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



Kamarhati. — This Municipality lies immediately to the north of 

 Baranagar, and consists of two Wards, namely, No. I. between the river 

 and the Grand Trunk Road, and No. II. from the latter up to the 

 Eastern Bengal Railway, and including Belguria. The spleen-rate of 

 the river Ward was found to be 188, while that of the inland Ward was 

 34'8, a notable difference, while the first Ward mainly relies on the river 

 for its water-supply, and the latter is dependant on tanks ; for although 

 there are a few wells in all the municipalities, mostly belonging to 

 private individuals, yet they appear from my inquiries to be little if at 

 all used by the people for drinking purposes, especially if filtered water 

 is available, while many intelligent natives informed me that those who 

 drank filtered water suffered much less than those who drank that from 

 any other source, including well water. The ground water was 7 feet 

 below the surface in February in the riverine Ward, and had been within 

 1 ft. 8 in. of it in the rainy season of 1899, while it was 1 foot further 

 down in both seasons in the case of the eastern Ward, so that from this 

 point of view the latter should have been slightly the more healthy of 

 the two, instead of entirely the reverse obtaining.

North Dum Dum. — This Municipality is situated to the east of 

 Kamarhati, and extends from the railway to Nowi Nadi, a distance of 

 some four miles, and it consists for the most part of rice fields surround- 

 ing several villages. It contains two Wards, the westernly of which 

 includes the large village of Nimta, while the easternly one includes 

 Gouripur and Kadihati, which are situated on the Nowi Nadi, a slug- 

 gish stream which carries the surface drainage away to the south-east 

 into the Kocho bhil. The water-level in a well in the western Ward was 

 7 ft. 3 in. below the surface in February, and had risen to within 2 ft. 

 3 in. in the rainy season of 1899, so that this part is certainly water- 

 logged. The spleen-rate in the western Ward was no less than 766 per 

 cent., while among 58 boys of the Nimta High School, who mostly be- 

 longed to well-to-do families, it was 67. In the eastern Ward the per- 

 centage worked out at 59*6, which is also very high, the average of the 

 two Wards being 68*1 j an extremely high figure. The water-supply is
