XXXV. EARTH-CLOSETS.

Previous

In some particulars, the Chinese are in advance of our own nation in neatness, economy, and healthful domestic arrangements. In China, nota particle of manure is wasted, and all that with us is sent off in drains and sewers from water-closets and privies, is collected in a neat manner and used for manure. This is one reason that the compact and close packing of inhabitants in their cities is practicable, and it also accounts for the enormous yields of some of their crops.

The earth-closet is an invention which relieves the most disagreeable item in domestic labor, and prevents the disagreeable and unhealthful effluvium which is almost inevitable in all family residences, The general principle of construction is somewhat like that of a water-closet, except that in place of water is used dried earth. The resulting compost is without disagreeable odor, and is the richest species of manure. The expense of its construction and use is no greater than that of the common water-closet; indeed, when the outlays for plumber's work, the almost inevitable troubles and disorders of water-pipes in a house, and the constant stream of petty repairs consequent upon careless construction or use of water-works are considered, the earth-closet is in itself much cheaper, besides being an accumulator of valuable matter.

To give a clear idea of its principles, mode of fabrication, and use, we can not do better than to take advantage of the permission given by Mr. George E. Waring, Jr., of Newport, R. I., author of an admirable pamphlet on the subject, published in 1868 by "The Tribune Association" of New-York. Mr. Waring was formerly Agricultural Engineer of the New-York Central Park, and has given much attention to sanitary and agricultural engineering, having published several valuable works bearing in the same general direction. He is now consulting director of "The Earth-Closet Company," Hartford, Ct., which manufactures the apparatus and all things appertaining to it—any part which might be needed to complete a home-built structure. But with generous and no less judicious freedom, they are endeavoring to extend the knowledge of this wholesome and economical process of domestic sanitary engineering as widely as possible, and so allow us to present the following instructions for those who may desire to construct their own apparatus.

In the brief introduction to his pamphlet, Mr. Waring says:

"It is sufficiently understood, by all who have given the least thought to the subject, that the waste of the most vital elements of the soil's fertility, through our present practice of treating human excrement as a thing that is to be hurried into the sea, or buried in underground vaults, or in some other way put out of sight and out of reach, is full of danger to our future prosperity.

"Our bodies have come out of our fertile fields; our prosperity is based on the production and the exchange of the earth's fruits; and all our industry has its foundation in arts and interests connected with, or dependent on, a successful agriculture.

"Liebig asserts that the greatness of the Roman empire was sapped by the Cloaca Maxima, through which the entire sewage of Rome was washed into the Tiber. The yearly decrease of productive power in the older grain regions of the West, and the increasing demand for manures in the Atlantic States, sufficiently prove that our own country is no exception to the rule that has established its sway over Europe.

"The large class who will fail to feel the force of the agricultural reasons in favor of the reform which this pamphlet is written to uphold, will realize, more clearly than farmers will, the importance of protecting dwellings against the gravest annoyance, the most fertile source of disease, and the most certain vehicle of contagion."

Nevertheless, Mr. Waring thinks that the agricultural argument is no mean or unimportant one, and says:

"The importance of any plan by which the excrement of our bodies may be returned to our fields is in a measure shown in the following extract from an article that I furnished for the American Agricultural Annual for 1868.

"The average population of New York City—including its temporary visitors—is probably not less than 1,000,000. This population consumes food equivalent to at least 30,000,000 bushels of corn in a year. Excepting the small proportion that is stored up in the bodies of the growing young, which is fully offset by that contained in the bodies of the dead, the constituents of the food are returned to the air by the lungs and skin, or are voided as excrement. That which goes to the air was originally taken from the air by vegetation, and will be so taken again: here is no waste. The excrement contains all that was furnished by the mineral elements of the soil oil which the food was produced. This all passes into the sewers, and is washed into the sea. Its loss to the present generation is complete."

