While the village of the Walpi was still upon the west side of the mesa point, some of them moved around and built houses beside a spring close to the east side of the mesa. Soon after this a dispute over planting ground arose between them and the Sikyátki, whose village was also on that side of the mesa and but a short distance above them. From this time forward bad blood lay between the Sikyátki and the Walpi, who took up the quarrel of their suburb. It also happened about that time, so tradition says, more of the Coyote people came from the north, and the Pikyás nyu-mu, the young cornstalk, who were the latest of the Water people, came in from the south. The Sikyátki, having acquired their friendship, induced them to build on two mounds, on the summit of the mesa overlooking their village. They had been greatly harrassed by the young slingers and archers of Walpi, who would come across to the edge of the high cliff and assail them with impunity, but the occupation of these two mounds by friends afforded effectual protection to their village. These knolls are about 40 yards apart, and about 40 feet above the level of the mesa which is something over 400 feet above Sikyátki. Their roughly leveled summits measure 20 by 10 feet and are covered with traces of house walls; and it is evident that groups of small-roomed houses were clustered also around the sloping sides. About a hundred yards south from their dwellings the people of the mounds built for their own protection a strong wall entirely across the mesa, which at that point is contracted to about 200 feet in width, with deep vertical cliffs on either side. The base of the wall is still quite distinct, and is about 3 feet thick. But no reconciliation was ever effected between the Walpi and the Sikyátki and their allies, and in spite of their defensive wall frequent assaults were made upon the latter until they were forced to retreat. The greater number of them retired to Oraibi and the remainder to Sikyátki, and the feud was still maintained between them and the Walpi. [Illustration: Plate VII. Horn House ruin, plan.]
