CHAPTER VII.
OTHER TORNADOES.
Оглавление“From the dark earth impervious vapors rise,
Increase the darkness and involve the skies.
At once the rushing winds, with roaring sound,
Burst from th’ Æolian caves and rend the ground;
With equal rage their airy quarrel try,
And win by turns the kingdom of the sky.
But with a thicker night black Auster shrouds
The heavens, and drives on heaps the rolling clouds,
From whose dark womb a rattling tempest pours,
Which the cold north congeals to haily showers.
From pole to pole the thunder roars aloud,
And broken lightnings flash from every cloud.
Now smokes with showers the misty mountain ground,
And floated fields lie undistinguished ’round.
Where late was dust, now rapid torrents play—
Rush through the mounds, and bear the dams away.
Old limbs of trees, from crackling forests torn,
Are whirled in air, and on the winds are borne.”
casual glance at the papers during the last days of March would have satisfied any one that the storm which passed over the country was anything but insignificant. So far, we have given only the story of a single neighborhood; while a score of others suffered more or less. A brief account of some of these will be of interest, and will give us a far better idea of the character of great storms and tornadoes.
The farthest point west touched by a tornado on that memorable day was a strip near the line between Missouri and Kansas, some fifty or sixty miles south of Kansas City. Here, a small tornado made its appearance about five o’clock in the afternoon, demolishing some fences and

barns, and breaking down a few trees: but, so far as known, no one was hurt. Meanwhile, the main storm had passed eastward much earlier in the afternoon.
Shortly after the storm reached St. Louis, violent cyclonic movements were excited in southeast Missouri, upwards of a hundred miles away. At 3 P.M. the little town of Bloomsdale was struck, and five houses were instantly prostrated. The occupants of four of them were, at the time, in the Catholic church, and the family who occupied the fifth escaped unhurt. Two sides of their house were blown away; while one side was blown inward, and would have crushed them but for chairs and tables which sustained its weight. The church suffered the loss of its steeple, and was otherwise damaged. A stable containing seven horses was blown away, and not one of the horses was injured.
A cloud gathered, and a cyclone seemed to form at, or over, Charleston. It followed the Cairo branch of the Iron Mountain Road eastward. Four miles from Charleston it struck the flag-station known as Hough’s, having on the way demolished one or two farm-houses, and made havoc of the forest. The little hamlet of Hough’s was razed from the earth, not a house being left intact. One dwelling was blown two hundred feet across the railway track and smashed. The owner, his wife and son were killed, and another son was badly injured. The three-year-old baby was taken up unharmed. Another family lived near by in a log house. It was blown away, and they were left sitting on the floor, wondering.
Such a case as this is by no means rare. It is one of the many freaks of the wind not easily understood. In the great cyclone of forty or fifty miles in diameter, the wind comes in gusts or waves, and such effects might be readily understood; but in the case of the tornado, of at most but a few Hundred yards in diameter, its passage is too rapid for those in its path to learn definitely whether it be uniform or not.
Other peculiar feats were noticed at Hough’s. A girl seventeen years old was blown one hundred and fifty yards into a pond, but was rescued in time to save her from drowning; and it is said that a man and woman were blown across a sixty-acre wheat field, and picked up insensible. The further statement that the bark was peeled clean from the trees, though seemingly most incredible of all, is very probably true; for the writer has a vivid recollection of precisely the same phenomenon on the theater of the Marshfield cyclone in southwest Missouri. In that instance the bark was peeled from hundreds of hickory saplings, almost from the roots to their topmost twigs. This effect was inconceivable from any cause that could be thought of. It was done by missiles flying through the air, or the trees were bent over and threshed against the ground, or there was some unknown force prevalent in the storm, similar, perhaps, to that which shatters the bark or body of a thunder-smitten oak. To an observer on the ground the first two suppositions seemed to be excluded. Is this peculiar power of the tornado to be sought, like that of Keely’s Motor, in some occult force?
From Hough’s Station the tornado may have bounded above the tree-tops and descended again a few miles further on at Bird’s Point, opposite to Cairo, Illinois. Anyhow, a tornado struck the former place at 4:35 P.M. It was first seen above the trees, it showed a yellowish cast, and had the usual funnel shape. About three hundred yards from the town it came to the ground and commenced its work of destruction. Eight or ten houses were blown to pieces, or badly damaged; a roof was carried two hundred feet into the air; a yearling calf was thrown forty

feet into a big ditch filled with, water, and—nobody was hurt.
