CORROSION ON SHIPS’ HULLS
SOLUTION CLAIMED BY CANADIANS HALIFAX (Nova Scotia), Nov. 22. Canadian scientists were reported to-day to have solved one of shipping’s most expensive problems—steel hull corrosion. Mr Kenneth Barnard, chief of the corrosion section of the Defence Research Board, said that bars of magnesium were bolted to the hull in several places. The steel hull, the water, and the magnesium reacted together and produced an electric current. which prevented corrosion. Anticorrosive paint used with the magnesium governed the quantity of magnesium needed. Magnesium could do the job alone, but that would be too expensive. Ships which had been experimentally treated with magnesium 15 months ago showed no under-water corrosion, he said. Native Rioting in Nigeria.— Reuter’s Lagos correspondent says rioting and looting of European houses and shops occurred to-day at Enugu, Aba and Owerri in the Eastern Provinces as reprisals for the Enugu shooting last, week when police opened fire on striking miners.
