kind attended the events of 1819 ; and it would indeed so far remove any- 

 immediate link between the presence of igneous rocks in the district and 

 its earthquakes, that the latter would come to represent only the recurrence 

 of widely separated periodic seismic disturhancesj which might have been 

 expected to take place beneath a long-quiescent region situated in one 

 of the chief belts of volcanic action traversing the globe.

1819. The accounts given point plainly enough to the fact of some per- 

 manent depression of portions of the Eunn to depths not exactly known, 

 but in the case of ' Sindree' sufficient to submerge all but a small part 

 of the highest tower of the fort. The original height of this fort is un- 

 recorded, but such buildings in this country are generally carried up to 

 about 16 feet. 



The access of the sea water to the Sindree basin may have been 

 assisted by a great sea wave resulting from the shocks and the undulation 

 of the o-round may probably have forced out water from the silts forming 

 the bed of the Runu sufficient to considerably augment the quantity 

 which sought the lowest level in the Sindree depression. 



That the subsidence was not entirely confined to this place would 

 appear from a note on Sir A. Burnes' map, that a dJwoi or hei/t [' Dera 

 bet') near Balliaree on the north side of the Runn was joined to the 

 mainland before the earthquake of 1819; and a depression of some low 

 lands near Nurrha on its south shore is mentioned by Colonel Grant as 

 having occurred at the same period.
