"During King George V's Jubilee a photographer named Ferguson had permission to work from the Victoria Memorial in front of Buckingham Palace, but owing to the tremendous crowds, having permission was one thing, and getting to the scene of operations was another. He spoke to some first-aid men.

"'I simply must get to the Memorial,' he said. 'Tell me, if I were suddenly taken ill, or something, could you fellows get me through the crowd?' A great idea! The base of the Memorial had been adopted by the ambulance men as a sort of headquarters and so, after a few 'Mind your backs,' Ferguson reached his goal."
