Burrowes reinstated manual labor and offered a single course of study.[15] Under the Burrowes system, the Agricultural Course was mandatory, and students were awarded a Bachelor of Scientific Agriculture degree after three years of study.[2] The (optional) fourth year was the Scientific Course, intended for “civil engineers, general mechanics etc.” and leading to a Bachelor of Science degree;[14] despite its name, the Scientific Course included little formal instruction in engineering, and no engineering faculty were hired.[16] A fifth year (also optional) was known as the Literary Course, which closely mirrored the traditional format of a classics education, and culminated in a Bachelor of Arts degree.[15] The agriculture-intensive curriculum had minimal impact on enrollment: the 1870-71 academic year saw 59 enrolled students, 52 of which were in their first or second year of study.[16] The fact that agriculture was insufficient to support an entire college was experienced by many land-grant institutions, and the challenge of incorporating a non-agriculture curriculum reform was exacerbated by the general indifference of the Pennsylvania legislature toward land-grant institutions as a whole.[16] It was felt that, as the school was an instrument of the commonwealth, it should be supported via regular state appropriations; however, critique for curriculum reform was often received from Harrisburg, but not the money necessary to enact it.[16] The financial burden from Allen's administration continued, and Burrowes died of exposure (as a consequence of a mountain outing with students) in February 1871 without seeing his three-course format implemented.[15]
