CAMP SANITATION
=1241. Definition.= By "Camp Sanitation" is meant the adoption of
measures to keep the camp in a healthy condition. These measures
comprise:
(a) The disposal, so as to render them harmless and prevent pollution,
of all wastes, refuse and excreta from men and animals in suitable
places provided therefor;
(b) The care exercised in handling, preparing and serving food;
(c) The adequacy of shelter for the men;
(d) The maintenance of proper drainage;
(e) The supply of water for bathing and washing, and the maintenance
of a pure supply for drinking.
=1242. Camp expedients.= "Camp-expedients" is the name given the
mechanical means used to put into effect some of the measures, named
above, connected with camp sanitation, and usually consist of
latrines, kitchen sinks, urinal tubs, rock or earth incinerators, and
drainage ditches.
=1243. Latrines.= The latrines must be dug immediately upon reaching
camp--their construction must not be delayed until the camps have been
pitched and other duties performed. The exact location of the latrines
should be determined by the commanding officer, or by some officer
designated by him, the following considerations being observed:
1. They should be so located as not to contaminate the water supply.
2. They should not be placed where they can be flooded by rain water
from higher ground, nor should they be so placed that they can pollute
the camp by overflow in case of heavy rains.
3. They should be as far from the tents as is compatible with
convenience--if too near, they will be a source of annoyance; if too
far, some men, especially at night, and particularly if affected with
diarrhoea, will defecate before reaching the latrine. Under ordinary
circumstances, a distance of about 50 yards is considered sufficient.
Latrines for the men are always located on the opposite side of the
camp from the kitchens, generally one for each company unit and one
for the officers of a battalion or squadron. They are so placed that
the drainage or overflow can not pollute the water supply or camp
grounds.
When the camp is for one night only, straddle trenches suffice. In
camp of longer duration, and when it is not possible to provide
latrine boxes, as for permanent camps, deeper trenches should be dug.
These may be used as straddle trenches or a seat improvised. When open
trenches are used the excrement must be kept covered at all times with
a layer of earth. In more permanent camps the trenches should be 2
feet wide, 6 feet deep, and 15 feet long, and suitably screened. Seats
with lids are provided and covered to the ground to keep flies from
reaching the deposits; urinal troughs discharging into trenches are
provided. Each day the latrine boxes are thoroughly cleaned, outside
by scrubbing and inside by applying, when necessary, a coat of oil or
whitewash. The pit is burned out daily with approximately 1 gallon oil
and 15 pounds straw. When filled to within 2 feet of the surface, such
latrines are discarded, filled with earth, and their position marked.
All latrines and kitchen pits are filled in before the march is
resumed. In permanent camps and cantonments, urine tubs may be placed
in the company streets at night and emptied after reveille.
All latrines must be filled before marching. The following
illustration shows a very simple and excellent latrine seat which can
be made and kept in the company permanently for use in camps on the
march:
[Illustration: Fig. 1]
Urinal troughs, made of muslin and coated with oil or paint, should
discharge into the trenches.
=1244. Urinal tubs.= When obtainable, urinal tubs or cans should be
placed in the company streets at night, their location being indicated
by lighted lanterns, the tubs or cans being removed at reveille.
=1245. Kitchens.= Camp kettles can be hung on a support consisting of
a green pole lying in the crotches of two upright posts of the same
character. A narrow trench for the fire, about 1 foot deep, dug under
the pole, not only protects the fire from the wind but saves fuel.
[Illustration: Fig. 2]
A still greater economy of fuel can be effected by digging a similar
trench in the direction of the wind and slightly narrower than the
diameter of the kettles. The kettles are then placed on the trench and
the space between the kettles filled in with stones, clay, etc.,
leaving the flue running beneath the kettles. The draft can be
improved by building a chimney of stones, clay, etc., at the leeward
end of the flue.
[Illustration: Fig. 3]
Four such trenches radiating from a common central chimney will give
one flue for use whatever may be the direction of the wind.
[Illustration: Fig. 4]
A slight slope of the flue, from the chimney down, provides for
drainage and improves the draft.
The lack of portable ovens can be met by ovens constructed of stone
and covered with earth to better retain the heat. If no stone is
available, an empty barrel, with one head out, is laid on its side,
covered with wet clay to a depth of 6 or more inches and then with a
layer of dry earth equally thick. A flue is constructed with the clay
above the closed end of the barrel, which is then burned out with a
hot fire. This leaves a baked clay covering for the oven.
A recess can be similarly constructed with boards or even brushwood,
supported on a horizontal pole resting on upright posts, covered and
burnt out as in the case of the barrel.
When clay banks are available, an oven may be excavated therein and
used at once.
To bake in such ovens, first heat them and then close flues and ends.
Food must be protected from flies, dust, and sun. Facilities must be
provided for cleaning and scalding the mess equipment of the men.
Kitchens and the ground around them must be kept scrupulously clean.
Solid refuse should be promptly burned, either in the kitchen fire or
in an improvised crematory.
