prominent; and we made up our minds that these lintels were of wood. We had no authority for this. It is not suggested either by Del Rio or Captain Dupaix, and perhaps we should not have ventured the conclusion but for the wooden lintel which we had seen over the doorway at Ocosingo; and by what we saw afterward in Yucatan, we were confirmed, beyond all doubt, in our opinion. I do not conceive, however, that this gives any conclusive data in regard to the age of the buildings. The wood, if such as we saw in the other places, would be very lasting; its decay must have been extremely slow, and centuries may have elapsed since it perished altogether.
The building has two parallel corridors running lengthwise on all four of its sides. In front of these corridors are about nine feet wide, (Plate 48,) and extend the whole length of the building upward of 200 feet. In the long wall that divides them there is but one door, which is opposite the principal door of entrance, and has a corresponding one on the other side, leading to a courtyard in the rear. The floors are of cement, as hard as the best seen in the remains of Roman baths and cisterns. The walls are about ten feet high, plastered, and on each side of the principal entrance ornamented with medallions, of which the borders only remain; these, perhaps, contained the busts of the royal family. The separating-wall had apertures of about a foot, probably intended for purposes of ventilation. Some were of this form +, and some of this T, which have been called the Greek Cross and the Egyptian Tau, and made the subject of much learned speculation.
The ceiling of each corridor was in this form⁊. The builders were evidently ignorant of the principles of the arch, and the support was made by stones lapping over as they rose, as at Ocosingo, and among the Cyclopean remains in Greece and Italy. Along the top was a layer of flat stone, and the sides, being plastered, presented a flat surface. The long unbroken corridors in front of the palace were probably intended for lords and gentlemen in waiting; or, perhaps, in that beautiful position, which, before the forest grew up, must have commanded an extended view of a cultivated and inhabited plain, the king himself sat in it to receive the reports of his officers, and to administer justice. Under our dominion Juan occupied the front corridor as a kitchen, and the other was our sleeping apartment.
From the centre door of this corridor a range of stone steps, thirty feet long, leads to a rectangular courtyard, eighty feet long by seventy broad. On each side of the steps are grim and gigantic figures, carved on stone in basso-relievo, nine or ten feet high, and in a position slightly inclined backward from the end of the steps to the floor of the corridor. The engraving, No. 49, represents this side of the court-
