388 CLAYS AND CLAY INDUSTRY. 



some greensand is exposed along the banks of a mill pond. It is 

 not far distant from the Kinkora branch of the Pennsylvania R. R. 

 At locality 118, one-half mile west of Columbus, a black, micaceous 

 clay is exposed to a depth of 6 feet. Its weathered portion, how- 

 ever, is yellowish in color. A sample, burned at cone 05, had an 

 air and fire shrinkage of 6.6 per cent, and absorption, 30.47 per 

 cent., showing that the bricklet was very porous. A mile farther 

 west (Loc. 119) another outcrop' of a chocolate-colored clay was 

 noted along the road. The clay was smooth and plastic and was 

 exposed for 4 feet. Both of these outcrops belong to Clay Marl 

 II, and at both a great thickness of clay could undoubtedly be 

 found. 



Bustleton. — Four feet of mottled, weathered clay outcrops along 

 a brook a mile northeast of Bustleton, on the road to Three Tuns, 

 It belongs to Clay Marl I, and is apparently a good brick clay. 



Jacksonville. — Numerous exposures of Clay Marl II occur 

 along Assiscunk creek, north of Jacksonville, and at some locali- 

 ties, as at 122, a mottled, yellowish clay, probably a local deposit 

 along the stream, was noted. 



Pensauken creek. — The exposures of the Clay Marls on Pen- 

 sauken creek, near Maple Shade, have already been described. At 

 locality 154, i J /\. miles north of Maple Shade, the contact of Clay- 

 Marl I, a marly, sandy clay, upon the underlying Raritan sand, is 

 shown. The locality is not promising from an economic stand- 

 point, but it is interesting, since it shows the sharp contact of the 

 two- formations. 



Cohmisey Clays. 



Mount Misery. — Clays belonging to' the Cohansey formation, 

 are known to occur in Burlington county, near Mount Misery, 

 one mile south oi Hanover station, where they have been worked 

 at intervals. The pits were near the old Browns Mills road and 

 one-half a mile northwest of Mount Misery. At the village, also, 

 a brick clay was formerly dug in the south bank of the stream, 

 but it is very sandy. 



South Park. — A large tract at South Park (Loc. 298), 2}^ 

 miles northwest of Harris station, on the Jersey Southern R. R.,
