C. G. Rockwood—Notices of recent Earthquakes, 43 
nes. The destruction of property was estimated at $12,000,000. 
Up to April 24, the vibrations still continued and the Govern- 
ment Palace had at last fallen. The neighboring voleano of 
Izalco was in eruption at the time of the earthquake. 
San Salvador was situated on a small stream about 30 miles 
from the seaport of La Libertad, with which it was connected 
by rail. It contained about 15,000 inhabitants. This is the 
eighth time the city has been destroyed by an earthquake in the 
last 150 years. The last catastrophe occurred on the evening 
of Kaster Sunday, April 16, 1854. 
The following description of the crater of San Salvador, on 
the slope of which the city is built, is given by a party who 
made the ascent in January last. After describing the ascent 
the writer says: ‘Suddenly and .without expecting it they 
found themselves on the edge of an abyss; the impression from 
the sudden view of it brought everyone to a stand-still, to con-

cavity suddenly yawned before them, about a kilometer wide 
and 400 yards deep, representing an inverted cone, but lined 
with an exuberant vegetation and ending in a lake at the bot- 
tom. After due consideration of the scene before them, with 
tespect to the probable date of the last eruption, of which no 
tradition exists, and taking into account the thick stratum of 
vegetable mould, the size of the trees that grow at the bottom 
and sides of the crater, and the formation of basalt, it was cal- 
culated that this volcano has not been in activity for at least 1000 
ears
