 The Center for African Studies offers the Certificate in
African Studies for master's and doctoral students in con-
junction with disciplinary degrees. Graduate courses on
Africa or with African content are available in the Colleges
or Departments of African and Asian Languages and Litera-
tures, Agriculture, Anthropology, Art, Botany, Economics,
Education, English, Food and Resource Economics, Forest
Resources and Conservation, Geography, History, Journal-
ism and Communications, Law, Linguistics, Music, Politi-
cal Science, and Sociology.
 A description of the certificate program in African Studies
 may be found in the section Special Programs. Listings of
 courses may be found in individual departmental descrip-
 tions or may be obtained from the Director, 427 Grinter
 Hall.

 The Department of Agricultural Education and Commu-
 nication offers major work for the degrees of Master of
 Science (thesis) and Master of Agriculture (nonthesis). The
 requirements for each degree are described in the General
 Information section.
 Two curriculum options for graduate study toward either
 degree are offered.The extension option isforthose persons
 currently employed or preparing to be employed in the
 cooperative extension service, including home economics,
 agriculture, 4-H, and other related areas. The teaching
 option is for persons who are teaching agricultural educa-
 tion in the public schools and those who wish to enter the
 profession and require basic certification.
