"It is no wonder that the first result of all this is such a delicacy
of skin and lungs that about half the inmates are obliged to give up
going into the open air during the six cold months, because they
invariably catch cold if they do so. It is no wonder that the cold
caught about the first of December has by the first of March become
a fixed consumption, and that the opening of the spring, which ought
to bring life and health, in so many cases brings death.
"We hear of the lean condition in which the poor bears emerge from
their six months' wintering, during which they subsist on the fat which
they have acquired the previous summer. Even so, in our long winters,
multitudes of delicate people subsist on the daily waning strength
which they acquired in the season when windows and doors were open,
and fresh air was a constant luxury. No wonder we hear of spring fever
and spring biliousness, and have thousands of nostrums for clearing
the blood in the spring. All these things are the pantings and
palpitations of a system run down under slow poison, unable to get a
step further.
"Better, far better, the old houses of the olden time, with their great
roaring fires, and their bed-rooms where the snow came in and the
wintry winds whistled. Then, to be sure, you froze your back while you
burned your face, your water froze nightly in your pitcher, your breath
congealed in ice-wreaths on the blankets, and you could write your
name on the pretty snow-wreath that had sifted in through the
window-cracks. But you woke full of life and vigor, you looked out
into the whirling snow-storms without a shiver, and thought nothing
of plunging through drifts as high as your head on your daily way to
school. You jingled in sleighs, you snow-balled, you lived in snow
like a snow-bird, and your blood coursed and tingled, in full tide of
good, merry, real life, through your veins--none of the slow-creeping,
black blood which clogs the brain and lies like a weight on the vital
wheels!"
To illustrate the effects of this poison, the horrors of "the Black
Hole of Calcutta" are often referred to, where one hundred and forty-six
men were crowded into a room only eighteen feet square with but two
small windows, and in a hot climate. After a night of such horrible
torments as chill the blood to read, the morning showed a pile of one
hundred and twenty-three dead men and twenty-three half dead that were
finally recovered only to a life of weakness and suffering.
In another case, a captain of the steamer Londonderry, in 1848, from
sheer ignorance of the consequences, in a storm, shut up his passengers
in a tight room without windows. The agonies, groans, curses, and
shrieks that followed were horrible. The struggling mass finally burst
the door, and the captain found seventy-two of the two hundred already
dead; while others, with blood starting from their eyes and ears, and
their bodies in convulsions, were restored, many only to a life of
sickness and debility.
It is ascertained by experiments that breathing bad air tends so to
reduce all the processes of the body, that less oxygen is demanded and
less carbonic acid sent out. This, of course, lessens the vitality and
weakens the constitution; and it accounts for the fact that a person
of full health, accustomed to pure air, suffers from bad air far more
than those who are accustomed to it. The body of strong and healthy
persons demands more oxygen, and throws off more carbonic acid, and
is distressed when the supply fails. But the one reduced by bad air
feels little inconvenience, because all the functions of life are so
slow that less oxygen is needed, and less carbonic acid thrown out.
And the sensibilities being deadened, the evil is not felt. This
provision of nature prolongs many lives, though it turns vigorous
constitutions into feeble ones. Were it not for this change in the
constitution, thousands in badly ventilated rooms and houses would
come to a speedy death.
One of the results of unventilated rooms is _scrofula_, A distinguished
French physician, M. Baudeloque, states that:
"The repeated respiration of the same atmosphere is _the_ cause of
scrofula. If there be entirely pure air, there may be bad food, bad
clothing, and want of personal cleanliness, but scrofulous disease can
not exist. This disease _never_ attacks persons who pass their lives in
the open air, and always manifests itself when they abide in air which
is unrenewed. _Invariably_ it will be found that a truly scrofulous
disease is caused by vitiated air; and it is not necessary that there
should be a prolonged stay in such an atmosphere. Often, several hours
each day is sufficient. Thus persons may live in the most healthy
country, pass most of the day in the open air, and yet become scrofulous
by sleeping in a close room where the air is not renewed. This is the
case with many shepherds who pass their nights in small huts with no
opening but a door closed tight at night."
