The gas, like the water, is submitted to regular analysis by the staff
of the sanitary officer, and any fault which may be detected, and
which indicates a departure from the standard of purity framed by the
Municipal Council, is immediately remedied, both gas and water being
exclusively under the control of the local authority.

The inspectors of the sanitary officer have under them a body of
scavengers. These, each day, in the early morning, pass through the
various districts allotted to them, and remove all refuse in closed
vans. Every portion of manure from stables, streets, and yards is
in this way removed daily, and transported to the city farms for
utilisation.

Two additional conveniences are supplied by the scientific work of
the sanitary establishment. From steam-works steam is condensed, and
a large supply of distilled water is obtained and preserved in a
separate tank. This distilled water is conveyed by a small main
into the city, and is supplied at a moderate cost for those domestic
purposes for which hard water is objectionable.

The second sanitary convenience is a large ozone generator. By this
apparatus ozone is produced in any required quantity, and is made to
play many useful purposes. It is passed through the drinking water
in the reserve reservoir whenever the water shows excess of organic
impurity, and it is conveyed into the city for diffusion into private
houses, for purposes of disinfection.

The slaughter-houses of the city are all public, and are separated
by a distance of a quarter of a mile from the city. They are easily
removable edifices, and are under the supervision of the sanitary
