have been destroyed, thousands of lives lost, and untold suffering
caused by the periodic recurrence of floods in certain sections of
the country, as in the lower Mississippi Valley, or as in Ohio, a
few years ago. The individual farmer has some responsibility for
such floods, because by looking after his own drainage and
preserving his own timberland he may help decrease the amount of
water that flows into the streams and ultimately causes such havoc

governments cannot alone control the floods, because the waters
that cause damage in Louisiana and Mississippi come from the
states along the entire course of the Mississippi River and its
