180 THE JOURNAL OF GEOLOGY: 
of variable diameters, up to three inches. The pebbles now have 
the appearance of consolidated brownish clayey material; one 
of the pebbles contained odlitic grains similar to those of the 
general ferruginous rock in which these pebbles were imbedded. 
Three hundred feet from the road are bluish, sandy, stratified, 
non-fossiliferous layers similar to those near the top of the 
Turtle Creek section near Arment’s quarry. A little further 
down stream the crinoidal rock contained pebbles, and one of 
these was made up of the same purplish ferruginous marl which 
constitutes part of the uppermost ferruginous layer of the 
Clinton in the present section. These pebbles were probably 
obtained from the Upper Clinton, not far distant. Farther down 
stream the rock contained Platyceras (Platystoma) niagarense, 
the little Soldiers’ Home form, and Orthis elegantula. Six hun- 
dred feet from the road Illenus daytonensis, Orthis biforata, 
and Orthis elegantula were found in a whitish limestone; a single 
blue limestone pebble was seen. About 650 feet from the road 
good cross-bedding was noticed in the sandy stratified Clinton 
on the eastside of the creek.” In) one layer the stratitication® 
lines dip 25 degrees southward; immediately overlying this 
layer is one with perfectly horizontal stratification. Farther 
down stream the rock becomes more massive, with few fossils, 
but opposite the barn it contains Clathropora frondosa, and a few 
stray bluish pebbles, two to four inches in diameter, lithologically 
similar to the Clinton rock immediately above and below. Ina 
layer full of crinoid beads, together with Orthis calligramma, var. 
eu-orthis, Strophomena patenta, and Phenopora expansa, was 
found a stray small blue pebble one inch in diameter. Just 
below, opposite Wm. Haigh’s house (locality II), were found 
Illaenus ambiguus, Leptena rhomboidalis, Strophomena tenuis, 
Orthis biforata, var. daytonensis, the larger form of those with 
three plications on the median fold. Below the house in the 
creek bed were slabs containing very small pebbles, up to one 
inch in diameter; Cyclonema bilix was seen here. Below this 
rock comes the very siliceous but not cherty rock which here 
constitutes the base of the Clinton. On the opposite side of the
