could see from our terrace the lofty Castillo and the top of the temple on the east wall of the Ball Court.
The Castillo is a stately building, even in its ruined condition, and must have been magnificent in the days of its splendour. The great pyramidal foundation, 195 feet square at its base, is ascended on each side by a grand stairway of over ninety steps, with a low, broad, stone edging. The sides of the foundation were terraced and faced with stone, and were probably at one time ornamented with mural paintings. The temple which stands on this magnificent foundation faces N.N.E., and is not set quite true to the lines of the base of the pyramid. At the foot of the northern stairway are two huge serpents' heads, and the porch of the temple is supported by two serpent columns. Both doorways and interior columns are rich in carving, but the design and execution of the ornament is poor in comparison with that found in some of the other temples.
Westward of the Castillo is a complicated group of colonnades and temples which had not been previously surveyed. We were able only to make a surface survey, and such excavations as were necessary to ascertain the ground-plan of the temples; there still remains in this direction a splendid field for investigation by the next explorer.
To the north-west of the Castillo stands the Great Ball Court, which is perhaps the most interesting building at Chichén. Two parallel walls, 272 feet long and 27 feet high, standing 119 feet apart, form the side boundaries of the court, which is open at either end. A terrace, 5 feet high and 10 feet broad, projects from the base of the walls as is shown in the section. From the middle of each wall, 3 feet from the top, projected a great stone ring, measuring 4 feet in diameter and 18 inches in aperture, carved from
