logical Survey, to the New Scotland beds (lower Devonian) of New York. These newly 
recognized beds outcrop along the west bank of Tennessee River and some of its smaller 
tributaries in northeastern Tishomingo County. The New Scotland fossils were first found 
along Yellow Creek, in sees. 15 and 22, T. 1 N., R. 10 E. 
Yellow Creek rises southwest of Candler post-office, on the west side of Tishomingo 
County, flows in a general northerly direction, and empties into Tennessee River just north 
of the State line between Mississippi and Tennessee. Along its headwaters and middle 
course the stream flows over lower Cretaceous strata which overlap the older sea floor.

At Doskie post-office, on the west side of R. 10 E., Yellow Creek first begins to cut into 
the older strata, and from this place to Tennessee River the older rocks occur at intervals 
in the bed of the creek. Along its lower course, in sees. 27, 22, 15, and 14, the creek has 
channeled its bed into the hard limestone rocks, leaving perpendicular cliffs, in places more 
than 100 feet high. Above these cliffs are hills rising 150 feet higher and covered with Cre- 
taceous and Lafayette deposits.

The deep gorges of this region form a striking feature of the topography. The steepness 
of the slopes and the narrowness of the valleys indicate a rapid uplift which has caused the 
streams to erode the bottoms of their channels faster than the sides. 
Below is given a section of the strata along Yellow Creek in sec. 22, T. 1 N., R. 10 E. At 
this place the creek is at present hugging the east bank — a cliff 140 feet high. There is a 
narrow bottom on the west side of the creek, the cliff on this side receding more gently than 
on the east.
