more than 2 feet per mile or double that of the whole of the Indus 

 from Attock to the sea* If the height of the mound be supposed even 

 half of that stated by Captain Baker^ bringing it to the amount recorded 

 by Lyell, the fall of 1 foot per mile would still seem too gi-eat for the 

 old river to have had before the earthquake ; and further, as the Koree or 

 Pooraun was replenished by distributories of the Indus, its fall, according 

 to Mr. Fergusson, may not have been more than six inches to the mile, 

 while if the general flatness of the locality be considered, it was probably 

 much less. 



Had the former channel of the river possessed any considerable 

 depth where the Allah Bund was formed, this ought to be deducted from 

 the assumed elevation, but Burnes says, (p. 312), 'above Sindi-ee it 

 filled with mud and dried up/ From this it would appear hardly 

 possible that after the presumed elevation of the Allah Bund, the country 

 still retained sufficient slope to allow of the Indus flood of 1826 following 

 the old channel southwards, and the fact of its being elevated to any 

 considerable extent becomes somewhat doubtful. 



The sectional profile supplied by Captain Baker shows the summit 

 of the Allah Bund to be at the same level as the bank of the Goonee 

 (a tributary to the Pooraun river) where the Mora Bund has been 

 constructed thirty-seven miles to the northward of the former place. 

 From this Mora Bund the bank is shown to decline regularly until 

 within about four miles of the Sindree depression, when it commences 

 to rise to the Allah Bund, gaining there a height of about 19 feet 

 above its lowest point ; so that if the channel of the river had become 

 filled up, as Burnes states, before the earthquake, this profile would lead 

 to the supposition that an obstruction 19 feet in height and four 

 miles in width was insuflacient to divert the river from its old channel.
