Smoke Abatement
During the year 26 observations of factory chimneys were
made, and in 3 cases contraventions of the Council's bye law
limiting black smoke emission to two minutes in half-an-hour were
observed. Notice of the nuisance was served in each case.
Swimming Baths.
The Corporation provide public swimming baths, comprising
a major and minor swimming bath, and also special baths.
Samples of water from each of the baths were submitted for
chemical and bacteriological examination.
The results of the examinations of water from the major nnd
minor baths were satisfactory, but consideration should be given
to extending chlorination to the small plunge bath.
Eradication of Bed Bugs
The number of Council houses disinfested during the year was
39, and the number of other houses disinfested by the Corporation
for owners was 37.
The method employed by the Corporation consists of fumigation
by a 5% by volume concentration of sulphur di-oxide, and
supplementary spraying with contact insecticides.
Household effects of tenants transferred to Council houses
are disinfested by hydrogen cyanide. The van method carried out
by Contractors is employed. The tenants are circularised on
methods of preventing reinfestation.
Housing
After prolonged consideration and delay the Council decided
to proceed with the erection of 74 houses to rehouse displaced
tenants from clearance areas and overcrowded houses, the requirements
of both being satisfied by houses of the interlocking or
adjustable types.

resulted in a diminution of known cases of overcrowding. From
