Houses of this type are well suited to climates usually blessed with a good breeze, and in which the heat during the day does not reach such a degree as to necessitate shutting it out, and are specially adapted to places where, from scarcity of labour, there is a difficulty about the pulling of punkahs. When, however, the midday heat reaches into the nineties, such a plan of building becomes unsuitable, and it is necessary to adopt the thick-walled type of house, with comparatively few floor level openings; the object being to keep imprisoned the cooler night air, so that the interior may never approach the maximum shade temperature of the day. It is obvious that the adoption of this principle quite precludes all proper ventilation, and that unless the rooms are exceptionally large and lofty it must be positively unhealthy. At the same time, heat beyond a certain degree induces such severe nervous and physical prostration that the adoption of this course is almost unavoidable during the worst hours of the day in such climates as the Punjab; but the shorter the period the better, and as the same reasons that render the house cooler than the outer air in the day, make it hotter at night; it is always well to compensate for the lack of ventilation during the day by sleeping absolutely in the open at night. [Illustration: FIG. 4.--Rough ground plan of an European Bungalow in Persia.] Too often, not only the air, but the light is shut out, a course of action which is as pernicious as it is futile, for unless the sun be shining directly into the room its temperature will be in no way raised by admitting an ample amount of light. There can be no doubt that this baneful practice of keeping children shut up in darkened rooms is one of the principal causes of the blanched and enfeebled little ones so often met with in India; for they suffer promptly from deprivation of light, though they are wonderfully tolerant of heat, and if unchecked by their anxious mothers, will follow their own wholesome instincts, and be found romping and tumbling about with the servants and orderlies in the verandah, at temperatures that make their parents devote anxious consideration to the question of crossing a room. [Illustration: FIG. 5.--Sketch of bungalow with terraced roof, of a type very common in the Punjab and United Provinces in India. Speaking generally, this bungalow is well planned. Its faults are that the verandah is too low-pitched, leaving a needlessly large proportion of the external walls exposed to the full power of the sun. The dormer or ventilating windows also are too low down, as they leave several feet of confined “dead” air at the top of the rooms. They should have been placed close up to the cornice.]
