CURIOSITIES RESPECTING BURNING SPRINGS.

Naphtha Springs.—Dr. James Mounsey, and Jonas Hanway, Esq., have given a particular account of these springs. Both gentlemen, by their travels, their residence in Muscovy, and their acquaintance with several people who have been upon the spot, have had great opportunities of becoming perfectly informed of every thing relating to the subject; and whose judgment and veracity may be depended on. Both their accounts agree, that on the western coast of the Caspian Sea, not far from the city of Baku, there is a large spot of ground, where, on taking off two or three inches of the surface of the earth, and then applying a live coal, and blowing, a flame immediately issues forth, without either burning the reed or paper, provided the edges be covered with clay. This method supplies the want of candle in their houses. Three or four of these will also boil water in a pot, and they dress their victuals in this way. The flame may be blown out like that of a lamp, but otherwise it continues burning; it smells somewhat sulphureous, or rather like naphtha, but very little offensive. The ground is dry and stony, and the more stony the ground, the stronger and clearer the flame. Near this place they dig out brimstone, and here are also the naphtha springs. But the chief place for naphtha is Swieten Island, a small tract of land on the western coast of the Caspian Sea, and uninhabited, except at such seasons as they fetch naphtha from thence, which the Persians load in their wretched embarkations, without barrels or any other vessels, so that sometimes you see the sea covered with it for leagues together. The springs boil up highest in thick and heavy weather, and the naphtha sometimes takes fire on the surface, and runs lighted or burning into the sea in great quantities, and to great distances. In clear weather, it does not bubble above two or three feet. People make cisterns near the springs, into which they convey what overflows by troughs, taking off the naphtha from the surface, under which there is a mixture of water, or some other heavier fluid. The greater part is of a dark gray colour, very unpleasant to the smell, but used in lamps by the poorer sort. There are also springs of black naphtha, which is thick, and in distillation grows not clear, but yellow; but the most valuable is the white naphtha, which is naturally clear and yellowish, and bears a great price. The Russians drink it as a cordial, but it does not intoxicate: it is used externally in paralytic disorders, and is carried into India as a great rarity, where they make with it the most beautiful and lasting Japan that has ever yet been known.

What the Indians call the Everlasting Fire, lies about ten English miles north-east-by-east from the city of Baku, on dry rocky ground. There are several ancient temples, built with stone, supposed to have been all dedicated to Fire: most of them are low arched vaults, from ten to fifteen feet high. Amongst the rest, there is a temple in which the Indians now worship; near the altar, about three feet high, there is a large hollow cave, from the end of which issues a flame, in colour and gentleness, not unlike a lamp that burns with spirits. The Indians affirm that this flame has continued burning some thousands of years, and believe it will last to the end of the world; and that if it was resisted or suppressed in this place, it would rise in some other. By the number of temples, it is probable there were formerly a great number of worshippers of fire, as well Indians as Persians: they are called Gouers. At present there are about twenty persons, who reside there constantly, and go almost naked. In summer it is very hot; and in winter they dwell within doors, and keep what fire they please, in the manner above described: they live upon roots and herbs for the most part, and are supposed to attend as mediators for the sins of many who are absent; and by their applications to this fire, in which the Deity is supposed to be present and visible, they atone for the sins of others. A little way from the temple just now mentioned, near Baku, is a low cliff of a rock, in which there is a horizontal gap, two feet from the ground, between five and six long, and about three feet broad, out of which issues a constant flame, much of the colour mentioned already, being a light blue. It rises sometimes eight feet high, but is lower in still weather. They do not perceive the rock waste in the least. This also the Indians worship, and say it cannot be put out. About twenty yards on the back of this cliff is a well, and a rock twelve or fourteen fathoms deep, with exceedingly good water.

We shall next introduce an account of a Burning Spring in Kentucky.—This is a phenomenon which has for several years excited the attention of travellers, under the name of a burning spring: it exists in one of the principal forks of Licking river in Kentucky. It is situated about three-fourths of a mile from the banks of the river, and about eighty miles above its junction with Ohio, opposite Cincinnati. A spring here breaks out at the foot of a hill, forming a basin of water about six feet in diameter and two feet deep, at the bottom of which issues a stream of gas, which in volume and force is about equal to the blast forced from a common smith’s bellows; but there is no cessation of its force, which is such as to create a violent ebullition in the water. Being heavier than common atmospheric air, the gas, on passing up through the water, constantly occupies the surface, which is still the lower part of an indenture in the earth at that place. On presenting a taper, this gas instantly takes fire, and burns with great brilliancy. There is no absorption of it by the water, which possesses the purity of common spring water, neither is any offensive odour thrown off. This spring has been known to dry up entirely in the summer, when the air rushes out with increased force, accompanied by a hissing noise. There is nothing like smoke emitted.—Schoolcroft, on the Lead Mines of Missouri, p. 216.

