Household words, no. 9, May 25, 1850
Part 3
The eastern turret is devoted to the Time Ball and its mechanism. Far out at sea—away from all sources of information but those to be asked of the planets, his compass, his quadrant, his chronometer, and his almanack, the mariner feels the value of _time_ in a way which the landsman can scarcely conceive. If his chronometer is right, he may feel safe; let him have reason to doubt its accuracy, and he knows how the perils surrounding him are increased. An error of a few seconds in his time may place him in danger—an error of a few minutes may lead him to steer blindly to his certain wreck. Hence his desire when he is leaving port to have his time-pieces right to a second; and hence the expenditure of thought, and labour, and money, at the Greenwich Observatory, to afford the shipping of the great port of London, and the English navy, the exact time—true to the tenth of a second, or six hundredth of a minute—and to afford them also a book, the Nautical Almanack, containing a mass of astronomical facts, on which they may base their calculations, with full reliance as to their accuracy. Every day for the last seventeen years, at five minutes before one o’clock, the black ball five feet across and stuffed with cork, is raised halfway up its shaft above the eastern turret of the Observatory;—at two-and-a-half minutes before that hour, it rises to the top. Telescopes from many a point, both up and down the river, are now pointed to this dark spot above the Greenwich trees, and many an anxious mariner has his time-pieces beside him, that their indications may be made true. Watch the Ball as you stand in the Park. It is now just raised. You must wait two minutes and a half, and as you do so, you feel what a minute may be. It seems a long, palpable, appreciable time, indeed. In the turret below, stands a clock telling the true time, gained by a laborious watching of the _clock-stars_; and beside the clock, is a man with a practised hand upon a trigger, and a practised eye upon the face of the dial. One minute—two minutes pass. Thirty seconds more, and the trigger has released the Ball. As it leaves the top of the shaft, it is one o’clock to the tenth of a second. By the time it has reached the bottom it is some five seconds later.
Leaving the Ball Turret, and the old building which it surmounts, the new Observatory, where the chief work of the establishment is done, claims our notice. This attention would scarcely be given to its outward appearance for it is a long low building, scarcely seen beyond its own boundaries. The Greenwich Observatory is not a _show_ place, but an eminently practical establishment. St. Petersburg and other cities have much more gorgeous buildings devoted to astronomical purposes, and Russia and other countries spend much more money on astronomy than England does, yet the Greenwich Tables have a world-wide reputation, and some of them are used as the groundwork for calculations in all Observatories at home and abroad. The astronomer does not want marble halls or grand saloons for his work. Galileo used a bell-tower at Venice, and Kepler stood on the bridge at Prague to watch the stars. The men, not the buildings, do the work. No disappointment need be felt, then, to find the modern Observatory a range of unadorned buildings running east and west, with slits in the roof, and in some of the walls. Within these simple buildings are the instruments now used, displaying almost the perfection of mechanical skill in their construction and finish—beautifully adapted to the object they have to fulfil, and in perfect order. They are fixed on solid piers of masonry, deeply imbedded in the earth, to secure freedom from vibration—a quality better obtained when the foundations are on sand or gravel than when on rock.
To describe the instruments by their technical names, and to go into any particulars of the instruments they have superseded, would take space, only to do the work of a scientific treatise. Enough, therefore, to say that there are the telescopes best adapted to the chief duty of the place, which is, watching the moon whenever she is visible; watching the _clock-stars_, by which the true time is calculated more exactly than it could be from observations of the sun alone; and watching other planetary bodies as they pass the meridian. Eclipses, occultations, and other phenomena, of course, have their share of attention, and add to the burden of the observer’s duties.
The staff of the Observatory includes a chief astronomer, Mr. Airy, with a salary of 800_l._ a year; and six assistants who are paid, 470_l._, 290_l._, 240_l._, 150_l._, 130_l._, and 130_l._, respectively. This does not include the officers of the Meteorological branch of the establishment, to be spoken of hereafter; and which consists of Mr. Glaisher, with 240_l._ a year, one assistant at 120_l._, and two additional computers. At times, when these scientific labourers have collected more observations than they are able to work out; additional help is summoned, in shape of the body of scientific clerks before spoken of; who, seated at desks, cast up the accounts the planetary bodies, including such regular old friends as the moon and fixed stars, but not forgetting those wandering celestial existences that rush, from time to time, over the meridian, and may be fairly called the chance customers of the astronomer.
