DETAILED DESCEIPTION OF COURSES IN AGRONOMY. 



ALABAMA POLYTECHNIC INSTITUTE. 



In the Alabama Polytechnic Institute five four-.year courses lead to 

 the degree of bachelor of science. These courses are cheniistry and 

 agriculture, civil engineering, electrical and mechanical engineering, 

 g^eneral course, and pharmacy. Elementary agriculture (breeds of live 

 stock) is taught in the third term of the freshman year in all courses. 

 Agriculture is an elective throughout the sophomore year of the
