closed by buttons screwed to the wood- 

 work on either side of it. If it is not 

 possible to gain access to the ventilators 

 from outside, and it is necessary to fasten 

 them on the inside, the buttons must be 

 attached to the inner surface of the venti- 

 lator and turned over the surrounding 

 woodwork. When there is a row of venti- 

 lators, as shown under the wall plate in the 

 back elevation, the buttons must be 

 attached to the lower edge of the venti- 

 lator. There should be two buttons to 

 every ventilator, one near each end, and 

 not one in the centre only ; the use of two 



mediate sash bars being shown between 

 them. As there are three sash bars 

 between each pair of rafters, provision 

 is made for the reception of panes of 

 glass about 15 inches broad and the same 

 in length, but, as it has already been said, 

 the number of sash bars, which should not 

 be less than three, may be increased, 

 though it must be remembered that the 

 greater the number of sash bars the less 

 will be the space to be occupied by glass. 

 A useful hint may be given here with 

 regard to glazing. As there are no laps 

 to the panes of glass, the top edge of each

buttons tends to prevent warping. When 

 opened, the ventilator may be fixed, as 

 shown in Fig. 9, by means of a stay ofjron 

 attached to an eye screwed into the venti- 

 lator, and hanging from it when closed, 

 but propped against and sustained by a 

 small piece of iron bent at an angle and 

 screwed to the board below, as at A, a 

 depression being made in the upper part 

 of the iron to receive the end of the stay. 



A plan of the roof, also drawn to the 

 same scale, is shown in Fig. 4. In this 

 the six principal rafters running from wall 

 plate in front to wall plate at back are 

 shown at A, B, c, D, E, and F, the inter- 



pane will abut against the bottom edge of 

 the pane immediately above it. The panes 

 are to be secured from sliding downwards 

 by brads driven into the rafter or sash bar, 

 as the case may be. The usual mode of 

 doing this is shown at A in Fig. 10, and 

 under this system there must of necessity 

 be an open space of the thickness of the 

 brad between the edges of the panes. The 

 better plan is to take off the lower corners 

 of each pane, as shown at B. The brads 

 are then driven into the woodwork in the 

 space originally occupied by the corners of 

 the glass, and there is no impediment to 

 pushing up the lower pane so as to touch
