HORN HOUSE. The Horn House is so called because tradition connects this village with some of the people of the Horn phratry of the Hopituh or Tusayan. The ruin is situated on a projecting point of the mesa that forms the western flank of Jeditoh Valley, not far from where the Holbrook road to Keam’s Canyon ascends the brink of the mesa. The village is almost completely demolished, no fragment of standing wall remaining in place. Its general plan and distribution are quite clearly indicated by the usual low ridges of fallen masonry partly covered by drifted sand. There is but little loose stone scattered about, the sand having filled in all the smaller irregularities. It will be seen from the plan, Pl. VII, that the village has been built close to the edge of the mesa, following to some extent the irregularities of its outline. The mesa ruin at this point, however, is not very high, the more abrupt portion having a height of 20 or 30 feet. Near the north end of the village the ground slopes very sharply toward the east and is rather thickly covered with the small stones of fallen masonry, though but faint vestiges of rooms remain. In plan the ruin is quite elongated, following the direction of the mesa. The houses were quite irregularly disposed, particularly in the northern portion of the ruin. But here the indications are too vague to determine whether the houses were originally built about one long court or about two or more smaller ones. The south end of the pueblo, however, still shows a well defined court bounded on all sides by clearly traceable rooms. At the extreme south end of the ruin the houses have very irregular outlines, a result of their adaptation to the topography, as may be seen in the illustration. [Illustration: Plate XX. Plan of Walpi.] The plan shows the position of a small group of cottonwood trees, just below the edge of the mesa and nearly opposite the center of the village. These trees indicate the proximity of water, and mark the probable site of the spring that furnished this village with at least part of its water supply. There are many fragments of pottery on this spot, but they are not so abundant as at Awatubi. Two partly excavated rooms were seen at this ruin, the work of some earlier visitors who hoped to discover ethnologic or other treasure. These afforded no special information, as the character of the masonry exposed differed in no respect from that seen at other of the Tusayan ruins. No traces of adobe construction or suggestions of foreign influence were seen at this ruin. SMALL RUIN BETWEEN HORN HOUSE AND BAT HOUSE. On a prolongation of the mesa occupied by the Horn House, midway between it and another ruined pueblo known as the Bat House, occur the remains of a small and compact cluster of houses (Fig. 3). It is situated on the very mesa edge, here about 40 feet high, at the head of a small canyon which opens into the Jeditoh Valley, a quarter of a mile below.
