nd greater power would be infused
into the revolving cone as it moved forward. When passing over a
smooth, level plateau, it would excite less of the electrical fluid,
and would hence be disarmed of a portion of its ability to destroy
buildings and fences.

The second important point that we must consider is the increased
destruction of property and great violence exhibited on the right side
of the centre of the revolving axis of the storm-cloud, and a
corresponding diminution of destructive power on the left side. The
movement of the whirl was undoubtedly from right to left; the fallen
trees indicate it. The forward motion of the hurricane would create a
great inrushing of wind on the right side, and greater damage would
result than upon the other side where the wind was returning to
complete the rotary movement. While it is true the trees were
overthrown to some extent in all directions, yet they mostly fell in
the direction in which the wind struck them as it moved around in its
whirling motion. The southern side of the track of desolation,
however, presents evidence of the greatest power. The maple and other
forest trees were frequently twisted entirely off, showing
conclusively, that while they were first struck by the progressive
motion, the rotary motion was sufficiently quick to locate the falling
trunk. The great power of the storm-cloud was due to its revolution.
In fact, this marks the difference between the high wind and the
hurricane or tornado. The phenomena observed in connection with the
storm of July first, are almost identical with those of similar
character in the Southern States and West Indies.

The third subject presented for our consideration is the upward and
downward currents which seemed to exist within the cloud. Objects were
thrown upward to an immense distance, and the distance to which some
objects were driven into the earth must convince us that there was a
force downward of great power. It is true that a falling body, when
influenced by gravity alone, will descend with great force, especially
if started from a high point, but the deep excavations found in the
track of the storm can only be accounted for by a downward current.
The funnel-shaped cloud enlarging its circumference towards the top,
would, with its centrifugal force resulting from its revolution, hurl
bodies to a great distance, and we find the _debris_ of this tornado
hundreds of yards outside of its track, proving that when
