 soil, or by those falls of the ground, which vio- 

 lent earthquakes occasion. It is probable, that 

 in the lapse of ages, several rivers of Soudan, 

 and of New Holland, which are now lost in the 

 sands, or in inland basins, will open themselves 

 a way toward the shores of the ocean. We 

 cannot at least doubt, that in both continents 

 there are systems of interior rivers, which may 

 be considered as not entirely developed* ; and 

 which communicate with each other, either in 

 the time of great risings, or by permanent bi- 

 furcations. 



The Rio Pao has scooped itself out a bed so 

 deep and broad, that in the season of rains, 

 when the Cam grande de Cambury inundates 

 all the land to the North-West of Guigue, the

 maps an imaginary chain of mountains, between
