24 Pa. Stat. § 2542
It shall be the duty of the board of trustees as soon and as often as the exigencies of the institution shall require, in addition to the principal, to employ such other professors, teachers or tutors, as shall be qualified to impart to pupils under their charge a knowledge of the English language, grammar, geography, history, mathematics, chemistry and such other branches of the natural and exact sciences as will conduce to the proper education of a farmer; the pupils shall themselves, at such proper times and seasons as shall be prescribed by the board of trustees, perform all the labor necessary in the cultivation of the farm, and shall thus be instructed and taught all things necessary to be known by a farmer, it being the design and intention of this act to establish an institution in which youth may be so educated as to fit them for the occupation of a farmer.
