those of Prof. Smith as a basis, the work has progressed so that 
now the herbarium contains something over 2200 species of 
flowering plants and ferns, nearly completely illustrating the entire 
State Flora. 
In 1882 or 1883, Dr. Mohr was engaged by the Louisville R. 
R. Co. to collect and report upon the products of the forest and 
fields along the line of its road within the State. The collections 
made formed a most interesting and attractive feature in the Ex- 
position held at Atlanta and at Louisville, and in 1884-85 they 
were again exhibited at New Orleans. An account of the material 
gathered was published in a pamphlet entitled «The Natural 
Resources of Alabama,” one of the few papers of its kind which 
possesses real scientific merit and in no way can mislead the 
reader or prospective settler. 
A paper on the “Resiniferous Pines of the South and the 
Manufacture of Naval Stores,” published in the Pharmaceutical Re- 
view, attracted the attention of the present chief of the Forestry 
Division of the U. S. Department of Agriculture and led to the 
engagement of Mohr to prepare for the Department a series of 
exhaustive monographs on the Southern pines of economic im- 
portance, to form a part of a report to be devoted to the biology - 
of North American timber trees. 
Mohr is possessed with a true scientific spirit and great enthu- 
siasm in his botanical work. By the amount he has accom- 
plished it is very evident that he has well improved his hours of 
leisure and doubtless stolen much time from his hours of needed 
recreation. But in this day and generation one cannot stop to 
recreate, for if he does, some more zealous worker will win the 
prize he seeks. Success from true merit seems now to depend i 
upon one’s powers of endurance. : 
Mohr has the distinction of having gone out of the beaten — 
track of systematic botanjsts and considered the plants he studied — 
from an economic aspect. He has not only increased the sum of — 
our knowledge, but he has added to our powers of direct useful- s 
ness. I would say to those who, in referring to botany, are ever 
asking the question “cud bono?” carefully read the writings a :
