small transom. The opening was being reduced in size by means of 
adobe masonry at the time the draw-

double transom over a lintel com-

Inasonry separating the transom 
into two distinct openings rests 
upon the lintel of the doorway and 
supports a roof-beam; this is shown 
in the figure. Other examples of 
transoms may be seen in connection 
with many of the illustrations of :

lintel is made, extending across the opening from 2 to 6 inches below 
the main lintel, and fixed into the masonry in a position to serve as a 
curtain pole. Originally this pole undoubtedly served as a means of 
suspension for the blanket or skin rug used in closing the opening, just
