These are generally considered the finest of all beans, and should be gathered young. Shell them, lay them, in a pan of cold water, and then boil them about two hours, or till they are quite soft. Drain them well, and add to them some butter and a little pepper.
They are destroyed by the first frost, but can be kept during the winter, by gathering them on a dry day when full grown but not the least hard, and putting them in their pods into a keg. Throw some salt into the bottom of the keg, and cover it with a layer of the bean-pods; then add more salt, and then another layer of beans, till the keg is full. Press them down with a heavy weight, cover the keg closely, and keep it in a cool dry place. Before you use them, soak the pods all night in cold water; the next day shell them, and soak the beans till you are ready to boil them.
