the college course and is preceded by instruction in agricultural chem- 

 istry (during the first and second years), physiological and economic 

 l)otany and vegetable pathology (during the first year), and liorticul- 

 ture (during the second 3'ear). 



In chemistry the course includes lectures and laboratory work on 

 the principles of chemistry and chemical nomenclature, organic chem- 

 istry, and the application of chemistr}^ to agriculture. The latter is 

 given during the third term of the first year and includes the following 

 topics: Ingredients of plants, organic and inorganic, essential and non- 

 essential; sources of plant food, air, and soil; nature of soil, mechan- 

 ical portion, nutritive portion, assimilal)le, and reserve plant food; 

 soil exhaustion and amelioration; barnyard manure, its sources, com- 

 position, and preservation; conmiercial fertilizers, their rational use 

 and methods of determining the needs of soils. In the second year 

 there are lectures and laboratory work on the industries related to 

 agriculture (e. g. , manufacture of sugar, starch, vinegar, and liquors); 

 and the analysis of fertilizers, feeding stuffs, dairy products, sugar 

 and sugar producing plants, fruits and vegeta])les, water, soils, oils, 

 fats, grains, etc. The lecture rooms and laboratories are thoroughly 

 equipped with apparatus and chemicals for the use of instructors and 

 students. 



The course in botanv includes elementary, physiological, and eco- 

 nomic botany, and vegetable pathology, with lectures and recitations 

 three times a week and laboratory and field work twice a week. In 

 economic botany the student receives instruction and practice in 

 handling the microscope and has the opportunity of learning much of 

 the important modern methods in technique. The main part of the 

 course in veg'etable pathology is devoted to a study of the parasitic 

 fungi most destructive to cultivated plants, and the means of their 

 prevention forms the last part of the course. Instruction in botany 

 is given in the l)otanical building which contains a large lecture room, 

 nuiseum, herbarium, three laboratorv rooms, dark room, dr^^ngroom, 

 storeroom, and offices. The lecture room will, the coming year, con- 

 tain a stereopticon furnished with electric light; a large number of 

 charts, many of them colored lithographic photographs and mounted 

 illustrative specimens are the principal appliances for daily class work. 

 In this room are placed fifteen of the more important popular journals 

 of l)otanv for the use of students. The botanical books in the univer- 

 sity library, a valuable and growing collection, are largel}" used for 

 reference in connection with the several courses. The nuiseum con- 

 tains a large amount of illustrative material, the native medicinal 

 plants and the collection of Ohio woods being very complete. The 

 State herbarium consists of between 12,000 and 15,000 sheets of Ohio 

 plants. The general herbarium is about the same size. Professor 

 Kellerman's private herbarium of 20,000 specimens, mostly parasitic
