 center of its woodland domain of 10,000 acres, 

 on the summit of the Cumberland Mountains, 

 2,000 feet above sea level. 



Open from March to December, the academic 

 year being divided into three terms. Students 

 from other Universities may attend the sum- 

 mer session, July 3 to September 26, in any

The University domain is being lumbered in a 

 scientific manner under the direction of the 

 Bureau of Forestry, U. S. Department of Agri- 

 culture, and an unusual opportunity is afforded 

 for the preliminary study of forestry. Sewanee 

 presents an exceptionally attractive field for 

 the study of geology, and forest and field 

 botany.
