A moderately cool and moderately dry air in motion is the most healthful atmosphere for animal life. Ventilation.—The best system of ventilation for dairy stables is the one devised by the late Prof. F. H. King. Like other systems, it has inlets for the admission of fresh air and outlets. Fig. 9.—Showing on the left how an inlet can be placed in a wall already constructed; on the right, how an inlet can be put in a wall being built; and in the centre, an outlet shaft with two openings—one just under the ceiling and one a foot above the floor. for the removal of impure air, but it has two features which are peculiar to it. The inlet flues are bent at a right angle, and the outside opening is lower than the inner one, the purpose being to prevent the escape of air from the stable through the inlets. The outlet flues are built from the floor up and have an opening near the floor as weU as one near the ceiling, thus providing a means of drawing air not only from the upper.
