In England every body notices the weather, and talks about the weather, and suffers by the weather, yet very few of us know any thing about it. The changes of our climate have given us a constant and an insatiable national disease – consumption; the density of our winter fog has gained an European celebrity; while the general haziness of our atmosphere induces an Italian or an American to doubt whether we are ever indulged with a real blue sky. "Good day" has become the national salutation; umbrellas, water-proof clothes, and cough mixtures are almost necessities of English life; yet, despite these daily and hourly proofs of the importance of the weather to each and all of us, it is only within the last ten years that any effectual steps have been taken in England to watch the weather and the proximate elements which regulate its course and variations.
Yet, in those ten years positive wonders have been done, and good hope established that a continuance of patient inquiry will be rewarded by still further discoveries. To take a single result, it may be mentioned, that a careful study of the thermometer has shown that a descent of the temperature of London from forty-five to thirty-two degrees, generally kills about 300 persons. They may not all die in the very week when the loss of warmth takes place, but the number of deaths is found to increase to that extent over the previous average within a short period after the change. The fall of temperature, in truth, kills them as certainly as a well-aimed cannon-shot. Our changing climate, or deficient food and shelter, has prepared them for the final stroke, but they actually die at last of the weather.
Before 1838, several European states, less apt than ourselves to talk about the weather, had taken it up as a study, and had made various contributions to the general knowledge of the subject; but in that year England began to act. The officials who now and then emerge from the Admiralty under the title of the "Board of Visitors," to see what is in progress at the Greenwich Observatory, were reminded by Mr. Airy, the astronomer royal, that much good might be done by pursuing a course of magnetic and meteorological observations. The officials "listened and believed."
The following year saw a wooden fence pushed out behind the Observatory walls, in the direction of Blackheath, and soon afterward a few low-roofed, unpainted, wooden buildings were dotted over the inclosure. These structures are small enough and humble enough to outward view, yet they contain some most beautifully-constructed instruments, and have been the scene of a series of observations and discoveries of the greatest interest and value. The stray holiday visitor to Greenwich Park, who feels tempted to look over the wooden paling, sees only a series of deal sheds, upon a rough grass-plat; a mast some eighty feet high, steadied by ropes, and having a lantern at the top, and a windlass below; and if he looks closer, he perceives a small inner inclosure, surrounded by a dwarf fence; an upright stand, with a movable top, sheltering a collection of thermometers; and here and there a pile of planks and unused partitioning, that helps to give the place an appearance of temporary expediency, an aspect something between a collection of emigrants' cottages and the yard of a dealer in second-hand building materials. But – as was said when speaking of the Astronomical Observatory – Greenwich is a practical place, and not one prepared for show. Science, like virtue, does not require a palace for a dwelling-place. In this collection of deal houses, during the last ten years, Nature has been constantly watched, and interrogated with the zeal and patience which alone can glean a knowledge of her secrets. And the results of those watches, kept at all hours, and in all weathers, are curious in the extreme; but before we ask what they are, let us cross the barrier, and see with what tools the weather-students work.
The main building is built in the form of a cross, with its chief front to the magnetic north. It is formed of wood, all iron and other metals being carefully excluded; for its purpose is to contain three large magnets, which have to be isolated from all influence likely to interfere with their truthful action. In three arms of the cross these magnets are suspended by bands of unwrought, untwisted silk. In the fourth arm is a sort of double window, filled with apparatus for receiving the electricity collected at the top of the mast which stands close by. Thus, in this wooden shed, we find one portion devoted to; electricity – to the detection and registry of the stray lightning of the atmosphere – and the other three to a set of instruments that feel the influence and register the variations of the magnetic changes in the conditions of the air. "True as the needle to the pole," is the burden of an old song, which now shows how little our forefathers knew about this same needle, which, in truth, has a much steadier character than it deserves. Let all who still have faith in the legend go to the magnet-house, and when they have seen the vagaries there displayed, they will have but a poor idea of Mr. Charles Dibdin's sea-heroes, whose constancy is declared to have been as true as their compasses were to the north.
