LIFE OF JAMES DWIGHT DANA 



see why I should have thought that I had first presented 

 the. idea. My cruise over the oceans in 1838 to 1842 

 brought such subjects before me, and gave me opinions 

 that otherwise I might never have reached. I wish much 

 to know when you made your first publication of the 

 view, that I may give you credit for it. I shall probably 

 say something on the subject when I notice Wallace in 

 the Journal" 



DANA TO GUYOT 



" GREAT BARRINGTON, July 2, 1884. 



41 You see by my date above that I am already in the 

 country, seeking the rest and quiet that Commencement 

 week with its excesses makes very necessary. It was a 

 time of special interest to us, as it ended Arnold's college 

 course, and was the fiftieth anniversary of my graduation. 

 With him it was made doubly memorable by the recep- 

 tion of your most beautiful gift a gift that touched 

 us all most deeply, and was a surprise and delight to 

 him. . . . 



" My class meeting a gathering of nineteen, between 

 sixty-eight and seventy-six in age passed off very pleas- 

 antly, but of course without the hilarity of recent gradu- 

 ates. Though the end was to each in manifest view, we 

 were a cheerful group; and why not, for we were all 

 Christians. 



" I get my vacation rest by excursions among the 

 rocks, and this summer Berkshire will again be my field 

 of study. It is a delightful region, with everything in 

 the scenery and people to make geologizing a recrea- 

 tion.
