have indicated, a little to the west of north. The pyramid is 137 feet 
in height and 511 feet on a line of the base on the north and south 
sides, and 426 on the east and west base lines, covering exactly five 
acres. On the west face of the pyramid is a large opening disclosing 
a horizontal passage. This leads in for a distance of about forty feet, 
where it terminates in a well about fifteen feet in depth. The object 
of this chamber is left to conjecture. Lying about two hundred feet 
from the west side is a sculptured rock of porphyry, which once served 
as the sacrificial stone, while near the north side lies a sculptured 
image also of porphyry which once stood upon the summit of the tem- 
ple. These valuable relics of the Toltecs were rolled from their 
position and mutilated by order of Bishop Zumar-ra-ga, who made 
such havoc of the Aztec and Toltec records, and spent his ener- 
gies in trying to destroy every trace of the heathen races, believing 
that the natives would the more readily embrace the christian faith. 
Coming down the stairway on the southern face of the pyramid, you 
come into the the Camina de la Muerta, or way of death, which termi- 
nates on this face. This way is laid in cement and is as smooth and 
clean asa floor. It is about a hundred feet in width and between 
three and four thousand feet in length. The paved way is laid in levels 
and any change of level is marked by a descent of steps which are of 
the full width of the road. As one can imagine, a stairway a hundred 
feet in width is a striking architectural feature. On either side of this 
pavement are imposing structures from twenty to sixty feet in height, 
some in pyramidal form and some are built square with cornices. The 
pavement for its entire length is lined on both sides with these build- 
ings which were used as tombs. The southern end of the pavement 
terminates in a large square structure of solid masonry, which has a 
heavy cornice. Looking from this point the architectural effect is impos- 
ing in the extreme. The broad pavement with the stairway of full 
width is sunken deep between the rows of tombs and terminates far 
away in the stairway of the pyramid. This wonderful pavement, with 
the tombs and terminal temples, is one of the grandest archeological 
studies on the continent. 
Some two miles away from these remains we came upon several 
large buildings. One of them was 60 feet in length by 28 in width. 
The walls were standing about four feet high, with a doorway in the 
face only. Two rows of columns were left standing about the same 
height as the outer walls. I visited this place first in 1874 and again in 
1875. I made a third visit to the place ten years later. During my 
first visit I was astonished at the number of “finds.” Ina search of an