Upon entering the magnet-house, the first object that attracts attention are the jars to which the electricity is brought down. The fluid is collected, as just stated, by a conductor running from the top of the mast outside. In order that not the slightest portion may be lost in its progress down, a lamp is kept constantly burning near the top of the pole, the light of which keeps warm and dry a body of glass that cuts off all communication between the conductor and the machinery which supports it. Another light, for the purpose of collecting the electricity by its flame, is placed above the top of the pole. This light, burning at night, has given rise to many a strange supposition in the neighborhood. It is too high up to be serviceable as a lantern to those below. Besides, who walks in Greenwich Park after the gates are closed? It can light only the birds or the deer. "Then, surely," says another popular legend, "it is to guide the ships on the river, when on their way up at night; a sort of landmark to tell where-abouts the Observatory is when the moon and stars are clouded, and refuse to show where their watchers are."
All these speculations are idle, for the lights burn when the sun is shining, as well as at night; and the object of the lower one is that no trace of moisture, and no approach of cold, shall give the electricity a chance of slipping down the mast, or the ropes, to the earth, but shall leave it no way of escape from the wise men below, who want it, and will have it, whether it likes or no, in their jars, that they may measure its quantity and its quality, and write both down in their journals. It is thus that electricity comes down the wires into those jars on our right as we enter. If very slight, its presence there is indicated by tiny morsels of pendent gold-leaf; if stronger, the divergence of two straws show it; if stronger still, the third jar holds its greater force, while neighboring instruments measure the length of the electric sparks, or mark the amount of the electric force. At the desk, close by, sits the observer, who jots down the successive indications. In his book he registers from day to day, throughout the year, how much electricity has been in the air, and what was its character, even to such particulars as to whether its sparks were blue, violet, or purple in color. At times, however, he has to exercise great care, and it is not always that he even then escapes receiving severe shocks.
Passing on, we approach the magnets. They are three in number; of large size, and differently suspended, to show the various ways in which such bodies are acted upon. All hang by bands of unwrought silk. If the silk were twisted, it would twist the magnets, and the accuracy of their position would be disturbed. Magnets, like telescopes, must be true in their adjustment to the hundredth part of a hair's breadth. One magnet hangs north and south; another east and west; and a third, like a scale-beam, is balanced on knife-edges and agate planes, so beautifully, that when once adjusted and inclosed in its case, it is opened only once a year, lest one grain of dust, or one small spider, should destroy its truth; for spiders are as troublesome to the weather-student as to the astronomer. These insects like the perfect quiet that reigns about the instruments of the philosopher, and with heroic perseverance persist in spinning their fine threads among his machines. Indeed, spiders occasionally betray the magnetic observer into very odd behavior At times he may be seen bowing in the sunshine, like a Persian fire-worshiper; now stooping in this direction, now dodging in that, but always gazing through the sun's rays up toward that luminary. He seems demented, staring at nothing. At last he lifts his hand; he snatches apparently at vacancy to pull nothing down In truth his eye had at last caught the gleam of light reflected from an almost invisible spider line running from the electrical wire to the neighboring planks. The spider who had ventured on the charged wire paid the penalty of such daring with his life long ago, but he had left his web behind him, and that beautifully minute thread has been carrying off to the earth a portion of the electric fluid, before it had been received, and tested, and registered by the mechanism below. Such facts show the exceeding delicacy of the observations.
For seven years, the magnets suspended in this building were constantly watched every two hours – every even hour – day and night, except on Sundays, the object being that some light might be thrown upon the laws regulating the movements of the mariner's compass; hence, that while men became wiser, navigation might be rendered safer. The chief observer – the genius loci– is Mr. Glaisher, whose name figures in the reports of the Register-General. He, with two assistants, from year to year, went on making these tedious examinations of the variations of the magnets, by means of small telescopes, fixed with great precision upon pedestals of masonry or wood fixed on the earth, and unconnected with the floor of the building, occupying a position exactly between the three magnets. This mode of proceeding had continued for some years with almost unerring regularity, and certain large quarto volumes full of figures were the results, when an ingenious medical man, Mr. Brooke, hit upon a photographic plan for removing the necessity for this perpetual watchfulness. Now, in the magnet-house, we see light and chemistry doing the tasks before performed by human labor; and doing them more faithfully than even the most vigilant of human eyes and hands. Around the magnets are cases of zinc, so perfect that they exclude all light from without. Inside those cases, in one place, is a lamp giving a single ray of prepared light, which, falling upon a mirror soldered to the magnet, moves with its motions. This wandering ray, directed toward a sheet of sensitive photographic paper, records the magnet's slightest motion! The paper moves on by clock-work, and once in four-and-twenty hours an assistant, having closed the shutters of the building, lights a lantern of yellow glass, opens the magnet-boxes, removes the paper on which the magnets have been enabled to record their own motions, and then, having put in a fresh sheet of sensitive paper, he shuts it securely in, winds up the clock-work, puts out his yellow light, and lets in the sunshine. His lantern glass is yellow, because the yellow rays are the only ones which can be safely allowed to fall upon the photographic paper during its removal from the instrument, to the dish in which its magnetic picture is to be fixed by a further chemical process. It is the blue ray of the light that gives the daguerrotypic likeness – as most persons who have had their heads off, under the hands of M. Claudet, or Mr. Beard, or any of their numerous competitors in the art of preparing sun-pictures, well know.
