on the top of the ridge piece. In the autumn, when the 
sashes are put on, the opposing sashes come together at 
these points, and wood screws (screw bolts) fasten the hoop 
iron strips to the styles (wooden bars forming the sides of the 
sash). Hence, upon completion of the work, each venti- 
lating sash is held in place at the upper end by two strips of 
hoop iron (instead of hinges). This thin iron is flexible, and 
is in all respects as good as a hinge, and does not rust out 
like a hinge. ‘The lower end of the sash is lifted exactly as 
in the case where hinges are used. The ends of the styles, 
at the top, are beveled, so as to make the opposing sashes fit 
closely together.

on the framework of the house is shown in the summer-time 
picture of one of Louis Reichner’s houses, at Belmont avenue 
and Ford road, Philadelphia.
