And it becomes the moralist, too, to inquire what man might do to improve and beautify the system; what to make the stars shine more brightly, the sun more cheery and joyous, the moon more placid and content. Could he not heighten the tints of flowers and the melody of birds? Does he perform his duty to the inferior races? Should he not be a god to them? What is the part of magnanimity to the whale and the beaver? Should we not fear to exchange places with them for a day, lest by their behavior they should shame us? Might we not treat with magnanimity the shark and the tiger, not descend to meet them on their own level, with spears of shark’s teeth and bucklers of tiger’s skin? We slander the hyena; man is the fiercest and cruelest animal. Ah! he is of little faith; even the erring comets and meteors would thank him, and return his kindness in their kind.
How meanly and grossly do we deal with nature! Could we not have a less gross labor? What else do these fine inventions suggest,—magnetism, the daguerreotype, electricity? Can we not do more than cut and trim the forest?—can we not assist in its interior economy, in the circulation of the sap? Now we work superficially and violently. We do not suspect how much might be done to improve our relation to animated nature even; what kindness and refined courtesy there might be.
There are certain pursuits which, if not wholly poetic and true, do at least suggest a nobler and finer relation to nature than we know. The keeping of bees, for instance, is a very slight interference. It is like directing the sunbeams. All nations, from the remotest antiquity, have thus fingered nature. There are Hymettus and Hybla, and how many beerenowned spots beside! There is nothing gross in the idea of these little herds,—their hum like the faintest low of kine in the meads. A pleasant reviewer has lately reminded us that in some places they are led out to pasture where the flowers are most abundant. “Columella tells us,” says he, “that the inhabitants of Arabia sent their hives into Attica to benefit by the later-blowing flowers.” Annually are the hives, in immense pyramids, carried up the Nile in boats, and suffered to float slowly down the stream by night, resting by day, as the flowers put forth along the banks; and they determine the richness of any locality, and so the profitableness of delay, by the sinking of the boat in the water. We are told, by the same reviewer, of a man in Germany, whose bees yielded more honey than those of his neighbors, with no apparent advantage; but at length he informed them, that he had turned his hives one degree more to the east, and so his bees, having two hours the start in the morning, got the first sip of honey. True, there is treachery and selfishness behind all this, but these things suggest to the poetic mind what might be done.
Many examples there are of a grosser interference, yet not without their apology. We saw last summer, on the side of a mountain, a dog employed to churn for a farmer’s family, traveling upon a horizontal wheel, and though he had sore eyes, an alarming cough, and withal a demure aspect, yet their bread did get buttered for all that. Undoubtedly, in the most brilliant successes, the first rank is always sacrificed. Much useless traveling of horses, in extenso, has of late years been improved for man’s behoof, only two forces being taken advantage of,—the gravity of the horse, which is the centripetal, and his centrifugal inclination to go ahead. Only these two elements in the calculation. And is not the creature’s whole economy better economized thus? Are not all finite beings better pleased with motions relative than absolute? And what is the great globe itself but such a wheel,—a larger tread-mill,—so that our horse’s freest steps over prairies are oftentimes balked and rendered of no avail by the earth’s motion on its axis? But here he is the central agent and motive-power; and, for variety of scenery, being provided with a window in front, do not the ever-varying activity and fluctuating energy of the creature himself work the effect of the most varied scenery on a country road? It must be confessed that horses at present work too exclusively for men, rarely men for horses; and the brute degenerates in man’s society.
It will be seen that we contemplate a time when man’s will shall be law to the physical world, and he shall no longer be deterred by such abstractions as time and space, height and depth, weight and hardness, but shall indeed be the lord of creation. “Well,” says the faithless reader, “‘life is short, but art is long;’ where is the power that will effect all these changes?” This it is the very object of Mr. Etzler’s volume to show. At present, he would merely remind us that there are innumerable and immeasurable powers already existing in nature, unimproved on a large scale, or for generous and universal ends, amply sufficient for these purposes. He would only indicate their existence, as a surveyor makes known the existence of a water-power on any stream; but for their application he refers us to a sequel to this book, called the “Mechanical System.” A few of the most obvious and familiar of these powers are the Wind, the Tide, the Waves, the Sunshine. Let us consider their value.
