WATER SAMPLES TAKEN—9TH SEPTEMBER 1912.
Remarks. —The Samalkota Canal was in floods when samples were taken. The canal water
was not allowed to run into the settling tank, as there was about 6 feet of
water in the tank. The supply is intermittent. There has been about 14.74
inches of rain since last analysis.
