MEMORIAL ADDRESSES BEFORE THE SCIEN- 

 TIFIC SOCIETIES OF WASHINGTON* 

 JAMES DWIGHT DANA. 



I HAVE a profound reverence and love 

 for the memory of Dana. Nearly a quar- 

 ter of a century ago, when I had returned 

 from an exploring expedition in the pla- 

 teau province, I prepared an article for 

 the Journal of Science setting forth some 

 of the characteristics of that land, espe- 

 cially the great blocks into which it is 

 broken by faults and the tilting and wear- 

 ing of these blocks into plateaus. In that 

 article I characterized the faults, as such 

 were then unknown. On sending the arti- 

 cle Dana wrote me a long letter which led 

 to a correspondence and an interview. The 

 geology of arid lands is more easily read 

 than that of humid lands, and Dana re- 

 monstrated with me about my conclusions, 

 not deeming it possible to discover such 

 faulting on an exploring expedition, es- 

 pecially as it is on a gigantic scale. 

 Finally I visited him in New Haven, tak- 

 ing with me a series of sections, a body of 

 notes and many' photographs, all of which 

 we discussed somewhat in detail. From 

 that time Dana became my adviser and