First, there is the power of the Wind, constantly exerted over the globe. It appears from observation of a sailing-vessel, and from scientific tables, that the average power of the wind is equal to that of one horse for every one hundred square feet. We do not attach much value to this statement of the comparative power of the wind and horse, for no common ground is mentioned on which they can be compared. Undoubtedly, each is incomparably excellent in its way, and every general comparison made for such practical purposes as are contemplated, which gives a preference to the one, must be made with some unfairness to the other. The scientific tables are, for the most part, true only in a tabular sense. We suspect that a loaded wagon, with a light sail, ten feet square, would not have been blown so far by the end of the year, under equal circumstances, as a common racer or dray horse would have drawn it. And how many crazy structures on our globe’s surface, of the same dimensions, would wait for dry-rot if the traces of one horse were hitched to them, even to their windward side? Plainly this is not the principle of comparison. But even the steady and constant force of the horse may be rated as equal to his weight at least. Yet we should prefer to let the zephyrs and gales bear, with all their weight, upon our fences, than that Dobbin, with feet braced, should lean ominously against them for a season.
Nevertheless, here is an almost incalculable power at our disposal, yet how trifling the use we make of it! It only serves to turn a few mills, blow a few vessels across the ocean, and a few trivial ends besides. What a poor compliment do we pay to our indefatigable and energetic servant!
Men having discovered the power of falling water, which, after all, is comparatively slight, how eagerly do they seek out and improve these privileges! Let a difference of but a few feet in level be discovered on some stream near a populous town, some slight occasion for gravity to act, and the whole economy of the neighborhood is changed at once. Men do indeed speculate about and with this power as if it were the only privilege. But meanwhile this aerial stream is falling from far greater heights with more constant flow, never shrunk by drought, offering mill-sites wherever the wind blows; a Niagara in the air, with no Canada side;—only the application is hard.
There are the powers, too, of the Tide and Waves, constantly ebbing and flowing, lapsing and relapsing, but they serve man in but few ways. They turn a few tide-mills, and perform a few other insignificant and accidental services only. We all perceive the effect of the tide; how imperceptibly it creeps up into our harbors and rivers, and raises the heaviest navies as easily as the lightest chip. Everything that floats must yield to it. But man, slow to take nature’s constant hint of assistance, makes slight and irregular use of this power, in careening ships and getting them afloat when aground.
This power may be applied in various ways. A large body, of the heaviest materials that will float, may first be raised by it, and being attached to the end of a balance reaching from the land, or from a stationary support fastened to the bottom, when the tide falls the whole weight will he brought to bear upon the end of the balance. Also, when the tide rises, it may be made to exert a nearly equal force in the opposite direction. It can be employed wherever a poi
nt d’appui can be obtained.
Verily, the land would wear a busy aspect at the spring and neap tide, and these island ships, these terrae infirmae, which realize the fables of antiquity, affect our imagination. We have often thought that the fittest locality for a human dwelling was on the edge of the land, that there the constant lesson and impression of the sea might sink deep into the life and character of the landsman, and perhaps impart a marine tint to his imagination. It is a noble word, that mariner,—one who is conversant with the sea. There should be more of what it signifies in each of us. It is a worthy country to belong to,—we look to see him not disgrace it. Perhaps we should be equally mariners and terreners, and even our Green Mountains need some of that sea-green to be mixed with them.
