themselves across the folds as to maintain this course as the ele- 

 vation continued and after the indurated rocks were reached. 

 May it not be that this has been the history of some of our trans- 

 verse drainage? This conception, while closely related to that of 

 antecedent streams, is different because it contemplates folding 

 that antedates the streams, while the latter contemplates .a well 

 established stream before folding takes place. 



In cases where anticlinoria emerged, not contiguous to existing 

 land areas, it seems wholly within the probabilities that many of 

 the transverse streams assumed and maintained their courses 

 across the minor folds of the limbs. It has occurred to the writer 

 that possibly this has been the history of some of the numerous 

 transverse streams in the Ouachita Mountain area of Arkansas.
