30 OLDHAM : THE ALLAH-BUND 



in spite of the long period during which it was dry— it would have 

 been quite possible for the flood waters to have forced their way 

 through the old channel instead of forming a new one round the end 

 of the elevation, said to be some 50 miles long. There would cer- 

 tainly be some ponding up of the flood waters above the barrier, 

 but this might easily have been regarded as a natural accompaniment 

 of the flood, or have escaped notice altogether, as the country 

 had been depopulated. 



On the other hand, and opposed to the arguments which can be 

 urged against an elevation, we have the map and section, and the 

 very definite statement, evidently based on careful levelling, that 

 there was an actual upward slope of the ground immediately behind 

 the southern scarp of the Allah Bund. 1 here seem, consequently, 

 good grounds for maintaining the older view that the Allah Bund 

 was an elevated tract, but there can be no doubt that the estimates 

 of its height do not correctly represent the amount of elevation, but 

 of the sum of this and the depression which certainly took place to 

 the south. The former cannot have exceeded 10 feet, the latter 

 amounted to as much or more, and the two together represent the 

 estimates of the height of the barrier as seen from the south, esti- 

 mates which range up to 20 J feet.
