Thunder and Lightning
John Stuart Mill · en
Much frightened, the young woman tried to escape; she threw herself
towards the door and opened it, when the fireball at once followed
her, played about her feet, went into the next room, which opened
out-of-doors, crossed it, and through the door into the yard.
It went round the yard, entered a barn by an open door, climbed the
wall opposite, and reaching the edge of the roof, burst with such a
terrific noise that the peasant woman fainted. The barn at once took
fire and was reduced to cinders.
Towards the middle of the last century, March 3, 1835, the steeple of
Crailsheim was set on fire by lightning. The guardian's daughter, aged
twenty years, was at this moment in her room and had her back turned
to the window, when her young brother saw a fireball enter by the
window-sill and descend on to his sister's back, giving her a sudden
shock all over her body. The young girl then saw at her feet a
quantity of small flames, which went towards the kitchen, the door of
which had been opened, and set fire to a pile of mossy wood. There was
no further damage than this attempt at incendiarism, which was easily
extinguished.
Occasionally a fireball seems to take a malignant pleasure in hurling
itself like a fury against lightning conductors; but instead of
quietly impaling itself like the linear lightning, and breathing its
last sigh in a prolonged roar, it struggles, and comes forth
victorious from this curious contest.
There are many cases of fireballs playing about the lightning
conductors without being caught.
In 1777, a fireball shot from the clouds on to the point of the
lightning conductor on the Observatory of Padua. The conductor, which
consisted of an iron chain, was broken at its junction with the stem.
However, it sent on the discharge.
Some years later, in 1792, a huge ball of lightning struck one of the
two conductors on the house of M. Haller at Villiers la Garenne. This
conductor was much injured by the audacious assailant, and so was the
framework of the house; the keen fluid had damaged the metallic
gutters.
At this point I must add that lightning conductors are of recent
creation. Nor would it be surprising if there were defective ones
which could not assure an efficient protection.
However, much later, on December 20, 1845, the same phenomenon was
observed at the château of Bortyvon, near Vire. There, again, the
fireball, ignoring the danger to which it was exposing itself, flung
itself on a lightning conductor placed in the centre of the château.
It was spared, but the château suffered greatly. The electric ball
descended from both sides of the metallic stem, causing a great deal
of damage along its path. On touching the ground it expanded, and many
persons affirm that they saw what was like a huge cask of fire rolling
along the ground.
In truth, ball lightning seems in a certain measure to escape the
influence of lightning conductors.
