Horse-Chestnut Soap
It is not generally known that the horse-chestnut contains a soapy juice, not only useful in bleaching, but in washing linens and stuffs. The nuts must be peeled and ground, and the meal of twenty of them will be sufficient to mix with ten quarts of hot water, with which the clothes may be washed without soap; the clothes should then be rinsed in spring-water. The same meal being steeped in hot water, and mixed with an equal quantity of bran, will make a nutritious food for poultry.
