3o8 The American Geologist. May. 1901. 
In September, 1871, Dr. Smith resigned the assistantship to 
take the chair of geology and mineralogy in the University of 
Alabama, with which, through his efforts, the state geologist- 
ship of that state was afterward connected. 
His successor in the assistantship of the ^Mississippi survey 
was Mr. R. H. Loughridge.* of Texas, who had for some time 
previously acted as my assistant in the chemical laboratory, and 
subsequently as instructor in general chemistry. ]\Ir. Lough- 
ridge prosecuted the chemical work of the survey during a 
part of the year 1872, and was preparing for the elaboration 
of another report covering the work done since the publication 
of the report of i860; when by an arbitrary ruling of the state 
auditor of public accounts the survey appropriation was with- 
held : and thus in the autumn of 1872 the work was peremptori- 
ly stopped. 
It has not been revived since, although so far as I am aware 
the act of i860 has never been legally rescinded. No pro- 
vision for the publication of the unpublished results has ever 
been made by the state : the records and collections of the sur- 
vey remain in the custody of the University of ^Mississippi, and 
were left by me fully labeled as to locality and time of collec- 
tion, with reference to the field notes, and to the name or desig- 
nation under which the specimens of fossils appeared in my re- 
port of i860. 
\\'hen I took charge of the Tenth Census report on cotton 
production, and at my suggestion it was determined by Super- 
intendent \\'alker that agricultural descriptions of the cotton 
states should be embodied in the report. I requested of Presi- 
dent A. P. Stewart, of the University of Mississippi, permis- 
sion to use the records of the survey in the elaboration of the 
report on that state. Permission was promptly given and the 
papers forwarded to Berkeley, Calif. : and they were used by 
me as intended, in the composition of the monograph on the ag- 
ricultural features and cotton production of Mississippi, which- 
forms part of A'olume 5 of the Census Reports for 1880. This 
paper embraces 164 quarto pages, and is accompanied by a col- 
•Mr. Loughridge subsequently received from the University of Mississippi" 
the degree of Ph. D.. and served for several years as assistant to Dr. Little 
in the geologiral survey of (ieorgia. Subsequently, acting under my direc- 
tion as special agent of ihe Kith Census, he made a reconnoissance of Texas, 
and wrote the monograj)hs on that State, Arkansas. Indian Territory. Georgia' 
and Mississippi for the reixirt on Cotton Production. Later he served on the 
Oeol. survey of Ky.. with Prof. Proctor; ,and is now connected with the- 
Agr. College of California.