Hot Springs of Iceland.—From Sir G. Mackenzie’s Travels in Iceland.

“The hot springs in the valley of Reikholt, or Reikiadal, though not the most magnificent, are not the least curious among the numerous phenomena of this sort that are found in Iceland. On entering the valley, we saw numerous columns of vapour ascending from different parts of it. The first springs we visited, issued from a number of apertures in a sort of platform of rock, covered by a thin coating of calcareous incrustations. From several of the apertures the water rose with great force, and was thrown two or three feet into the air. On plunging the thermometer into such of them as we could approach with safety, we found that it stood at 212°.

“A little further up the valley, there is a rock in the middle of the river, about ten feet high, twelve yards long, and six or eight feet in breadth: from the highest part of this rock a jet of boiling water proceeded with violence; dashing the water up to the height of several feet. Near the middle, and not more than two feet from the edge of the rock, there is a hole, about two feet in diameter, full of water boiling strongly. There is a third hole near the other end of the rock, in which water also boils briskly. At the time we saw these springs, there happened to be less water in the river than usual, and a bank of gravel was left dry a little higher up than the rock. From this bank a considerable quantity of boiling water issued.“About a mile further down, at the foot of the valley, is the Tungahver, an assemblage of springs the most extraordinary, perhaps, in the whole world. A rock (waoke ?) rises from the bog, about twenty feet, and is about fifty yards in length, the breadth not being considerable. This seems formerly to have been a hillock, one side of which remains covered with grass, while the other has been worn away, or perhaps destroyed at the time when the hot water burst forth. Along the face of the rock are arranged no fewer than sixteen springs, all of them boiling furiously, and some of them throwing the water to a considerable height. One of them, however, deserves particular notice. On approaching this place, we observed a high jet of water near one extremity of the rock. Suddenly this jet disappeared, and another, thicker but not so high, rose within a very short distance of it. At first we supposed that a piece of the rock had given way, and that the water had at that moment found a more convenient passage. Having left our horses, we went directly to the place where this had apparently happened; but we had scarcely reached the spot, when this new jet disappeared, and the one we had seen before was renewed. We observed that there were two irregular holes in the rock, within a yard of each other; and while from one a jet proceeded to the height of twelve or fourteen feet, the other was full of boiling water. We had scarcely made this observation, when the first jet began to subside, and the water in the other hole to rise; and as soon as the first had entirely sunk down, the other attained its greatest height, which was about five feet. In this extraordinary manner, these two jets played alternately. The smallest and highest jet continued about four minutes and a half, and the other about three minutes. We remained admiring this very remarkable phenomenon for a considerable time, during which we saw many alternations of the jets, which happened regularly at the intervals already mentioned.

“I have taken the liberty to give a name to this spring, and to call it ‘The Alternating Geyser.’

“These springs have been formerly observed, though the singularity of the alternations does not seem to have been attended to as any thing remarkable. Olafson and Paulson mention, that the jets appear and disappear successively, in the second, third, and fourth openings. We observed no cessations in any of the springs, except in the two under consideration.

“To form a theory of this regular alternation is no easy matter; and it seems to require a kind of mechanism very different from the simple apparatus usually employed by nature in ordinary intermittent or spouting springs. The prime mover in this case is evidently steam, an agent sufficiently powerful for the phenomena. The two orifices are manifestly connected; for, as the one jet sinks towards the surface, the other rises, and this in a regular and uniform manner. I observed once, that when one of the jets was sinking, and the other beginning to rise, the first rose again a little before it was quite sunk down, and then when this happened, the other ceased to make any efforts to rise, and returned to its former state, till the first again sunk, when the second rose and played as usual. This communication must be formed in such a manner, that it is never complete, but alternately interrupted, first on one side, and then on the other. To effect this without the intervention of valves, seems to be impossible; and yet it is difficult to conceive the natural formation of a set of permanent valves: so that this fountain becomes one of the greatest curiosities ever presented by nature, even though, in attempting to explain the appearances it exhibits, we take every advantage that machinery can give us. If it is occasioned by natural valves, these must be of very durable materials, in order to withstand the continual agitation and consequent attrition.”