The computation of the power of the Waves is less satisfactory. While only the average power of the wind and the average height of the tide were taken before, now the extreme height of the waves is used, for they are made to rise ten feet above the level of the sea, to which, adding ten more for depression, we have twenty feet, or the extreme height of a wave. Indeed, the power of the waves, which is produced by the wind blowing obliquely and at disadvantage upon the water, is made to be, not only three thousand times greater than that of the tide, but one hundred times greater than that of the wind itself, meeting its object at right angles. Moreover, this power is measured by the area of the vessel, and not by its length mainly, and it seems to be forgotten that the motion of the waves is chiefly undulatory, and exerts a power only within the limits of a vibration, else the very continents, with their extensive coasts, would soon be set adrift.
Finally, there is the power to be derived from Sunshine, by the principle on which Archimedes contrived his burning-mirrors, a multiplication of mirrors reflecting the rays of the sun upon the same spot, till the requisite degree of heat is obtained. The principal application of this power will be to the boiling of water and production of steam. So much for these few and more obvious powers, already used to a trifling extent. But there are innumerable others in nature, not described nor discovered. These, however, will do for the present. This would be to make the sun and the moon equally our satellites. For, as the moon is the cause of the tides, and the sun the cause of the wind, which, in turn, is the cause of the waves, all the work of this planet would be performed by these far influences.
“We may store up water in some eminent pond, and take out of this store, at any time, as much water through the outlet as we want to employ, by which means the original power may react for many days after it has ceased … . Such reservoirs of moderate elevation or size need not be made artificially, but will be found made by nature very frequently, requiring but little aid for their completion. They require no regularity of form. Any valley, with lower grounds in its vicinity, would answer the purpose. Small crevices may be filled up. Such places may be eligible for the beginning of enterprises of this kind.”
The greater the height, of course, the less water required. But suppose a level and dry country; then hill and valley, and “eminent pond,” are to be constructed by main force; or, if the springs are unusually low, then dirt and stones may be used, and the disadvantage arising from friction will be counterbalanced by their greater gravity. Nor shall a single rood of dry land be sunk in such artificial ponds as may be wanted, but their surfaces “may be covered with rafts decked with fertile earth, and all kinds of vegetables which may grow there as well as anywhere else.”
And, finally, by the use of thick envelopes retaining the heat, and other contrivances, “the power of steam caused by sunshine may react at will, and thus be rendered perpetual, no matter how often or how long the sunshine may be interrupted.”
Here is power enough, one would think, to accomplish somewhat. These are the Powers below. O ye millwrights, ye engineers, ye operatives and speculators of every class, never again complain of a want of power: it is the grossest form of infidelity. The question is, not how we shall execute, but what. Let us not use in a niggardly manner what is thus generously offered.
Consider what revolutions are to be effected in agriculture. First, in the new country a machine is to move along, taking out trees and stones to any required depth, and piling them up in convenient heaps; then the same machine, “with a little alteration,” is to plane the ground perfectly, till there shall be no hills nor valleys, making the requisite canals, ditches, and roads as it goes along. The same machine, “with some other little alterations,” is then to sift the ground thoroughly, supply fertile soil from other places if wanted, and plant it; and finally the same machine, “with a little addition,” is to reap and gather in the crop, thresh and grind it, or press it to oil, or prepare it any way for final use. For the description of these machines we are referred to “Etzler’s Mechanical System,” pages 11 to 27. We should be pleased to see that “Mechanical System.” We have great faith in it. But we cannot stop for applications now.
Who knows but by accumulating the power until the end of the present century, using meanwhile only the smallest allowance, reserving all that blows, all that shines, all that ebbs and flows, all that dashes, we may have got such a reserved accumulated power as to run the earth off its track into a new orbit, some summer, and so change the tedious vicissitude of the seasons? Or, perchance, coming generations will not abide the dissolution of the globe, but, availing themselves of future inventions in aerial locomotion, and the navigation of space, the entire race may migrate from the earth, to settle some vacant and more western planet, it may be still healthy, perchance unearthy, not composed of dirt and stones, whose primary strata only are strewn, and where no weeds are sown. It took but little art, a simple application of natural laws, a canoe, a paddle, and a sail of matting, to people the isles of the Pacific, and a little more will people the shining isles of space. Do we not see in the firmament the lights carried along the shore by night, as Columbus did? Let us not despair nor mutiny.
