In making new feather beds, put half a pound of cayenne, and half a pound of black pepper in each bed; this will prevent the moths from getting into new feathers that have not been well cured. It is best to air your beds frequently, and shake them up, even if they are not slept in. It is the oil in the feathers that makes them smell bad, and when in constant use the heat of the body dries it up gradually; when beds or pillows have acquired this unpleasant smell, open them and put a few pounded cloves in each.
When new beds are covered with cases, the moth will sometimes eat through without its being discovered. Covers also prevent the air from sweetening the feathers, and when new they should never be covered unless in use. When beds are slept on, it is best to have a thick cotton sheet, or if it is cold weather, a blanket between the under sheet and the bed, and have them washed and aired occasionally.
