Even if the sand is not as white as the snow, the
danger remains the same to get blind.
So don't look at the sun, protect you eyes, cover your
head to shadow your eyes, use good sunglasses, soot your
cheeks, wrap up your face and head with piece of
cloth as the Bedouins do.
SUN RAYS DANGERS:
It is very dangerous to expose yourself under the
desert sun. You risk collapsing caused by:
CRAMPS:
They are the first signs of heat stroke, you feel them
in the legs muscles & abdominal muscles. In such case you
MUST take rest and absorb water with a bit of salt.
SUN BLINDNESS:
The intense blinding sunlight can lead to a sort of
snow blindness produced by the sandy ground reflecting the
short wave ultraviolet rays.
Slitted disks of cardboard have often served as an effective
substitute for sunglasses. Also smearing the cheeks and lower
eyebrow with black soot from your campfire will help a lot. (Like
football player type of mask.)
SAND DANGERS:
Even the sand itself can be dangerous. Often it "gives"
so much that walking in it becomes an immense labour.
PAY SPECIAL ATTENTION TO THE COLOUR OF THE SAND.
IN SYRIA FOR EX. IT IS THE RED SAND WHICH IS SOFT. IN
LIBYA, THE BLACK.
It is this soft fine sand which the desert wind blows
into the noses, ears, mouth and eyes. One rescued pilot
said that anyone already suffering from dehydration each
single grain will feel as big as a stone.
SANDSTORM & PROTECTION:
In sandstorm which may last several days, this
is particularly troublesome, and the tongue and jaws
will be completely parched with the hot air.
THE BEST PROTECTION AGAINST IT, rescued pilots have
found, is to dig a hole into the ground, cover it with a
tarpaulin firmly fastened down at the sides & crawl underneath.
A sandstorm of course will often completely alter
the outlines of the landscape, leaving valleys where there
were dunes and vice versa.
WARNING! BEARING:
So if before the storm you have given yourself an
objective to make for, you may be lost without a compass,
unless you have marked your direction with an arrow of
stones which will give you your bearing again.
DESERT MOSQUITOES REMEDY:
In many deserts swarms of mosquitoes are driven far into
the waterless interior.
The sand-flies are even worse, tiny but vicious, they
get through the finest mosquito nets and give their
victims painful bites, which cause itching and even fever.
A party of survivors discovered that rubbing themselves
with chewed tobacco drove off the flies.
DESERT WALKING = TOUGH:
In view of all these hazards, it is not surprising
that people stranded in the desert have found that merely
to keep going on foot was the hardest part of their
efforts to survive next to the water problem and this
even when they only walked at night.
SALT LAKES:
After a crash landing during the war, some airmen made
the mistake of walking across crusted over salt lakes.
After the first hour their boots fell off, cut to shreds
by the ground, corroded by the salts crystals. Their
feet became sore & burnt like fire.
In the ends they wrapped their shirts around them &
hobbled on over the sandy ground. Going through this salt
crust was like thin ice in this apparently dried up salt
lake thus giving them great difficulty saving
themselves from this caustic mud.
DRIED UP RIVER BEDS DANGER!:
Walking in dried up river beds has proven equally
dangerous for desert travellers.
These beds are usually stony and during sudden showers
at the edge of the desert, the rain water instead of
sinking in, fast becomes a raging torrent, washing away
everything it meets.
Even if the rainstorm was miles away, the current will
reach you later on, and without warning. (OOPS's!)
BOOTS OFF = GRAVEST ERROR:
Many survivors have made the mistake of taking off
their boots when walking, then they couldn't put them
on again after a rest because their feet were so swollen.
Others have cut holes in the uppers to relieve their
aching feet which allowed sand and stones to get between
soles and leather tops, causing them agonies of pain.
Sweat sores shredded the skin down to the raw flesh,
and complete rest was the only thing which would help.
GONE WITHOUT NOTES & NO COMPASS:
Another way to do wrong is to abandon a wrecked plane
or vehicle without leaving a note of the date and the
direction they are taking or signs en route to show their
direction.
Often they did not even have a compass but simply walked
of at random. If they did not know how to get their
bearings by the stars, this rash procedure usually
proved downright suicidal.