The same writer illustrates this, by the history of a French village
where the inhabitants all slept in close, unventilated houses. Nearly
all were seized with scrofula, and many families became wholly extinct,
their last members dying "rotten with scrofula." A fire destroyed a
large part of this village. Houses were then built to secure pure air,
and scrofula disappeared from the part thus rebuilt.
We are informed by medical writers that defective ventilation is one
great cause of diseased joints, as well as of diseases of the eyes,
ears, and skin.
Foul air is the leading cause of tubercular and scrofulous consumption,
so very common in our country. Dr, Guy, in his examination before
public health commissioners in Great Britain, says: "Deficient
ventilation I believe to be more fatal than _all other causes_ put
together." He states that consumption is twice as common among
tradesmen as among the gentry, owing to the bad ventilation of their
stores and dwellings.
Dr. Griscom, in his work on Uses and Abuses of Air, says:
"Food carried from the stomach to the blood can not become _nutritive_
till it is properly oxygenated in the lungs; so that a small quantity of
food, even if less wholesome, may be made nutritive by pure air as it
passes through the lungs. But the best of food can not be changed into
nutritive blood till it is vitalized by pure air in the lungs."
And again:
"To those who have the care and instruction of the rising
generation--the future fathers and mothers of men--this subject of
ventilation commends itself with an interest surpassing every other.
Nothing can more convincingly establish the belief in the existence
of something vitally wrong in the habits and circumstances of civilized
life than the appalling fact that _one fourth_ of all who are born die
before reaching the fifth year, and _one half_ the deaths of mankind
occur under the twentieth year. Let those who have these things in
charge answer to their own consciences how they discharge their duty in
supplying to the young a _pure atmosphere_, which is the _first_
requisite for _healthy bodies_ and _sound minds_."
On the subject of infant mortality the experience of savages should
teach the more civilized. Professor Brewer, who traveled extensively
among the Indians of our western territories, states: "I have rarely
seen a sick boy among the Indians." Catlin, the painter, who resided
and traveled so much among these people, states that infant mortality
is very small among them, the reason, of course, being abundant exercise
and pure air.
Dr. Dio Lewis, whose labors in the cause of health are well known, in
his very useful work, _Weak Lungs and How to Make them Strong_, says:
"As a medical man I have visited thousands of sickrooms, and have not
found in _one in a hundred_ of them a pure atmosphere. I have often
returned from church doubting whether I had not committed a sin in
exposing myself so long to its poisonous air. There are in our great
cities churches costing $50,000, in the construction of which, not
fifty cents were expended in providing means for ventilation. Ten
thousand dollars for ornament, but not ten cents for pure air!
"Unventilated parlors, with gas-burners, (each consuming as much oxygen
as several men,) made as tight as possible, and a party of ladies and
gentlemen spending half the night in them! In 1861, I visited a
legislative hall, the legislature being in session. I remained half
an hour in the most impure air I ever breathed. Our school-houses are,
some of them, so vile in this respect, that I would prefer to have my
son remain in utter ignorance of books rather than to breathe, six
hours every day, such a poisonous atmosphere. Theatres and concert-rooms
are so foul that only reckless people continue to visit them. Twelve
hours in a railway-car exhausts one, not by the journeying, but because
of the devitalized air. While crossing the ocean in a Cunard steamer,
I was amazed that men who knew enough to construct such ships did not
know enough to furnish air to the passengers. The distress of
sea-sickness is greatly intensified by the sickening air of the ship.
Were carbonic acid _only black_, what a contrast there would be
between our hotels in their elaborate ornament!"
"Some time since I visited an establishment where one hundred and fifty
girls, in a single room, were engaged in needle-work. Pale-faced, and
with low vitality and feeble circulation, they were unconscious that
they were breathing air that at once produced in me dizziness and a
sense of suffocation. If I had remained a week with, them, I should,
by reduced vitality, have become unconscious of the vileness of the
air!"
There is a prevailing prejudice against _night air_ as unhealthful
to be admitted into sleeping-rooms, which is owing wholly to sheer
ignorance. In the night every body necessarily breathes night air and
no other. When admitted from without into a sleeping-room it is colder,
and therefore heavier, than the air within, so it sinks to the bottom
of the room and forces out an equal quantity of the impure air, warmed
and vitiated by passing through the lungs of inmates. Thus the question
is, Shall we shut up a chamber and breathe night air vitiated with
carbonic acid or night air that is pure? The only real difficulty about
night air is, that usually it is damper, and therefore colder and more
likely to chill. This is easily prevented by sufficient bed-clothing.