“The dwellings also ought to be very different from what is known, if the full benefit of our means is to be enjoyed. They are to be of a structure for which we have no name yet. They are to be neither palaces, nor temples, nor cities, but a combination of all, superior to whatever is known.
“Earth may be baked into bricks, or even vitrified stone by heat,—we may bake large masses of any size and form, into stone and vitrified substance of the greatest durability, lasting even thousands of years, out of clayey earth, or of stones ground to dust, by the application of burning-mirrors. This is to be done in the open air without other preparation than gathering the substance, grinding and mixing it with water and cement, moulding or casting it, and bringing the focus of the burning-mirrors of proper size upon the same.”
The character of the architecture is to be quite different from what it ever has been hitherto; large solid masses are to be baked or cast in one piece, ready shaped in any form that may be desired. The building may, therefore, consist of columns two hundred feet high and upwards, of proportionate thickness, and of one entire piece of vitrified substance; huge pieces are to be moulded so as to join and hook on to each other firmly, by proper joints and folds, and not to yield in any way without breaking.
“Foundries, of any description, are to be heated by burning-mirrors, and will require no labor, except the making of the first moulds and the superintendence for gathering the metal and taking the finished articles away.”
Alasl in the present state of science, we must take the finished articles away; but think not that man will always be the victim of circumstances.
The countryman who visited the city, and found the streets cluttered with bricks and lumber, reported that it was not yet finished; and one who considers the endless repairs and reforming of our houses might well wonder when they will be done. But why may not the dwellings of men on this earth be built, once for all, of some durable material, some Roman or Etruscan masonry, which will stand, so that time shall only adorn and beautify them? Why may we not finish the outward world for posterity, a
nd leave them leisure to attend to the inner? Surely, all the gross necessities and economies might be cared for in a few years. All might be built and baked and stored up, during this, the term-time of the world, against the vacant eternity, and the globe go provisioned and furnished, like our public vessels, for its voyage through space, as through some Pacific Ocean, while we would “tie up the rudder and sleep before the wind,” as those who sail from Lima to Manilla.
But, to go back a few years in imagination, think not that life in these crystal palaces is to bear any analogy to life in our present humble cottages. Far from it. Clothed, once for all, in some “flexible stuff,” more durable than George Fox’s suit of leather, composed of “fibres of vegetables,” “glutinated” together by some “cohesive substances,” and made into sheets, like paper, of any size or form, man will put far from him corroding care and the whole host of ills.
“The twenty-five halls in the inside of the square are to be each two hundred feet square and high; the forty corridors, each one hundred feet long and twenty wide; the eighty galleries, each from 1,000 to 1,250 feet long; about 7,000 private rooms, the whole surrounded and intersected by the grandest and most splendid colonnades imaginable; floors, ceilings, columns, with their various beautiful and fanciful intervals, all shining, and reflecting to infinity all objects and persons, with splendid lustre of all beautiful colors, and fanciful shapes and pictures.
“All galleries, outside and within the halls, are to be provided with many thousand commodious and most elegant vehicles, in which persons may move up and down like birds, in perfect security, and without exertion … . Any member may procure himself all the common articles of his daily wants, by a short turn of some crank, without leaving his apartment.
“One or two persons are sufficient to direct the kitchen business. They have nothing else to do but to superintend the cookery, and to watch the time of the victuals being done, and then to remove them, with the table and vessels, into the dining-hall, or to the respective private apartments, by a slight motion of the hand at some crank … . Any very extraordinary desire of any person may be satisfied by going to the place where the thing is to be had; and anything that requires a particular preparation in cooking or baking may be done by the person who desires it.”
Walden by Henry David Thoreau Page 11
