second house is immediately adjoinitig, and is surrounded by an inde- 

 pendent wall, that on the lower side of the ridge being still twelve feet 

 in height. The length of the enclosure is 4.69 metres, and the width 



2.68 metres ; full sized scrub-oak and sage-brush are growing in it. The 

 stumps of two cedar posts remain, one live, the other eight inches in 

 diameter. The third house adjoins No. 2, but is surrounded by a dis- 

 tinct wall, except at the back or side next the precipice, where a ledge of 

 rock, completes the enclosure. The latter is 4.02 metres long ; it con- 

 tains a scrub-oak of three inches diameter, which is an average size for 

 the tree. 



Beyond these ruins is an interval of sixty-nine metres, where the sum- 

 mit of the rock is narrow and smooth, and the dip on the west side 55°. 

 The walls of an oval building folio 77 (fig. 1), which enclose a space of 



4.69 metres. They are two to two and a-half feet in thickness and stand 

 eight feet high on the western side ; the eastern wall stands on the sheer 

 edge of the precipice. A building adjoins, with the dividing wall com- 

 mon to the preceding house. Its east and west walls stand on parallel 

 ledges of the sandstone strata, whose strike does not exactly coincide 

 with the axis of the hog-back. Diameter of this enclosure 5.37 metres. 

 A space of 15.4 metres follows with precipices on both sides when we 

 reach house No. 6. The eastern wall stands five feet high on the sum- 

 mit of the precipice, from which a stone might be dropped to the ground 

 perhaps three hundred and fifty feet below, only eight feet of the western 

 wall remained at the time of my examination. The enclosure is 6.04 

 metres long, and not quite so wide, and is divided transversely by a wall 

 which cuts oS less than one-third the length of the apartment. In one 

 of the opposite corners of the larger room is the stump of a cedar post 

 five inches in diameter. This house can only be reached by climbing 

 over narrow ledges and steep faces of rock. House No. 7, follows 

 an interval of 42.30 inetres. Its foundation wall encloses an irregular 

 square space 4.70 metres long and 3.69 metres wide ; it is eleven feet 

 high on the western side, and very regularly built, and well preserved ; 

 on the east side it is eight feet high, and is interrupted by a doorway of 

 regular form. From this a narrow fissure offers a precai'ious hold for 

 descent for a considerable distance down the face of the precipice, but 

 whether passable to the bottom I could not ascertain. 



The crest of the ridge is without houses for 52.34 metres further ; 

 then a building follows whose enclosed space is an irregular circle of 



4.70 metres diameter. A transverse summit-ledge forms its southern 

 wall, but the remaining portion is remarkably massive, measuring three 

 feet in thickness. Its western wall is twelve feet high , and contains many 

 huge stones, which four or five men could not lift unaided by machinery. 



Several scrub-oaks, of tliree inches in diameter grow in this chamber, 

 and stumps of the cedar posts that supported the roof remain. Here 

 follows a row of ten similar ruined houses, measuring from 3.35 to 6.24 

 metres in length. Of these, No. 13 is remarkable for containing 

 a scrub-oak of thirteen inches in diameter, the largest that I have
