XXXV.] LAKE SYSTEM. 459 



The Albert is parallel to the curve the coast mountains take 

 to the eastward of north in running out to form the highland 

 extending up to Cape Guardafui, and of which Socotra Abd- 

 al-Kuri and the neighboring islets and rocks are the outlying 

 fragments. 



These three lakes, therefore, seem to lie in an interrupted 

 tissure on the outside of one in a series of concentric upheavals. 



In support of my behef that Lake ISTjassa lies at an angle to 

 the meridian like the Tanganyika, 1 am inclined to refer the 

 reader to Mr. Cooley's " Geography of the Nyassa,'" a paper in 

 which, notwithstanding the disadvantages of having to work 

 with defective and, in many cases, erroneous data, the scientific 

 writer made an immense advance toward breaking through the 

 darkness which for so long had shrouded the interior of Africa. 



Lake Victoria Nyanza owes its existence to some other cause, 

 while of the many lakes to the westward of this line some are 

 apparently formed by rivers dammed back by ranges of hills at 

 the edges of table-lands, wdiile others are simply lacustrine ex- 

 pansions of varying size of the rivers tliemselves. 



The name of Tanganyika means " the mixing-place," being 

 derived from ku-tanganya — in some dialects changanya — "to 

 mix or slmfiie." 



The fact that I found no fewer than ninety-six rivers, besides 

 torrents and springs; flowing into the portion of the lake which 

 I surveyed, proves this name to be well deserved. 



Behind Kawele towered lofty hills, which could be seen long 

 after the low land on which the town was built had disappeared 

 below the horizon. 



Proceeding southward from Kawele, the shore of the lake at 

 first consisted of dwarf cliffs of red sandstone, broken by land- 

 slips and fringed at their base by matele, or cane grass, while 

 l)ehind were wooded hills rising higher and higher as they re- 

 ceded from the lake. 



A level marshy plain extends at the mouth of the Ruche, 

 whence the coast rises gradually until it culminates in the 

 double promontory of Kabogo. This section is broken into 

 deep inlets and bays by the mouths of the Malagarazi and other 

 rivers ; the Malagarazi running into the lake by the side of a 

 long red quoin which can be seen from LTjiji, The cape at
