ARRIVAL AT ANGOSTURA: 985 
quake. The Boca del Infierno and the Raudal de 
Camiseta, a series of whirlpools and rapids caused 
by a chain of small rocks, were the only remarkable 
features that occurred until they reached Angostura. 
On arriving at the capital, they hastened to pre- 
sent themselves to Don Felipe de Ynciarte the go- 
vernor of Guiana, who received them in the most 
obliging manner. A painful circumstance forced 
them to remain a whole month in this place. They 
were both, a few days after their arrival, attacked

alarming state for several weeks, but retained suf-

of the stream. The houses are high, agreeable, and
