Here again is another direction in which the adoption of the system of metallic gauze protection against mosquitoes will tend to make tropical life more tolerable; for the stuff is much stronger than it looks, and would form a quite adequate protection against ordinary thieves; besides which, the gauze, for those troubled with nerves, might be easily strengthened by supplementing it with a layer of the strong wire netting used for fowl runs, &c., without making the place look like a jail, or appreciably diminishing the freedom of ventilation. It would be easy, too, by attaching to some part of the frames, inaccessible from the outside, bells hung on springs such as used to be used in houses before the adoption of the electric mechanism, to render the frames a very difficult obstacle to open without rousing the inmates, even for light-fingered gentry much more skilful than those with whom one has usually to deal. An obstruction that will keep out a mosquito may easily be modified to exclude men, and only those who have passed a hot weather in towns where it is dangerous to sleep with open doors, can appreciate what a benefit it would be to be able to dispense with the use of solid doors and sashes. Strengthened with wire netting, the gauze would form a far more formidable obstacle than any ordinary window, for a little reflection will convince anyone that even the gauze alone would be far more difficult to dispose of than the simple panes of thin glass on which we have been accustomed to rely. Usually the house may be kept open with advantage until eight or nine in the morning; but after this the thermometer begins to rise rapidly, and it becomes necessary to close up everything, while in very extreme climates it may be desirable to supplement the doors by the addition of thick, wadded curtains, but this should never be carried to the extent of making the rooms difficult to see in, for a fair amount of light is absolutely essential to health. Besides this various other expedients may be adopted, a very useful one being the sprinkling of the verandahs with a watering can as soon as the heat of the day is over, a process which may be very advantageously extended to the roof, where this is of the terraced form, always assuming that cheap labour is available. The coolness produced by the evaporation of water is also utilised by means of “tatties,” as well as in a machine known as the thermantidote.