… "30,000,000 bushels of corn contain, among other minerals, nearly 7000 tons of phosphoric acid, and this amount is annually lost in the wasted night-soil of New-York City. [Footnote: Other mineral constituents of food—important ones, too—are washed away in even greater quantities through the same channels; but this element is the best for illustration, because its effect in manure is the most striking, even so small a dressing as twenty pounds per acre, producing a marked effect on all cereal crops. Ammonia, too, which is so important that it is usual in England to estimate the value of manure in exact proportion to its supply of this element, is largely yielded by human excrement.]

"Practically the human excrement of the whole country is nearly all so disposed of as to be lost to the soil. The present population of the United States is not far from 35,000,000. On the basis of the above calculation, their annual food contains 200,000 tons of phosphoric acid, being the amount contained in about 900,000 tons of bones, which, at the price of the best flour of bone, (for manure,) would be worth over $50,000,000. It would be a moderate estimate to say that the other constituents of food are of at least equal value with the other constituents of the bone, and to assume $50,000,000 as the money value of the wasted night-soil of the United States every year.

"In another view, the importance of this waste can not be estimated in money. Money values apply, rather, to the products of labor and to the exchange of these products. The waste of fertilizing matter reaches farther than the destruction or exchange of products: it lessens the ability to produce.

"If mill-streams were failing year by year, and steam were yearly losing force, and the ability of men to labor were yearly growing less, the doom of our prosperity would not be more plainly written, than if this slow but certain impoverishment of our soil were sure to continue.

…. "But the good time is coming, when (as now in China and Japan) men must accept the fact that the soil is not a warehouse to be plundered—only a factory to be worked. Then they will save their raw material, instead of wasting it, and, aided by nature's wonderful laws, will weave over and over again the fabric by which we live and prosper. Men will build up as fast as men destroy; old matters will be reproduced in new forms, and, as the decaying forests feed the growing wood, so will all consumed food yield food again."

With the above brief extract, we shall cease using marks of quotation, as the following information and statements are appropriated bodily, either directly or with mere modifications for brevity, from the little pamphlet of Mr. Waring.

The earth-closet is the invention of the Rev. Henry Moule, of Fordington
Vicarage, Dorsetshire, England.

It is based on the power of clay, and the decomposed organic matter found in the soil, to absorb and retain all offensive odors and all fertilizing matters; and it consists, essentially, of a mechanical contrivance (attached to the ordinary seat) for measuring out and discharging into the vault or pan below a sufficient quantity of sifted dry earth to entirely cover the solid ordure and to absorb the urine.

The discharge of earth is effected by an ordinary pull-up similar to that used in the water-closet, or (in the self-acting apparatus) by the rising of the seat when the weight of the person is removed.

The vault or pan under the seat is so arranged that the accumulation may be removed at pleasure.

From the moment when the earth is discharged, and the evacuation is covered, all offensive exhalation entirely ceases. Under certain circumstances, there may be, at times, a slight odor as of guano mixed with earth; but this is so trifling and so local, that a commode arranged on this plan may, without the least annoyance, be kept in use in any room.

This statement is made as the result of personal experience. Mr. Waring says:

"I have in constant use in a room in my house an earth-closet commode; and even when the pan is entirely full, with the accumulation of a week's use, visitors examining it invariably say, with some surprise, 'You don't mean that this particular one has been used!'"

HOW TO MAKE AN EARTH-CLOSET.

The principle on which the earth-closet is based is as free to all as is the earth itself, and any person may adopt his own method of applying it. All that is necessary is to have a supply of coarsely sifted sun-dried earth with which to cover the bottom of the vessel to be used, and after use to cover the deposit. A small box of earth, and a tin scoop are sufficient to prevent the gravest annoyance of the sickroom. But, of course, for constant use, it is desirable to have a more convenient apparatus—something which requires less care, and is less troublesome in many ways.

To this end, the patent invention of Mr. Moule is applicable. This comprises a tight receptacle under the seat, a reservoir for storing dry earth, and an apparatus to measure out the requisite quantity, and throw it upon the deposit.

[Illustration: Fig. 67.]