In temporary camps, if the soil is porous, liquid refuse from the
kitchens may be strained through gunny sacking into seepage pits dug
near the kitchen. Flies must not have access to these pits. Boards or
poles, covered with brush or grass and a layer of earth may be used
for this purpose. The strainers should also be protected from flies.
Pits of this kind, dug in clayey soil, will not operate successfully.
All pits should be filled with earth before marching.
As a precautionary measure against setting the camp on fire, all dry
grass, underbrush, etc., in the immediate vicinity of the kitchen
should be cut down.
In case of a fire in camp, underbrush, spades, shovels, blankets,
etc., are used to beat it out.
Gunny sacks dipped in water are the best fire fighters.
Burning away dried grass and underbrush around exterior of camp is a
great protection against fire from outside.
=1246. Kitchen pits.= Pits of convenient size should be constructed
for the liquid refuse from the kitchens. Solid refuse should be burned
either in the kitchen fire or at some designated place, depending upon
whether the camp is of a temporary or permanent nature. Unless the
camp be of a very temporary nature, the pits should be covered with
boards or other material in order to exclude the flies.
All pits should be filled in with earth before breaking camp.
=1247. Incinerators.= The incineration pit shown in the following
diagram, affords an excellent, simple and economical way of disposing
of camp waste and offal, tin cans and dish-water included:
[Illustration: Fig. 5]
=Description:=
The pit is about 4-1/2 feet long, 1-1/2 feet wide and 2 feet deep at
one end and 2-1/2 at the other. It is partially filled with stones,
the larger ones on the bottom and the smaller on the top. At one end
of the pit the stones extend a little above the surface, and slope
gradually toward the other end until the fire pit is reached ten
inches below the surface of the trench. Over the fire pit, about five
inches above the ground, is placed a crab or a piece of boiler iron,
on which is boiled all the water for washing dishes, etc. The fire pit
is only about one-half of the stone surface, as the radiated heat
keeps the rest of the stones hot, causing all dish and slop water to
evaporate quickly.
Any tin cans that may be thrown into the fire pit are removed after a
short exposure to the heat and placed in a trench especially dug for
the purpose.
The company incinerator shown below was used with great success by
some of our troops at Texas City, Texas. The rocks should not be too
large. The men should be instructed to drop all liquid on the sides
of the incinerator and throw all solid matter on the fire--the liquids
will thus be evaporated and the solids burned. Until the men learn how
to use the incinerator properly, a noncommissioned officer should be
detailed to supervise its use.
[Illustration: Fig. 6]
=1248. Drainage.= When camp is established for an indefinite period,
drainage should be attended to at once. Each tent should have a
shallow trench dug around it and the company and other streets ditched
on both sides, all the trenches and ditches connecting with a ditch
that carries the water from the camp. All surface drainage from higher
ground should be intercepted and turned aside.
=1249. Avoiding old camp sites.= The occupation of old camp sites is
dangerous, since these are often permeated by elements of disease
which persist for considerable periods.
=1250. Changing camp sites.= Camp sites must be changed promptly when
there is evidence of soil pollution or when epidemic disease
threatens. Also, a change of camp site is often desirable in order to
secure a change of surroundings and to abandon areas that have become
dusty and cut up.
=1251. Bunks.= Place a number of small poles about seven feet long
close together, the upper ends resting on a cross pole about six
inches in diameter and the lower ends resting on the ground; or, the
poles may be raised entirely off the ground by being placed on cross
poles supported by forked stakes at the corners; on the poles place
grass, leaves, etc.
=1252. Wood.= The firewood should be collected, cut and piled near the
kitchen. Dry wood is usually found under logs or roots of trees.
If wagons are not heavily loaded it is sometimes a good plan to bring
a few sticks of dry wood from the preceding camp, or to pick up good
wood en route.
=1253. Water.= Precautionary measures should always be taken to
prevent the contamination of the water, and a guard from the first
troops reaching camp should at once be placed over the water supply.
If the water is obtained from a stream, places should be designated as
follows for getting water:
(1) For drinking and cooking;
(2) For watering animals;
(3) For bathing and for washing clothing.
The first designated place should be farthest up the stream; the
others, in the order named, downstream.
Where two bodies of troops are to camp on the same stream one must not
pollute the water to be used by the other. This can be arranged by the
commanders agreeing upon a point where both commands will obtain their
drinking water, upon a second point where animals will be watered,
etc.
If the stream be small, the water supply may be increased by building
a dam.
Small springs may be dug out and each lined with a gabion, or a barrel
or box with both ends removed, or with stones, the space between the
lining and the earth being filled with puddled clay. A rim of clay
should be built to keep out surface drainage. The same method may be
used near swamps, streams, or lakes to increase or clarify the water
supply.
Water that is not known to be pure should be boiled 20 minutes; it
should then be cooled and aerated by being poured repeatedly from one
clean container to another, or it may be purified by apparatus
supplied for the purpose.
Arrangements should be made for men to draw water from the authorized
receptacles by means of a spigot or other similar arrangement. The
dipping of water from the receptacles, or the use of a common drinking
cup, should be prohibited.
