174 GEOLOGICAL SURVEY 
At Royal’s Ferry, on the left bank of the river, the marl is uncovered on the road leading to the 
water; it is yellow, somewhat sandy, and very rich in organic remains. I traced it in the low bluff, 
above and below the ferry, a distance of 300 yards, varying in height from five to eight feet. 
During a very hurried examination, I collected, immediately at the ferry, about thirty species of 
fossils, and among them, Lucina Jamaicensis and Chama arcinella. 
Harris’s Landing is the highest point on the river, at which I saw Pliocene marl ; the bed is thin 
and overlaid by laminated beds of clay. On the opposite side of the river a white rich marl is 
exposed, just above the water line. 
These are the most important localities that I examined on the river. hat there are many 
others, no one can doubt, for these are all natural exposures, and a careful search, such as any one 
may make, will bring others, equally important, to light. Between the Marion road and the river 
there are several lime-sinks—certain indications of the presence of marl below the surface—but the 
country is flat and low, and the overlying beds are rarely cut through by the streams.