Though the interior of the Observatory seems so still, the life of those employed there has its excitements. Looking through telescopes forms a small part only of their duty—and that duty cannot be done when the weather is unfavourable. On cloudy days the observer is idle; in bright weather he is busy; and a long continuance of clear days and nights gives him more employment than he can well complete. Summer, therefore, is his time of labour; winter his time of rest. It appears that in our climate the nights, on the whole, are clearer than the days, and evenings less cloudy than mornings. Every assistant takes his turn as an observer, and a chain of duty is kept up night and day; at other periods, the busiest portion of the twenty-four hours at the Observatory, is between nine in the morning and two in the afternoon. During this time they work in silence, the task being to complete the records of the observations made, by filling in the requisite columns of figures upon printed forms, and then adding and subtracting them as the case requires. Whilst thus engaged, the assistant who has charge of an instrument looks, from time to time, at his star-regulated clock, and when it warns him that his expected planet is nearly due, he leaves his companions, and quietly repairs to the room where the telescope is ready. The adjustment of this has previously been arranged with the greatest nicety. The shutter is moved from the slit in the roof, the astronomer sits upon an easy chair with a moveable back. If the object he seeks is high in the heavens, this chair-back is lowered till its occupant almost lies down; if the star is lower, the chair-back is raised in proportion. He has his note-book and metallic pencil in hand. Across the eye-piece of the telescope are stretched seven lines of spider-web, dividing the field of view. If his seat requires change, the least motion arranges it to his satisfaction, for it rests upon a railway of its own. Beside him is one of the star-clocks, and as the moment approaches for the appearance of the planet, the excitement of the moment increases. ‘The tremble of impatience for the entrance of the star on the field of view,’ says an Edinburgh Reviewer, ‘is like that of a sportsman whose dog has just made a full point, and who awaits the rising of the game. When a star appears, the observer, in technical language, _takes a second from the clock face_; that is, he reads the second with his eye, and counts on by the ear the succeeding beats of the clock, naming the seconds mentally. As the star passes each wire of the transit, he marks down in his jotting-book with a metallic pencil the second, _and the second only_, of his observation, with such a fraction of a second as corresponds, in his judgment, to the interval of time between the passage of the star, and the beat of the clock which preceded such passage.’
An experienced observer will never commit an error in this mental calculation, exceeding the tenth of a second, or six hundredth of a minute. When the star has been thus watched over the seven cobweb lines (or wires), the observer jots down the hour and minute, in addition to the second, and the task is done. Stars, not very near the sun, may be seen in broad daylight, but, at night, it is requisite to direct a ray of light from a lamp, so far to enlighten the field of the telescope, as to permit the spider lines to be seen running across the brighter ground on which the expected star is to be visible.
The adjustment of the instruments is a task of great nicety. If they are out of trim only a shadow of a shade of a hair’s-breadth, the desired accuracy is interfered with, and they have to be re-adjusted. Temperature is of course an important element in their condition, and a slight sensibility may do mischief. The warmth of the observer’s body, when approaching the instruments, has been known to affect their accuracy; and to avoid such sources of error, instruments have at times been cased in flannel, that the non-conducting powers of that homely fabric might screen the too-sensitive metal.
Sunday is a comparative holiday at the Observatory, for then, except when any extraordinary phenomena are expected, the only duty done is to drop the Time Ball, and observe the moon’s place. The moon is never neglected, and her motions have been here watched, during the last hundred and seventy years, with the most pertinacious care,—to the great service of astronomy, and the great benefit of navigation.
The library should not pass unnoticed. It is small; but being devoted to works upon astronomy, and the kindred sciences, there is ample room for all that has hitherto been written on the subject, or that can, for many generations, be produced. The observations of a lifetime spent in watching the stars may be printed in marvellously few pages. A glance through the Greenwich Astronomical Library gives a rough general idea of what the world has done and is doing for the promotion of this science. Russia contributes large, imperial-looking tomes, that tell of extended observations made under the munificent patronage of a despot; Germany sends from different points a variety of smaller, cheaper-looking, yet valuable contributions; France gives proofs of her genius and her discoveries; but _her_ forte is not in observation. The French are bad observers. They have no such proofs of unremitting, patient toil in search of facts, as those afforded in the records of the Greenwich Tables of the Moon. Indeed, Greenwich, as we have already said, is a working Observatory; and those who go into its library, and its fire-proof manuscript-room, and see how its volumes of observations have been growing from the small beginnings of the days of Flamstead and Halley, to those of our later and more liberal times, will have good reason to acknowledge that the money devoted to this establishment has been well employed.