In the field it is sometimes necessary to sterilize or filter water.
The easiest and surest way of sterilizing water is by boiling. Boiled
water should be aerated by being poured from one receptacle to another
or by being filtered through charcoal or clean gravel. Unless boiled
water be thus aerated it is very unpalatable and it is with difficulty
that troops can be made to drink it.
Filtration merely clarifies--it does not purify. The following are
simple methods of filtration:
1. Dig a hole near the source of supply so that the water may
percolate through the soil before being used.
2. Sink a barrel or box into the ground, the water entering therein
through a wooden trough packed with clean sand, gravel or charcoal.
3. Place a box or barrel in another box or barrel of larger size,
filling the space between with clean sand, gravel, moss or charcoal,
and piercing holes near the bottom of the outer barrel and near the
top of the inner. The filter thus constructed is partly submerged in
the water to be filtered.
4. Bore a small hole in the bottom of a barrel or other suitable
receptacle, which is partly filled with layers of sand, gravel, and,
if available, charcoal and moss. The water is poured in at the top and
is collected as it emerges from the aperture below.
The amount of water used by troops is usually computed at the rate of
five gallons for each man and ten gallons for each animal per day.
=1254. Rules of sanitation.= The following rules of sanitation are to
be observed:
Men should not lie on damp ground. In temporary camps and in bivouac
they raise their beds if suitable material, such as straw, leaves, or
boughs can be obtained, or use their ponchos or slickers. In cold
weather and when fuel is plentiful the ground may be warmed by fires,
the men making their beds after raking away the ashes.
When troops are to remain in camp for some time all underbrush is
cleared away and the camp made as comfortable as possible. Watering
troughs, shelter in cold weather, and shade in hot, are provided for
the animals, if practicable.
The camp is policed daily after breakfast and all refuse matter
burned.
Tent walls are raised and the bedding and clothing aired daily,
weather permitting.
Tents must be kept clean and in order.
The company street and the ground around the tents must be kept clean.
Food, slop water, rags, paper, empty tin cans, and other trash and
refuse must not be thrown on the ground, but should be put in the box,
can or other receptacle provided for the purpose or thrown into the
incinerator.
The food must be protected from flies, dust and sun.
Under no circumstances must the company street or any other part of
the camp grounds be defiled by urinating or deficating thereon. The
urinal tub and the latrine must invariably be used.
When an open trench is used as a sink, each individual must always
cover his excrement with dirt.
If the sink is inclosed by a box with stool-covers, the covers must
always be put down as soon as one is through using them so as to keep
out the flies. However it is found in practice that men will not do
this therefore it is a good plan to construct the covers so that they
will close automatically when a man rises from the seat.
Kitchen garbage must be burned in a pit or incinerator, or put into
_covered_ cans and hauled away. _The covers must be kept on the cans
at all times_, so as to keep out the flies.
Horses are not to be ridden through camp except on the roadways.
As soon as a tent is pitched it should be ditched.
When it rains the guy ropes must be loosened to prevent the tent pegs
from pulling out and the tent falling down.
The body and the clothes should be cleaned daily as thoroughly as the
means at hand will permit.
In the morning wash the face and neck and don't fail to use your tooth
brush afterward.
In the continued absence of opportunity for bathing it is well to take
an air bath and a moist or dry rub before getting into fresh
underclothes.
If the lack of opportunity to wash clothes continues for any length of
time, soiled clothes and bedding must be frequently exposed to the sun
and air. Sunshine is a good germ killer.
If there are mosquitoes in camp, mosquito bars must be used by men
when asleep, and headnets by men on guard and other duty. Also, if in
a malarial country, about five grains of quinine should be taken
daily, preferably just before supper. In localities where a pernicious
form of malaria prevails, daily doses of ten grains of quinine should
be given.
In the tropics troops are require to camp at least 500 yards away from
all native huts or villages as a preventative measure against malaria.
Men are also prohibited from visiting these places at night for the
same reason.
Clean your mess kit thoroughly after every meal, if practicable,
washing same with soap and boiling water.
The company cooks must keep everything in the kitchen and mess tent
clean with hot water and soap. Boil the utensils and dish rags, and be
sure to throw all slops and garbage into the kitchen incinerator.
Rest and sleep are most important to preserve the health, so, keep the
body rested by plenty of sleep. Do not join idle parties going to walk
the streets of the nearest town at nights, nor sit up late playing
cards.
Observe in camp even with greater care than when in barracks the rules
of health and personal hygiene. (See pars. 1451-1477.)
=1255. Your camp, your home.= A soldier should always look upon his
camp as his home, which it is for the time being. Your tent is your
bedroom; the company street, your sitting-room; the latrine, your
toilet; the mess tent, your dining-room; the camp kitchen, your
kitchen; the bathing facilities, your bathroom. And as you are careful
about keeping your bedroom and the other rooms of your home in a clean
and orderly condition, so should you do your share to keep your tent
and the other parts of camp in a clean, sanitary condition.
