ing inhabitants. ‘The rumbling noise from the bog gave the alarm, 
and on the 30th it burst, and a kind of lava issued from it, which 
took its direction towards Ballygriffen and Golden, overspreading 
and laying waste a vast tract of fine fertile land belonging to John 
Hide, Esq. Everything that opposed its course was buried in 
ruins. Four houses were totally destroyed, and the trees that stood 
near them torn up by the roots. ‘The discharge has been incessant 
since the 30th, and how far it will extend cannot at present be 
determined.” 
A.D. 1809, 16th December.—Bog of Rine,Camlin River, Co. Long- 
ford.—‘“ In the night, during a thunderstorm, about 20 acres of 
the bog burst asunder in numerous places, leaving chasms of 
many perches in length, and of various breadths, from 10 feet to 
3 inches. The rifts were in general parallel to the river, but in 
some places the smaller rifts were at right angles to it; not only 
the bog, but the bed of the river was forced upward; the 
boggy bottom fillmg up the channel of the river, and rising 
3 or 4 feet above its former banks. In a few hours 170 
acres of land were by these means overflowed, and they continued 
in that state for many months, till the bed of the river was cleared 
by much labour and at considerable expense.” The bog had been 
an unusually wet one. It did not sink in any particular place. 
“Several earthquakes were felt in distant countries about 16th 
December, . . . and it is not absolutely impossible that a com- — 
munication may exist between them” [the earthquake and the 
bog-slide. } 
A.D. 1819, January.—Owenmore Valley, Erris, Co. Mayo.—“ A 
mountain tarn burst its banks, and heaving the bog that con- 
fined it, it came like a liquid wall a-down, forcing everything — 
along, boulders, bog timber, and sludge, until, as it were in an 
instant, it broke upon the houses [of a small village], carrying 
all before it, stones, timbers, and bodies, and it was only some 
days after, that at the estuary of the river in Tullohan Bay, the 
bodies of the poor people were found.””*
