ceive free tuition, rent, and board; their appointment is by com- 

 petitive examination. Prof. William Trelease is the director of the 

 Missouri Botanical Garden, and has an able corps of scientific and 

 office assistants and gardeners. 



An important part of Mr. Shaw's plan was the establishment of a 

 school of botany, the head of which was to hold the George Engel- 

 mann professorship. This school is organized in connection with 

 Washington University; it is closely related to the Missouri Botan- 

 ical Garden, the directorship of which is also held by the occupant 

 of the chair. In the work of the school Professor Trelease has three 

 assistants; seventeen different courses of instruction are offered by 

 them. Under the direction of the school there are also offered at the 

 garden important courses in elementary botany for children or for 

 busy people. 



Washington University is in close touch with the Academy of 

 Science. From its faculty come some of the academy's most active 

 workers and officers. Professors Woodward (mathematics and 

 mechanics), Nipher (physics), Engler (mathematics), Pritchett (as- 

 tronomy), Trelease (botany), and Hambach (geology) have been con- 

 spicuous in its work. To the Transactions of later years they have 

 contributed numerous and important papers. At a time when the 

 academy had no other home, the doors of the university were opened 

 to it for its meetings and the housing of its library and the storing of 

 its collection. The academy is fortunate, indeed, in having been so 

 closely in sympathy with an institution of learning the interest of 

 whose teaching force more than aught else kept it active during a 

 critical period of its history. 



Among the most active members who came to recruit the force, 

 which we have seen above from Dr. Engelmann's statement had been 

 somewhat reduced by time, was that master worker in entomology, 

 Dr. Charles Valentine Riley. Born in London, England, on Sep- 

 tember 18, 1843, he was schooled at Chelsea and Bayswater, at 

 Dieppe, France, and at Bonn, Germany. In 1860 he came to this 

 country, settling upon a farm in Illinois. Removing to Chicago, 

 he began editorial work upon the Evening Journal and the Prairie 

 Farmer. Near the close of the war, May, 1864, he joined the 

 134th Illinois Volunteers. When the war ended he resumed his 

 editorial labors on the Prairie Farmer. In 1868 he was appointed 

 State Entomologist of Missouri, a position which he ably filled until 

 1877, when he was made chief of the commission appointed by the 

 United States Government to investigate the ravages and life history 

 of the Rocky Mountain locust. The greater part of the reports of 

 this commission was written by him. In 1881, when the commis- 

 sion was merged into the work of the Agricultural Department, Dr.
