Laboratory In Britain

By RONALD W. CLARK

ROAD research of direct interest and use to

colonial governments is being carried out in an increasingly large number of ways in Britain by the staff of the Road Research Laboratory at Harmondsworth, Middlesex, a few miles west of London, where work on roads, traffic problems, safety problems, and many allied matters is continually under survey.

OTHER USES

Mechanical fogging by pyrethrum spray has also proved effective in tobacco warehouses, flour mille. grain stores, ships' slaughterhouses, refuse dumps, chocolate factories, poultry sheds and fertiliser plants.

Other uses and other forms of Insecticide will bo developed at the now laboratories.

An industry whose production has risen from 15 tons in 1833 to 8,000 tons ten years later now looks forward to recovering the production loat since the war and increasing it.

The Governor of Kenya, Sir Evelyn Baring, said at the open- ing ceremony that during tha next decade world consumption was expected to rise to 13,000 tons a year. There was plenty of room, therefore, for the ex- pansion of Kenya's acreage.
