ances in civil life following the commercial panic of 1893 was shown by the 'Coxey army of 1894' and the Chicago riots.
It is interesting to read the various causes given for financial panics and political upheavals even by historians. In 1837, the cause was said to be the State Banks. In 1857, it was the too rapid railroad expansion. In 1873, it was the reaction from the lavish expenditures attending the civil war and the contraction of the currency. In 1893, it was the low tariff and the 'free silver craze.' All of these may have been contributory causes, but if my assumption is correct that deficiency of rainfall is the paramount cause in this chain of events, then vast political and historical changes have been brought about, and the thoughts of men have been swayed by opinions which are akin to superstitions, because they attribute to human action what is due largely to natural causes beyond the control of man.
The recent period of financial distress (1893-97) in the United States was also a period of financial distress in Europe. This may have been due to the fact that Europe depends to a large extent on the United States for its food supply; or to the fact (which recent observations seem to indicate) that long periods of drought and excessive rainfall embrace a large part of the world, if not the whole world, in their operations, and are due perhaps to changes taking place in the sun.
The following extract from an American newspaper reprinted in the English periodical 'Nature,' 1895 (Vol. 53, p. 78), shows that severe droughts in other parts of the world were coincident with the one in the United States:
The existence of this drought is confirmed by recent meteorological reports from Australia. (See 'Science' of January 11, 1901, p. 75. A note concerning a simultaneous drought in Great Britain is found in 'Nature,' 1895, Vol. 53, p. 597.). These years were followed by rapid changes in political parties in Europe, especially in Great Britain and France.
