 The direction of the primitive rock near Cape 

 Sotto is from north east to south west ; it's strata 

 incline fifty degrees to the north west f; The 

 mica-slate is silvery white, of lamellar and un- 

 dulated texture, and contains garnets. Strata 

 of quartz, the thickness of which varies from 

 three to four toises, traverse the mica-slate, as 

 we may observe in several ravines hollowed out 

 by the waters We detached with difficulty a 

 fragment of cyanite-f- from a block of splintered

 substance in South America J. 



The potteries of Maniquarez, celebrated from 

 time immemorial, form a branch of industry, 

 which is exclusively in the hands of the Indian

 stability of manners, which is the characteristic 

 of all the natives of America. Three centuries 

 have been insufficient, to introduce the potter's- 

 wheel on a coast, which is not above thirty or 



* Hours three and four of the Freiberg compass. Very 

 near the village of Maniquarez, the strata vary to hours ele- 

 ven and twelve, inclining often to the south west.

 the province of Guatimala, at Estancia Grande. Del Rio,
