Prepare a box with a close-fitting lid. Drill a hole in the bottom of the box, then bury the box completely in ice. Half-fill the interior of the box with pieces of ice, sprinkle salt on top, and pound the ice with a wooden mallet. Spread a thin layer of straw on top and cover the entire length and width of the surface with a simple oilcloth. Freshly slaughtered domestic birds, plucked and cleaned, may be stored on this oilcloth for several days.
