The arrangements for lighting will depend upon the aspect of the stables. and their surroundings. Stables which are built on to houses, or in proximity to them, commonly have very little choice in the matter. When it is possible to choose, the south would generally be preferred, but some authorities prefer east, and others west, and certainly there are many very good stables with a northern aspect. In arranging the windows, care should be taken that every portion of the stable is well lighted; means of cutting off the light from any part to some extent may be considered necessary, but nothing can be lost by having sufficient light to commence with, and windows are supplied now with special arrangements for ventilation, on which subject more has to be said in another place. (See chapter on Stable Architecture.) Probably the best position for stables is one in which the front of the building has an aspect between south-west and south-east; the back wall forming the heads of the stalls will thus face between north-east and north-west, and the amount and brilliance of the sunshine admitted through the windows over the mangers will be very small, and will not injuriously affect the eyesight of the horses. An ample measure of sunlight will be admitted through the windows in the opposite or front wall, and will assist in keeping the stable bright and sweet. The importance of having windows on both sides of a range of stables cannot be overestimated.
