A busy Harbourmaster was often frustrated by field trips of school children arriving in the afternoons to watch ships coming into port. Busloads of enthusiastic and rambunctious students would invade the moorages and boardwalks every day creating messes, disrupting the work of the stevedores and generally wreaking havoc.
He remembered an old proverb and devised a method to stop the field trips. He went to the schools and passed out certain fruit. The field trips stopped.
The proverb he remembered was "An apple a day keeps the dock tours away."
