VIII BIOGRAPHICAL SKETCH OF 



leans be reached Cincinnati about the end of December, 1850. 

 Upon the restoration of his health he purchased a joint inter- 

 est with his brothers in a farm in Clarke county, Indiana, 

 and in 1852 he was married. The hardships to which -he had 

 been exposed in California had rendered him subject to at- 

 tacks of rheumatism and it soon became evident that a farm- 

 er's life was to hiiri impossible. Accordingly he removed to 

 Louisville, where, after -a short time, he obtained a position as 

 assistant in a German apothecary establishment, and after a 

 year's service here he became a member of an American firm. 

 The business was much to his liking, and he soon renewed his 

 interest in botany, making the acquaintance of Leo Lesquer- 

 eux, through whose influence he directed his studies to the 

 mosses. An attack of neuralgia, which affected the heart and 

 confined him to his bed for a long time, warned him that his 

 complete recovery would be slow in the changeable climate of 

 Louisville, 'and he was advised by his physician to go South. 

 He was thus again obliged to give up all the results of four 

 years' profitable business and seek a new home. He went first 

 to Louisiana, but not finding relief there, he proceeded to 

 Vera Cruz, which he reached after a four weeks' voyage, early 

 in the year 1857. Here he became interested in a pharmaceu- 

 tical business, but on the approach of the rainy season decided 

 to remove to the highlands between Cordova and Orizaba, 

 where he was the guest of his countryman, Herr Sartorius. In 

 the autumn of 1857, in consequence of a political revolution in 

 Mexico, he returned to the United States and established him- 

 self in the drug business in Mobile, Alabama. This 

 profitable business suffered greatly during the Civil 

 War, but meanwhile Mohr was employed by the Confed- 

 erate government in manufacturing drugs from native resour- 

 ces and in testing the medicinal preparations smuggled into the 

 country from Europe. 



Towards the end of 1860, at the request of Leo Lesquereux, 

 Dr. Mohr had begun his study of the mosses of Alabama, and 

 a complete catalogue of these plants was contributed by him 

 to the "Mosses of North America," published in 1884. A col- 

 lection of the ferns of South Alabama was made at the same 

 time, and thoroughly worked up, and the results turned over 

 to Prof. Eaton for his "Ferns of North America." 



In addition to these botanical works, Dr. Mohr, undertook 

 in the interests of the "Grangers," many investigations of the 

 fertilizing value of the ashes of the various woods of Alabama, 

 and of pine straw and leaves, and of the hulls of cotton seed. 

 He also delivered many lectures and wrote many articles on 

 'subjects connected with the improvement of the exhausted
