Communications wade by a Native respecting a Lake in the 



Interior of South Africa. 

 The lad named Moopi, from whom the following notices were pro- 

 cured, visited Cape Town in 1834, in the service ot" the Rev. — Wright, 

 Missionary at Griqua Town. His age appeared to be about 20. He 

 could converse only in the Sichuana language, and communic.ition was 

 carried on with him by means of a Bichuana youth, who could speak 

 Dutch. Conversations" were held with Moopi on two occasions, both 

 the Secretaries of the S. A. L. & S. Institution being present at the 

 first of them, but only one of them at the other. Mr. Wright was 

 present on both occasions, to interpret from the Dutch language into 

 English. It would scarcely be deemed proper to present to the public, 

 information gained through a channel so circuituous, and wherein there 

 are so many chances of mistake, if it were not that the whole communi- 

 cation wears decidedly the aspect of probability, as agreeing with what 

 we know of the adjoining countries, and with what has been gleaned 

 from other sources respecting that to which it refers, and such as it is, 

 the notice may serve to keep alive the interest of the public in a district 

 which seems abundantly deserving of its notice. Several writers have 

 given scanty reports of the existence of a Lake conceived to be to the 

 northward 'of the Southern Tropic, and near the meridian of Cape 

 L'Agullas. The following communication refers especially to that Lake. 

 In the second examination of Moopi nothing was discovered which 

 varied from his former accounts in regard to the subjects common to 

 them both, except as to the name of a town situate near to the Lake, and 

 of the Chief then ruling it. It must he understood, in general, that the 

 information can be received as precise or of value only in proportion as 

 it refers more or less to those objects to which the attention of men in a 

 state of barbarism is powerfully directed. In regard to the sound'; of 

 the names, it is to be observed, that the letter ^>- when preceding // or 

 following 71 has an aspirated gutteral sound not found in English. 



Moopi s communications were to (Ills eH'ecl : — He belongs to llie IJaqiipen

 Chief named Sihoutiani, drove them (roni I his place, and they fled to Lihoo-

 for twelve months, from place to place, not in a direct line, but traversing 

 from side to side as grass and water were to be found, until they settled in a 

 country near a great water. In this journey they ;nel with no rivers, but found 

 water only in ponds, and the rains were in autumn,— the country is very llai. 



They went to a town named Umpooroo. The Chiefs name was Towan. The 

 great water is about two days journey westward of tlie town. There are 

 towns and cattle posts upon its banks. Close to the town and eastward of it, 

 are mountains wliicli seemed as high as (lie Table mouiitilin of Ibc Cape. Me