The arrangement at the mechanism is shown in Fig. 67. A hopper-shaded reservoir, made of galvanized iron, is supported by a framework at the back of the seat, which rests on the framework a, a. Connected with the handle at the right-hand side, there is an iron lever, which operates a movable box at the bottom of the reservoir, and causes it to discharge its contents directly under the seat. When the handle is dropped, the box returns to its position, and is immediately filled preparatory to another use.

The hopper-shaped reservoir is supported by two pivots, and has a slight rocking or vibrating motion imparted to it by each lifting of the lever. This prevents the earth from becoming clogged, and insures its regular delivery.

[Illustration: Fig. 68 THE "PULL-UP" APPARATUS.]

The construction is more clearly shown in Fig. 68.

In this figure, A is the vibrating hopper for holding the earth. Its capacity may be increased to any desired extent by building above it a straight-sized box of any height. It is not unusual, in fixed privies, to make this reservoir large enough to hold a supply for several months. As the earth is dry, there is no occasion for the use of any thing better than common pine boards in making this addition to the reservoir.

B is one side of the wooden, frame by which the hopper is supported and it may be made of one inch pine or spruce.

C is a box of lacquered or galvanized iron, without either top or bottom. It moves on two pivots, one of winch is shown on its exposed side. In its present position, its upper end opens into the hopper, and its lower end is dosed by the stationary board over which it stands. When the handle is pulled up, the lever, which is connected with the box, jerks it rapidly up, so that its back side closes the opening of the reservoir, and its bottom opens to the front. In its movement it discharges its contents of earth forward under the seat. When the handle is dropped, the box returns to its natural position, and is charged again.

D is one of the pivots—a corresponding one being on the other side—by which the hopper is supported, and on which it vibrates.

a, a, a, a, a, a, are the parts of the framework, the dimensions of which in feet and inches are given.

The only essential part not shown is an earthen-ware pan without a bottom, similar to the pan of a water-closet, only not so deep and with a larger opening, which is attached to the under side of the seat, and which in a measure prevents the rising of dust, and conducts the urine to the point at which the most earth falls. This is the least important part of the invention, but it has a certain advantage.

The self-acting apparatus is more complicated, and persons wishing it would do best to apply directly to the Company.

THE ORDINARY PRIVY.

In the circular published by the Earth-Closet Company, the following directions are given:

[Illustration: Fig. 69.—Commode, 3 ft. 3 in. high, 1 ft. 11 in. wide, 2 ft. 2 in. deep.]

"An ordinary fixed closet requires the apparatus to be placed at the back of, and in connection with, the usual seat; the reservoir for containing the earth being placed above it. Under it there should be a chamber or vault about four feet by three wide, and of any convenient depth, with a paved or asphalted bottom, and the sides lined with cement. Should there be an existing cesspool, it may be altered to the above dimensions. Into this the deposit and earth fall, and may remain there three, six, or twelve months, and continue perfectly inodorous and innoxious, merely requiring to be occasionally leveled by a rake or hoe. If, however, it should be found impossible or inconvenient to have a vault underneath, a movable trough, of iron or tarred wood, on wheels, may be substituted. In this case, it will be advisable to raise the seat somewhat above the floor, to allow the trough to be of sufficient size.

"By one form of construction, (the 'pull-up,') the pulling up of a handle releases a sufficient quantity of the dry earth, which is thrown into the pit or vault, covering the deposit and completely preventing all smell. By another, (the 'self-acting,') the same effect is produced by the action of the seat. The apparatus may be placed in, and adapted to, almost any existing closet or privy, and so arranged that the supply and removal of earth may be carried on inside or outside as desired."