One other very prevalent mistake is found even in books written by
learned men. It is often thought that carbonic acid, being heavier
than common air, sinks to the floor of sleeping-rooms, so that the low
trundle-beds for children should not be used. This is all a mistake;
for, as a fact, in close sleeping-rooms the purest air is below and
the most impure above. It is true that carbonic acid is heavier than
common air, when pure; but this it rarely is except in chemical
experiments. It is the property of all gases, as well as of the two
(oxygen and nitrogen) composing the atmosphere, that when brought
together they always are entirely mixed, each being equally diffused
exactly as it would be if alone. Thus the carbonic acid from the skin
and lungs, being warmed in the body, rises as does the common air,
with which it mixes, toward the top of a room; so that usually there
is more carbonic acid at the top than at the bottom of a room.
[Footnote: Prof. Brewer, of the Tale Scientific School, says: "As a
fact, often demonstrated by analysis, there is generally more carbonic
acid near the ceiling than near the floor."] Both common air and
carbonic acid expand and become lighter in the same proportions; that
is, for every degree of added heat they expand at the rate of 1/480
of their bulk.
Here, let it be remembered, that in ill-ventilated rooms the carbonic
acid is not the only cause of disease. Experiments seem to prove that
other matter thrown out of the body, through the lungs and skin, is
as truly excrement and in a state of decay as that ejected from the
bowels, and as poisonous to the animal system. Carbonic acid has no
odor; but we are warned by the disagreeable effluvia of close
sleeping-rooms of the other poison thus thrown into the air from the
skin and lungs. There is one provision of nature that is little
understood, which saves the lives of thousands living in unventilated
houses; and that is, the passage of pure air inward and impure air
outward through the pores of bricks, wood, stone, and mortar. Were
such dwellings changed to tin, which is not thus porous, in less than
a week thousands and tens of thousands would be in danger of perishing
by suffocation.
These statements give some idea of the evils to be remedied. But the
most difficult point is _how_ to secure the remedy. For often the
attempt to secure pure air by one class of persons brings chills,
colds, and disease on another class, from mere ignorance or
mismanagement.
To illustrate this, it must be borne in mind that those who live in
warm, close, and unventilated rooms are much more liable to take cold
from exposure to draughts and cold air than those of vigorous vitality
accustomed to breathe pure air.
Thus the strong and healthy husband, feeling the want of pure air in
the night, and knowing its importance, keeps windows open and makes
such draughts that the wife, who lives all day in a close room and
thus is low in vitality, can not bear the change, has colds, and
sometimes perishes a victim to wrong modes of ventilation.
So, even in health-establishments, the patients will pass most of their
days and nights in badly-ventilated rooms. But at times the physician,
or some earnest patient, insists on a mode of ventilation that brings
more evil than good to the delicate inmates.
The grand art of ventilating houses is by some method that will empty
rooms of the vitiated air and bring in a supply of pure air _by small
and imperceptible currents_.
But this important duty of a Christian woman is one that demands more
science, care, and attention than almost any other; and yet, to prepare
her for this duty has never been any part of female education. Young
women are taught to draw mathematical diagrams and to solve astronomical
problems; but few, if any, of them are taught to solve the problem of
a house constructed to secure pure and moist air by day and night for
all its inmates.
The heating and management of the air we breathe is one of the most
complicated problems of domestic economy, as will be farther illustrated
in the succeeding chapter; and yet it is one of which, most American
women are profoundly ignorant.
IV.
SCIENTIFIC DOMESTIC VENTILATION.
