When the Rodah Bridge at Cairo was practically finished as far
as the structural work itself was concerned, it was put to an
official test. The testing was minute, complex and severe in
character. Dead weights of sand and steel rails were piled up
on each pier in succession, exerting a pressure of 1,000 tons.
Subsequently live weights of steam-rollers, tramcars, loaded
with sand and water-carts filled with water were run on the
bridge while an immense pressure was brought to bear on the
bridge. If no fault or strain was visible in the material, then
it was ready for use.
Happy is the man who will cheerfully bear every burden he is called
upon to bear, knowing that he is being made ready for usefulness.