The desert as a rule looks monotonous in colour and
shape with no landmarks to keep the eye on. In the
great sandflats of North Africa survivors have fought on
through the sand for 5 days only to find that they had
been going round in a large circle.
UNDERRATING DISTANCE:
Others again, in the CLEAR desert air have underrated
by many miles the distance to an objective they had
set themselves, such as the top of a hill,
although it constantly looked within an easy reach, it
was really more than a day's walk away.
So they would keep on walking to a point of
complete exhaustion, ALWAYS hoping to be there in a
few minutes, INSTEAD OF TAKING REGULAR REST EVERY HOUR.
NEVER EVER LEAVE UNLESS:
For all those reasons above the survival experts repeat
all the time that in the desert:
You MUST NEVER set off on foot from the scene of a
crash while any hope remains of a search party coming to
look for you.
If there is such a hope, it is ALWAYS better to stay by
the wrecked vehicle or make an emergency landing with your
plane rather than bale out by parachute.
TO BALE OR NOT TO BALE:
This advice is confirmed by both logic and experience.
In the war some pilots landed in the Sahara behind the
enemy lines as often as 7 times during one flight to
repair damage to their planes and leapfrogged back to
their units. Others who have fought in Africa say that
Only the wreck of their plane or vehicle saved them from
certain death.
During the day its shade gave them protection from the
sun and at night, the body-work gave protection against
the raw cold.
As a rule it contained more supplies of food and water than the
crews could have carried along into the desert on foot.
Again a search party can more easily spot the wreck of
a vehicle including an aircraft than it can spot a single
man or even a group, especially if the group is already
some distance from the presumed scene of the crash.
There have been cases where people spotted by search
parties were so revived by supplies from the air that
they left their wreck to walk out of the desert, they
were never seen alive again.
SIGNAL IMPORTANCE:
Above all distress signals can be given better and at
the crucial moment if this is done from a permanent camp
and:
DISTRESS SIGNALS ARE AS IMPORTANT AS WATER SUPPLIES.
If you can not attract the attention of search parties,
you are just as much done as if you have not any drinking
water.
Very few servicemen stranded in the desert during the
war were fortunate enough to be able to call for help by
radio in planes which had to make a crash landing, the
radios had usually been shot to pieces.
Many pilots successfully used the landing searchlights
or flares to send out signals at night. In dark desert
nights these flashes could be seen more than 80 miles away.
So anyone stranded with his car can dismount his
headlights and try to send out distress signals with
them during the night.
After emergency landings pilots have soaked rubber
tires, rubber boots and flying suits in engine oil so
that they could light smouldering fires which would
give off smoke visible from a long distance away.
Those who had bailed out however or left their
aircraft after landing had to be content with less
effective aids.
A German pilot arranged stones in the shape of an
arrow taking care that they would cast the maximum
shadow that would thus be seen from the air. Others
used parachute panels to lay out big SOS signs.
FOOD:
In the desert one can go without food for many days, it
is less important than water, so ration food at the start.
Do not eat in the first 24 hours and in principle do
not eat, unless you have water since food takes a lot of
body water to be digested..
FOOD NOTE 2:
Heat usually produces a loss of appetite- so do not
force yourself to eat. Protein foods increase metabolic
heat & increase water loos and liquids are needed for
digestion.
If water is scarce keep eating to a minimum and then try
to eat only moisture containing foods such as fruits
and vegetables.
Food spoils very quickly and any cans, once opened should
be eaten straight away or kept covered and shaded. Flies
appear from nowhere and settle upon uncovered food.
PLANTS:
Vegetation away from oases and water-holes is likely to
be little more than scrub and grasses-even in the semi-
desertbut grasses are Edible and sometimes plentiful. The
Acacia tree in the scrub provides EDIBLE BEANS.
BEWARE of the Acacia thorns but try all its soft
parts: flowers, fruits, seeds, bark and young shoots.
ACACIA:
Has a double utility, its beans are comestibles and
its roots retain water. These trees look like #Mesquites
and the #Catclaws# of USA South West.
GRASSES = EDIBLE:
The grasses of Sahara and Gobi are neither nutritious
nor palatable but in the Sahara and the Asian deserts
you may find the Desert GOURD a member of the Squash
family.
Its vine can run over the ground for 4-5m (15ft). Chew
its water filled shoots and eat its flowers and orange
sized fruits, the seed of which are edible roasted or
boiled.
