Cutting Winter Ice for Summer Drinks
Before homes had refrigerators, how did people keep food cold in the summer? In the 1800s, in places with snowy winters, the answer was ice cut from frozen lakes and ponds.
When the ice grew thick enough, workers headed out with saws and horses. They marked the ice in squares and sawed it into big blocks. Using long poles, they floated the blocks to the shore and slid them up a ramp into a building called an icehouse.
Inside the icehouse, the blocks were stacked in rows with sawdust packed in between. Sawdust works like a blanket, because it slows the heat from getting in. Thick walls helped too. Stored this way, ice could last all through the warm months.
In summer, a delivery worker brought blocks of ice to homes and shops in a wagon. Families set a block in an icebox, a wooden cabinet with a space for ice. As the ice melted, it kept the food cool, and a pan caught the drips. Some ice was even shipped by boat to far-off cities. Later, machines learned to make ice, and electric refrigerators took the place of the old iceboxes.
