172 TRANSACTIONS OF THE [Mar. 27 
components, and the Lower Helderberg 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 State 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 paleontology 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, ‘‘Thetruths 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. 
Iam, my dear Professor, 
Faithfulty yours,
