Instead of window-sashes with glass, as in common use, I would suggest that the windows have a sash of four, or but two (if preferred) panels, to each window (two upper and two lower, or one upper and one lower--or one lower and two upper, which would make a neat and handsome window), each panel or space for panes being neatly constructed with a sieve-work, such as is now used as screens during summer season in the lower part of parlor windows. To prevent too great oxydization or too rapid decay of so delicate a structure as the wire must be, it should be made of brass, copper, or some composition which would not readily corrode. Inside or outside doors of the same material, made to close and open like the Venetian jalousies now in use in civilized countries, would be found very convenient, and add much to the comfort and health of dwellings as a sanitary measure. The frames of the panels or sashes should be constructed of maple, cherry, walnut, or mahogany, according to the means of the builder and elegance of the building--as these articles seasoned are not only more neat and durable, but, from their solidity, are less liable to warp or shrink. This would afford such a beautiful and safe protection to every dwelling against the intrusion of all and every living thing, even the smallest insect--while a full and free circulation of fresh air would be allowed--that a residence in Africa would become attractive and desirable, instead of, as now (from imagination), objectionable.