Since the apparatus of Mr. Brooke for the self-registration of the magnetic changes has been in operation at Greenwich, the time of Mr. Glaisher and his assistants has been more at liberty for other branches of their duties. These are numerous enough. Thermometers and barometers have to be watched as well as magnets. To these instruments the same ingenious photographic contrivance is applied.
The wooden building next to the magnet-house on the southwest contains a modification of Mr. Brooke's ingenious plan, by which the rise and fall of the temperature of the air is self-registered. Outside the building are the bulbs of thermometers freely exposed to the weather. Their shafts run through a zinc case, and as the mercury rises or falls, it moves a float having a projecting arm. Across this arm is thrown the ray of prepared light which falls then upon the sensitive paper. Thus we see the variations of the needle and the variations in heat and cold both recording their own story, within these humble-looking wooden sheds, as completely as the wind and the rain are made to do the same thing, on the top of the towers of the Observatory. The reward given to the inventor of this ingenious mode of self-registration has been recently revealed in a parliamentary paper, thus: "To Mr. Charles Brooke for his invention and establishment at the Royal Observatory, of the apparatus for the self-registration of magnetical and meteorological phenomena, £500." Every year the invention will save fully £500 worth of human toil; and the reward seems small when we see every year millions voted for warlike, sinecure, and other worse than useless purposes.
Photography, however, can not do all the work. Its records have to be cheeked by independent observations every day, and then both have to be brought to their practical value by comparison with certain tables which test their accuracy, and make them available for disclosing certain scientific results. The preparation of such tables is one of the practical triumphs of Greenwich. Many a quiet country gentleman amuses his leisure by noting day by day the variations of his thermometer and barometer. Heretofore such observations were isolated and of no general value, but now, by the tables completed by Mr. Glaisher, and published by the Royal Society, they may all be converted into scientific values, and be made available for the increase of our weather-wisdom. For nearly seventy years the Royal Society had observations made at Somerset House, but they were a dead letter – mere long columns of figures – till these tables gave them significance. And the same tables now knit into one scientific whole, the observations taken by forty scientific volunteers, who, from day to day, record for the Registrar-General of births and deaths, the temperature, moisture, &c., of their different localities, which vary from Glasgow to Guernsey, and from Cornwall to Norwich.
What the Rosetta stone is to the history of the Pharaohs, these Greenwich tables have been to the weather-hieroglyphics. They have afforded something like a key to the language in which the secrets are written; and it remains for industrious observation and scientific zeal to complete the modern victory over ancient ignorance. Already the results of the Greenwich studies of the weather have given us a number of curious morsels of knowledge. The wholesale destruction of human life induced by a fall in the temperature of London has just been noticed. Besides the manifestation of that fact, we are shown, that instead of a warm summer being followed by a cold winter, the tendency of the law of the weather is to group warm seasons together, and cold seasons together. Mr. Glaisher has made out, that the character of the weather seems to follow certain curves, so to speak, each extending over periods of fifteen years. During the first half of each of these periods, the seasons become warmer and warmer, till they reach their warmest point, and then they sink again, becoming colder and colder, till they reach the lowest point, whence they rise again. His tables range over the last seventy-nine years – from 1771 to 1849. Periods shown to be the coldest, were years memorable for high-priced food, increased mortality, popular discontent, and political changes. In his diagrams, the warm years are tinted brown, and the cold years gray, and as the sheets are turned over and the dates scanned, the fact suggest itself that a gray period saw Lord George Gordon's riots; a gray period was marked by the Reform Bill excitement; and a gray period saw the Corn Laws repealed.
