If the rolling screen is not used, the casement can be covered with top-hung outside screens, side-hung, double-door style, or single from one side or stationary on the outside, if the window opens inside. When possible the casement screen should be hung on pivot hinges to permit ease of detaching for storage, and, as we said before, to leave the window without the marring of the hinge there or removed. However, frequently in the case of the unusually large screen the use of a little strap hinge is sometimes necessary to carry the extra weight. In marble window casing the hinge of course is an impossibility. A couple of side levers on either side of the screen for releasing the pivots when the screens are to be taken off for the winter make the matter of removal as easy as “falling off a log.” The top hinge screen on the outside of the window which pushes out from the inside has to be hung very securely and the bolts and pivots and handles and adjusters have to be made to perfection. The adjuster for pushing this window out or open must be a pleasure to use or else this type of screen will be a curse. There is an adjuster now on the market that is put on the window in such a way that the screen can be opened or closed without opening the inside of the window. A double insurance against inroads of bugs while opening the window to adjust screen! Put up to “stay put” stationary screens are fastened with bolts which are removed when necessary to store. WOODEN FRAMES The story of the wooden frame is about the same as the metal, only that the wood frame can’t rust, but can wear out if not seasoned and kiln dried and given all the care in manufacture that long life in woods necessitates. Here, too, the corner construction must be perfect, must be able to bear the weight of the screen and take out the jars. The frame must be rigid, light and strong. The wire cloth must be so fastened at every point that there is no sag or bagginess in the broadest window. Now all this is possible in the best wood frame screens and with good workmanship. Every one thought for a long time that the metal screen could not incorporate their good points. Don’t be fooled by some one saying that the wood screen cannot be made “fool proof,” for it can and is. Here again every maker has his own device for catching the metal cloth; here again the metal cloth must be rustless; here again the metal work and hardware must be rustless; the screen must make easy manipulation possible. The screen door question, too, is rallied round with the same provisos of manufacture as metal and wood screens. There are the two leaf door and the one leaf.
