effect on health and roads were the subject of many questions at the conference of the West Riding Urban District Councils' Association. at Scarborough. last week. The answers, so far as health was con:. cerned. were reassuring.
Dr, A. J. Dalzell-Ward, Tnedical director of the Central Council for Health Education, agreed that fumes were a grave nuisance, but no harm to health had been revealed. Men working on the maintenance of engines in London Transport garages, where fumes poured out continuously, showed no significant increase in lung cancer or other respiratory illnesses when compared with men working in London as a whole.
Bad maintenance, he said, was indicated by the emission of foul black smoke from oil-engined vehicles, and this was a nuisance rather than something with a specific effect upon health.
The breaking up of road surfaces was caused by fumes, agreed Dr. DalzellWard, but was caused by the high concentration of fumes at road level and the high temperature. Lungs were never subjected to such concentration, and they would not accept the large particles of carbon in the smoke.
'Hie chairman, Mr. H. Haigh (Sowerby Bridge) said that the matter would be referred to the national association.
BIGGER BEDFORD 7-TONNERS
ANEW version of the Bedford forwardcontrol 7-tonner. capable of accommodating an l8-ft.-long body, was announced on Wednesday. It is similar in specification to the present 13-ft.-wheelbase 7-tonner which remains in production, except that on the new model flitch plates are not available as an extra.
The wheelbase is 14 ft., which increases the back-of-cab-to-end-of-frame measurement by 2 ft. The model is available with the same three power units offered in the previous 7-tonners. In each case the extra length increases the kerb weight, for the chassis alone, by 70 lb or, by 250 lb., if a drop-sided truck body is fitted. The longer chassis costs flO more than the standard versions and the increase in body length adds a further flO to the cost.
