 in botany, must be taken.* 



8. Field Experiments. — Testing varieties of corn, &c, in 

 fields, methods of planting, culture treating for disease, &c. 

 Special opportunities are given to advanced students to take 

 up experiments under supervision of the instructor in farm

 harrowing, draining, physical effects of different systems of 

 rotation, &c. I (5). With this subject a course in chemistry 

 or physics and one year university work are required. 



10. Special Work in Soil Physics. — Studies intended for 

 students wishing to specialise further in study of physical 

 properties of soils, e.g., determination by special methods of 

 the temperature, moisture and soluble salt- contents of various 

 soils, &c. I or II (2-5).

 with this subject : — A course in chemistry and courses 6 and 9 

 in agronomy. 



13. Investigation of the Fertility of Special Soils. — This course 

 is primarily designed to enable the student to study the fertility 

 of those special soils in which he may be peculiarly interested 

 and to become familiar with the correct principles and methods 

 of such investigations. It will be supplemented by a systematic 

 study of the work of experiment stations along the lines of the
