MORGAN. DESCRIPTION OF MASONRY. . 57 
be referred to a higher stage of civilization and refinement than is discover- 
able in the works of Mexicans or Pueblos of the present day. Indeed, so 
beautifully diminutive and true are the details of the structure as to cause 
it at a little distance to have all the appearance of a magnificent piece of 
mosaic work. 
‘‘In the outer face of the buildings there are no signs of mortar, the 
intervals between the beds being chinked with stones of the minutest thin- 
ness. The filling and backing are done in rubble masonry, the mortar 
presenting no indications of the presence of lime. The thickness of the 
main wall at base is within an inch or two of three feet; higher up, it is less, 
diminishing every story by retreating jogs on the inside, from bottom to top. 
Its elevation at its present highest point is between twenty-five and thirty 
feet, the series of floor beams indicating that there must have been originally 
three stories. The ground plan, including the court, in exterior develop- 
ment is about 403 feet. On the ground-floor, exclusive of the out-buildings, 
are fifty-four apartments, some of them as small as five feet square, and the 
largest about twelve by six feet. These rooms communicate with each 
other by very small doors, some of them as contracted as two and a half by 
two and a half feet; and in the case of the inner suite, the doors communi- 
cating with the interior court are as small as three and a half by two feet. 
The principal rooms, or those most in use, were, on account of their having 
large doors and windows, most probably those of the second story. The 
system of flooring seems to have been large transverse unhewn beams, six 
inches in diameter, laid transversely from wall to wall, and then a number 
of smaller ones, about three inches in diameter, laid longitudinally upon 
them. What was placed upon these does not appear, but most probably it 
was brush, bark, or slabs, covered with a layer of mud-mortar. The beams 
show no signs of the saw or axe; on the contrary, they appear to have been 
hacked off by means of some very imperfect instrument. On the west face 
of the structure, the windows, which are only in the second story, are three 
feet two inches by two feet two inches. On the north side they are only 
in the second and third stories, and are as small as fourteen by fourteen 
inches. At different points about the premises were three circular apart- 
ments sunk in the ground, the walls being of masonry. These apartments