We have seen in the preceding pages the process through which the air
is rendered unhealthful by close rooms and want of ventilation. Every
person inspires air about twenty times each minute, using half a pint
each time. At this rate, every pair of lungs vitiates one hogshead of
air every hour. The membrane that lines the multitudinous air-cells
of the lungs in which the capillaries are, should it be united in one
sheet, would cover the floor of a room twelve feet square. Every breath
brings a surface of air in contact with this extent of capillaries,
by which the air inspired gives up most of its oxygen and receives
carbonic acid in its stead. These facts furnish a guide for the proper
ventilation of rooms. Just in proportion to the number of persons in
a room or a house, should be the amount of air brought in and carried
out by arrangements for ventilation. But how rarely is this rule
regarded in building houses or in the care of families by housekeepers!
The evils resulting from the substitution of stoves instead of the
open fireplace, have led scientific and benevolent men to contrive
various modes of supplying pure air to both public and private houses.
But as yet little has been accomplished, except for a few of the more
intelligent and wealthy. The great majority of the American people,
owing to sheer ignorance, are, for want of pure air, being poisoned
and starved; the result being weakened constitutions, frequent disease,
and shortened life.
Whenever a family-room is heated by an open fire, it is duly ventilated,
as the impure air is constantly passing off through the chimney, while,
to supply the vacated space, the pure air presses in through the cracks
of doors, windows, and floors. No such supply is gained for rooms
warmed by stoves. And yet, from mistaken motives of economy, as well
as from ignorance of the resulting evils, multitudes of householders
are thus destroying health and shortening life, especially in regard
to women and children who spend most of their time within-doors.
The most successful modes of making "a healthful home" by a full supply
of pure air to every inmate, will now be described and illustrated.
It is the common property of both air and water to expand, become
lighter and rise, just in proportion as they are heated; and therefore
it is the invariable law that cool air sinks, thus replacing the warmer
air below. Thus, whenever cool air enters a warm room, it sinks downward
and takes the place of an equal amount of the warmer air, which is
constantly tending upward and outward. This principle of all fluids
is illustrated by the following experiment:
Take a glass jar about a foot high and three inches in diameter, and
with a wire to aid in placing it aright, sink a small bit of lighted
candle so as to stand in the centre at the bottom. (Fig. 28.) The
candle will heat the air of the jar, which will rise a little on one
side, while the colder air without will begin falling on the other
side. These two currents will so conflict as finally to cease, and
then the candle, having no supply of oxygen from fresh air, will begin
to go out. Insert a bit of stiff paper so as to divide the mouth of
the jar, and instantly the cold and warm air are not in conflict as
before, because a current is formed each side of the paper; the cold
air descending on one aide and the warm air ascending the other side,
as indicated by the arrows. As long as the paper remains, the candle
will burn, and as soon as it is removed, it will begin to go out, and
can be restored by again inserting the paper.
[Illustration: Fig. 28]
[Illustration: Fig. 29]
This illustrates the mode by which coal-mines are ventilated when
filled with carbonic acid. A shaft divided into two passages, (Fig.
29,) is let down into the mine, where the air is warmer than the outside
air. Immediately the colder air outside presses down into the mine,
through the passage which is highest, being admitted by the escape of
an equal quantity of the warmer air, which rises through the lower
passage of the shaft, this being the first available opening for it
to rise through. A current is thus created, which continues as long
as the inside air is warmer than that without the mine, and no longer.
Sometimes a fire is kindled in the mine, in order to continue or
increase the warmth, and consequent upward current of its air.
This illustrates one of the cases where a "wise woman that buildeth
her house" is greatly needed. For, owing to the ignorance of architects,
house-builders, and men in general, they have been building
school-houses, dwelling-houses, churches, and colleges, with the most
absurd and senseless contrivances for ventilation, and all from not
applying this simple principle of science. On this point, Prof. Brewer,
of the Scientific School of Yale College, writes thus:
"I have been in public buildings, (I have one in mind now, filled with
dormitories,) which cost half a million, where they attempted to
ventilate every room by a flue, long and narrow, built into partition
walls, and extending up into the capacious garret of the fifth story.
Every room in the building had one such flue, with an opening into it
at the floor and at the ceiling. It is needless to say that the whole
concern was entirely useless. Had these flues been of proper
proportions, and properly divided, the desired ventilation would have
been secured."
And this piece of ignorant folly was perpetrated in the midst of learned
professors, teaching the laws of fluids and the laws of health.
