The points c c c represent projections from the groove, having holes for screwing on a wooden guide-bar, to prevent the staybar from rising out of the Fig. 105 is a section of the groove of half the proper size, in which d is the gaide,-bar of wood screwed on to the groove at c; f is the 0])ening in the bottom of the groove into which the stayliar drops. These openings may either be made at each end of the groove;^ only, for the purpose of o|)ening^ the door to the full width, or they may be made also at the inter- mediate points c c, so as to open the door to different angles, which may be convenient in hot-houses for ventilation. Fig. 106 show's a vertical pro- file of Fig. 107, i being the guide- bar, and k the door. Fig. 107, of half the proper size, shows the manner in which the guide-bar g is attached to tlie door //, the fitting nut being tight. It is to be observed that both the straight and curved grooves require a sort of cover or guide- bar all the length of the groove, placed so as to allow the hook of the stay or projjping bar to be lifted out of the hole, but not out of the groove. In the straight groove (Fig. 103, (/), a piece of wood lA bv -4 in. does very well for the cover; but in the curved groove a wrought or cast iron cover has been used, and the little tubes or projections marked c c in Fig. 104, are cast on the groove to fasten the wooden covers to securely. Gates and doors for back sheds, and for various departments con- nected with the kitchen-garden and offices of an establishment, may be most advantageously formed with staybars, instead of locks, bolts, or hooked or other fastenings. In rural architecture, the use of these stavbars is calculated to be still more extensively useful than in gar- dening. 103. Please note that these images are extracte
