finding no bottom with twenty fathoms of line, concluded it was an 
earthquake. Ona subsequent visit to Talcahuana, his suspicions 
were confirmed, in the desolation and ruin which that once thriving 
port, then presented ; as also in the fact, that the water in the bay 
was five or six feet lower than its usual depth. Talcahuana has 
been the general resort of American whale ships for several years 
past—the harbor being one of the best on the coast. The town is 
situated almost on a level with the sea, large hills rising in the rear. 
Capt. T. states that he has been on the coast of Chili a number of 
voyages during the same month, and thinks he never knew such a 
scarcity of whales, fish, and fowls, as in the present year. It isthe 
general opinion that the earthquake has had a tendency to drive 
them from the coast, The shock was very sensibly felt by Capt. 
Cotton of ship Loper, six hundred miles from land.—N. Bedford

Early in March several shocks of an earthquake were felt at F'lo- 
rence, which seemed to shake the houses to their foundations.

Vesuvius.—On the evening of the 2d of April, there was anoth- 
er explosion of Vesuvius. The shocks were so violent that the five 
craters vanished, and were all united to one frightful abyss. Im- 
mense masses of rock were projected to a vast height, and fell like 
a tremendous shower on the ribs of the mountain.
