Every person
who keeps animals will find it a wonderful and paying protection to
them, to put against the walls one, two, three, or more layers of
newspapers during cold weather. If a person in riding finds his garments
too cool, a newspaper placed under the coat or vest, or under or over
the trousers, even if only on the side next the wind, will do a great
deal to check the outflow of heat, and keep him warm. Two or three
thicknesses of newspaper crumpled a little, and put under the coat or
overcoat, are almost as effective in keeping in warmth as an extra
garment. A slight crumpling keeps them a little separate, and makes
additional thin layers of air.
Further: Heat does not pass through films of _still_ air. Fibrous
woolens, furs, loosely woven cotton, down, and the like, contain a great
deal of air _confined_ in the meshes, and are therefore excellent
conservers of heat. Double walls of stone, brick, or wood, or even of
wall or roofing paper, double glass, double layers of anything that will
have thin layers of still air between them, prevent the escape of heat
greatly.
