Room 51 has a very well preserved fireplace in the northwestern corner and a doorway about midway in the northern wall. Its well-plastered walls show impressions of the hands and fingers of the plasterers. The eastern side of the "street"[41] is bordered by rooms 60 to 63, inclusive, which open into it. In the wall of the last room (61) to the south there is a small peephole that enabled the owners to see from within the room anyone entering the street from the court. Room 59, probably the largest angular room in Cliff Palace, is without an entrance. Its high walls form a part of the northern and eastern ends of the court and almost the whole western side of the street. A large embrasure in its southern wall had been repaired by the ancient masons before Cliff Palace was deserted. North of room 59 remains of the foundations of rooms (not numbered on the plan) were found, and it may be possible that at this point there was a small open space, without a kiva; if so, it would have been exceptional in Cliff Palace. [Footnote 41: A passage or inclosure surrounded by high walls is called kisombi by the Hopi.] Rooms 66 and 68 are round rooms, not kivas, although possibly ceremonial in character. From the roof of room 66, the walls of which are now lower than formerly, it was possible to pass on a level into one of the series of ledge rooms previously described. The floor of room 68 is exceptional in being lower than that of the cave outside, so that on entering it one descends by a step or two. Room 67 appears to have been more a passageway (_kisombi_) than a room, a step from it leading down to the level of the triangular plaza in front of the Speaker-chief's House, south of room 70. Room 70 is a milling room, with two well-preserved metatakis in one corner, each with a set of metates. In the wall above these mealing troughs there is a small window through which the women engaged in grinding corn could see the passers through the court east of this room. The opposite corner is occupied by a fireplace, and the adjacent wall is pierced by a doorway with elevated threshold, through which one passed from the milling room to the broad Speaker-chief's platform south of rooms 71 and 72.
