In the summer of 1835, a mob of excited citizens broke open the post- office at Charleston, South Carolina, and burnt in the street such papers and pamphlets as they judged to be "incendiary;" in other words, such as advocated the application of the democratic principle to the condition of the slaves of the South. These papers were addressed, not to the slave, but to the master. They contained nothing which had not been said and written by Southern men themselves, the Pinkneys, Jeffersons, Henrys, and Martins, of Maryland and Virginia. The example set at Charleston did not lack imitators. Every petty postmaster south of Mason and Dixon's line became ex officio a censor of the press. The Postmaster-General, writing to his subordinate at Charleston, after stating that the post-office department had "no legal right to exclude newspapers from the mail, or prohibit their carriage or delivery, on account of their character or tendency, real or supposed," declared that he would, nevertheless, give no aid, directly or indirectly, in circulating publications of an incendiary or inflammatory character; and assured the perjured functionary, who had violated his oath of office, that, while he could not sanction, he would not condemn his conduct. Against this virtual encouragement of a flagrant infringement of a constitutional right, this licensing of thousands of petty government officials to sit in their mail offices--to use the figure of Milton--cross-legged, like so many envious Junos, in judgment upon the daily offspring of the press, taking counsel of passion, prejudice, and popular excitement as to what was "incendiary" or "inflammatory," the Evening Post spoke in tones of manly protest.
