EARTHQUAKES. 
big weeds of one hundred acres of the land of Letterbrocken, 
part of the property of the Provost of Trinity College in Joyce 
County, and consisting of prime pasture and mountain, on which 
a number of tenants resided, commenced moving and carrying 
with it huge rocks, immense masses of earth, the entire crop: of 
wheat, oats, potatoes, &c., precipitated the whole into the sea 
and disappeared. Previous to its movement, a great noise was 
heard for some time, and the ground was convulsed. It is sup- 
posed that the previous drought which had occurred, prepared 
the way for this phenomenon, Two days after, a large tract of 
land thickly inhabited, the property of R. Martin, Esq. M.P., in 
the same neighbourhood, was visited by a like phenomenon, but 
even of a more destructive nature ; the loss of the sufferers not 
being confined to their land and crops, but their entire stock and - 
property being swallowed up by the earthquake. These occur- 
rences are mentioned in the Gent. Mag. for November, from 
the Tuam Gazette, and their date given as ten days previous. 
_ The Batavian Journals of April give an account of an earth- 
quake very destructive in its effects which took place on the 29th 
of December 1820, on the south coast of Celebes. It did im- 
mense damage, particularly at Boelekomba, where the sea rose 
several times a prodigious height, and then falling again with 
great rapidity, alternately deluged and left the shores, destroying 
all the plantations from Bontain to Boelekomba. Many hundred 
persons lost their lives. The forts of Boelekomba and Bontain 
were much damaged. 
On the 4th of January this year, another shock of an earth- 
quake occurred in the same neighbourhood. 
On the 17th February, at half-past five in the afternoon, se- 
veral smart shocks of an earthquake were felt at Comorn, in Hun- 
gary. The first, which lasted full three seconds, was SO severe, 
that the church of St..Andrew was cracked in several places, and 
many chimneys of the barracks were thrown down. But the ef- 
fects of this awful phenomenon were much more sensibly felt at 
the village of Izso, about two leagues from Comorn, where not 
only the Catholic and the Protestant church were greatly da- 
maged, but six houses wholly thrown down, and a quantity of 
eattle buried under their ruins. 
- Some slight shocks of an earthquake were experienced at Pres- 
burg on the 18th of February, at five in the afternoon. 
_ On the 19th of February, au earthquake occurred which was 
felt at places very distant from each other. It was felt at Paris, 
at Lyons, and still more violently in Switzerland. At Bourg, 
three distinct but immediate shocks were felt. The first was 
attended with a loud detonation ; the third was longer and more 
smart,
