a small bowlder of quartzite identical in appearance with those found 
on the surface in the vicinity which were carried as a part of the 
glacial drift from Sioux Falls in South Dakota. 
A short distance eastward from this, and about 3 feet higher, in 
the loess, was an angular fragment of stone weighing about 6 ounces, 
which looked like a metamorphosed sandstone, but effervesced with 
acid. It was highly colored, pink and red at one end and deepen- 
ing to a purplish tinge at the other. Several smaller pieces of the 
same material were found near by, also some red and yellow ochre 
which results from the decay of hematite or limonite pebbles. 
Scattered at random in the loess, at any level and at any point 
within the limits of the trench, were other ochreous deposits, some 
of them barely sufficient in amount to color the earth; angular frag- 
ments of limestone up to 6 or 7 ounces in weight; snail shells; char- 
coal; and streaks of gravel containing yellow ochre, rotten lime- 
stone, shale, quartz, quartzite, and jasper pebbles, singly or in com- 
bination. As in chamber C, some pieces of the charcoal showed 
clean-cut fractures, with no trace of wear or erosion, as if they had 
just been broken from a large fragment. With one exception the 
streaks of gravel were very limited in extent and thickness, ranging 
from a handful to perhaps half a peck. The exception was a deposit 
which was reached about 8 feet from the inner end of the trench and 
lay 4 feet above the bedrock. It extended beyond the trench in both 
directions, being 2 inches thick at the north wall and gradually 
increasing until it measured 11 inches at the south wall, under which 
it disappeared. It was composed almost entirely of limestone peb- 
bles, quite rotten, which, in conjunction with some fine fragments 
of shale, were mingled with the loess. In all these gravel deposits 
the pebbles composing them were very small, few being larger than 
a pea. 
Five pieces of bone were found in this trench. The first was 
about 3 feet above bedrock, 18 feet from the inner end of the trench. 
Tt appeared to be part of the leg bone of an animal about the size of 
an elk. There was a joint, with a portion of the shaft on each side; 
but it was in such fragmentary condition that it could not be readily 
identified. 
Three feet south of this, and 6 inches higher, was a fragment of 
bone 114 inches long and half an inch in diameter, which had been 
much gnawed by some rodent. The ends were cut off rather smoothly, 
giving it somewhat the appearance of an aboriginal bead. 
A bone as large as that from a quail’s leg was in the earth 13 
feet from the inner end of the trench and 21% feet above the bottom.
