Thunder and Lightning
John Stuart Mill · en
On May 17, 1852, towards five o'clock, the sky looking overcast, the
station-master at Havre warned his colleague at Beuzeville that it
would be well to put his apparatus in connection with the ground.
Beuzeville is twenty-five kilometres away from Havre, and at the
former station the weather then did not look at all threatening. But
clouds soon piled up, driven before a violent wind. Suddenly three
awful peals of thunder succeeded each other in quick succession. With
the last, lightning struck a farm about a kilometre from the station,
and at the same moment a globe of fire of a reddish brown, and
apparently about the size of a small bomb-shell, rose as if out of a
clump of trees. It glided through the air like an aerolite, and
leaving behind it a train of light. At a hundred metres or so from the
station, it alighted like a bird on the telegraph wires, then
disappeared with the rapidity of lightning, leaving no trace of its
passage, either on the wires or the station. But at Beuzeville several
interesting phenomena were observed. Firstly, the needles turned
rapidly, with a grating noise like that of a turnspit suddenly running
down, or like a grindstone sharpening iron, which emits sparks. A
great number, indeed, flew out of the apparatus. One of the needles,
that on the Rouen side, went out of order; all the screws on that part
of the instrument were unscrewed, and on the copper dial near the axis
of the needle, there was a hole through which one could pass a grain
of corn.
The instruments at Havre were unaffected. The needle remained as
usual, also the dial, screws, and so on.
One of our correspondents has sent me the following very interesting
communication:--
"On June 26, 1901, having rung up at the central telephone-office at
St. Pierre, Martinique, a harsh noise was heard, which was almost
immediately succeeded by the appearance of a ball of fire, having an
apparent diameter of twenty centimetres, and the brilliancy of an
electric light of twenty candle power. This voluminous globe followed
the telephone wire towards the instrument. Arrived near the receiver,
it burst with a terrific explosion. The witness of this phenomenon
felt a severe shock, and dizziness. Recovered from his stupefaction,
he noted the following facts: the telephone apparatus was completely
burnt, the relay of Morse's installation was slightly damaged. The
electrical tension must have been enormous, for the wire of the
bobbins was, to a great extent, melted."
This latter effect, however, occurs very frequently. Not only does the
lightning melt and break the telegraph wires, but it injures the poles
which support them.