At Cape Girardeau, on the Mississippi, fifty miles above Bird’s Point, there was a tremendous hail, which broke thousands of windows, and a gale lasting far into the night, with damage to timber, fences, and buildings.
Illinois suffered far worse than Missouri. The southern part of the state fared badly; and the further south, the worse. The storm which struck St. Louis at 3 P.M., was, a few minutes later, giving the Illinois towns on the other side a lively experience. Edwardsville, O’Fallon and Centerville received a heavy gale. At Coulterville, buildings, barns, and orchards suffered severely, and several persons were injured. Sparta was struck about 3:15 P.M. From the second story of the public school building, observers watched the approach of the storm. Two black clouds from opposite quarters of the heavens came together, as by attraction, and mingled with a rotary motion. The tornado passed within a mile of the town on the northeast, and mowed a swath through the heavy timber. No such rain, hail and wind, mingled with fire, had ever been seen before. Many barns were destroyed; several houses were blown to pieces; three or four persons were seriously hurt. A traveling man was whisked out of his buggy by the wind, carried some distance, and sustained severe injuries; the horses were thrown down, and the buggy was completely wrecked.
At Grand Tower, on the Mississippi, forty miles above Cape Girardeau, there was a terrific tornado at 4:30 P.M. It came from the west, and swept houses, trees, trains—everything, in its course. Its track is described as one of “extreme desolation.” Four or five persons, at least, were killed, and as many injured. Twenty-seven dwelling-houses were completely demolished, and a great many others unroofed, or otherwise damaged.
At Murphysboro, Illinois, many windows were broken by the great hail; while there came an unverified report of fifteen or more persons killed about Shiloh, and to the north of Campbell Hill. South of Murphysboro, several houses were blown down; two children were killed.
At Centralia, two and one-fourth inches of rain fell in twenty minutes, changing later into snow. Farm buildings west of town suffered considerable damage.
At Carbondale, the dreaded funnel appeared, and two blocks of houses were unroofed.
Five miles southwest of Xenia, many out-buildings were blown down and several houses destroyed. A school-house on the prairie was blown away, and one of the sills carried nearly a quarter of a mile.
In the southern part of Union county, seven miles southwest of Anna, a tornado swept a track about half a mile wide and four miles long, over the richest farms, destroying stock, orchards, forests and houses. One or two persons were fatally hurt. At Mt. Pleasant, twelve miles east of Anna, there was extensive destruction of property.
At Braidwood, a number of houses and out-buildings were blown away; trees were torn up, several persons severely injured, and two or three children are said to have “disappeared.” The writer remembers an instance that occurred some years ago, when a fourteen-year-old boy was carried five miles and dropped into a stream: but such a case does not occur in this country once in many years. One of the freaks told of the wind at Braidwood is, that it rolled a man in the road and whisked a watch out of his pocket. It does not appear that any funnel-shaped cloud was seen here.
At Cairo, out of a fleet of shanty-boats, thirteen were destroyed, and an old cripple was drowned.
The storm struck Nashville (Ill.) at 4 P.M. The rain,
RUINED DWELLINGS.
changing to furious hail, fell so fast that one could scarcely see ten feet. The wind blew with terrific force. The Prohibition Tabernacle and a two-story brick cooper shop went down. Beginning six miles southeast on Little Prairie, the damage was fearful, and ranged through a sweep, to the northeast, of twenty miles. Not less than thirty houses were destroyed, and twice that number badly damaged. Of numerous casualties, one or two will illustrate the force of the wind at this place: One family of seven were sitting in their house as the storm drew near. Two of the little girls becoming frightened, ran out, when the wind caught them up, carried them across a field a quarter of a mile wide, and dropped them uninjured, save from violent pelting of the hail. As the remaining members of the family were in the act of forsaking the house, it fell, and all were more or less hurt.
This case would seem to indicate a lack of uniformity in the strength of the wind; it being powerful enough at one point to carry away children, while the house, only a few feet away at most, was still standing. One or two other cases of persons being carried a considerable distance were reported from Nashville.
