Brewster, obliged like the rest to seek some occupation for a livelihood, at first engaged in teaching the English language to students in the university. Being familiar with the Latin, the language of the schools and the court at that day, he was eminently fitted for the task. He afterward opened a publishing house, being assisted with capital by Thomas Brewer, an Englishman, who was a member of the university. Of course, under the circumstances, he engaged in the publication of books in the advocacy of Church reform, destined for circulation in England. In 1616 he published a commentary in Latin on the Proverbs of Solomon, by Cartwright, with a preface by Polyander. There are three copies of this work in Plymouth, one owned by the First Church, one by William Hedge, Esq., and another by the Pilgrim Society. In 1618 he published _A Confutation of the Remish Translation of the New Testament_, also by Cartwright, without, however, the name of the publisher on the title-page. When the Remish (Romish) translation appeared, Secretary Walsingham requested Cartwright to undertake its refutation, and sent him one hundred pounds to aid him in his work. Archbishop Whitgift, learning what Cartwright was doing, prohibited his proceeding further. Cartwright at first desisted, but afterward perfected the work as far as the fifteenth chapter of Revelation. The manuscript lay many years neglected, until at last, defaced and worm-eaten, it came into the hands of Brewster, and was given by him to the world. A copy also of this work is in the library of the Pilgrim Society. A treatise in Latin on the true and genuine religion, and Ames’s reply to Grevinchovius on the Arminian controversy, also in Latin, followed, and other works, which fully occupied his time until his departure for New England. The appearance of these books did not fail to alarm King James, who gave orders to Sir Dudley Carleton, English Ambassador at the Hague, to prevent their further publication, and if possible to secure the arrest of the publishers. Brewster was sought for, but at that time was in England engaged in negotiations with the Virginia Company, and could not be found. Brewer was arrested, but being a member of the university, was, under its charter, exempted from the liability of being sent to England. He consented, however, to go of his own accord, the university making it a condition of his going that he should be treated as a free man and not a prisoner, that he should be well used, and after his examination be suffered to return without charge to himself. He was afterward discharged, and the abandonment by Brewster of his business in anticipation of his departure prevented further trouble.
