6 The American Geologist. July, 1900 
but as was his custom in illness went on with his work as 
usual. Upon completion of the last examination of the term 
he came home too ill to correct the papers, and in the course 
of the following night was attacked by a severe hemorrhage 
from the lungs and for weeks his life hung in the balance. 
With the return of spring his strength increased sufficiently 
to enable him to remove to New Mexico, where the local 
physicians told him he had a fighting chance for a few 
years. He accepted the challenge bravely and for more than 
ten years held the disease in check. During the spring of 
1894, the college dedicated the Barney Science Hall, which 
had been built largely under the stimulus of his presence in 
the faculty, but he was never permitted to work in it. 
FOURTH PERIOD. 1894-1904. 
This decade, filled with bodily pain and the worse tor- 
ture of anxiety and mental unrest, is yet one of the most 
productive periods of his life. Much of the time was spent 
in the open with covered wagon and camp kit, and with 
the return of strength scientific interests again absorbed his 
attention. Naturally in this case he again turns to geology 
and an extensive series of articles on the geology of New 
Mexico, bears testimony to the industry of these apparently 
aimless wanderings. The first scientific work done in the 
territory was a revision of his earliest important work, the 
Crustacea of Minnesota. As soon as his geological knowl- 
edge became known his services were in demand as a min- 
ing expert and during the later years of his life in the terri- 
tory he supported his family chiefly by practising this pro- 
fession as strength permitted. For four years he was the 
president of the territorial university at Albuquerque, 
though at the close of the third year it became evident that 
the strain of the executive work and confinement were too 
hard for him, and his connection during the fourth year was 
mainly of supervision and general control. During his last 
year there was an obvious failing of physical strength so 
that long field trips had to be abandoned. But the more 
quiet life gave opportunity for a thorough recasting of many 
questions and formulation of matters which had been in bis