A few more morsels culled from the experience of these weather-seers, and we have done.
Those seasons have been best which have enjoyed an average temperature – not too hot nor too cold.
The indications are that the climate of England is becoming warmer, and, consequently, healthier; a fact to be partly accounted for by the improved drainage and the removal of an excess of timber from the land.
The intensity of cholera was found greatest in those places where the air was stagnant; and, therefore, any means for causing its motion, as lighting fires and improving ventilation, are thus proved to be of the utmost consequence.
Some day near the 20th of January – the lucky guess, in 1838, of Murphy's Weather Almanac – will, upon the average of years, be found to be the coldest of the whole year.
In the middle of May there are generally some days of cold, so severe as to be unexplainable. Humboldt mentions this fact in his Cosmos; and various authors have tried to account for it – at present in vain. The favorite notion, perhaps, is that which attributes this period of cold to the loosening of the icebergs of the north. Another weather eccentricity is the usual advent of some warm days at the beginning of November.
Certain experiments in progress to test the difference between the temperature of the Thames, and of the surrounding atmosphere, are expected to show the cause of the famous London fog. During the night the Thames is often from ten to seventeen degrees warmer, and in the day time from eight to ten degrees colder than the air above it.
If the theory of weather-cycles holds good, we are to have seasons colder than the average from this time till 1853, when warmth will begin again to predominate over cold. A chilly prophecy this to close with, and therefore, rather let an anecdote complete this chapter on the Weather-Watchers of Greenwich.
Among other experiments going on some time ago in the observatory inclosure, were some by which Mr. Glaisher sought to discover how much warmth the earth lost during the hours of night, and how much moisture the air would take up in a day from a given surface. Upon the long grass, within the dwarf fence already mentioned were placed all sorts of odd substances, in little distinct qualities. Ashes wood, leather, linen, cotton, glass, lead, copper and stone, among other things, were there to show how each affected the question of radiation. Close by upon a post was a dish six inches across, in which every day there was punctually poured one ounce of water, and at the same hour next day, as punctually was this fluid remeasured to see what had been lost by evaporation. For three years this latter experiment had been going on, and the results were posted up in a book; but the figures gave most contradictory results. There was either something very irregular in the air, or something very wrong in the apparatus. It was watched for leakage, but none was found, when one day Mr. Glaisher stepped out of the magnet-house, and looking toward the stand, the mystery was revealed. The evaporating dish of the philosopher was being used as a bath by an irreverent bird! a sparrow was scattering from his wings the water left to be drunk by the winds of Heaven. Only one thing remained to be done; and the next minute saw a pen run through the tables that had taken three years to compile. The labor was lost – the work had to be begun again.
DOING
Oh, friend, whoe'er thou art, who dost rejoice
In the sweet tones of thy melodious voice;
Which to thy fancy are so rich and clear,
Falling like music, on the list'ning ear,
Of thee I ask,
What hast thou done of that thou hast to do?
Art silent? Then I say,
Until thy deeds are many let thy words be few.
Oh, man, whoe'er thou art, within whose breast
The glowing thoughts disdain ignoble rest;
Whose soul is laboring with a monstrous birth
Of winged words, to scatter through the earth
Of thee I ask,
What hast thou done of that thou hast to do?
Art silent? Then I say,
Until thy deeds are many let thy words be few.
Oh, brother mine, who would'st reform mankind
Purging the dross, and leaving all refined;
Preaching of sinless love, sobriety,
Of goodness, endless peace, and charity,
Of thee I ask,
What hast thou done of that thou hast to do?
Art silent? Then I say,
Until thy deeds are many let thy words be few.
Speech without action is a moral dearth,
And to advance the world is little worth:
Let us think much, say little, and much do,
If to ourselves and God we will be true;
And ask within,
What have I done of that I have to do?
Is conscience silent – say,
Oh! let my deeds be many and my words be few.