All such instances show the powerful upward current of the tornado; for wind of greater horizontal velocity is often observed, which produces no such effects. To the uplifting force must be in some degree attributed the fact that in many cases only roofs or upper stories are damaged. This same force is responsible for not a few showers of objects that do not pertain to the upper air: such as the occasionally reported showers of fish and frogs.
A tornado swept up Bay Bottom in Pope county, accompanied by “rain and hail in floods and volleys.” A partial report shows a school-house dashed against a bluff a hundred feet away and reduced to kindling-wood. A number of residences were destroyed, and several persons were killed.
In all the cases hitherto noted, the tornado, when seen, is reported as about one-eighth of a mile wide. The next one on the list, while powerful, is much smaller.
The southwest part of Olney was devastated by a cyclone at 5:35 P.M. Its track was about a hundred yards wide and a mile long. It shattered or destroyed the homes of, perhaps, five hundred people. Strange to relate, only two or three persons were badly hurt. John Bourrell was voted the wisest man. His house was blown to atoms; but he and his wife were safe in their “cyclone cellar,” and absorbing much comfort from a $600 cyclone policy on their building.
But the climax of ruin for Illinois was reached at Metropolis, a town of 4,000 people, situated on the Ohio River, thirty-eight miles above Cairo, and eleven miles below Paducah. A greenish tinge of the approaching cloud was the only unusual portent. “Suddenly there came from the southwest a rolling, apparently born of the union of two clouds, which met in mid-air, and in a moment swooped down into the Ohio river, now at flood-tide, and on lifting, there followed it a column of water, estimated all the way from fifty to two hundred feet in height.” This curious phenomenon swept onward, striking the river front like the hammer of a Cyclop. In an instant, down went a large number of buildings, including principal business houses, and the finest residences of the city. A few persons were seriously hurt, and two or three were killed. Of course, there were wonderful escapes. One gentleman had a numerous array of little children; the house was swept from over the family, and not a soul was hurt. In the country the devastation was even more appalling. Residences, out-buildings, churches, even grave-stones were wiped from the face of the earth.
A relief committee was organized. In their dispatch of two days later, addressed to the St. Louis Republic newspaper, and praying for help, they say: “Hundreds of homes, the result of a life of labor, have been swept away in less time than it takes to record it. All kinds of property have been destroyed. The damage is estimated at over $200,000.”
PATH OF TORNADO—OLNEY, ILL.
Such is a partial list of the more important casualties of the great storm. Space is lacking to give detail to all the minor visitations and incidents. Such storms only attract the attention of the public when some thickly-settled region is visited. Numerous hamlets and small towns might be named, of which nothing but the bare fact that a tornado passed through is recorded. The rural districts are, of course, far more frequently swept; but the narrowness and short path of the tornado preclude its doing much damage among them.
Now, we have noticed a dozen different localities, all experiencing much the same sort of storms. The unthinking person might deem all this devastation the work of a single storm. Such is the case: but a distinction must be made between the storm itself, and the tornadoes produced by it. That there were various tornadoes entirely distinct, or independent of each other, the reader may clearly perceive, by examining the foregoing pages. It will be noticed that in several cases the tornado was seen to form near the spot devastated; and further may be noted the hours at which the whirlwinds appeared. For instance, the one which passed near Shawneetown, Missouri, came later than most of those in Illinois; yet all moved toward the northeast. A brief review of the main storm will be of interest, and show how the various tornadoes were produced.
It has already been stated that the storm originated somewhere about the southwest corner of Wyoming. Here, as early as Wednesday morning, the Signal Service observed an area of very low barometer. It moved rapidly eastward, with a trend toward the south, passing in the vicinity of Denver, Kansas City, and St. Louis, thence northeast through the central part of Indiana to Lake Erie. The central path of the storm was a violent and progressive movement of the air, doing in its passage trifling damage in some localities. The cyclonic movements which did the principal mischief, were all to the south of the storm center, and were local and violent motions of the air about an axis, while yet there was a progressive movement from southwest to northeast.
