99 JOURNAL OF THE 
eroded edges of granites and crystalline schists. With- 
ina few miles above the junction of the Haw and Deep 
rivers both of these streams pass from the slates of the 
Piedmont plateau region to and across a narrow strip of 
Jura-trias sandstone, which latter is made up of mater- 
ials far more easily eroded than the slates, and as might 
be expected there are shoals on both streams at this 
junction. The rivers join within this sandstone area, 
and for a few miles below the junction the Cape Fear is 
a Sluggish stream. 
ON THE YADKIN-—-PEE DEE RIVER. 
On the Yadkin-Pee Dee river a condition of things 
exists somewhat similar to that on the Cape Fear just 
mentioned. The course of the Yadkin river as it crosses 
the slates, for some 15 miles above its junction with the 
Uharie, is briefly described further on. Below its junc- 
tion with the Uharie the river flows for a distance of 
some 20 miles in a southerly course obliquely across and 
in places paralleling the upturned edges of the argilla- 
ceous slates. In this distance there are only two promi- 
nent shoals, but neither of great importance as compared 
with those at the narrows above. These are Swift 
Island shoal, 42 to 444 miles above the state line, and 
Gunsmith shoal, 13 miles further up the river. Further 
down, the river flows easterly asa somewhat sluggish 
stream across a few miles of red sandstone rocks, simi- 
lar to those crossed by the Cape Fear at the junction of 
its two tributary streams. It then enters the coastal 
plain region, near where it is joined by Little river and 
follows a southerly course via. Cheraw, 35 miles below. 
Throughout this distance there is a succession of shoals 
due to the fact that the river crosses the upturned and 
irregularly eroded edges of alternate beds of slaty and 
granitic rocks.
