t incessantly, while
the thunder roared until it seemed as if the very earth was shaken.

Even George had never passed a summer in this section of the country
before, and he knew no more than did Ralph the destruction often caused
by the electric current where so much inflammable material is stored.

Without a thought of the possible catastrophe that might occur, they
remained under their apology for a shelter, through which the water
poured in anything but tiny streams, looking out at the majestic
spectacle, fearing only that the wind might throw the frail shed down
upon them.

"Look there!" cried Ralph, as an unusually brilliant flash was seen. "It
almost appeared as if the lightning ran entirely around that oil-tank.
I wonder if those are ever struck?"

"It must make sad work if they are," replied George, thinking for the
first time of such a possibility. "In that tank alone there must be
fully thirty-five thousand barrels of oil, and the conflagration would
be something terrible."

He had hardly ceased speaking, when there came a flash that almost
blinded them as it descended directly on the top of a huge derrick,
crackling and hissing as it came, and in what seemed to be the slightest
possible fraction of time, the air was filled with fragments of the
heavy timbers, while, despite the pouring rain, a sulphurous odor was
perceptible.

The derrick had been struck, and its thousand fragments strewed the
earth in every direction.

"How terrible!" cried Ralph, as he covered his face with is hands in
affright, for never before had he witnessed the terrific force of the
lightning's bolt.

George stood at the door of the shed, restless, regardless alike of the
deluge of water that fell upon him, and of the neighing and stamping of
the frightened horses; he was like one fascinated by the awful majesty
of that which he saw everywhere around him.

His gaze was directed toward the largest oil tank in the valley, while
it seemed as if some will stronger than his own impelled him to look at
this enormous construction of iron, filled with its easily ignited
contents; and as he thus stood, awed into silence, it seemed to him that
the largest cloud was rent entirely asunder, while from its very center
a torrent of fire was poured on to the tank, from which the flames
appeared to leap to meet the shaft from heaven.

In an instant the entire body of oil was a seething mass of flames,
while the very rain seemed to add to