YOUNG RUSSIA
Certain social theorists have, of late years, proclaimed themselves to the puzzled public under the name and signification of "Young." Young France, Young Germany, and Young England have had their day, and having now grown older, and by consequence wiser, are comparatively mute. In accordance with what seems a natural law, it is only when a fashion is being forgotten where it originated – in the west – that is reaches Russia, which rigidly keeps a century or so behind the rest of the Continent. It is only recently, therefore, that we hear of "Young Russia."
The main principles of all these national youths are alike. They are pleasingly picturesque – simperingly amiable; with a pretty and piquant dash of paradox. What they propose is not new birth, or dashing out into new systems, and taking advantage of new ideas; but reverting to old systems, and furbishing them up so as to look as good as new. Re-juvenescence is their aim; the middle ages their motto. Young England, to wit, desires to replace things as they were in the days of the pack-horse, the thumb-screw, the monastery, the ducking-stool, the knight errant, trial by battle, and the donjon-keep. To these he wishes to apply all possible modern improvements, to adapt them to present ideas, and to present events. Though he would have no objection to his mailed knight traveling per first-class railway, he would abolish luggage-trains to encourage intestine trade and the breed of that noble animal the pack-horse. He has, indeed, done something in this monastic line; but his efforts for the dissemination of superstition, and his denunciations of a certain sort of witchcraft, have signally failed. In truth, the task he has set himself – that of re-constructing society anew out of old materials – though highly archæological, historical, and poetic, has the fatal disadvantage of being simply impossible. It is telling the people of the nineteenth century to carry their minds, habits, and sentiments back, so as to become people of the thirteenth century; it is trying to make new muslin out of mummy cloth, or razors out of rusty nails.
"Young Russia" is an equal absurdity, but from a precisely opposite cause; for, indeed, this sort of youth out of age is a series of paradoxes. The Russian of the present day is the Russian of past ages. He exists by rule – the rule of despotism – which is as old as the Medes and Persians; and which forces him into an iron mould that shapes his appearance, his mind, and his actions to one pattern, from one generation to another Hence every thing that lives and breathes in Russia being antique, there is no appreciable antiquity. The new school, therefore – even if amateur politics were allowable in Russia, which they are not, as a large population of exiles in Siberia can testify – has no materials to work upon. Stagnation is the political law, and "Young Russia" dies in its babyhood for want of sustenance. What goes by the name of civilization, is no advance in wealth, morals, or social happiness. It is merely a tinsel coating over the rottenness and rust with which Russian life is "sicklied o'er." It has nothing to do with a single soul below the rank of a noble; and with him it means Champagne, bad pictures, Parisian tailors, operas, gaming, and other expenses and elegancies imported from the West. Hundreds of provincial noblemen are ruined every year in St. Petersburg, in undergoing this process of civilization. The fortunes thus wasted are enormous; yet there is only one railroad now in operation throughout the whole empire, and that belongs to the Emperor, and leads to one of his palaces a few miles from the capital. Such is Russian civilization. What then is "Young Russia" to do? Ask one of its youngest apostles, Ivan Vassilievitsch.
This young gentleman – for an introduction to whom we are indebted to Count Sollogub – was, not long ago, parading the Iverskoy boulevard – one of the thirteen which half encircle Moscow – when he met a neighbor from the province of Kazan. Ivan had lately returned from abroad. He was a perfect specimen of the new school, inside and out. Within, he had imbibed all the ideas of the juvenile or verdant schools of Germany, France, and England. Without, he displayed a London macintosh; his coat and trowsers had been designed and executed by Parisian artists; his hair was cut in the style of the middle ages; and his chin showed the remnants of a Vandyke beard. He also resembled the new school in another respect: he had spent all his money, yet he was separated from home by the distance of a long – a Russian – journey.
To meet with a neighbor – which he did – who traveled in his own carriage, in which he offered a seat, was the height of good fortune. The more so, as Ivan wished to see as much of Russian life on the road as possible, and to note down his impressions in a journal, whose white leaves were as yet unsullied with ink. From the information he intended to collect, he intended to commence helping to re-construct Russian society after the order of the new Russiaites.
The vehicle in which this great mission was to be performed, was a humble family affair called a Tarantas. After a series of adventures – but which did not furnish Ivan a single impression for his note-book – they arrive at Vladimir, the capital of a province or "government." Here the younger traveler meets with a friend, to whom he confides his intention of visiting all the other Government towns for "Young Russia" purposes. His friend's reply is dispiriting to the last degree.
