Those terrifying outbursts which now and then cause so much destruction in our own country seem to be the concentration of the prodigious force of an immense ocean cyclone within a small space, which renders them resistless.
A writer in the _N.

Y.Herald_ gives some interesting facts regarding these scourges of the air.

While the cyclone, as we have shown, may have a diameter of hundreds of miles, the track of a tornado is often limited to a few hundred feet, and rarely has the width of half a mile.
The cyclone carries with it a velocity of as much as 100 to 140 miles an hour.

It sends a certain amount of warning ahead of its track, and the acceleration of the wind's speed at any given point, is gradual.
The tornado falls almost without notice, or rather the indications are often so similar to those of an ordinary thunderstorm that only a skilled and careful observer can detect the difference.
The phenomena and effects of cyclones in the West Indies have long been subjects of study and observation.

As the center approaches a ship she is assaulted by wind of a terrible force and a sea that is almost indescribable.
