Man has through the ages sought in vain for an imaginary elixir of life, the divine Amrita, a draught of which was thought to confer immortality. But the true elixir of life lies near to our hands. For it is the commonest of all liquids, plain water! I remember one day standing on the line which separates the Libyan Desert from the valley of the Nile in Egypt. On one side was visible a sea of billowing sand- without a speck of green or a single living thing anywhere visible on it .On the other side lay one of the greenest, most fertile and densely populated areas to be found anywhere on the earth, teeming with life and vegetation. What made this wonderful difference? Why, it is the water or the river Nile, flowing down to the Mediterranean from its sources a couple of thousands of miles away. Geologists tell us that the entire soil of the Nile valley is the creation of the river itself, brought down as the fine silt in its flood waters, from the highlands of Abyssinia and from remote Central Africa and laid down through the ages in the trough through which the Nile Flows into the sea. Egypt, in fact was made by its river. Its ancient civilization was created and is sustained by the life-giving waters which come down year after year-with unfailing regularity.
