Rough and free in his manners, he was as full of bonhommie as good feeling. His letters are instinct with the heartiness and good fellowship of the man, and have a very agreeable freshness, and freedom from effort, if also, from any claims in the matter of thought.
In person, Chantrey did not belie his inner self. Mr. Jones, his biographer, indeed, gives us to understand, in one place, he resembled Shakspeare; in another, that it was Socrates he was like; and thereon, would have us accept a deeper similarity, of mind, to the Greek philosopher! A notion nearer the mark, is graphically supplied by his friend Thomson, when he begins his letter with a red wafer stuck on the paper; eyes, nose, mouth, &c., given in black. The symbol so pleased the sculptor, he adopted it himself as an occasional jocose signature.
Chantrey's intellect was a limited but emphatically capable, if not a very elevated one; ready at command and certain. All he said or did was, as far as it went, to the purpose. Altogether practical was the whole man. The sagacity of a sublimated common sense, was his prevailing characteristic. His mind was a perceptive one, not thoughtful or intense; making use of all that came in his way; gleaning information; receiving results, and applying them shrewdly. He attained proficiency in all he undertook, whether it were wood-carving, painting, portrait-busts, fishing, shooting. Without his range, were it but one step, he was helpless. But then, as a rule, he took care never to advance that step. And this was easy to him; for he was averse to all beyond the literal, and the every-day. The singular, the eccentric, in thought, manner of art, way of wearing one's hair, or any other department, he detested. "Let us stick to the broad, common high-way, and do our best there," was the instinctive feeling of the man. He was haunted by no unattainable, ever-retreating, fair ideals. No dreaming aspirations, or indefinite yearnings, had part in his life. His somewhat extreme, and in Mr. Jones's hands, quite over-done devotion to "simplicity," was very characteristic; in unison with that really satisfactory in him, but pointing to his wants, his restrictedness of feeling and unimaginativeness.
The same practical tendency and restriction of effort to things within reach, the sagacious, unerringly successful application of himself to the certain and definite, characterize his art: in the artist, ever the blossom and result of the whole man. Emphatic fulfillment does his success afford of the celebrated apophthegm of Mulready, "Know what you have to do, and do it." He did not spend himself on false aims, nor once lose himself in a wrong track. Having early ascertained his true field, portraiture, he consistently adhered to it, notwithstanding all "advice of friends;" though far from lacking ambition, or high ideas of the so-called higher branches. In this, his history is especially instructive, worthy of heed. He was faithful to the light that was in him. And in better times of art he might have been a still better artist.
SAILING IN THE AIR. – HISTORY OF AERONAUTICS
In the history of aeronautics, the name of Mr. Charles Green, who first turned his attention to the art in 1821, occupies a prominent place. To him the art is indebted for the introduction of carbureted-hydrogen, or coal gas, as the means of inflating balloons. Great as was the improvement effected by the substitution of hydrogen gas for rarefied air, there are serious disadvantages connected with the use of that gas. In the first place, it is procured at vast expense; and, in the second place, it is difficult to obtain it in sufficient quantity, several days of watchful anxiety having been often expended in the vain endeavor to generate a sufficiency of the gas, which, on account of the subtilty of its particles, and its strong affinity for those of the surrounding atmosphere, continued to escape almost as fast as it was produced. Perplexed at the outset with these difficulties and inconveniencies, which had not only rendered experiments comparatively rare, but even threatened the art with premature extinction, Mr. Green conceived that if coal gas, which is much cheaper and can be generated with much greater facility than hydrogen, could be employed for the purpose of inflation, an important object would be gained. To put the truth of his theory to the test, he prepared a balloon, which he inflated with coal gas, and made a successful ascent from the Green Park, on the day of the coronation of George IV. He has subsequently made some hundreds of ascensions from the metropolis, and various other parts of the empire, with balloons so inflated; and, from the year 1821, coal gas has been very generally used in experiments of this nature. Besides its economy and easy production, it has the advantage of being more easily retained than hydrogen, which, for the reasons already given, is much more readily dissipated.
The ingenuity of Mr. Green has been exerted with the view of discovering other improvements in the art of aerial navigation. One great obstacle to the successful practice in the art is, the difficulty of maintaining the power of the balloon for any length of time undiminished in its progress through the air. It is ascertained by the uniform experience of aeronauts, that, between the earth and two miles above the level of the sea, a variety of currents exist, some blowing in one direction and some in another; and when the aeronaut has risen to the elevation where he meets with a current that will waft him in the desired direction, it is of importance for him to be able to preserve that elevation. But the balloon, in consequence of the increase or diminution of weight to which it is liable from a variety of causes, will not keep at that altitude. The great changes which are constantly taking place in the weight of the atmosphere, the deposition of humidity on the surface of the balloon, and its subsequent evaporation by the rise of temperature, the alternate heating and cooling of the gaseous contents of the balloon, according as it may be exposed to the action of the solar rays or screened from them by the interposition of clouds, not to advert to other agencies, less known though not less powerful, all combine in making the machine at one time to ascend and at another to descend. Thus it may be removed out of a favorable into an adverse current. To overcome this difficulty, and enable the aeronaut to keep the balloon at the same level without expending its power, by discharging gas from the valve to lower it, or by casting out a portion of the ballast to raise it – processes which must in time waste the whole power of the largest balloon, and bring it to the earth – Mr. Green suggested the contrivance of a rope of sufficient length and material trailing on the ground beneath, and if over the sea, the rope is to be tied to a vessel filled with liquid ballast, which floats on the surface. This rope will act as a drag on the balloon, when, from any of the causes we have referred to, it tends to rise, for, in that case, it will draw up a portion of the rope, and, by thus adding to its weight, will be impeded in its upward course; and, on the other hand, when, from opposite causes, it tends to descend, it will, during every foot of its descent, have its weight, and consequently its descending tendency, diminished, by throwing on the earth the labor of supporting an additional portion of the rope. This, however, at best, is a clumsy contrivance, and there are various objections to its practical utility. It could hardly be practicable on land, on account of the damage and danger that would be occasioned by the entanglement of the rope in trees and buildings; and at great elevations above the earth, the weight of the rope would become so considerable as to require for its support a large portion of the ascending power of any balloon.
In the United States, many aerial voyages have been performed. The first of these was made by a Frenchman, M. Blanchard, in Jan., 1793, from Philadelphia, at which General Washington was a spectator. Gillio and Robertson, both Europeans, were the next after Blanchard. No Americans were engaged in the business until Mr. Durant, an ingenious citizen of New York, took it up after Robertson. He made a number of aerial excursions, and was shortly followed by new adventurers in the art, among whom the most celebrated is Mr. Wise, a piano-forte maker in Philadelphia, who in 1835 betook himself to the trade of ascending in balloons, and who up to this date has made upward of a hundred ascents.
Mr. Wise is entitled to the merit of having carefully studied and mastered the scientific principles of aeronautics, and he is among the most enthusiastic of his profession. While admitting that the art has advanced but little since its first discovery, compared with other sciences, he anticipates from it, if perseveringly cultivated by men of genius, the most splendid results, adopting, as the motto on the title-page of his work, the couplet from Shakspeare:
"There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy."
Some of his feats have
