The Victoria Nile flows out of Lake Victoria into Lake Albert, and from there into the mighty White Nile. After a series of rapids twenty miles east of Lake Albert, its colossal volume of water squeezes through a cleft in the rocks little more than twenty feet wide before dropping 400 feet in a series of three great cascades called the Murchison Falls. It is one of the most spectacular features along the Nile's 4,000-mile journey to the Mediterranean Sea.The big game hunter _cum- traveller, Sir Samuel Baker, named the Falls in 1864 after Sir Roderick Murchison, the President of the Royal Geographical Society.
