lower rooms. Between rooms 8 and 11, location 8, was a typical 
doorway, 36 cm. in height by 34 cm. in width, and having a round 
top. (Pl. 8.) Jambs, top and bottom, were nicely plastered, as 
was usually the case in most places. A few doorways were found 
with the stone sill in situ. 
The doorway between rooms 23 and 24, location 3, had a wooden 
lintel; originally there must have been a row of rods set across the 
top so as to form this lintel, with adobe nodules placed above it to 
carry up the wall. (Pl. 8.) Only one of the rods was in situ and 
it was so badly rotted that no estimate of the diameter could be 
made, nor were there any indications as to the number of rods used, 
as the wall on the north side had fallen away so that only a shell 
remained without any stick markings. This was the only case of a 
wooden lintel that we found. 
Between rooms 27 and 28, location 3, was a typical oblong square 
doorway. (PI.7.) This is the type that was most frequently met 
with. Between rooms 7 and 8, location 3, was one of the oval-top 
type. The stone slab used to cover the opening stood at the base 
of the wall alongside of it. 
We found no traces of casing or recessed jambs such as are foand 
at Mesa Verde and other ruins, where stone slabs had been used for 
doors. I think the slab was ete on the slightly projecting sill and 
leaned against the wall at the top of the opening. Nothing suggest- 
ing wooden slab doors or hangings of hide, cotton, or other fabrics 
over the openings was found. 
Not a single case occurred where the jambs, lintels, and sill were 
all made of stone, as sometimes occurs on the Jemez Plateau. 
In the middle of the south wall of room 20, location 10, was a 
sealed doorway. A metate had been set up in the opening and mud 
plastered all around it. (Pl. 8.) Im many cases we found door- 
ways sealed with chunks of adobe much larger than the nodules in 
the walls. 
FLoors 
The floors were composed of a mixture of ash, grease, very fine 
charcoal, water, and adobe. This mixture was applied in a semi- 
liquid oer which, when partially dry, was beaten down so as to 
form a solid mass, sine: is easily distinguishable from anything else. 
After the composite was properly laid down it was polished with a 
flat stone, many of which wefound. There is no doubt that addi- 
tional washes of this mixture were put on as the necessity arose, as 
we found floors with different colored layers showing, in the cross 
section, where the floor had lost its polish and other coats of wash 
had been applied. An average thickness of the black polished floor 
surface in the rooms excavated is 6mm. The thickest floor surface 
encountered was 22 mm. and showed many coats of wash. (Pl. 9.)