One other spot must be noticed as amongst the notable things in this astronomical sanctum. It is the Chronometer-room, to which, during the first three Mondays in the year, the chief watchmakers of London send in their choicest instruments for examination and trial. The watches remain for a good portion of a year; their rates being noted, day by day, by two persons; and then the makers of the best receive prizes, and their instruments are purchased for the navy. Other competitors obtain certificates of excellence, which bring customers from the merchant service; whilst others pass unrewarded. To enter the room where these admirable instruments are kept, suggests the idea of going into a Brobdingnag Watch-factory. Round the place are ranged shelves, on which the large watches are placed, all ticking in the most distinct and formidable way one against another. When they first arrive, in January, they are left to the ordinary atmospheric temperature for some months. Their rates being taken under these circumstances, a large stove in the centre of the apartment is lighted, and heat got up to a sort of artificial East India or Gold Coast point. Tried under these influences, they are placed in an iron tray over the stove, like so many watch-pies in a baker’s dish, and the fire being encouraged, they are literally kept baking, to see how their metal will stand that style of treatment. Whilst thus hot, their rates are once more taken; and then, after this fiery ordeal, such of them as their owners like to trust to an opposite test, are put into freezing mixtures! Yet, so beautifully made are these triumphs of human ingenuity—so well is their mechanism ‘corrected’ for compensating the expansion caused by the heat, and the contraction induced by the cold—that an even rate of going is established, so nearly, that its variation under opposite circumstances becomes a matter of close and certain estimate.
The rates of chronometers on trial for purchase by the Board of Admiralty, at the Observatory, are posted up and printed in an official form. Upon looking to the document for last year, we find a statement of their performances during six months of 1849, with memoranda of the exact weeks during which the chronometers were exposed to the open air at a north window; the weeks the Chronometer-room was heated by a stove, the chronometers being dispersed on the surrounding shelves; and the weeks during which they were placed in the tray above the stove. The rate given during the first week of trial is in every case omitted; like newly entered schoolboys their early vagaries are not taken into account; but after that, every merit and every fault is watched with jealous care, and, when the day of judgment comes, the order of the arrangement of the chronometers in the list is determined solely by consideration of their irregularities of rate as expressed in the columns, ‘Difference between greatest and least,’ and, ‘Greatest difference between one week and the next.’
The Royal Observatory, according to a superstition not wholly extinct, is the headquarters, not only of Astronomy, but of Astrology. The structure is awfully regarded, by a small section of the community which ignorance has still left amongst us, as a manufactory of horoscopes, and a repository for magic mirrors and divining-rods. Not long ago a well-dressed woman called at the Observatory gate to request a hint as to the means of recovering a lost sum of money; and recently, somebody at Brighton dispatched the liberal sum of five shillings in a post-office order to the same place, with a request to have his nativity cast in return! Another, only last year, wrote as follows:—‘I have been informed that there are persons at the Observatory who will, by my enclosing a remittance and the hour of my birth, give me to understand _who is to be my wife_? An early answer, stating all particulars, will oblige,’ &c.
This sketch descriptive of its real duties and uses are not necessary to relieve the Greenwich Observatory from the charge of being an abode of sorcerers and astrologers. A few only of the most ignorant can yet entertain such notions of its character; but they are not wholly unfounded. Magicians, whose symbols are the Arabic numerals, and whose _arcana_ are mathematical computations, daily foretell events in that building with unerring certainty. They pre-discover the future of the stars down to their minutest evolution and eccentricity. From data furnished from the Royal Observatory, is compiled an extraordinary prophetic Almanack from which all other almanacs are copied. It foretells to a second when and where each of the planets may be seen in the heavens at any minute for the next three years. The current number of the Nautical Almanack is for the Year of Grace 1853.
In this quiet sanctuary, then, the winds are made to register their own course and force, and the rain to gauge its own quantity as it falls; the planets are watched to help the mariner to steer more safely over the seas; and the heavens themselves are investigated for materials from which their future as well as their past history may be written.
SWEDISH FOLK-SONGS.
THE DOVE ON THE LILY. There sits a pure dove on a lily so white, On midsummer morning:— She sang of Christ Jesus from morning to night, In Heaven there is great joy, O!
She sang, and she sang, ’twas a joy to hear, Expecting a maiden in Heaven that year.
“And should I reach Heaven ere twelvemonths are o’er, Sickness and pain I should know never more.”
To her father’s hall the maiden she went, And through her left side a sharp pain was sent.
“Oh! make my bed, mother, in haste, mother dear, I shall in the fields no more wander this year.”
“And speak such words, daughter, dear daughter, no more; Thou shalt wed with a king ere twelvemonths are o’er.”
“Oh! better that I be in Heaven a bride, Than remain on the earth amid kingly pride.
“And father, dear father, go fetch me a priest, For I know that, ere long, death will be my guest.
“And brother, dear brother, go get me a bier; And sister, dear sister, do thou dress my hair.”
The maiden, she died, and was laid on her bier, And all her hand-maidens they plaited her hair.
They carried her out from her father’s hall door; And the angels of God with lights went before.
They carried the corpse to the churchyard along, And the angels of God went before with a song.
They buried the maiden beneath the dark sod, On midsummer morning:— And her coming was even well pleasing to God; In Heaven there is great joy, O!
