• The rain is plentious but, by God's decree,
    Only a third is meant for you and me;
    Two-thirds are taken by the growing things
    Or vanish Heavenward on vapour's wings:
    Nor does it mathematically fall
    With social equity on one and all.
    The population's habit is to grow
    In every region where the water's low:
    Nature is blamed for failings that are Man's,
    And well-run rivers have to change their plans.
