tract pf Chili was similarly shaken, a permanent rise of 

 two feet following the former earthquake, and a rise of 

 eight feet the latter. 



The earthquake which took place at Cutch in 181 9 is 

 perhaps in some respects yet more remarkable. In this 

 instance, phenomena of subsidence, as well as pheno- 

 mena of upheaval, were witnessed. The estuary of 

 the Indus, which had long been closed to navigation 

 being, in fact, only a foot deep at ebb-tide, and never 

 more than six feet at flood was deepened in parts to 

 more than eighteen feet at low-water. The fort and 

 village of Sindree were submerged, only the tops of 

 houses and walls being visible above the water. But 

 although this earthquake seemed thus to have a land- 

 destroying, instead of a land-creating effect, yet the 

 instances of upheaval were, even in this case, far more 

 remarkable than those of depression. 'Immediately 

 after the shock,' says Sir Charles Lyell, ' the inhabi- 

 tants of Sindree saw at a distance of five miles and a 

 half from their village a long elevated mound, where 

 previously there had been a low and perfectly level 

 plain. To this uplifted tract they gave the name of 

 Ullah-Bund, or the " Mound of God," to distinguish it 

 from several artificial dams previously thrown across 

 the eastern arm of the Indus. It has been ascertained,' 

 he adds, ' that this new-raised country is upwards of 

 fifty miles in length from east to west, running parallel 

 to the line of subsidence which caused the grounds 

 around Sindree to be flooded. The breadth of the ele- 

 vation is conjectured to be in some parts sixteen miles,
