For atime connected with the State Grange, Dr. Mohr directed 
his attention to the grasses and forage plants, with particular 
reference to those best adapted for cultivation in the coast region 
of the Gulf States. In this connection he first pointed out the 
value of Mexican clover and Lespedeza striata. His investiga- 
tions on these plants were fully published in the reports of the U. 
S. Department of Agriculture. He also communicated frequent 
articles to the local papers on this and kindred subjects. 
Many interesting waifs from foreign countries have been in- 
troduced on ship’s ballast around Mobile, and the studies Mohr 
made of these plants led to the publication in the “Botanical 
Gazette” of a paper “on the plants introduced into the Gulf 
States.” Further experiences on the same subject gained during 
the succeeding ten years furnished the theme for an article pub- 
lished last August in the « Pharmaceutical Revue” (German), on 
“Plant immigration in the Southern States through the aid of 
animals or accidently by man.” 
In 1880 Dr. Mohr was called upon by Prof. Sargent to under- 
take the investigation of the forests of the Gulf States, in regard to 
their timber resources and other products and the industries de- 
Pendent on them. This work kept him engaged in the field dur- 
ing all of one season and part of another. The results of his ob- 
Servations were reported to Prof. Sargent and published in the 
ninth volume of the Tenth Census report. While in the field 
Mohr discovered several new species and rediscovered a number 
that had long been lost sight of. His observations also furnished 
him materials for an article on forest trees of the Gulf region pub- 
lished in Vol. I of the American Journal of Forestry, and another 
on “ The Forests of the South and their Bearing upon the Inter- 
€sts of Agriculture,” which was read at the meeting of the South- 
€rn Interstate Immigration Association at Nashville. : 
In 1878 Prof. E. A, Smith, of the State Geological Survey, 
placed in Dr. Mohr’s hands the plants he had collected during his 
field work, and from that time dates Mohr’s undertaking to get 
4p an herbarium for the Survey to be placed in the museum of 
the University of Alabama. Uniting his own collections with