We next proceed to a description of the Hot Springs of Ouachitta, (Washitaw.)—These springs, which have been known for many years, are situated on a stream called Hot Spring Creek, which falls into the Washitaw River, eight miles below. They lie fifty miles south of the Arkansa River, in Clark county, territory of Arkansa, (lately Missouri,) and six miles west of the road from Cadron to Mount Prairie, on Red River.

The approach to the springs lies up the valley of the creek. On the right of the valley rises the hot mountain, with the springs issuing at its foot; on the left, the cold mountain, which is little more than a confused and mighty pile of stones. The hot mountain is about 300 feet high, rising quite steep, and presenting occasionally ledges of rocks; it terminates above in a confused mass of broken rocks. The steep and otherwise sterile sides are covered with a luxuriant growth of vines. The valley between this and the cold mountain is about fifty yards wide.

The springs issue at the foot of the hot mountain, at an elevation of about ten feet above the level of the creek; they are very numerous all along the hill-side, and the water, which runs in copious streams, is quite hot; it will scald the hand, and boil an egg hard in ten minutes. Its temperature is considered that of boiling water, but Dr. Andrews, of Red River, thinks it is not above 200° Fahr. There is a solitary spring, situated seventy feet higher than the others on the side of the mountain, but it is of an equal temperature, and differs in no respect from those below. A dense fog continually hangs over the springs and upon the side of the hill, which at a distance looks like a number of furnaces in blast. To this fog, condensed into water, is attributed the rank growth of the vines on the side of the mountain.

Very little is known of the chemical nature of the water; an analysis is said to have been made, which indicated a little carbonate of lime. An abundance of beautiful green moss grows at the edges of the springs, and the paths of their waters are marked by a brighter vegetation than occurs elsewhere. The substance of the rocks here, are, limestone, slate, and quartz.—Schoolcroft, Lead Mines of Missouri, p. 258.

We shall conclude this chapter with an account of various other Burning Springs.—There are many burning springs in different parts of the world, particularly one in France, in the department of Isere, near Grenoble; another near Hermanstadt, in Transylvania; a third at Chermay, a village near Switzerland; a fourth in the canton of Friburg; and a fifth not far from the city of Cracow, in Poland. There also is, or was, a famous spring of this kind at Wigan, in Lancashire, which, upon the approach of a lighted candle, would take fire and burn like spirit of wine for a whole day. But the most remarkable one in England, or at least that of which we have the minutest description, was discovered in 1711, at Brosely, in Shropshire. The following account of this remarkable spring was given by the Rev. Mr. Mason Woodwardin, Professor at Cambridge, dated Feb. 18th. 1746:—“The well, for four or five feet deep, is six or seven feet wide; within that, is another less hole of like depth, dug in the clay, in the bottom whereof is placed a cylindric earthen vessel, of about four or five inches diameter at the mouth, having the bottom taken off, and the sides well fixed in the clay, which is rammed close about it. Within the pot is a brown water, thick and puddly, continually forced up with a violent motion beyond that of boiling water, and a rumbling hollow noise, rising or falling by fits, five or six inches; but there was no appearance of any vapour rising, which perhaps might have been visible, had not the sun shone so bright. Upon putting a candle down at the end of a stick, at about a quarter of a yard distance, it took fire, darting and flashing after a very violent manner for about half a yard high, much in the manner of spirits in a lamp, but with great agitation. It was said, that a teakettle had been made to boil in nine minutes, and that it had been left burning for forty-eight hours without any sensible diminution. It was extinguished by putting a wet mop upon it; which must be kept there for a little time, otherwise it would not go out. Upon the removal of the mop, there arises a sulphureous smoke, lasting about a minute, and yet the water is very cold to the touch.” In 1755, this well totally disappeared, by the sinking of a coal-pit in its neighbourhood. The cause of the inflammable property of such waters is with great probability supposed to be their mixture with petroleum, which is one of the most inflammable substances in nature, and has the property of burning on the surface of water.
