Having thus briefly traced the history of aeronautics, we shall now inquire into the practical value of the art.

After the discovery of the hydrogen-gas balloon, the most extravagant projects dazzled and bewildered the minds of men. To journey through the air from one part of the globe to another, or even to circumnavigate the globe itself, in balloons, was child's play, compared with the magnificent results that were anticipated. It was fondly expected that the new discovery would open up a channel of communication between the earth and its sister planets, and that the time was not far distant when men would be embarking from the Earth, in a balloon, for the Moon, or for Mercury, Venus, Mars, the Asteroids, or some of the other planets, just as they embarked in a ship for France, Italy, India, China, Africa, or America. They forgot that the laws of gravitation, which bind man as by chains of adamant to this world, would ever interpose an insurmountable obstacle to the realization of such wild imaginings; that the atmosphere has its limits as well as the ocean, extending, it is calculated, not much beyond forty miles above the earth's surface; that, at a certain height, it is as light, by reason of its rarity, as the lightest gas with which a balloon can be inflated, thereby rendering all farther ascent impossible; and that, even before the aeronaut had reached that height, very serious consequences would ensue from the intense cold, from the diminution of atmospheric pressure, and from the inadequacy of a too rarified atmosphere for supporting respiration. Such overwrought expectations, however, produced by the first excitement of a great discovery, soon subsided, when men began soberly to reflect on the immutable laws, or, which is the same thing, the powerful mandate of the Creator, which confines all things within their appointed sphere.

But though the idea of emigrating by means of balloons to foreign worlds was relinquished, there still existed a desire to render them subservient to important terrestrial purposes, and various suggestions were made as to the uses to which they might be applied. It was proposed to employ their power of ascension as a mechanical force for raising water from mines, for transporting obelisks, and placing them on greater elevations, or for raising, without any scaffolding a cross or a vane to the top of a high spire. It was proposed that they might be employed as a means of making an escape from surrounding icebergs in the ocean, or for effecting a landing to otherwise inaccessible mountains, and observing their cloud-capped peaks – for exploring the craters of volcanoes – for traversing vast swamps and morasses – and for the improvement of the infant science of meteorology. It was besides predicted that they would become a safe, easy, and expeditious mode of traveling, and of conveying the products of every land and clime from one part of the globe to another. It is long since Dr. Dick suggested, in his "Christian Philosopher," that the missionaries of the cross might yet be able to avail themselves of the aid of balloons in going forth to distant regions to proclaim to the heathen the unsearchable riches of Christ, and that then there would be a literal fulfillment of the prediction of the last of the inspired seers, "And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people." But to only two purposes has the ascending power of the balloon been as yet applied – to the reconnoitring of hostile armies, by the French, for a short time – and, in one or two instances, to the making of scientific observations. Only a single attempt, and a very absurd one, has been made to get up a traveling balloon. The gold-hunters of America, impatient of the slow process by which ships transport them to the golden regions of California, and, as if determined to press the air into the service of giving them a speedier conveyance, lately proposed to build a balloon, to carry them out at the rate of 200 miles per hour. A model of the machine was exhibited in New York and Philadelphia, and it created considerable sensation in the minds of the credulous. It was stated, in a respectable journal of New York, in 1849, that the machine was actually in course of construction, and the steam-engine finished, but nothing more has since been heard of it. "Had these projectors," says Mr. Wise, "gone on from their miniature model, to the erection of one capable of carrying one or two persons, in order to prove its practicability on a larger scale, there might have been reason to believe that they harbored an idea of its general usefulness. But when the project embraced at once so magnificent a scheme, as that contemplated in the swooping strides toward the modern Dorado, with a cargo of a hundred gold-hunters, it seemed too much for sober-minded people; and brought upon itself philosophical criticism and scientific condemnation, and, with that, a good share of opposition to the hopes and expectations of aerial navigation in any shape."

