Periyakulam. —Consistently good results at three consecutive examinations were obtained
with this water-supply. The sand filters here were being worked with advantage.
Salem.—In January the samples just passed muster. In July and October the examina-
tions showed that the sand filters were not improving the supply. A grossly polluted tank at
Arasipalayam which had been constituted into a water-supply to the neighbouring village was
condemned during the year.
Tanjore.—Very variable results were obtained with this water supply. In February and
December when the water in the river was reduced to a mere trickle, the gallery supply was
very fair. During the floods in July the water was poor.
Trichinopoly.—Samples examined in May and September were found to give fairly good
results.
Tirupati. —In March the results of analysis were very good. In July a s light deteriora-
tion was manifest.
Vizianagaram. —In June the supply was very fair. A marked deterioration was noticed
at the December examination.
Vizagapatam. —The results of three consecutive examinations during the year showed
that beyond a slight reduction in the quantity of suspended matter, no improvement from the
bacteriological point of view was effected by the sand filters.
Vellore.—Three examinations showed that no benefit was being derived from sand
filtration.

Berhampore. —Two wells have been in use at this Jail. Both of them showed evidence
of organic and bacterial pollution at three consecutive examinations and just passed muster.
Bellary. —The water-supply of the Bellary Jail has been examined three times during the
year. The results were uniformly bad. On two occasions in November 1918 and May 1919
vibrios were detected.
Cannanore.—Samples of water from six different wells have been examined systematically
from this Jail. How many of these are actually used for drinking purposes is not known.
Three of these were condemned in May 1919 as unfit for drinking purposes. Two were fair
but one of these has since deteriorated.
Coimbatore. —The supply to this Jail is derived from two wells the waters of which are
very bard and contain high figures for total solids and chlorine, features typical of the wells
in the district. Bacteriologically they have just escaped being condemned.
Cuddalore. —Two wells, one of which is inside the Jail and the other outside, are used
for drinking purposes. The well inside the Jail has yielded consistently poor results while the
quality of the lake well water has been liable to fluctuations.
Palamcottah.—The well of this Jail is liable to seasonal variations and the bacteriological
findings have never placed the well above reproach.
Rajahmundry.—The water from a well in this Jail is stored in an elevated reservoir and
supplied to the Jail. Analysis of the water has given bad results. The improvements which
have been lately carried out have not as yet made themselves felt by a corresponding improve-
ment in the water.
Salem. —Three consecutive examinations revealed the presence in the water of gross
organic and bacterial pollution.
Tanjore. —The water of the Jail well just passed muster in April. In September signs of
improvement both from the chemical and bacteriological points of view were manifest.
Vellore. —The well is not in a satisfactory condition. The results of three consecutive
examinations have all been bad.

RAILWAY STATIONS.
Bangalore City and Cantonment.—In March the water as supplied was fair although the
figures for albuminoid ammonia were slightly in excess. In July the water was discoloured
and had deteriorated.
