composed entirely of tabular and nodular basalt. It is 500 

 feet in depth, and three or four miles in circumference. In 

 the bottom of the hollow is a lake five feet deep, the waters 

 of which are impregnated with muriate and sulphate of soda, 

 and sulphate of lime. Subcarbonate of soda prevails in the 

 neighbourhood. In 1851, it was examined by Dr Bradley 

 who met in with abundance of scoriae in the neighbourhood 

 and was able to trace a vast stream of lava to the east and 

 westward. The great intervals betwixt the points of vol- 

 Cft^ipi ^.etivity in this part of India, even when connected by 

 hot springs, prevents them from being associated as groups 

 anywhere betwixt Arracan and Cutch. 



On the 27th May 1846, a hill on the Nerbudda, called 

 Dunnh Phai, or Smoking Mountain, about 500 feet high above 

 the plain, gave out alarming moans, to the terror of the 

 neighbourhood, and then an enormous outburst in it oc- 

 curred. The appearance this presented, when examined 

 shortly afterwards by Col. Skene and Lieut. Briggs, was 

 such as might have been produced by the explosion of a 

 mine, making a rent in the hill, from top to bottom, about 

 thirty feet across and six feet deep. Great trees were upset 

 by it, and the rocks rent twenty to thirty feet in pieces, as 

 if blasted by gunpowder, and thrown to the opposite sides of 

 the fissure. The appearance presented in no way resembled 

 that of a land-slip, — the bursting force had obviously been 

 from the interior. It was not stated that any erupted matter 

 had been thrown out ; there was no appearance of any vol- 

 canic swells in the neighbouj?bi^ad,>a!ad.jio^ta?aditiQUfi»£rV<ikar

In the end of October 1849, something like an ebulli- 

 tion of pestilential gas, the discharge probably of a subma- 

 rine volcano, occurred off Porebundor, in Kattiawar, and was 

 manifest for thirty or forty miles out at sea ; the fish were 

 poisoned by it, and for days lay floating in myriads on tke 

 surface of the water. t h'.'^rCm-'
