large number of shorter publications issued by the United States Geo- 
logical Survey, State Surveys of Arkansas and Tennessee, and many 
others published in magazines or elsewhere. Considering the large 
amount of administrative work in the University of Arkansas that fell 
to his lot, this is a rather remarkable showing of scientific results for a 
teaching professor occupying practically the whole bench of geology. 
Mr. Purdue was a member of the American Institute of Mining 
Engineers, the Indiana Academy of Sciences, the National Geographic 
Society, and the Seismological Society of America. He was a Fellow 
of the American Association for the Advancement of Science, the Geo- 
logical Society of America, and the Geological Society of London. He 
often attended the meetings of State Geologists, of the Conservation 
Congress, and of the Southern Commercial Congress. While at the 
University of Arkansas he was made a teacher member of the Kappa 
Alpha fraternity. In 1907 he was elected to the Stanford chapter of 
Sigma Xi. The commencement following his resignation as Professor 
of Geology at the University of Arkansas that institution conferred on 
him the degree of LL.D. There was no recognition that he prized more 
highly than his election, in 1911, to the Council of the Geological Society 
of America. He was President of the Tennessee Academy of Sciences 
at the time of his death and was already considering possible subjects 
for the next annual address. 
As a citizen, Mr. Purdue was always public-spirited, entering in 
large degree into the life and activities of the place of his home and 
of the State at large. In Nashville, besides his interest in the Com- 
mercial Club, he was active in other civic and social clubs, including 
the Rotary, Freolac, Tennessee Historical Society, Nashville Engineer- 
ing Society, Reynolds Lodge, Knights of Pythias, Phoenix Lodge, Free 
and Accepted Masons, and was a generous subscriber to the work of 
various organizations. His home, with two boys now of college age, 
was always a place for real Southern hospitality, for Purdue had a 
large sense of humor and a live personal interest in the welfare of all his 
friends, and a wife whose intellectual attainments and personal charms 
not only added to the welcome of the home but were a constant inspira- 
tion to the man. 
There is appended a list of titles of papers and addresses, including 
several prepared but not yet published.