The following is taken from the company's circular:

"In the commode, the apparatus and earth-reservoir are self-contained, and a movable pail takes the place of the chamber or vault above described. This must be emptied as often as necessary, and the contents may be applied to the garden or field, or be allowed to accumulate in a heap under cover until wanted for use. This accumulation is inodorous, and rapidly becomes dry. The commode can stand in any convenient place in or out of doors. For use in bedrooms, hospital wards, infirmaries, etc., the commode is invaluable. It is entirely free from those faint, depressing odors common to portable water-closets and night-stools, and through its admission one of the greatest miseries of human life, the foul smells of the sick-room, and one of the most frequent means of communicating infection, may be entirely prevented. It is invariably found that, if any failure takes place, it arises from the earth not being properly dry. Too much importance can not be attached to this requirement. The earth-commode will no more act properly without dry earth, than will a water-closet without water.

"These commodes are made in a variety of patterns, from the cottage commode to the more expensive ones in mahogany or oak, and vary in price accordingly. They are made to act either by a handle, as in the ordinary water-closet, or self-acting on rising from the seat. The earth-reservoir is calculated to hold enough for about twenty-five times; and where earth is scarce, or the manure required of extraordinary strength, the product may be dried as many as seven times, and without losing any of its deodorizing properties.

"If care be taken to cast one service of earth into the pail when first placed in the commode, and to have the commonest regard to cleanliness, not the least offensive smell will be perceptible, though the receptacle remain unemptied for weeks. Care must also be taken, that no liquid, but that which they are intended to receive, be thrown into the pails."

The pail used in the commode is made of galvanized iron, and is shaped very much like an ordinary coal-hod. It has a cover of the same material, and it may be carried from an upper floor with no more offensiveness than a hodful of common earth.

Fig. 70 represents a cross-section of the commode, and will enable the reader more clearly to understand the construction and operation of the apparatus.

a is the opening in the seat; b, the "pan;" c, the pail for receiving the deposit; d, the hopper for containing the earth supply; e, the box by which the earth is measured, and by which it is thrown into the pail when moved to the position e' by the operation of the "pull-up;" f, a door by which the pail is shut in; g, the cover of the seat; h, the cover of the hopper; i a platform which prevents the escape of earth from e.

[Illustration: Fig. 70 HOW TO USE THE EARTH-CLOSET.]

Under this head, the circular issued by the original London company contains the following:

"The first requirement for the proper working of the earth-closet is earth perfectly dry and sifted. Earth alone is proved to be the best deodorizer, and far superior to any disinfectants; but where it is difficult to obtain earth abundantly, sifted ashes, as before stated, may be mixed with, it in proportion of two of earth to one of ashes.

"As the first requirement is dry earth sifted, and as this is usually thought to be a great difficulty in the way of the adoption of the dry earth system, the following remarks will at once remove such an impression.

"The earth-commode and closet, if used by six persons daily, will require, on an average, about one hundred weight of earth per week. This may be dried for family use in a drawer made to fit under the kitchen range, and which may be filled with earth one morning and left until the next. The drawer should reach to within two inches of the bottom bar of the grate. A frame with a handle, covered with fine wire-netting, forming a kind of shovel, should be placed on this drawer; the finer ashes will fall through, mixing with the earth, whilst the cinders will remain on the top, to be, from time to time, thrown on the fire.

"Of course, the most economical method is to provide in the summer-time a winter store of dry earth, which may be kept in an out-house, shed, or other convenient place, just as we lay in a winter store of coals.

"THINGS TO BE OBSERVED

"Let one fall of earth be in the pail before using.
"The earth must be dry and sifted.
"Sand must not be used.
"No 'slops' must be thrown down.
"The handle must be pulled up with a jerk, and let fall sharply."

REPEATED USE OF EARTH

Concerning the value and use of the product of the earth-closet, the following is copied from the London company's circular. (It will be noticed that reference is made, to the repeated use of the same earth. When the ordure is completely dried and decomposed, it has not only lost its odor, but it has become, like all decomposed organic matter, an excellent disinfectant, and the fifth or sixth time that the same earth is passed through the closet it is fully as effective in destroying odors as it was when used for the first time, and of course each use adds to its value as manure, until it becomes as strong as Peruvian guano, which is now worth seventy-five dollars per ton. In fact, it may be made so rich that one hundred pounds will be a good dressing for an acre of land.)

