components, and the Lower Helilerberg limestone, which, up to this time, 

 had never been identified in the State, was found to cover a far wider area 

 than any other single element of the group. A geological map of the 

 State was completed, and detailed examination of counties was in progress 

 in all the districts into which the Slate was divided. 



This was, perhaps. Dr. Newberry's happiest year in connection with 

 the Ohio Survey. Before the end of 1870, a difference of view as to the 

 prosecution of the work had developed within the organization of the 

 Survey, and legislative inquiries followed such differences. In all these 

 questions and controversies Dr. Newberry always carried his side when 

 he was on the ground. If he had had only the work of the Survey on his 

 hands, he could have had his own way with it, but as he sometimes 

 reminded the Legislature, " the absent are always wrong." 



In spite of such interruptions he followed out his original plans in 

 their essential features. The two volumes of palaeontology of the 

 Survey were his special pride, and remain as honorable monuments of 

 his scientific acumen and his learning. His treatment of the Devonian 

 fishes of Ohio constitutes the opening chapter of one of the most 

 remarkable revelations of paleontology. 



My relations to Dr. Newberry during these years were most cordial 

 and intimate. He was prompt and generous in his recognition of the 

 good work of any subordinate. His criticisms were kindly but pene- 

 trating and helpful. I have never known a man whose conceptions 

 were clearer and higher as to the value of the increase of knowledge, 

 per se, irrespective of the obtrusion of personality into the questions 

 involved, "The truths that we discover, the advances that we make," 

 he would say, "are certain to remain, to become a part of the estab- 

 lished knowledge of men, but the worker himself cannot long escape 

 oblivion, at the best." 



Dr. Newberry labored faithfully in his own field, and made splendid 

 contributions to science. The work, we are sure, will remain as a perma- 

 nent addition to knowledge; the memory of the worker, the genial friend, 

 the inspiring companion, the broad-minded student of nature, we hereby 

 pledge each other, to keep fresh and green during the hours that remain 

 of our own little day. 



I am, my dear Professor, 



Faithfulty yours,
