Other items of foodstuffs which received special attention were imported marzipan, prawns,
and desiccated coconut. 1,688 samples of tea were submitted to the Public Analyst: this compares
with 3,571 samples in 1959, the satisfactory standard of which justified a reduction of
sampling in 1960.
Clean Air Act, 1956.
Shipowners, masters of vessels and engine-room personnel, owners of tugs, and the Port of
London Authority have all contributed appreciably to assist in reducing smoke from vessels to
a minimum. Previously the Port Health Authority had concentrated mainly on infringements of the
Regulations in respect of black smoke only, but during 1960 lesser shades of dark smoke
received similar attention. Legal proceedings were taken in respect of five offences.
Transport of Refuse by Lighters
Although the sheeting of loaded lighters has improved considerably since the difficulties of
the trade were discussed with the industry and the Port Health Authority bye-laws amended,
there is still the need for constant supervision. Legal proceedings were taken in four instances.
Canal Boats
175 inspections of canal boats were made during the year, 73 defects being found on 46
boats.
Visitors and Students
Qualified medical men and public health inspectors from abroad and from local authorities
and technical colleges in this country continue to visit the port for varying periods to obtain
theoretical and practical instruction in port health work. The year 1960 was a particularly active
one in this respect.
Launches
The four launches continue to give regular and efficient service, and credit for this must be
given to the crews employed who are tireless in their efforts to maintain the condition and
appearance of the vessels at a high level. The 'Howard Deighton' is now nearing the end of her
career with the Authority and a new boarding cutter, designed to meet the present and envisaged
requirements, is now being built. The Hulk 'Hygeia' has given entire satisfaction since the refit
in 1959.
Finally, I wish to record my appreciation of the collaboration and assistance rendered by
Her Majesty's Customs, the Pilots, the Port of London Authority, the Shipping Federation, the
staffs of Shipping Companies and Merchants, the staffs of the Central Public Health Laboratory
and the 'Dreadnought' Seamen's Hospital, the Public Analyst, the Emergency Bed Service, the
South-East Metropolitan Regional Hospital Board, the Dartford Hospital Management Committee,
and all those who have so generously and willingly helped me in every aspect of port health
work throughout the year.
I have the honour to be, Gentlemen,
Your obedient Servant,
J. GREENWOOD WILSON.
