?30 At the hill Sanitarium of Tárágarh the drinking water supplied to the con- valescents is obtained from the Doodea well in the city of Ajmere. The analysis published in the report on Nasirabad shows that it is a most unsafe drinking water. At Nasirabad the troops are at present supplied from two wells, only one of which is proved by analysis to contain good water. A reservoir, regarding which full details are given in my report on that station, has been constructed among the hills about five miles from the Camp, and although the water from it, owing to a large amount of vegetable contamination, is not at present fit for immediate use, I am confident when the filtering and storage arrangements have been improved that it will yield very good water. The inhabitants of the Sadar Bázár are at present solely dependent for their drinking water on diggies and surface wells, the water in which is simply sewage; and until the Danta Lake water, supplemented from the Bir tank, can be brought into the bázár, its condition must be a standing danger to the troops. The Analyst made a very complete analysis of all the waters at Nasirabad. At Neemuch the water-supply is solely derived from wells sunk in the late- rite rock. The troops obtain their supply from the hospital well, which contains water of good quality, but which is open to danger, as I have explained in my report on that station. The water in the wells in the Sadar Bázár at Nee- much is very impure and is a source of danger to the troops frequenting it. The analyses are embodied in the report. At Indore the water for the troops is obtained from a well sunk on the black cotton soil. As this is open and situated close to a public road, it must, at all times, be liable to pollution. At Mhow the water-supply is derived from surface wells, many of which are at a lower level than the barracks, and they are at all times liable to be contaminated by surface impurities. Full details regarding the water supplied to the troops and that used in the Sadar Bázár, which is most impure, will be found in my report on that station together with the analyses made by the Analyst. At Asirgarh the drinking water for the detachment is obtained from a well sunk on the banks of the Sukkur Tank. Drains have with great judgment been made to cut off water flowing over inhabited areas from finding its way into the drinking water-supply and to convey it into another tank at a lower level. The catchment area of the tank is formed by the parade ground and the greatest care is taken to keep this clean. The tank water is filtered through sand before it passes into the well, and the beneficial effect of this treatment in reducing the amount of organic matter is seen from a comparison of the water taken from the tank and that from the well:- Parts per Million. Free Ammonia. Albuminoid Ammonia. Sukkur Tank ˇ026 ˇ7 Well Nil. ˇ13 Do. after passing through the Macnamara filter Nil. ˇ09 The water from the two nálás on the road from Chandni Railway Station to Asirgarh and that from a well and the nála at Chandni is in each instance bad.
