This staircase, like that last mentioned, is supported by the half of a triangular arch, precisely like the other already mentioned. The whole front was ornamented with sculpture, and the ornaments best preserved are over the doorway of the centre apartment, which, being underneath the staircase, cannot be exhibited in the engraving. The principal building, it will be seen, has pillars in two of its doorways. At this place, for the first time, we met with pillars used legitimately, according to the rules of known architecture, as a support, and they added greatly to the interest which the other novelties here disclosed to us presented. These pillars, however, were but six feet high, rude and unpolished, with square blocks of stone for capitals and pedestals. They wanted the architectural majesty and grandeur which in other styles is always connected with the presence of pillars, but they were not out of proportion, and, in fact, were adapted to the lowness of the building. The lintels over the doors are of stone. [Engraving 43: Building (Casa no. 3)] Leaving this building, and crossing an overgrown and wooded plain, at the distance of about three hundred and fifty yards we reach the terrace of Casa No. 3. The platform of this terrace, too, had been planted with corn, and was easily cleared. The plate opposite represents the front of the edifice, which, when we first came upon it, was so beautifully shrouded by trees that it was painful to be obliged to disturb them, and we spared every branch that did not obstruct the view. While Mr. Catherwood was making his drawing, rain came on, and, as he might not be able to get his camera lucida in position again, he continued his work, with the protection of an India-rubber cloak and an Indian holding an umbrella over the stand. The rain was of that sudden and violent character often met with in tropical climates, and in a few minutes flooded the whole ground. The washing of the water from the upper terrace appears in the engraving. This building is called by the Indians la Casa de la Justicia. It is one hundred and thirteen feet long. There are five apartments, each twenty feet long and nine wide, and all perfectly plain. The front is plain, except the pillars in the wall between the doorways indicated in the engraving; and above, in front, at the end, and on the back are rows of small pillars, forming a simple and not inelegant ornament.