Aerostation is at present applied to no practical useful purpose; it is a mere plaything, occupying no higher a position than catchpenny mountebank exhibitions. Ascents are made in balloons from no other motive, or for no other object, than to draw money from the pockets of the multitude, by ministering to their enjoyment; and when made by persons properly acquainted with the principles and practice of the art – for by such alone can they be effected with safety – and with those precautions which experience has shown to be requisite, they might be liable to no great objection, so long as the people are willing to pay for them; but if conducted by unqualified persons, or by the most skillful, with a daring recklessness of personal danger, or in a manner involving suffering to any sentient being, they ought to be discouraged in every legitimate way by every friend of humanity, as at variance alike with the principles of morality and with the benevolent lessons of the Christian faith. No man may lawfully peril his own life, or subject the inferior animals to unnecessary pain, for the gratification of the all-devouring thirst of the public for exciting exhibitions; and in the very act of encouraging and witnessing such exhibitions, we are quenching the merciful and fostering the cruel in our natures. Of this objectionable character is the practice recently introduced into France of carrying up donkeys in balloons. The adventure is indeed no new one. It was performed by Mr. Green some twenty years ago. But the merit, or rather the demerit, of having turned it into one of the most popular shows in France, is due to M. Poitevin, who has lately been exciting the gaping admiration of thousands in Paris, by this fool-hardy, barbarous, and contemptible mode of aerostation. Early in July this year (1850), he ascended on horseback in a balloon from Champ de Mars, in the presence of upwards of 10,000 persons, who had paid for admission, and the President of the Republic was one of the spectators. The horse, a handsome dapple gray, had stout cloth placed round its body, and several straps, passed over the shoulders and loins, were united in rings, which were attached by cords to the network of the balloon. In this manner was the animal cruelly suspended in the air, having no resting-place for its feet, nor was there any thing to protect the rider, had he lost his balance or been thrown off. The feat having been more successful than could reasonably have been expected, Mr. Green proposed to amuse the inhabitants of London by a similar adventure. Some of the more humane of the English capital were shocked at the announcement; and the secretary of the Society for the Prevention of Cruelty to Animals made application on the 30th of July to the magistrates to put a stop to the ascent. A case of interference not having been made out to the satisfaction of the magistrates, Mr. Green next day started on his journey to the clouds mounted on a pony. It was put in the car – a plan more humane than that of M. Poitevin, who suspended his pony in the air. But the whole affair was a miserably poor one, and well fitted to bring all such experiments into contempt. The nag was not larger than an under-sized Newfoundland dog; and what made the thing more ridiculous still, the poor creature – which, by the way, had its eyes bandaged, and was strongly tied by cords to the network of the balloon – was so feeble that, on mounting it, Mr. Green had to sustain his own weight by a pile of sand bags placed on either side. This sham equestrian excursion through the air appears to have generally disappointed onlookers, and pony ascensions have not been attempted a second time in England. In France they have met with greater favor. They have been repeated by M. Poitevin and others in the presence of immense multitudes: and it should not be passed over without remark, as one proof among others of what the animals suffer, and, consequently, of the cruelty of the practice, that, in some of these instances, blood flowed from their ears and nostrils. That the practice is dangerous to the aeronaut as well as cruel to the animal, has been the judgment of all reflecting men from the first; and the late melancholy fate of Lieutenant Gale, an English, naval officer, who ascended from the Hippodrome of Vincennes, near Bordeaux, on Sabbath – a very unsuitable day, surely, for such exhibitions – the 8th of September last, mounted on a horse, which was suspended beneath the car of the balloon by girths passed under its body, reads a lesson to which it would be wise to listen. By the aid of several peasants who were in the fields, he effected his descent without any accident to himself or the horse; but, having unfastened the animal, he again rose into the air, and was afterward found dead in a field about a mile from the place where the balloon made its second descent. That this dreadful close of the aeronautic career of Mr. Gale, which he commenced only in 1848, will serve as a warning to this reckless class of adventurers, we hardly anticipate. That it will put a stop to such fool-hardy and hazardous exhibitions, by bringing them into disrepute with the idle multitude, is what we as little expect. So long as men are found sufficiently daring to run the risk, there will not be wanting crowds abundantly ready to pay down their money, and gaze upon the spectacle with a stupid admiration.

It is a wretched result of the art of ballooning, if it can be turned to no better account than this. Can, then, nothing more important be brought out of it? Can it never be rendered subservient to the ordinary purposes of human life? The opinion almost universally prevalent among men, not excluding scientific men, is that it can not. Some aeronauts, indeed, assure us that the time is fast approaching when aerial transition will inevitably be placed as far before railroad and steam-boat transition as the latter are before the old-fashioned sail and horse-power modes. But the most of men place little faith in these flattering anticipations; they listen to or read them with as dogged a skepticism as they read or hear the celebrated vaticination of Bishop Wilkins, that it would be as common for man hereafter to call for his wings when about to make a journey, as it then was to call for his boots and spurs. They doubt whether, with all the characteristic marks of progress that distinguish the present age, balloons will ever become a safe, cheap, and expeditious means of traveling. Whether the aeronauts are most to be justified in their sanguine expectations, or the rest of mankind in their cautious incredulity, time alone will determine. Our judgment, we confess, strongly inclines to the side of the skeptics.

Much is still desiderated, in order to the practicability of ballooning as a generally useful art. A new gas, at once cheap in its production, and of sufficient buoyancy, must be discovered. The gases at present employed for inflating balloons are either too expensive or too heavy. Hydrogen, which is almost fourteen times lighter than common air, is the lightest gas known, but the expense at which it is procured is an insuperable objection to its practical utility. To produce a quantity sufficient to raise the weight of a pound, four and a half pounds of iron or six of zinc, with equal quantities of sulphuric acid, would be required. Carbureted hydrogen or coal gas is much cheaper, and brings the cost of what may be necessary for experimental purposes – though this is by no means inconsiderable – within the compass of more ordinary means. But, as it is only about one half lighter than atmospheric air, it would require a machine of immense size to support any great weight; and the whole experience of ballooning proves the difficulty of managing a body of great magnitude. Another great desideratum in aerial navigation is a power of guiding the balloon according to a given direction – of propelling it through the atmosphere as steam-boats are propelled on the ocean. It has indeed been said that, as nature is very profuse in the variety of atmospherical currents within two miles above the level of the sea, we are not, in sailing through the air, driven to the necessity of attempting to go right against the wind, but have only to ascend or descend, as the case may be, to a current, which will waft the vessel to its desired destination. But were we even sure of always getting a favoring current, which, from the limited amount of observations made, is not yet established beyond a doubt, there is another desideratum – we are in want of an agent adapted for raising and lowering the balloon without any waste of its power, so as to get within the propitious current. Mr. Green's contrivance of the guide rope, is, as we have seen, not likely to answer in practice; and nothing better has yet been discovered.