A learned physician also thus wrote to the author of this chapter:
"The subject of the ventilation of our dwelling-houses is one of the
most important questions of our times. How many thousands are victims
to a slow suicide and murder, the chief instrument of which is want
of ventilation! How few are aware of the fact that every person, every
day, vitiates thirty-three hogsheads of the air, and that each
inspiration takes one fifth of the oxygen, and returns as much carbonic
acid, from every pair of lungs in a room! How few understand that after
air has received ten per cent of this fatal gas, if drawn into the
lungs, it can no longer take carbonic acid from the capillaries! No
wonder there is so much impaired nervous and muscular energy, so much
scrofula, tubercles, catarrhs, dyspepsia, and typhoid diseases. I hope
you can do much to remedy the poisonous air of thousands and thousands
of stove-heated rooms."
In a cold climate and wintry weather, the grand impediment to
ventilating rooms by opening doors or windows is the dangerous currents
thus produced, which are so injurious to the delicate ones that for
their sake it can not be done. Then, also, as a matter of economy, the
poor can not afford to practice a method which carries off the heat
generated by their stinted store of fuel. Even in a warm season and
climate, there are frequent periods when the air without is damp and
chilly, and yet at nearly the same temperature as that in the house.
At such times, the opening of windows often has little effect in
emptying a room of vitiated air. The ventilating-flues, such as are
used in mines, have, in such cases, but little influence; for it is
only when outside air is colder that a current can be produced within
by this method.
The most successful mode of ventilating a house is by creating a current
of warm air in a flue, into which an opening is made at both the top
and the bottom of a room, while a similar opening for outside air is
made at the opposite side of the room. This is the mode employed in
chemical laboratories for removing smells and injurious gases.
The laboratory-closet is closed with glazed doors, and has an opening
to receive pure air through a conductor from without. The stove or
furnace within has a pipe which joins a larger cast-iron chimney-pipe,
which is warmed by the smoke it receives from this and other fires.
This cast-iron pipe is surrounded by a brick flue, through which air
passes from below to be warmed by the pipe, and thus an upward current
of warm air is created. Openings are then made at the top and bottom
of the laboratory-closet into the warm-air flue, and the gases and
smells are pressed by the colder air into this flue, and are carried
off in the current of warm air.
The same method is employed in the dwelling-house shown in a preceding
chapter. A cast-iron pipe is made in sections, which are to be united,
and the whole fastened at top and bottom in the centre of the warm-air
flue by ears extending to the bricks, and fastened when the flue is
in process of building. Projecting openings to receive the pipes of
the furnace, the laundry stove, and two stoves in each story, should
be provided, which must be closed when not in use. A large opening is
to be made into the warm-air fine, and through this the kitchen
stove-pipe is to pass, and be joined to the cast-iron chimney-pipe.
Thus the smoke of the kitchen stove will warm the iron chimney-pipe,
and this will warm the air of the flue, causing a current upward, and
this current will draw the heat and smells of cooking out of the kitchen
into the opening of the warm-air flue. Every room surrounding the
chimney has an opening at the top and bottom into the warm-air Hue for
ventilation, as also have the bathroom and water-closets.
[Illustration: Fig. 30.]
The writer has examined the methods most employed at the present time,
which are all modifications of the two modes here described. One is
that of Robinson, patented by a Boston company, which is a modification
of the mining mode. It consists of the two ventilating tubes, such as
are employed in mines, united in one shaft with a roof to keep out
rain, and a valve to regulate the entrance and exit of air, as
illustrated in Fig. 30. This method works well in certain circumstances,
but fails so often as to prove very unreliable. Another mode is that
of Ruttan, which is effected by heating air. This also has certain
advantages and disadvantages. But the mode adopted for the preceding
cottage plan is free from the difficulties of both the above methods,
while it will surely ventilate every room in the house, both by day
and night, and at all seasons, without any risk to health, and requiring
no attention or care from the family.
By means of a very small amount of fuel in the kitchen stove, to be
described hereafter, the whole house can be ventilated, and all the
cooking done both in warm and cold weather. This stove will also warm
the whole house, in the Northern States, eight or nine months in the
year. Two Franklin stoves, in addition, will warm the whole house
during the three or four remaining coldest months.
