A RHUBARB STORY
The word ‘rhubarb’ has acquired many colloquial meanings and usages, some more savoury than others, but one unlikely use of the word was as a code. It was radioed to media to inform them that Sir Edmund Hillary and his new Zealand team, driving converted Ferguson tractors, had reached the South Pole overland on 3 January 1958. They were the first to do so since Captain Robert Scott and his companions arrived at the Pole on 17 January 1912.
