informant stated that “this square hut was used by Sun as a stable 
for horses” (Libby, 1908, p. 507). 
Upon excavation the composition of mound and fill proved to be 
identical with that of the house sites, and no prepared floor was found. 
Thirty-four postmolds ranging from 6 to 12 inches in diameter were 
located. These form, in a rough way, a rectangular pattern made up 
of four rows of irregularly spaced molds. These rows are alined 
both north-south and east—west or, since the structure was not ori- 
ented to the cardinal points, with the long axis running west-north- 
west-east-southeast and the short axis at a right angle to this. This 
pattern measured, along the long axis, between 27 and 28 feet in 
length, with a width of between 20 and 21 feet. In no case is there 
a good alinement of the molds. Four molds 18 inches apart north- 
south suggest an entranceway 45 inches in width midway of the 
south line of molds. 
In addition to the larger postmolds, over 150 small molds from 
an inch to just under 2 inches in diameter were present. These 
formed a zone or band about 15 inches in width which followed the 
outer row of large posts, being found between and outside the outer 
post positions, but seldom inside that line. As was the case with 
similar molds found in the houses, remains of wood present in them 
suggest that they represent the position of willow rods thrust into 
the earth. 
Adding to the complexity of the situation encountered here was a 
group of features present in the southwest corner of the structure—a 
fireplace, a storage pit, and a feature which is believed to represent 
a borrow pit. The latter was first noted at a depth of 8 inches, where 
it showed as an area of mixed light- and dark-colored soil. It was 
irregular in outline, 16 feet in length and from 4 to 6 feet in width, 
with the long axis east-west. When cleaned of fill, it proved to have 
sides which varied from straight to rather steeply sloping and to 
have an irregularly flat bottom. The depth varied somewhat, owing 
to the irregularity of its floor, but it averaged about 24 inches below 
the floor of Feature 10. The fill throughout was of mixed light and 
dark earth with only a trace of charcoal present. No artifacts were 
found in it. 
A small cache, Feature 14, at the southwest part of the borrow pit 
preceded that feature and had been cross sectioned and partly de- 
stroyed by it. The neck measured 11 inches across, while the maxi- 
mum diameter of the body, which occurred some inches above the 
bottom, was 22 inches. The bottom was 28 inches below the present 
land surface. The sides were concave and asymmetrical (pl. 17, a), 
giving the feature a lopsided appearance in profile. It contained 
only earth of mixed color.
