which was a layer mixed with sand, shown by the black space. 
Stone implements were discovered in this layer. They were but few 
in number and very rude, exclusively of argillite, and palaeolithic 
in type. Greatest depth of layer, 2 feet, inches. Least depth, 
observed, 1 foot, 4 inches. No implements of bone were found. 
I should here state that the continual infiltration of water from 
a spring on the surface soil near by, made it very difficult to ex- 
amine the layers ; much of the material contained in them being 
so decomposed that it was impossible to save it. Here and there, 
however, by using great care the remains of different animals were 
secured ; and, on a following page, I give a list of these identified 
by the late Dr. Shivers of Naaman’s Creek. 
Layer T . — This was of reddish gravel intermingled with decom- 
posed schist, cinders, and broken bones of animals. Fragments of 
a human skull were found at the spot marked on the sketch in this 
layer. A fragment of a human rib was also discovered. The frag- 
ments of the skull are covered, here and there, by dendritic incrus- 
tations. Rudely chipped points and other implements, all of argil- 
lite, were found in this layer. Depth of layer 13 to 18 inches. 
Layer D . — Composed of reddish-yellow clay. Depth, 2 feet, 3 
inches. No implements. 
Layer M . — In this layer were numerous implements of argillite 
and some of bone, intermingled with rude implements of quartzite 
and jasper and fragments of rude pottery with charcoal. Greatest 
depth, 1 foot, 1^ inches. Least depth, 3 inches. 
Layer R . — Yellow clay. Greatest depth, 2 feet, li inches ; least 
depth, 8 inches. No implements. 
Layer W . — This contained chipped implements, those made of. 
jasper and quartzite predominating over those of argillite. Im- 
plements of bone and ornaments of stone, bone and shell. In the 
lower part of this layer were fragments of rude pottery. In the up- 
per portion of the layer were potsherds decidedly superior in deco- 
ration and technique to those from the lower portion. Geological 
composition of this layer, yellow clay loam. Greatest depth, 3 feet, 
4 inches. Least depth observed, 21 inches. 
Layer L . — This consists of leaf mold, 7 inches thick, converted 
into swamp muck by decomposing action of water from springs. 1 
No implements. 
*The position of the spring inferred to was about ten feet to the right of the outcrop 
G (see plan, p. 145), and being somewhat elevated above the shelter a portion of its wa- 
ters flowed into the depression between the outcrops P and G.
