=Censorship and Restraints on the Press.=--The idea of printing, unlicensed by the government and uncontrolled by the church, was, however, slow in taking form. The founders of the American colonies had never known what it was to have the free and open publication of books, pamphlets, broadsides, and newspapers. When the art of printing was first discovered, the control of publishing was vested in clerical authorities. After the establishment of the State Church in England in the reign of Elizabeth, censorship of the press became a part of royal prerogative. Printing was restricted to Oxford, Cambridge, and London; and no one could publish anything without previous approval of the official censor. When the Puritans were in power, the popular party, with a zeal which rivaled that of the crown, sought, in turn, to silence royalist and clerical writers by a vigorous censorship. After the restoration of the monarchy, control of the press was once more placed in royal hands, where it remained until 1695, when Parliament, by failing to renew the licensing act, did away entirely with the official censorship. By that time political parties were so powerful and so active and printing presses were so numerous that official review of all published matter became a sheer impossibility. In America, likewise, some troublesome questions arose in connection with freedom of the press. The Puritans of Massachusetts were no less anxious than King Charles or the Archbishop of London to shut out from the prying eyes of the people all literature "not mete for them to read"; and so they established a system of official licensing for presses, which lasted until 1755. In the other colonies where there was more diversity of opinion and publishers could set up in business with impunity, they were nevertheless constantly liable to arrest for printing anything displeasing to the colonial governments. In 1721 the editor of the _Mercury_ in Philadelphia was called before the proprietary council and ordered to apologize for a political article, and for a later offense of a similar character he was thrown into jail. A still more famous case was that of Peter Zenger, a New York publisher, who was arrested in 1735 for criticising the administration. Lawyers who ventured to defend the unlucky editor were deprived of their licenses to practice, and it became necessary to bring an attorney all the way from Philadelphia. By this time the tension of feeling was high, and the approbation of the public was forthcoming when the lawyer for the defense exclaimed to the jury that the very cause of liberty itself, not that of the poor printer, was on trial! The verdict for Zenger, when it finally came, was the signal for an outburst of popular rejoicing. Already the people of King George's province knew how precious a thing is the freedom of the press.
