While at Hanover, Professor Hale thought it his duty to resume his purpose of preaching, and was accordingly ordained Deacon by the Rt. Rev. Dr. Griswold, Bishop of the Eastern Diocese, September 28, 1828, at Woodstock, Vt.; and Priest by the same bishop, in St. Paul's, Newburyport, January 6, 1831. In taking this step he violated in no respect the charter of the college, he undertook nothing which conflicted with the duties of his professorship, he acted neither obtrusively nor illiberally; but while he occasionally preached in neighboring churches, he always, in Hanover, scrupulously observed the appointment at the village meeting-house. On Sunday nights, however, he held a service in his own house, for his own family, and the family of Dr. Oliver, and such other communicants of the Episcopal Church, and friends, as might desire to attend. Difference in sentiment on religious subjects, between Professor Hale and the Trustees of the college, and action on their part which can hardly be regarded as justifiable, led to the termination of Professor Hale's connection with the college, in 1835. In 1835, Professor Hale published two works, "A Valedictory Letter to the Trustees," and "Scriptural Illustrations of the Liturgy." In August of that year he attended the General Convention of the Protestant Episcopal Church as a delegate from the Diocese of New Hampshire. In October, 1836, the degree of D.D. was conferred upon him by Columbia College. In December, having had a severe attack of bronchitis, he sailed to St. Croix to spend the winter. His published letters under the signature of "Valetudinarius" were very pleasant to the reading public.