"Bridge of sighs:" – Two men of memorable genius, Hood last, and Lord Byron by many years previously, have so appropriated this phrase, and re-issued it as English currency, that many readers suppose it to be theirs. But the genealogies of fine expressions should be more carefully preserved. The expression belongs originally to Venice. This jus postliminii becomes of real importance in a case like that of Shakspeare. It is a most remarkable fact that he is made to seem a robber of the lowest order by mere dint of suffering robbery. Purely through their own jewelly splendor, have many hundreds of his phrases forced themselves into usage so general, under the vulgar infirmity of seeking to strengthen weak prose by shreds of poetic quotation, that at length the majority of careless readers came to look upon these phrases as belonging to the language, and traceable to no distinct proprietor any more than proverbs: and thus, on afterward observing them in Shakspeare, they regard him in the light of one accepting alms (like so many meaner persons) from the common treasury of the universal mind, on which treasury he had himself conferred them as original donations of his own. Many expressions in the "Paradise Lost," in "Il Penseroso," and in "L'Allegro," are in the same predicament: from glorifying their author, so long as they were consciously referred to him as their author, they have, at least, ended in tarnishing his glory. As creations, they were marks of power; as tributes levied upon a common stock, they become arguments of weakness.

Since those years, it is natural that mere culture of the subject, and long, experience in the arts of composition, should have sharpened my vision, previously too morbidly acute, to defects in the construction of sentences, and generally in the management of language. The result is this: and perhaps it will shock the reader, certainly it will startle him, when I declare solemnly my conviction, that no two consecutive pages can be cited from any one of the very best English authors, which is not disfigured by some gross equivocation or imperfection of structure, such as leaves the meaning open, perhaps, to be inferred from the context, but also so little expressed with verbal rigor, or with conformity to the truth of logic, or to the real purpose, that, supposing the passage to involve a legal interest, and in consequence, to come under a judicial review, it would be set aside for want of internal coherency. Not in arrogance, but under a deep sense of the incalculable injuries done to truth, small and great, by false management of language, I declare my belief that hardly one entire paragraph exists in our language which is impregnable to criticism, even as regards the one capital interest of logical limitation to the main purpose concerned.

From the naked character of the whole area on each side of the Oxford-road, at that time, there was very little opening for ambuscades. What little there was, which greatly fascinated my brother as one of the features connecting his own strategies with those of Cæsar, lay exclusively among the brick-kilns. Of these, there were numbers on the clay-fields adjacent to the road: and sometimes having been irregularly quarried (so to speak), they opened into lanes and closets, which offered facilities for momentary concealment. But the advantages almost ceased to be such from their obviousness, and the consequent jealousy with which they were watched and approached. The particular mode of my three captures was the constant mode of my danger; two or three parallel files advanced up the rising ground from the river; one or two of these by shouts, by more conspicuous activity, and by numerical superiority, succeeded in winning too exclusive an attention, while a slender thread of stragglers, noiseless, and apparently not acting in concert, suddenly converged when approaching the summit of the ascent, and instantly swept so rapidly round the left of my position, as in one moment to take away all chance of restoring the connection between myself and my brother; while, at the same time, by exposing too decisively for doubt the preconcerted plan on which they had really been moving, when most of all simulating the disarray of stragglers, they mortified us by the conviction that students of Cæsar's Commentaries might chance, notwithstanding, to show themselves most exemplary blockheads.

The most plausible reason assigned is that of the expansion of the tube toward the fire by the influence of the heat. The fallacy of this theory is at once shown by the fact that, although heat does expand bodies, it does not increase their weight; therefore, notwithstanding that one side of the tube may be expanded, its equilibrium will remain unimpaired.

This story is attested, with slight variations, by several writers, Petronius, Dion Cassius, Pliny, and Isidorus. Pliny says that the populace, imagining that their interests would be injured by the discovery, destroyed the workhouse, tools, and dwelling of the artificer.

To such an extent has this jealousy been carried, that many adroit expedients have been employed to mislead and baffle curiosity. Hence the infinite variety of receipts for the production of different sorts of glass that have been launched upon the public, a vast number of which have been got up expressly for the purpose of deceiving and misdirecting the inquirer. To this circumstance may be referred the remarkable contradictions and inconsistencies that may be detected in all treatises on the subject.
