and their variations; also drift sands and clays, particularly 

 the clays from which brick and pottery are manufactured. 



If this structure is "characteristic" of eolian deposits, it is 

 necessary to dispense with the agency of the ocean and of 

 lakes, and of alluvial deposition by river, and to let the winds 

 loose from the four corners of the earth, and to call upon them 

 to illustrate how they produced all this lamination. If the idea 

 that lamination is "characteristic" of eolian deposits be ac- 

 cepted, the cornerstone of geology, as set forth by Hutton and 

 followed to the present day, is knocked out, and there is no 

 further use for present-day geologists. The science must be 

 consigned to the limbo of myth and nonsense ; and in the fall 

 of geology will fall the collateral sciences which are based on 

 geology. 



In short, the eolian hypothesis is radically anarchistic, revo- 

 lutionary, and destructive. It is apparent that no geologist 

 can accept it without having his eyes blinded by ignorance or 

 by prejudice. Two thorough and competent researches into 

 the nature and origin of the loess have been conducted by 

 geologists of the United States Geological Survey, and they 

 both terminated in the rejection of the eolian hypothesis and 

 in the establishment of its aqueous deposition. Before this 

 conclusion is overturned, it will be necessary that a competent 

 geologist shall go thoroughly into a new investigation and 

 shall conclude by the affirmation of the eolian hypothesis. 



Now, in conclusion, having shown you that the two lines of 

 objection to the Nebraska man are based either on partial 

 knowledge or on mistaken opinions, we are at perfect liberty 

 to affirm that every method of comparison that is open to us 

 leads us to accept the evidence of Paleolithic man in America.
