THE INCORPORATORS 131 



In later life Dr. Engelmann visited the mountain region of 

 North Carolina and Tennessee, the Lake Superior region, the 

 Rocky Mountains and the Pacific Coast, seeing for the first time 

 in the native haunts many species of plants he had studied before 

 from dried specimens, and adding to the great collections already 

 made. 



He was deeply interested in the land of his adoption and 

 showed his devotion to its scientific welfare by his efforts in the 

 founding of the St. Louis Academy of Science, of which he was 

 1 6 times elected President. He also delivered courses of lectures 

 at Washington University, an institution in which he took great 

 interest. In return, many marks of appreciation were given him, 

 preeminently in the generosity of Mr. Shaw and others in collect- 

 ing and republishing all his botanical works. His entire herba- 

 rium, comprising 100,000 specimens, and his library, including 

 his notes and botanical sketches, have since been given by his son 

 to the Missouri Botanical Garden, sometimes known as the 

 Shaw Garden. 



Crushed in spirit by the death of his wife and the illness of 

 his son, in 1879 Dr. Engelmann's health was seriously impaired, 

 but accepting Professor Sargent's invitation to accompany him 

 to the forests of the Pacific Coast he gradually regained his 

 spirit of cheerfulness, and though the journey was an arduous 

 one for a man of his age he once more took up his work. In 1883 

 he revisited Europe, but soon after his return succumbed to the 

 disease that had fastened itself upon him, and died February 4, 

 1884. 



Dr. Engelmann's last publication was his meteorological work 

 the result of his observations for 47 years. 



His botanical work was very extensive, the notes made in the 

 examination of specimens amounting to 20,000 slips, constituting 

 60 quarto volumes. His studies of the cactus family, of the 

 yucca and the agave, of the American oaks and conifers, and of 

 North American vines, show marks of his indomitable energy 

 and patience. His endurance as a traveller was remarkable.
