질문 내용 : Years ago, before there were refrigerators, an icehouse was a building used for storing ice. The first icehouse was in the cellars of farmhouse. Pieces of ice, mixed with snow and meadow grass, were piled in winter and kept until the following summer. Soon farmers began to build separate houses for storing ice. These icehouses had double walls with hay stuffed between to keep out anyheat. Blocks of ice were put inside the icehouse and packed with straw or sawdust.
