very violent, especially beyond Caurimare, in the 
valley of Capaya, and as far as the meridian of Cape 
Codera, while they were very feeble on the coasts 
of New Barcelona, Cumana, and Paria, though 
these shores are known to have been formerly shaken 
by volcanic vapours. ap | 
Fifteen or eighteen hours after the great catas- 
trophe the ground ceased to be agitated ; but subse- 
quently to the 27th the tremblings recommenced, 
and were accompanied with very loud subterranean 
noises. Frequently not less than fifteen oscillations 
were felt in one day. On the 5th April there was 
an earthquake almost as severe as that of the 12th 
March. ‘The surface was in continuous undulation 
during several hours, large masses of earth fell in 
the mountains, and enormous rocks were detached 
from the Silla. 
While violent agitations were experienced in the 
valley of the Mississippi, in the island of St Vin- 
cent, and in the province of Venezuela, a subterra-

the Rio Apure, over the space of four thousand 
square leagues. This sound began at two in the 
morning of the 30th April, and was as loud on the 
coast as at the distance of eighty leagues. It was 
every where taken for the firing of guns. On the 
same day a great eruption of the volcano of the 
island of St Vincent took place. This mountain 
had not ejected lava since 1718, and hardly any 
smoke was issuing from it, when in May 1811, fre- 
quent shocks occurred, and a discharge of ashes, at-

the 27th April next year. On the 30th the lava