"If the closet is over a water-tight cesspool or pit, it will require emptying at the end of three or six months. The produce, which will be quite inodorous, should be thrown, together in a heap, sheltered from wet, and occasionally turned over. At the end of a few weeks, it will be dry and fit for use.

"If the receptacle be an iron trough or pail, the contents should be thrown together, re-dried, and used over again, four or five times. In a few weeks they will be dry and fit for use; the value being increased by repeated action. The condition of the manure should be much the same as that of guano, and fit for drilling."

The inventor of the earth-closet, Rev. Mr. Moule, says:

"It was to this point (the power of earth or clay to absorb the products of the decomposition of manure) but particularly to the repeated action, and consequently the repeated use of the same earth, that I first directed the attention of the public. I then pointed out: First. That a very small portion of dry and sifted earth (one and a half pints) is sufficient by covering the deposit, to prevent fermentation, (which so soon sets in whenever water is used,) and the consequent generation and emission of noxious gases. Second. That if within a few hours, or even a few days, the mass that would be formed by the repeated layers of deposit, be intimately mixed by a coarse rake or spade, or by a mixer made for the purpose, then, in five or ten minutes, neither to the eye or sense of smell is any thing perceptible but so much earth…. When about three cart-loads of sifted earth had thus been used for my family, (which averaged fifteen persons,) and left under a shed, I found that the material first employed was sufficiently dried to be used again. This process of alternate mixing and drying was renewed five times, the earth still retaining its absorbent powers apparently unimpaired. Of the visitors taken to the spot, none could guess the nature of the compost, though in some cases the heap which they visited in the afternoon had been turned over that same morning …

"It is only in towns, where the delivery, stowage, and removal of earth is attended with cost and difficulty, that any artificial aid for drying the compost would be desirable. On premises not cramped for space, the atmosphere, especially with a glass roof to the shed, will act sufficiently fast.

"You may by means of it (the earth system) have a privy close to the house and a closet up-stairs, from neither of which shall proceed any offensive smell or any noxious gas. A projection from the back of the cottage, eight feet long and six feet wide, would be amply sufficient for this purpose. The nearer three or four feet down-stairs, would be occupied by the privy, in which, by the seat, would be a receptacle for dry earth. The 'soil' and earth would fall into the further five or four feet, which would form the covered and closed shed for mixing and drying. Up-stairs, the arrangement would be much the same, the deposit being made to fall clear of every wall. Through, this closet the removal of noxious and offensive matters in time of sickness, and of slop-buckets, would be immediate and easy; and if the shed below be kept well supplied with earth, all effluvium would be almost immediately checked. As to the trouble which this will cause, a very little experience will convince the cottager that it is less instead of greater, than the women generally go through at present, while the value of the manure will afford an inducement to exertion.

. . . . . . . . .

"The truth is, that the machinery is more simple, much less expensive, and far less liable to injury than that of the water-closet. The supply of earth to the house is as easy as that of coals. To the closet it may be supplied more easily than water is supplied by a forcing-pump, and to the commode it can be conveyed just as coal is carried to the chamber. After use, it can be removed in either case by the bucket or box placed under the seat, or from the fixed reservoir, with less offense than that of the ordinary slop-bucket—indeed, (I speak after four years' experience,) with as little offense as is found in the removal of coal-ashes. So that, while servants and others will shrink from novelty and at first imagine difficulties, yet many, to my knowledge, would now vastly prefer the daily removal of the bucket or the soil to either the daily working of a forcing-pump or to being called upon once a year, or once in three years, to assist in emptying a vault or cesspool."

To the above complete and convincingly apt arguments and statements of fact, we do not care to add any thing. All that we desire is to direct public attention to the admirable qualities of this Earth System, and to suggest that, at least for those living in the country away from the many conveniences of city life, great water power, and mechanical assistance, the use of it will conduce largely to the economy of families, the health of neighborhoods, and the increasing fertility and prosperity of the country round about.
