The expression "tireless cooking" is not strictly applicable to the process to be here described, but is sufficiently near it to make it applicable as a short title. For many years the " hay box" has been in regular use, and has proved of great utility for certain kinds of cooking. While not of particular value in many lines claimed by its over enthusiastic advocates, it is, nevertheless, worthy of careful consideration in every household, and this is especially true on hot summer days when a morning fire can be used to produce a hot meal to be served up in the evening.
