the opportunity. He accordingly accompanied Captain 
Macomb in an exploring expedition in the summer of 1859, 
from Santa Fé, New Mexico, to the junction of the Grand 
and Green Rivers of the Grand Colorado. This journey 
forms the subject of another masterly report by him, 
which, however, was not published for some sixteen years. 
“The shadows of the coming great Civil War were al- 
ready falling on the United States, when Newberry was at 
work on the preparation of the record of the results of his 
western journeys. ‘The storm at last burst in 1861, the 
same year in which his Colorado report was issued. Among 
the many scientific men who placed their services at the 
disposal of the North, Newberry took a foremost place. 
His medical skill and wide general scientific knowledge 
enabled him to be of great use to the army. He specially 
distinguished himseif in the organization and administra- 
tion of the hospital department. Among the reminiscences 
of his not uneventful life he had many graphic tales to tell 
of his experience during that momentous epoch in the 
history of the United States. After the close of the war in 
1865 he returned with renewed ardour to his scientific 
labours, and specially devoted his energies to the study 
of the ancient floras and fish-faunas of North America. 
Among his numerous memoirs on these subjects the two 
large monographs forming vols. xiv. and xvi. of the series 
published by the United States Geological. Survey are spe- 
cially worthy of notice. But they represent only a part of 
the enormous mass of material which he had worked over. 
‘““ Prof. Newberry early in his career saw how great was 
the aid which geology could afford in the development of 
the mineral industries of his native country, and he gave 
himself with great energy to the practical applications of 
the science. He became one of the highest authorities on 
mining matters in the country, and he was mainly instru- 
mental in the equipment of the great mining school of 
Columbia College, New York. He occupied the Chair of 
Geology in that establishment, and threw himself heart and 
soul into its duties. At last, in the midst of his work and
