Before modern refrigeration, foods were kept cold by placing them on blocks of ice harvested from ponds and rivers. Farmers cut and stored ice for their farms, but also for the cities. Ice harvesting was a big business in the 19th century.
Frederick Tudor, a Boston merchant, was the first to ship ice to the West Indies. He went on to make a fortune shipping ice around the world. Even Queen Victoria purchased ice from Massachusetts in the 1840s.
