wide, but usually they are much smaller and very irregular in outline. 
For windows pieces are selected that approximately fit against each 
other, and thin, flat strips of wood are fixed in a vertical position in the 
openings to serve as supports for the irregular fragments of selenite, 
which could not be retained in place without some such provision. The 
use of window openings at the bases of walls probably suggested this 
use of vertical sticks as a support to slabs of selenite, as in this position 
they would be particularly useful, the windows being generally arranged 
on a slope, as shown in Fig. 89. Similar glazing is also employed in 
the related, obliquely pierced openings of Zuni, to be described later.

Selenite, in all probability, was not used in pre-Spanish times. No 
examples have as yet been met with among ruins in the region where 
this material is found and now used. Throughout the south and east 
portion of the ancient pueblo region, explored by Mr. A. F. Bandelier, 
where many of the remains were in a very good state of preservation, 
no cases of the use of this substance were seen. Fig. 90 illustrates a 
typical selenite window.

In Zuni some of the kivas are provided with small external windows 
framed with slabs of stone. Itis likely that the kivas would for a long 
time perpetuate methods and practices that had been superseded in the 
construction of dwellings. The use of stone jambs, however, would 
necessarily be limited to openings of small size, as such use for large 
openings was beyond the mechanical skill of the pueblo builders.
