has held its own against such mere modern devices as gunpowder and rifle balls; and none of the objects commonly shown as thunderbolts are ever round: they are distinguished, whatever their origin, by the common peculiarity that they more or less closely resemble a dart or arrowhead.

Let us begin, then, by clearly disembarrassing our minds of any lingering belief in the existence of thunderbolts. There are absolutely no such things known to science. The two real phenomena that underlie the fable are simply thunder and lightning. A thunderstorm is merely a series of electrical discharges between one cloud and another, or between clouds and the earth; and these discharges manifest themselves to our senses under two forms--to the eye as lightning, to the ear as thunder. All that passes in each case is a huge spark--a commotion, not a material object. It is in principle just like the spark from an electrical machine; but while the most powerful machine of human construction will only send a spark for three feet, the enormous electrical apparatus provided for us by nature will send one for four, five, or even ten miles. Though lightning when it touches the earth always seems to us to come from the clouds to the ground, it is by no means certain that the real course may not at least occasionally be in the opposite direction. All we know is that sometimes there is an instantaneous discharge between one cloud and another, and sometimes an instantaneous discharge between a cloud and the earth.

But this idea of a mere passage of highly concentrated energy from one point to another was far too abstract, of course, for primitive man, and is far too abstract even now for nine out of ten of our fellow-creatures. Those who don't still believe in the bodily thunderbolt, a fearsome aërial weapon which buries itself deep in the bosom of the earth, look upon lightning as at least an embodiment of the electric fluid, a long spout or line of molten fire, which is usually conceived of as striking the ground and