A WALK IN A WORKHOUSE.
A few Sundays ago, I formed one of the congregation assembled in the chapel of a large metropolitan Workhouse. With the exception of the clergyman and clerk, and a very few officials, there were none but paupers present. The children sat in the galleries; the women in the body of the chapel, and in one of the side aisles; the men in the remaining aisle. The service was decorously performed, though the sermon might have been much better adapted to the comprehension and to the circumstances of the hearers. The usual supplications were offered, with more than the usual significancy in such a place, for the fatherless children and widows, for all sick persons and young children, for all that were desolate and oppressed, for the comforting and helping of the weak-hearted, for the raising-up of them that had fallen; for all that were in danger, necessity, and tribulation. The prayers of the congregation were desired “for several persons in the various wards, dangerously ill;” and others who were recovering returned their thanks to Heaven.
Among this congregation, were some evil-looking young women, and beetle-browed young men; but not many—perhaps that kind of characters kept away. Generally, the faces (those of the children excepted) were depressed and subdued, and wanted colour. Aged people were there, in every variety. Mumbling, blear-eyed, spectacled, stupid, deaf, lame; vacantly winking in the gleams of sun that now and then crept in through the open doors, from the paved yard; shading their listening ears, or blinking eyes, with their withered hands; poring over their books, leering at nothing, going to sleep, crouching and drooping in corners. There were weird old women, all skeleton within, all bonnet and cloak without, continually wiping their eyes with dirty dusters of pocket-handkerchiefs; and there were ugly old crones, both male and female, with a ghastly kind of contentment upon them which was not at all comforting to see. Upon the whole, it was the dragon, Pauperism, in a very weak and impotent condition; toothless, fangless, drawing his breath heavily enough, and hardly worth chaining up.
When the service was over, I walked with the humane and conscientious gentleman whose duty it was to take that walk, that Sunday morning, through the little world of poverty enclosed within the workhouse walls. It was inhabited by a population of some fifteen hundred or two thousand paupers, ranging from the infant newly born or not yet come into the pauper world, to the old man dying on his bed.
In a room opening from a squalid yard, where a number of listless women were lounging to and fro, trying to get warm in the ineffectual sunshine of the tardy May morning—in the “Itch-Ward,” not to compromise the truth—a woman such as HOGARTH has often drawn, was hurriedly getting on her gown, before a dusty fire. She was the nurse, or wardswoman, of that insalubrious department—herself a pauper—flabby, raw-boned, untidy—unpromising and coarse of aspect as need be. But, on being spoken to about the patients whom she had in charge, she turned round, with her shabby gown half on, half off, and fell a crying with all her might. Not for show, not querulously, not in any mawkish sentiment, but in the deep grief and affliction of her heart; turning away her dishevelled head: sobbing most bitterly, wringing her hands, and letting fall abundance of great tears, that choked her utterance. What was the matter with the nurse of the itch-ward? Oh, “the dropped child” was dead! Oh, the child that was found in the street, and she had brought up ever since, had died an hour ago, and see where the little creature lay, beneath this cloth! The dear, the pretty dear!
The dropped child seemed too small and poor a thing for Death to be in earnest with, but Death had taken it; and already its diminutive form was neatly washed, composed, and stretched as if in sleep upon a box. I thought I heard a voice from Heaven saying, It shall be well for thee, O nurse of the itch-ward, when some less gentle pauper does those offices to thy cold form, that such as the dropped child are the angels who behold my Father’s face!
In another room, were several ugly old women crouching, witch-like, round a hearth, and chattering and nodding, after the manner of the monkies. “All well here? And enough to eat?” A general chattering and chuckling; at last an answer from a volunteer. “Oh yes gentleman! Bless you gentleman! Lord bless the parish of St. So-and-So! It feed the hungry, Sir, and give drink to the thirsty, and it warm them which is cold, so it do, and good luck to the parish of St. So-and-So, and thankee gentleman!” Elsewhere, a party of pauper nurses were at dinner. “How do _you_ get on?” “Oh pretty well Sir! We works hard, and we lives hard—like the sodgers!”
In another room, a kind of purgatory or place of transition, six or eight noisy mad-women were gathered together, under the superintendence of one sane attendant. Among them was a girl of two or three and twenty, very prettily dressed, of most respectable appearance, and good manners, who had been brought in from the house where she had lived as domestic servant (having, I suppose, no friends), on account of being subject to epileptic fits, and requiring to be removed under the influence of a very bad one. She was by no means of the same stuff, or the same breeding, or the same experience, or in the same state of mind, as those by whom she was surrounded; and she pathetically complained that the daily association and the nightly noise made her worse, and was driving her mad—which was perfectly evident. The case was noted for enquiry and redress, but she said she had already been there for some weeks.
