Tatties are thick, loosely-woven mats, made by binding a thatch formed of short lengths of a scented grass (known as _khaskhas_) to a frame-work of bamboo, which are constructed to fit the frames of the windward doors and windows, and are kept constantly wet by a man, who goes from one to the other throwing water on them. Their efficiency depends entirely on the amount of wind, and to maintain a good current it is of course necessary that one or more of the leeward doors should be also kept open, a fact of which it is often difficult to convince the ladies, who, in their intense eagerness to shut out the heat at all costs, not unfrequently succeed in shutting it in instead. Given a fairly good breeze, and a waterman who does his work well, it is possible to produce a very marked amelioration of the temperature; and the free passage of air through the room goes far to neutralise the dangers of dampness. Of course neither these appliances, nor the thermantidote, can act except in dry heat, so that their usefulness is quite confined to the dry months of inland climates. The thermantidote, in its usual form, is a large wooden drum, within which revolves a system of fans, one of the upper quadrants of its circumference being removed and replaced by a horizontal tube, which projects through an opening in a temporary screen into the room to be cooled. The sides of the drum, through which the axle projects, are replaced, in the middle, by small tatties, and the effect of driving the fans (which work like those of a paddle boat, and not on the principle of the screw) is to draw air through these small wet mats and drive it into the room. Some of the more elaborate sort are provided with a miniature pump, which delivers water on to the mats from a trough below, the pump being driven from the same multiplying wheel as the fan. In thoroughly dry weather, it is quite possible to reduce the temperature of a room by fully ten degrees by means of these machines, but they are treacherous arrangements, especially for those who allow themselves to be tempted to sit in the full force of the current, and are responsible for a great number of chills and rheumatic twinges of all sorts, so that I believe it is better to endure the heat without them. The labour of driving them, too, is rather severe, so that relays of strong young coolies must be entertained if they are to be worked efficiently; whereas in the case of the punkah a certain knack is required, rather than mere brute strength and stupidity, so that the work is very suitable for men who are past their prime. The best punkah wallah I ever had was an old blind man, and the work seems particularly suitable for the blind, as sight is in no way required, but, in the East, these unfortunates generally prefer to resort to their traditional employment of mendicancy. The little art of pulling a punkah lies in never checking it as it swings away from you; and in making the pull just as it begins
