"It does not appear that there is any hope of improvement of the quality
of water available for dilution—except the natural improvement due to increased
freshwater flow—until the standard of purification of the sewage effluent in the

agents which will oxidise the more readily putrescible matters in the effluent
as at present discharged rather than merely as heretofore to attempt to fix,
without oxidising, constituents which might cause odours."
Offensive Trades.—By the Transfer of Powers Order, 1933, consideration of,

offensive businesses, or imposition, modification, or removal of conditions, was

In Woolwich, however, there is only one offensive trade, namely, that of a slaughterer
of poultry. The premises were approved by the London County Council in November,
1931.
Rag Flock Act.—Two samples of rag flock were taken for analysis. Such
material must comply with the Rag Flock Regulations, in which it is laid down that
the soluble chlorine in the form of chlorides must not exceed 30 parts of chlorine
in 100,000 parts of flock. Both samples complied with the Regulations, as the
results of analyses show, the number of parts of chlorine being, respectively, 3 and 4.
Mortuaries.—The Public Mortuary is in Sun Street, Woolwich, and a temporary
mortuary is provided in Eltham High Street. The following Table shows the use
made of the mortuaries during the year:—