The Mescal plant (an Agave from which Tequila is made)
of the Mexican desert, grows with a rosette of thick
tough sharp-tipped leaves.
Its central stalk which rises like a candle to a
flowering head can be eaten. Cut the ends of the leaves
to suck out water.
ANIMALS:
Desert often supports a variety of animal life that
burrows into the sand or hides in any available shade
during the day.
Insects reptiles, small rodents and specially
adapted mammals such as the Fennec Fox of North
Africa the Australian Bandicoot, a hedgehog in the Gobi
and the Jack Rabbit of north America all of which have
big ears to act as cooling aids.
There are geckoes, lizards and snakes. Tortoiseand
amphibians survive from when these were once well watered
lands.
LIZARDS:
They are edible, except for Gila monsters and the
Pearl lizard from South West USA. Mexico and central
America but because of their anchylose walk they
are not really dangerous & only found in the above
desert.
OTHER ANIMALS FOR FOOD:
The Sahara has gerbils and gerboas The Middle East
Caracals & Hyenas. The New World, Kangaroo, rats & coyotes. In
the Kalahari there is a squirrel that uses its tails for shade.
There are even gazelles that manage to get all the
moisture they need from the sap of leaves, though most
large mammals are an indication that there is water
supply within daily reach of their grazing areas.
Birds feathers give them good insulation against heat
and many live and breed long distances from their water
supplysuch as the Road Runner of Arizona (Bee-Peep!)
DESERT EDIBLE PLANTS #2:
In the desert all the tender parts of plants growing
above the ground such as the flowers, fruits seeds &
young shoots and barks can be eaten.
ALL THE GRASS (HERB) ARE EDIBLE EXCEPT THOSE OF THE
SAHARA AND GOBI DESERT.
BEWARE OF ANY PLANTS CONTAINING A MILKY SAP WHICH IS POISON.
DATE:
This tree grows in the African desert, in the South
west Asia, India, & China desert.
MESCAL: (Peyote, STONE?!?)
This plant grows in Europe, Asia, Africa, Mexico
and Antilles. Although growing especially in the desert,
it also grows in damp regions and the Tropics. In full
maturity, the Mescal dresses itself of thick & tough
leaves which ends are solid and sharp.
Its centre, the stem looks like a candle is Edible.
Choose the plants which flowers are not opened yet,
their fibber stems contain a syrupy & delicious
substance. The Mexican used it as medicinal and
hallucinogenic properties.
#LA GOURDE SAVAGE DU DESERT#:
This climbing plant abounds in the Sahara desert, in
Arabia as well as the coast of S.E. India. Its vine
measuring 2.5 to 3 meters long crawls on soil surface
and its fruit gets about the size of an orange.
Its seeds are either roasted or boiled & its flowers
are also Edible. The watery roots of the young shoots
can be chewed to relieve the thirst.
#FIGUIER DE BARBARIE#:
This plant from America now grows in numerous deserts
as well as the sea costs of the world except Arctic
coast. Found in South East of USA, in Mexico, South
America, along Mediterranean coast.
This plant carries pretty yellow or red flowers and
covers itself of grapes with slicing thorns.
Looks strangely like some African cactus which have
milky sap thus poison, but the #Figuier de
Barbarie# NEVER produces this milky sap.
The comestibles fruits look like an egg growing at the
top of the tree.
To eat it you MUST cut the upper part, remove the outer
skin and eat the interior. The #raquettes# are also
comestible Cut the thorns and slice the fleshy cushion in
long strings eaten raw or boiled.
WILD PISTACHIO TREE:
There are 7 species of the wild pistachios. Growing in
arid & semi-arid regions of the Mediterranean Basin, in
Minor Asia & Afghanistan.
Some of them NEVER loose their leaves, others loose them
in dry season. The stems produce 3 grand leaves and
numerous smaller ones. Once ripe, the nuts are hard and
dry, eat them after having them roasted on hot embers.
ALMONDS:
Wild almonds grown in semi-arid regions of Europe,
Western, Mediterranean, Iran, Arabia. China, Madeira,
Acores, Canaries Islands. The Almond tree looks like the
Pear tree, grows up to 12 metres high.
