Protection against cold is necessary because the air in the outlet flue must be kept warm, otherwise it will cease to ascend. The ceiling and walls of the stable should be air-tight and should be constructed with a view to preventing the radiation of heat as much as possible. The circulation of air through the stable results from the operation of two factors, called by Professor King aeromotive forces, namely: heat generated by the cattle, and wind. The wind drives air through the inlets on the windward side of the stable and thus increases the air pressure within the stable, as a result of which air is forced out of the stable through the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Klein, Louis Amos, 1871-.
