TRICHINOPOLY.
WATER SAMPLES TAKEN—17TH APRIL 1910.
REMARKS.—The water was not flowing in the river Cauvery when samples were collected. But the samples were taken from water
which was allowed to stand over the gallery to increase the yield. The supply is intermittent. There has been
about 1·97 inches of rain since last analysis. The supply is inadequate during this part of the year.