The Almonds grow in grapes and are covered of a
cotonnous skin thick and dry. To extract the almond, open
the fruit and break the centre core. Gather a great
quantity, shell them and keep them in reserve. (High
energy booster as peanuts!)
DESERT PLANTS WARNING!:
We repeat again, beware of any plant giving milky sap, they burn
the skin, will cause blindness if the sap gets in your eyes and
is poisonous if you eat them, it could be lethal.
FIRE:
In the desert one has rarely to make fire except to
purify water, make signals and boil tea. (Preferably
English at 5 o'clock!)
Usually the combustible is extremely rare in the desert, so the
oil and gas if any left from the plane will be precious.
VEHICLES:
For desert travel, fit long-range fuel tanks and
make provision for storing drinking water. Carry further
supplies of both in jerry cans. A jack is no use in soft sand
and an air bag should be carried which is inflated by the
exhaust.
Extra filters will be needed in the fuel line and
air intake. Sand tires MUST be fitted and sand channels
carried to get you moving again when bugged down in loose
sand.
(Sand channels are steel tracks filled with holes about
7 feet long which are put under tires when you get stuck
they act as ramp.)
PROTECTION WHEN LEAVING CAR:
Upon leaving your car in the sun for a while MAKE SURE
you cover the tires with some kind of white cloth or
cardboard to protect tires from overheating, it would be
good to put one over the windshield too if possible.
SPECIAL TUNING:
For higher altitudes the carburettor needs adjustments.
In scrub country, thorn gaiters will reduce the puncture
risks. Antifreeze and suitable wheels and chains are
needed for snow and ice.
As well as sow tire grip when you get stuck. The engine
will need special tuning to match climatic conditions and
its own spares. A spare wheel and a good tool kit are
obvious equipment.
IN HOT CLIMATES:
Even when you have had modifications made to prepare
your vehicle for hot climate conditions you may still
find that you have problems.
In crossing some deserts the considerable temperature
change from day to night can put a strain on any metal and
increase the risk of leaks.
WARNINGS:
NEVER leave a sleeping or injured person or any animal in
a closed car in a hot climate - or even on a sunny day
in temperate regions.
ALWAYS leave windows open to ensure ventilation
(heat exhaustion can be lethal) even if parked in the
shade, as the sun will move.
OVERHEATING:
Stop and allow the engine to cool off. If you are driving
a particularly tricky stretch and stopping is out of
the question switch on the heater.
This will give greater volume to the cooling water
& although the inside of the car will get even hotter,
the engine will cool. When convenient stop and open up the
hood.
DO NOT UNDO THE RADIATOR CAP UNTIL THE TEMPERATURE DROPS.
Check the radiator and all hoses for leaks. If the
radiator is leaking, adding the white of an egg will seal
small holes also chewing gum does the trick.
If there is a large hole squeeze that section of the
copper piping flat to seal it off. It will reduce the
size of the cooling area but if you drive very steadily
you will be able to keep going.
METAL GETS HOT:
Be careful! All metal parts of a car can become hot
enough to cause blister, even fry an egg.
CARE IN SANDY CONDITIONS:
When adding fuel, sand and dust can get into the tank. Rig
a filter over or just inside the inlet to the tank.
DESERT TROUBLES:
CAR STRANDED: "RATTTSS!"
If while driving in the desert, suddenly your car gets
stuck in sand as it would in snow, STOP IMMEDIATELY, pick
up the jack and lift your car, put stones under the
tires and get ready to back up.
If you try giving more gas, you will get deeper in sand
down to the axles and then you can't do nothing or at the
least you are in for a lot of work, much more than having
stopped immediately.
2nd ERROR:
Sure that the second truck or car is soon coming you did
not fill your water containers, this error could be
fatal, if the 2nd truck don't come around for any
accidents can happen to him as well.
3rd ERROR:
In the Mojave desert, 2 men went to cross it without
telling anyone, after getting stuck in the sand they
accelerate thus got stuck for good. This was their 2nd
mistakes.
Then instead of setting of foot as soon as the sun
went down, they waited the next morning to leave this was
their 3rd, now instead of turning back they went ahead
in their first direction this was their last one, they
were found dead a few weeks later.
SO FOR ANYONE WHO WANTS TO SURVIVE THE DESERT, THE HEAT
OF THE DAY AND LACK OF WATER ARE NUMBER -1- DANGER.
