ends. ‘The width of the rooms of each tier appears to have been constant 
throughout the length of the whole ruin. he dimensions given in these 
drawings are, in nearly every case, of those apartments which constitute 
the second story, as it is in those that there is the least obscuration of the 
walls. 
‘In most of the ruins the first floor is almost entirely filled up with 
débris, but when the ruins can be followed they show that this floor is gen- 
erally divided into much smaller apartments, two or three occurring some- 
times in place of each one above them. The eastern half of the ellipse, as 
above said, consists of a single continuous line of small apartments, with a 
uniform width of thirteen feet inside and an average length of twenty feet. 
By a curious coincidence the same number of rooms are in this row as in 
the outer tier of the main building. The walls of the central portion for a 
distance of about two hundred feet are in fair preservation, standing in 
places six to eight feet in height, the dividing walls showing apertures lead- 
ing from one room to another. They are built of stones uniform in size, 
averaging six by nine by three anda half inches. Mortar was used between 
the stones instead of the small plates of stone. At both ends, for a distance 
of some two hundred feet from the point of juncture with the main build- 
ing, the walls are entirely leveled, but enough remains to show the dimen- 
sions of each apartment. ‘Twenty yards from the south end of the building 
are the ruins of a great circular room fifty feet in diameter, with some por- 
tions of its interior wall in such preservation that its character is readily 
discernible.” ? 
Without the canon, upon the mesa, and about half a mile back of the 
bluff, upon the north side, are the ruins of the Pueblo Alto, constructed of 
stone on three sides of a court, like those before described. The main 
building is three hundred feet long, and one wing is two hundred feet 
measured externally from the back end of the main building, the other wing 
is one hundred and seventy feet measured the same way. This wing is but 
two rooms deep, while the main building and the other wing are each three 
rooms deep. It has six estufas, with remains of a convex wall, connecting 
the two wings, and inclosing the court. These estufas, like those in the 
ma Hayden’s Tenth Annual Report, 1878,p. 446.
