The Discovery of liuwenzori. 



of E.uwenzoi'1 was reserved neither for liiiii, noi- for Emin Pasha, 



or Mason, Ijoth of whom subsequently visited tlie lake. 



TUSKS CONFISCATED BY THE GOVERNMENT, UGANDA. 



Stanley is probablv right in attiihuting' the extraordinary 

 lack of atmospheric ti-ansparency, which renders these moun- 

 tains invisiljle even in fair weather, to vapours exhaled 

 from the surrounding plains and exposed to the heat of the 

 tropical sun. Occasionally a hreeze sweeps away these vapours. 

 At such times, as if by magic, the snow-clad ranges loom into 

 sight only to vanish again and leave the onlooker in doubt and 

 uncertainty as to the actual reality of the magnificent vision 

 vouchsafed to him. 



The discovery of this vast system of snow mountains 

 sheddine; tlieir watei's into lakes, wlience one of the greatest 

 Nile ])ranches takes its origin, finally brought to an end that 

 quest after the sources of tlie classic river whicli had played 

 so large a part in the liistory of geographical investigation.
