' 36 WTNNE : GEOLOGY OF KXJTCH. [PAUT I. 



Ten years after the visits of Sir Alexander Burnes, at Sir C. 



Lyell's request, a native surveyor was sent to make 

 183S 



a plan of ' Sindree' and the ' Allah Bund/ In 



the month of March he found the channel traversing the 'bund' to be 



100 yards wide, without water, and encrusted with salt, and was told 



that it only contained 4 or 5 feet of water after rains. The sides or 



banks were nearly perpendicular, and 9 feet in height. The ' lagoon'' 



had diminished both in area and depth, and part near the fort was dry 



land. 



In 1844 the Allah Bund was visited by Captain (now General) Baker, 



of the Bengal Engineers. On the 11th of July, he 

 184-1. 



found the ' mound,' where cut through by the 



Pooraun (or Koree), nearly four miles in width, but in other places it was 



said to vary from two to eight miles. Its greatest height was on the 



borders of the lake, above the level of which it rose 20f feet. " From 



this elevation it gradually slopes to the nortJmard till it iecomes undis- 



ilnguisliahle from the js/flMi." The bed of the Pooraun was 1 foot 



higher than the level of the lake ; and 7 feet above that of a chain 



of pools of salt water in the same channel nearer Lallah Puttun Bund 



to the north (called Bundrejo Duryao), three koss from the Allah Bund.* 



This is the only observer who mentions that the Allah Bund had 

 any slope on the north side ; and the section submitted with his report to 

 the Sind Government shows a slope in that direction from the line of 

 depression northwards, amounting to 19 feet in tour miles. 



Mr. DaCosta, of the Great Trigonometrical Survey, visited Sindree
