Harvesting Winter Ice Before Refrigerators
Today, a cold drink is as close as the kitchen. A hundred and fifty years ago in the northern United States, though, cold was a crop that people harvested in winter and saved for summer.
When the ponds and rivers froze hard, crews went out onto the ice. First they marked the surface into a grid of squares. Then they cut along the lines with saws, and horses sometimes pulled a special plow to score the ice. Workers floated the loose blocks down a channel of open water to the shore, then used hooks and ramps to lift them out.
The blocks went into icehouses, which were large buildings with thick wooden walls. Workers packed them in layers and covered them with sawdust, which is a surprisingly good insulator. Ice stored this way could last through the heat of summer. Some of it was loaded onto ships and sent to faraway places, where it was a luxury.
In towns, ice was delivered by an iceman, who carried a block into your home with heavy tongs. Families kept food in an icebox, a wooden cabinet with a compartment for the ice and another for milk, butter, and meat. A card in the window told the iceman how much to leave that day. The melted water drained into a pan that had to be emptied.
Electric refrigerators slowly took over during the early 1900s, and the winter ice trade faded away.
