which the odour of paint is communicated to water. Cisterns
arc often situated over water closets. The waste pipes to
cisterns are in almost all instances connected with the
water closets, or enter the drain direct: they are carelessly
trapped, blowing off sufficient sewage gases to contaminate
the water. A portion of water is also detained for a long
time in cisterns, and they frequently have their covers
removed, and the water is exposed to the rays of the sun.
In many instances they are seldom or never cleaned, and
their sides become slimy and offensive. And in most
instances potable water is not filtered domestically before
use.
For these, amongst other reasons, great benefit would
have accrued if the Water Acts of 1852 and 1873 had been
successful in obtaining a constant supply of water to the
residences in this district.
1874.—The purity of water does not entirely depend
upon the source of supply. Major Bolton, in his reports
upon water supply, calls attention to a most important point
which I have frequently mentioned to the Board, viz.: the
filthy state of cisterns.
Milk.
1856.—Animal food rendered poisonous by disease or
decay.
I may also mention milk from diseased cows; and where
these animals arc kept without a supply of proper food, fresh
air, light, and exercise, and in the midst of offensive refuse,
this may, I think, be more often a cause of disease than is
anticipated.
1856.—The health of the population of any district in
my opinion materially depends upon the quality of the milk
supplied, especially as the main support of children is from
this source; and the purity of milk much depends upon
the manner in which cows are kept, as to food, water, air,
exercise, and amount of space, ventilation, and cleanliness of
cow-houses.
