The World Masters by George Griffith

Eight days out of the ten calculated by the president and Doctor Lamson for the progress of the Great Experiment had expired, and Europe presented the extraordinary spectacle of a continent armed to the teeth, possessing the mightiest weapons of destruction that human science and skill could invent and construct -- and divided into two hostile camps which were practically unable to hurt each other.

Away in the far northern wilderness the giant engines purred on remorselessly, continually drawing away more and more of the vital earth-spirit from Europe and Asia. In Great Britain and North America nothing had happened, except a succession of abnormally violent thunderstorms, and certain other minor electrical disturbances which were only detected by instruments at the observatories; but all cables had ceased to work, and the only sea communication possible was by means of wooden sailing ships, for every steamer, whether warship, liner, or tramp, broke down when she got about fifteen miles from the English or American coasts. What was happening in the Southern Hemisphere no one knew till long afterwards.
