of America, imperfect as they are by contrast, are highly creditable to their intelligence.
Stone lintels were not used for these doorways, as stones three feet long-would have been required. No stones of half that length are to be seen in any of the walls. They had, however, the idea of a stone lintel, for they used them in this structure over the foot-square openings for light and air. We found a stone lintel over an opening eighteen inches wide in a cliff house on the Mancos River. This was so firmly imbedded that we found its removal impossible. They used for a lintel six round cedar cross-pieces, Fig. 42, each about four inches in diameter and now perfectly sound.
In some of these doorways we noticed a peculiar feature. On the side toward the external wall, one and sometimes two of these wooden lintels were placed, four and sometimes six inches lower than the remainder, so that on entering from the outside room into the second room, the top of the doorway rose higher as the room was entered. A necessity was experienced to save the head from bumps, and the wonder is that it did not occur
to them to raise the doorways to the height of the body. As the doorways were always open, no doors being used, it may well be that larger openings would have created stronger currents of air through the building than they wished. The ends of these lintels were hacked off by stone implements of some kind.

If this supposition be well founded, the five rooms on the ground floor, from the court back, communicated with each other by doorways. The four in the second story