Now, these lesser whirlwinds are produced in exactly the same way as the great cyclones of many miles in diameter, which we have already seen do not originate on land often, because of the irregularities of surface that hinder. But the local currents of wind, in meeting, produce the whirling motion. Compare with the moving of a current of water. Every river forms eddies along the bank, which move a short distance down and toward the main current, and then break up. Consider the great area of low barometer moving eastward, and it will be seen that the local tornadoes, suddenly forming and moving but a few miles, are simply eddies on its edge. It is easy to watch these produced on a small scale; for nature’s principles are the same in small and great: when we have mastered the atom, we have mastered the whole object.
SCENE AT OLNEY, ILL.
Let one observe a great fire in a forest or prairie. On the outskirts of newly burned areas, when the air has been rarefied by heat, may be seen sudden and violent movements about a point, as though there was a spirit in the wind. In a moment it has lifted the ashes and scorched

stalks, and whatever light matters were in its way, and circling, perhaps, wider and stronger for a time, has borne them onward and upward toward the heavens, where at length its force was dissipated, and it mingled with the surrounding air. Similar movements were excited along the southern limits of the storm area, which we are describing; and hence, not one cyclone, but more properly speaking, a multitude of little cyclones—tornadoes independent of each other, but dependent on the main current, or great eastward traveling storm center—swept through points in Illinois, Missouri, Tennessee and Kentucky; all rushing toward the line of the lowest barometrical depression, the actual and advancing storm center. Not since the Signal Service had been established had the barometer at St. Louis stood so low as 28.46, which, reduced to sea-level, means 29.08. Toward this region of rarefied air—this partial vacuum—the cyclonic movements from the south rushed with inconceivable fury, and as the nucleus of the storm was rapidly moving eastward, the cyclonic movements were turned from a north to a northeast course. All these varied movements simply result from the effort of a disturbed atmosphere to restore an equilibrium.
The illustration of the fire used above also affords a good example of the way rotation may result from rising air. Any one who has watched a great fire in calm weather knows that sparks and smoke do not rise straight up, but in spirals and whirls, the warmer centers rising faster, just as the middle of a stream flows faster than the edge.
But the powerful winds and the damage done were not all the work of the marginal whirlwinds. A storm center moving so rapidly must necessarily have carried a steady high wind. Leaving Wyoming, by Wednesday evening the storm was in the middle of Colorado; on Wednesday night, it moved well into Kansas; on Thursday, it crossed States of Missouri and Illinois, and Thursday night it was passing over Indiana.
The climax of energy was apparently not attained until the storm reached Illinois. In Missouri, more or less damage was done to fences and buildings, from Sedalia to St. Louis. At the former place, a roof or two was blown off, and the teachers in one of the schools were so alarmed that they dismissed the children. Jefferson City, sixty miles further on, made a record of damaged roofs and shattered windows. At St. Louis, there was a deluge of rain at three o’clock in the afternoon, lasting a half hour; and the wind blew with fury during the evening and greater part of the night. It drove in and smashed some plate-glass windows, blew off an occasional roof, and from the top of the corner of St. Patrick’s School, hurled to the sidewalk a stone weighing, probably, four hundred pounds.
The story of the Louisville tornado serves to well illustrate all the peculiar features of the local whirlwinds produced by great storms. They seldom travel more than thirty miles; usually much less. Sometimes as large as two miles in diameter, they seldom exceed five hundred yards; and one of but fifty yards in diameter may be powerful enough to wreck a house.
Often it is possible to trace the path of a tornado through the forest a century or more after its passage; for the reason that trees once destroyed are usually replaced by different varieties. But the tornado usually originates in the open country, though after its formation it may sweep through heavy timber.
TORNADO FOLLOWED BY RAIN STORM.
So far as loss of life is concerned, the tornado is much more to be feared than lightning. About two thousand people have been killed in this country within ten years by these rotary storms. Yet, all over the land, people put up rods that are expensive, and often worse than useless, as a precaution against lightning, when a small “cyclone cellar” could be dug that would be far more useful, and less expensive. While intense electrical displays accompany the tornado, there is no authentic record of lightning striking during one; and as will be seen in another place, the amount of electricity present seems to be rather an effect than a cause: for rapid motion of gases may be made to produce powerful electric currents.
While the tornado is justly feared in this country, yet, as a destructive agent, it is far surpassed by a number of
Instantaneous View of a Tornado.
others whose ravages are less dreaded. It would be comparatively easy to show, we think, that more persons have been killed in one way or another by railways in ten years past than by tornadoes.
