the very faint outline of a mountain summit, far, far away 

 on the horizon.' This passage is again suggestive. The 

 sandy and level Eastern shore of the Xyanja I i. e. water) or 

 Ukara Lake about Bahaii-ni, whence Sadi sighted, it is pro- 

 bably in E. long. (G.) 35° lo'. The easternmost, that is, the 

 nearest, point of the Earagwah, or, as Captain Speke writes 

 it, the Xarague Highlands, is in E. long. (G.) 32° 30'. 

 Thus the minimum width is 16o miles, whilst man's vision 

 under such circumstances would hardly cover a dozen. 

 Here, again, we have room for a First as well as for a Second 

 Sea. Hr Johnston suggests that the mountain- summit in 

 question might be an island rising high in the midst of the 

 Lake ; but, he adds, such a feature could not well have been 

 missed entirely by Captain Speke. Here I join issue with 

 him for reasons which can be deduced from these pages — 

 my companion and second in command never saw or heard 

 of the Ukara Lake. But it is highly improbable that 

 those who could tell Sadi the number of days required to 

 cross or to coast along the Lake would not have known 

 whether the summit was that of a mountain on terra iirma 

 or of a lacustrine islet. The latter feature is not un- 

 familiar to Mr 'Wakefield's informant : he does not fail to 

 mention (p. 324) the small conical hill in the southern 

 waters of the Baringo Lake. 



TThen Sadi declared that ' he travelled 60 days 

 (marches ?j along the shore without perceiving any signs of 

 its termination/ he evidently spoke wildly, as Africans will. 

 His assertion that the natives with whom he conversed 

 were unable to give him any information about its northern 

 or southern limit, simply means that in this part of the 

 African interior neither caravans nor individuals trust 

 themselves in strange lands, especially with the prospect
