this and the rivers such as Roanoke, Tar, Neuse, Cape 

 Fear and others had not cut back to the syncline, however 

 the distance to the sea was small and the fall was com- 

 paratively great and they were g-radually cutting- away. 

 In drawing^ (Mapl) we can see how they cut this orig-inal 

 deep river up and send their streams on westward for other 

 adventures. The Great Pee Dee cut into the syncline near 

 its head and led off Brown's Creek and inverted and led 

 off Little river, then sent one of its streams on northwest 

 and at last under the name of the Yadkin it cuts into the 

 Dan River Syncline and captures a larg-e part of its head- 

 waters as we have described above. Cape Fear cuts into 

 the syncline and leads off the part we now call New Hope 

 and sends its branches on to help drain the territory 

 northwest of the syncline (note the slowness of New Hope 

 River). The Neuse cuts in and leads off a small portion 

 as does the Roanoke, and thus helps the waters to find a 

 shorter route to sea. At last this syncline leaves us this 

 remnant of its former self as evidence of what it has been 

 The inverted creeks and rivers are yet at a loss to know 

 what to do and so move along- slowly, but by and by 

 when they g-et accustomed to their new environment they 

 will pick up their spirits and move along- joyously as they 

 did of old, and later g-enerations will never know what a 

 deal of trouble they have had. Their rate of flow is prob- 

 ably even now being- accelerated by the lowering- of the 

 eastern border of the central plain.