The one that has been so carefully examined must not be considered as the worst our country has known. An examination of records of the past century will show a number that were more destructive to life and property. Doubtless, an account of some of these would interest the reader. Place is given to a few.
The tornado has been observed, to some extent, in this country for more than a century: but only when our central states were well peopled did it attract very great attention. It is not common in the eastern states, and but one has ever been recorded west of Dodge City, Kansas. It is not unknown in Europe, though far less common than with us, having been noticed a few times in France. In general, it is so rare that a tornado that passed through Monville in 1845 attracted such attention as to be noticed in French text-books on physics. To the American, there is nothing unusual in the conduct of this storm.
Perhaps the earliest detail of a storm of this sort among us is that of a double one in South Carolina, on the afternoon of May 2, 1761:
“The tornado crossed the Ashley River and swooped down upon the shipping at Rebellion Wharf with such fury as to threaten the destruction of the entire fleet. From the city, it was seen coming at first rapidly toward Wappo Creek, like a column of smoke, with a very irregular and tumultuous movement. The quantity of vapor which composed this column, and its prodigious velocity, produced such intense commotion that it agitated Ashley River to its depths and left the channel bare. The ebb and flow made the shipping float off to a great distance. When it struck the river, it made a noise like continuous thunder; its diameter, at that moment, was estimated at fifteen hundred feet, and its height, as seen at Charleston,
TORNADO AT MONVILLE.
at twenty-five degrees. It was met at White Point by another whirlwind, which descended Cooper River, but was not equal to the first. When they came together, the commotion in the air was much greater still; the foam and the vapor seemed to be thrown to the height of forty degrees, while the clouds that hurried from all directions toward that point seemed to rush thither and whirl about at one and the same time, with incredible velocity. The meteor then darted on the shipping in the roadstead, and reached them in three minutes, although the distance was nearly six miles. Out of forty-five vessels, five were sunk on the spot; the state ship, Dolphin, and eleven others were dismasted. The damage, estimated at more than £200,000, was done in a moment, and even the vessels that sank were swallowed up so rapidly that the people who were below had scarcely time to scramble up on deck. The whirlwind of Cooper River changed the course of the one that came from Wappo Creek, which, had it not been for that, would, proceeding in the same direction, have swept away the city of Charleston before it like so much straw.
“This terrible column was first perceived about noon, at more than fifty miles southwest of the roads. It destroyed everything in its way, making a complete avenue when it passed through the woods. The loss of the five ships was so sudden that it is not known whether it was the weight of the column of wind, or the mass of water driven upon them that made them go down.”
The tornado occasionally originates at sea and whirls up a heavy column of water for a few feet, which, meeting the dark funnel from above, presents the appearance of a pillar of water reaching the clouds. Not a few ignorant people once imagined that all rain originated from the water thus sucked up. These columns, or “water-spouts,” are generally a few feet in diameter, and may sometimes be broken by firing a cannon-ball through them. They are not ordinarily considered dangerous: but there are some exceptions, and it is not improbable that many a ship that left port, never to be heard of again, has been overwhelmed by some gigantic water-spout.
Of the most destructive tornadoes in the United States, Mississippi records the two leading ones. The first came on May 7, 1840, and Natchez was the principal sufferer, though other portions of Adams county were swept. The day began warm and cloudy, with the wind south, veering to east. At 2:15 P.M., the sky became a lurid yellow; the storm striking the river six or seven miles below the city, did not reach it until 2 P.M. The rush of the wind did not last five minutes, and the destructive blast only a few seconds. Houses were burst outward; three hundred and seventeen persons were killed in the city and on the river. Sheet tin was carried twenty miles, and windows thirty miles. One hundred and nine persons were badly injured, and property to the value of $1,260,000 destroyed. Most of the deaths resulted from drowning; two steamers and sixty flatboats were sunk, while the city was flooded with nine inches of rain. Enormous hail-stones fell. A desk fastened with three locks, was blown open by the explosive force of the expanding air within. Another curious freak of this expansive power occurred in a tornado at New Brunswick. A towel hanging on the wall was found apparently blown nearly through it. The expanding air had driven the towel in a large crevice which opened in the wall behind it; and the crevice closed as the storm passed on, holding the towel to puzzle the neighborhood.
