FEWKES] WORK OF EXCAVATION AND REPAIR 41 
as in the case of Compound A, but the removal of the earth was 
more tedious, it being necessary to carry the material a greater 
distance. The difficulties of work in Compound B were somewhat 
increased by the presence of successive floors, one below another. 
This condition was found on the tops of the mounds and in the 
plazas, necessitating careful excavation by hand. 
The outlines of the many fragile-walled houses supported by rows 
of posts could readily be followed, but as the supports were much 
decayed, provision for the preservation of evidence of the existence 
of these rooms, which otherwise under the torrential summer rains 
would soon be destroyed, had to be made. ‘To indicate the positions 
of the upright supports of these walls, new posts of cottonwood were 
inserted in the old holes, most of which were found to be filled with 
fine yellow sand and the decayed remains of the former supports. 
The fireplaces in the middle of the floors of these fragile-walled 
rooms, opposite the entrances, were protected with wooden covers. 
The floors were smoothly made and evidently had been tramped 
down. 
The bases of all the walls exposed by the excavation work were 
strengthened with cement, so that they might resist longer the action 
of the water. 
CLAN-HOUSE 1 
The excavation and repair of Clan-house 1 were satisfactorily 
completed. No walls were visible when work began, but two low 
ash-colored mounds were traceable among the mesquite trees, indicat- 
ing the site of a large building; there was no means of knowing, how- 
ever, the shape or size of the rooms later brought to light. As work 
progressed on the larger, or more westerly, of these mounds, the west 
wail of a large building was the first to be traced. Having determined 
the position of the southwest corner, the removal of earth from the 
south and west walls was easily accomplished. The earth was hauled 
some distance from the walls by means of scrapers and later provi- 
sion was made for diverting the surface drainage on these two sides. 
The outside of the east and north walls was similarly treated. Tem- 
porary roadways left about midway in the west wall were utilized for 
hauling the material removed from the central room. The plaza east 
of this room was filled originally with earth to the level of the top of 
the compound walls; the removal of this to the level of the floors 
of the central room and plaza required about a month. The bases 
of the walls were treated with cement and shallow drains parallel 
with them were dug to carry away the surplus water. 
The presence of unusually large accumulations of earth in the 
rooms of Clan-house 1 can not be accounted for wholly by the falling
