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.
