Once worked with manuscripts in the shade of a leafy tree. Suddenly, one of the paper sheets picked up by the wind and lifted up quite high, where he was stuck among the branches. Even from the ladder before him could not reach. The memory came an old hint (sorry, I do not remember where read it) and on it I quickly built a simple jig out of a long thin poles, pegs and cord. With it from the ladder I easily reached for a sheet of paper, put him on Seva clothespins, pulled off the noose from her lever and removed the document safe and sound.
