to the fish-fauna of this lake presenting similarities to marine 

 forms, the idea was current that Tanganyika represented 

 an old Jurassic sea. This theory was expounded by Mr. 

 J. E. S. Moore (known to many old Africans as Jelly-fish 

 Moore, on account of his connection with the collecting of 

 the Tanganyika jelly-fish) — in his books " The Tanganyika 

 Problem " and " To the Mountains of the Moon " ; it has, 

 however, since been found to be wrong. The large number 

 of endemic genera of fish-fauna to be found in this lake 

 compared to other lakes, is due to its undisturbed and 

 isolated position, and in no way to its supposed connec- 

 tion with the sea. 



One of the wonders of this lake and probably the least 

 known or heard about, owing to its inaccessible position 

 at the south end, is the Kalambo Falls. The Kalambo 

 River, which before the Great War formed part of the 

 boundary between Northern Rhodesia and German East 

 Africa, is a broad and swift mountain torrent for the most 

 part, which hurls itself practically from one of the lower 

 ledges of the Nyassa-Tanganyika plateau, in one drop over 

 a vast cliff, into the great gulf of Tanganyika. The fall is 

 said to be the second highest in the world and is calculated 

 to be seventeen hundred feet high. Owing to a sharp curve 

 in the cliff face, little can be seen of the stupendous fall from 

 above. To obtain a good view it is necessary to make a 

 detour round the cliff, climb down some distance, and then 

 to approach the fall from below. This I accomplished, and 

 moreover reached the foot of the fall, where I obtained some 

 very fine photographs and exposed a hundred feet of cine- 

 matograph film. 



The foot of the falls is a paradise for the naturalist and
