1050* Memoir on Indian Earthquakes. £No. 144. 



" At Lalettee, Selcope Chukla, the ground in some places opened'and 

 threw up great quantities of salt water, and in others entirely sunk ; the 

 channel of several creeks and little vallies between the hills were filled 

 up with great quantities of sand ; in some places, the water still conti- 

 nues twenty cubits deep, and in others unfathomable. 



" Silluk creek and Islammuttee river are both stopped up ; several 

 boats laden with goods then coming down, are not now able to get out 

 of them : the country around there opened greatly in some places, and 

 in others, entirely sunk : and a great many tanks filled with sand. 



" Bur Coller hill opened about forty cubits wide. 



" Sess Lung, Joom hill, one of the Mug mountains, is entirely sunk. 



" Chungee hill opened between twenty and thirty cubits. 



" Padoorah Creek, at that time without water, opened and threw up 

 two hills of sand : and all the houses in these parts were broke down. 



" Joom Chatea Pedea hill is sunk so low, that its top is now on a 

 level with the plains. 



" Rigerry hill, which was very large, opened thirty cubits wide. 



" Joom Palang hill opened twenty-five cubits. 



"By the accounts already come in, there are 120 dons* of ground 

 lost in the different parts of the province ; but these I am afraid will 

 not be one-eighth part of the whole damages, as we have farther rela- 

 tions coming in every hour. 



" As we are informed that two volcanoes opened, 1 am in great 

 hopes these will prove a sufficient vent to discharge all the remaining 

 sulphurous matter in the bowels of these countries, and put a stop to 

 any farther Earthquakes here, at least for many years to come." 



The hope, with which this paper closes, would seem to have been 

 realised, as no farther shocks of severity from 1762 to the present time, 

 are recorded, as having occurred in the province of Chittagong. 



We have but very limited accounts of the effects of the Earthquake 

 of 1762 upon the Arracan coast in general ; but its influence on the 

 Island of Chedooba, as described by Captain Halsted, (J. A. S. Vol. X. 

 p. 433, &c.) may be taken as a specimen of what occurred, in all pro- 

 bability throughout the entire archipelago of volcanic islands which 

 skirts that interesting coast. The whole of Captain Halsted's remarks 

 are so intimately connected with my subject, that finding a difficulty 

 in making a selection, I have thought it preferable to quote them in full. 



" The geology of Chedooba," Captain Halsted remarks, " presents 

 characters of so much general interest, that any report on this island 

 might be looked on as imperfect in which the subject was wholly 

 omitted. 



" But as it is intended in a separate notice to give such details as may 

 render the subject capable of investigation by those able and interested 

 in the science, the present one will be confined to a mere statement of 

 the general features exhibited. 



* One sye don of ground is 1,920 cubits long, and 1,600 cubits broad.
