470 L. Rogers — Relationship of the water-supply, water-logging [No. 4, 



Municipality] rises to 1 55*5 per cent., or just over two-and-a-half times 

 as great as among the filtered water drinkers. A well in the northern 

 part showed a water-level 9 ft. 6 inches below the surface of the ground 

 in February, while it had risen to within 1 ft. 6 in. during the rains of 

 1899, so that there must have been a considerable degree of water- 

 logging at that time, in spite of which the spleen-rate is low. These 

 facts appear to admit of no other explanation than that the filtered 

 water-supply was the cause of this low rate near the Mill as compared 

 with a precisely similar area in other respects close by which had not 

 the advantage of the stand-pipe water.

Bhatpara. — This Municipality consists of a narrow strip between 

 the river Hooghly and the Eastern Bengal Railway and to the north 

 of Garulia, and it is divided into three Wards, the northern two, Wards 

 I. and II. of which, more particularly, and to a somewhat less extent 

 the southern one, Ward III., obtain some filtered water from the Mills 

 situated within this area. The spleen -rates of all are low, that of the 

 southern one being slightly higher than the other two, although there 

 is not much difference in their water levels, which are slightly in favour 

 of Ward III. The figures are given in Table XIII. below.
