"PRINCIPLES OF OIL ACCUMULATION": REPLY 373 



To say that the time has not yet come to abandon previous 

 ideas concerning oil migration up the slope of a sand is only helping 

 to cover a weak link in the anticlinal theory, and passing the 

 responsibihty of correcting questionable points before precedent 

 has estabHshed a dangerous stone in the progress of the new science. 

 Oil geology is now undergoing a crisis in its history, so the time is 

 ripe for each follower in the science to face the facts squarely and 

 to strive with an unbiased mind to reach the correct solution of oil 

 accumulation phenomena. One of the world's greatest industries 

 demands, by its expenditures of niilKons, that those offering scien- 

 tific interpretation endeavor to gain the clearest and most logical 

 principles based upon the maximum of details. 



The discussion of this article has been most welcome.