The next great tornado visited Natchez, June 16, 1842, and killed five hundred people.
Next to these, in destruction of life, is the famous
WATER-SPOUT AT SEA.
Marshfield tornado of April, 1880, in which one hundred and one persons were killed, and six hundred injured. The town of Marshfield was literally wiped off the earth. This tornado is notable for its unusually wide path, and the large area traversed. Four counties were swept; and though the country was sparsely settled and comparatively little improved, yet the damage to property was estimated at more than $1,000,000. Gen. Greely, of the Signal Service, pronounces it one of the most remarkable in the history of the United States. It formed at the junction of two streams, a few miles southwest of Marshfield; and, like the South Carolina tornado of 1761, owed its immense power to the union of two lesser storms that had traveled down the valleys of the respective streams. Such a tornado passing over a great city would equal the earthquake in disastrous effects. Perhaps a better idea of its power may be gathered from a comparison with the New Haven storm of 1878, which killed but thirty-four people and destroyed $2,000,000 worth of property—as much as the recent storm at Louisville. The remarkable feature about every tornado—the very small destruction of life—may be better understood when it is stated that, excluding the two Natchez tornadoes, where the number of houses wrecked is not known, and the Louisville storm, the twenty most destructive tornadoes in the United States have killed six hundred and thirteen people, and destroyed over three thousand houses. This brings us to the peculiar fact that but one person is killed in every five houses. As the average house may be counted as containing four persons, it appears that the chances that any single individual in a wrecked house will not be killed, are nineteen to one. While the mathematical calculation may be encouraging, yet few will care to take the risk of a tornado, even though the odds be vastly in their favor. People place little dependence in arithmetic as a life preserver. The recent Louisville storm presents a high average, as about fifty of the victims were taken from a single building. The lowest average is shown by the tornado that struck Camden, New Jersey, August 3d, 1885, when five hundred houses were destroyed, and but six persons killed: one for every eighty-three houses. In general, there seems to be a prevalence of a one to ten rate: but a storm in a city usually vastly increases the death rate by reason of the number of brick houses, which, when wrecked, fall much more compactly than frame buildings.
MINNESOTA TORNADO, FORMING LATERAL SPURS.
The greatest destruction of property has been in Ohio, where the aggregate now amounts to about $9,000,000. Next is Minnesota with $7,000,000, and Missouri and Mississippi with about $4,000,000 each. Missouri is first in respect to loss of life, and Mississippi next. The months most liable to tornadoes are May, April, June, and July, in order; and the time of day the hottest; that is, from 3 to 5 P.M.
These data suffice to show the peculiar acts of the tornado in our land. There is one case of a great storm attended by tornadoes on its southeast border, that is even more noteworthy than the great one so minutely detailed in the preceding pages. A storm center passing over a wider region, on February 9, 1884, produced, after ten o’clock that day, over sixty tornadoes in Mississippi, Alabama, Georgia, South Carolina, Kentucky and Tennessee, and North Carolina. Over ten thousand buildings were destroyed, eight hundred people killed, and twenty-five hundred wounded. The damage done by any single one was small, while the aggregate was fearful.
The tornado is occasionally seen in Europe: but in the few instances recorded, it has been much smaller, and moved much slower than the same sort of storm in America, though quite as powerful within the territory traversed. One that was very formidable, was observed near Boulogne, in 1822. It moved about irregularly for an hour, tearing holes in the ground, snapping off trees, and twisting down houses; yet, it was not twenty-five feet in diameter. Another one in 1872, swept through a little town in Italy, and was so powerful as to twist iron balcony railings together like so many skeins of thread. Several persons were killed.
In some portions of the Sahara and of Arabia, very numerous small whirlwinds accompany desert storms, whirling up the fine sand in dense columns, presenting the appearance of clouds in a region where clouds are unknown. So many writhing columns, swaying like dancing serpents, present a peculiarly terrifying aspect to the superstitious Arab, who has only too good reason to fear them. Strange tales of their destructiveness are rife. It is said that the army of Cambyses was overwhelmed by one of these desert storms. This story must, however, be taken “with a grain of salt.” But there is no doubt that a sand storm is quite as dangerous as a Dakota blizzard.
