Dindigul.—The climatic conditions and the state of the water were much alike
in the two years. No sign of a much needed improvement in 1910, there being
organisms of Class I present in the Deep well. In 1909 such were present in
the water of the distributary system. Chemically the water, though hard and
containing sulphate, is not very bad.
Madura.—This year there has been considerably less rain than in the
corre-sponding quarter of 1909 and the river-bed was dry when the samples were collected.
This did not appear to have made any difference however, as most objectionable
pollution was present both years. The water from the distributary system was
rather better however so that it may be said that the efforts to improve a most
unsatisfactory supply was having some practical outcome. It is a pity that more
cannot be done to keep the river from being polluted.
Kurnool.— With approximately similar meteorological conditions the water of
the Cuddapah-Kurnool Canal was if anything a shade better this year but there
is not much to boast about. The results got with samples from the distributary
system are however depressingly bad as compared with last year. It is impossible
to believe that such results would have been got had the settling tanks been worked
in an intelligent manner as recommended by Major Clemesha in his report for
March 1909.

so that no comparison is possible as to the raw water. The stored water was
however very much better in 1910, but this only serves to accentuate the
deterioration of the water brought about by filtration. The filtered water from the
old bed, the only one working in 1909, is very bad by comparison in 1910. The
so-called pipe action exerted a beneficial effect in both years.
Ootacamund.—There
had been nearly twice as much rain in 1909, but this did
not make much apparent difference on the quality of the water. The water-supply
of Ootacamund is remarkable for the varying results got from the various sources
at different times. The water from one or more sources is always extraordinarily
pure, but frequently astonishingly bad results are got. For this quarter in 1910
the Old Ooty Cistern and the Kodappamund foot the list, the water from the former
being astonishingly bad though hard pressed by the latter.
Conjeeveram. — There has been comparatively little rain this year and the water
from the Collecting well was not so good. No sample was taken from the Spring
on this occasion so a comparison cannot be made. In 1910 pipe action seems to
have replaced effective filtration in 1909, the water as distributed being rather
better on the whole.
Vizagapatam.—There
was considerably less rain than in 1909 and the water
was very definitely worse. Filtration brought about a corresponding, though by
no means satisfactory improvement. The water as drawn from the distributary
system was not so good.
Gudiyáttam.—There
was rather more rain in 1910 but the water from the
Gallery was much the same in both years. No improvement can be recorded with
reference to the water after treatment. In 1909 the quantity of pollution was
greater, in 1910 the quality of the pollution was on the whole more objectionable.
Organisms indicating recent and probably dangerous pollution were present in the
water as distributed in both years. Not a state of things to be proud of.
Vellore.—Owing
to redistribution of the order in visiting water-works there is
two months' difference in the time that the samples were taken in the two years.
No very effective comparison can therefore be made. In 1909 there had been very
little rain in the interval, in 1910 a good deal. In both years the amount of
pollution in the water was the same for the tank and the filter supply, but the kind
is altogether against 1910 when the pollution was of a recent and dangerous kind.
The same pollution, though in reduced amount, was found in the distributary
system, whereas there was notable improvement in 1909. Vellore progress for the
year is definitely retrograde.
