flnctnatiDg level of the water in the Sindree Lake. Its length appears 

 to correspond with that of this depression ; but its width is said to vary 

 from two to ten or sixteen miles, that is to say, the whole tract from the 

 Sindree depression to the margin of the laana or Runn near Raoma-ka- 

 hazaar has been looked upon as elevated, apparently because no abrupt 

 slope such as exists to the south was observed on the north side of the 

 Allah Bund. 



Captain Baker, the only person who records the existence of any 

 northerly slope, says that it is very gradual, and that the bottom of the 

 dry channel crossing this bund or mound was 7 feet higher than some 

 salt water pools, remaining in the same channel fm-ther up nearer to 

 Raoma-ka-bazaar ; but as he gives the depths of other parts of the channel 

 as varying from 12 to 20 feet, this may not be extraordinary. 



To decide this point of the real or apparent elevation of the Allah 

 Bund and explain existing discrepancies, some further levelling would 

 be necessary. Mere inspection of the ground, as described by Shaik 

 Kasim, could add little or nothing to what is already known; and 

 though the opinion of Sir A. Bm-nes and Captain Baker's detailed section 

 should carry weight, the great fact of the Indus flood finding its way into 

 the Sindree basin by following the old channel across a belt of elevation 

 four, or sixteen, miles in breadth, instead of accumulating on the 

 upper side of the obstruction and finding a new passage round one end, 

 is worthy of consideration. This fact becomes intelligible only (in case 

 of the mound having been really upheaved) on the supposition that a 

 greater fall than the height of the mound existed between it and the 

 Sind margin before the earthquake ; and that after the general eleva- 

 tion of the intervening space, sufiicient fall stiU remained to enable the 

 stream to follow its old direction. 



Taking the height of the mound at about 20 feet as given by 

 Captain Baker, and allowing the distance from the Sind edge of the 

 Ruun to be so much as ten miles, this would give the old fall as something
