1837.] at Chandpur, on the Delhi Canal. 53 



I was obliged to commence sinking perpendicular, which was carried 

 on till we at length found water at 72 feet deep. The boulders 

 found in the latter part of the work were only few, but they were of 

 the largest size, and those were got rid off by excavating recesses 

 in the sides and depositing them therein. The above excavation down 

 to 72 feet was completed for 120 sicca rupees. 



Part of the cylinder having been built, it was sunk in June, where 

 I found the water had sunk 7 feet 6 inches lower. We sunk further 

 14 feet, when we got to a bed of clear pebbles, and bedded the well 

 ring on small boulders, with 6 feet 6 inches water ; and as the driest 

 season has arrived, we may expect always to have a plentiful supply 

 of good water from a total depth of 86 feet below the surface.
