Mr Walter James Thompson has London's most peculiar job - every day from eight in the morning ultil six thirty at night Mr Thompson sits in a little cabin on the roof of the power station at Bankside watching the sky for clouds and fog - the reason is that fog and clouds cause an enormous extra load to be thrown on the generators of the power station owing to extra lights and without warning there might be a breakdown - Mr Thompson has been at his job for 12 years - he lost an arm in an air raid during the was - photo shows Mr Walter James Thompson watching the sky from his lofty perch January 28th 1935
