It was to this paper that Whittier made his first poetical contributions anonymously, and, upon the discovery of his true name, Mr. Garrison sought him out and encouraged him in his youthful efforts.

After a brief existence of six months, the Free Press was sold and Mr. Garrison again became a journeyman printer, soon seeking employment in Boston, where, after various vicissitudes, he was employed by Rev. William Collier, a Baptist city missionary, upon The National Philanthropist, devoted to the "suppression of intemperance and kindred vices," becoming its editor in 1828. The paper had the distinction of being the first temperance journal ever printed, and among the earliest evidences of Mr. Garrison's interest in the slavery question was an editorial article by him commenting severely on the bill passed by the House of Assembly of South Carolina to forbid the teaching of reading and writing to the colored people.

To Benjamin Lundy, a Quaker, and at that time editor of the Genius of Universal Emancipation, in Baltimore—a paper devoted to the gradual abolition of slavery—belongs the honor of first attempting to awaken public sentiment on the subject. Upon his visit to Boston, August 7, 1828, he made the acquaintance of Garrison, whose eyes he opened to the iniquity of the slave system. During the same year Mr. Garrison accepted the invitation of a committee of prominent citizens of Bennington, Vt., to edit the Journal of the Times, a weekly newspaper devoted to the re-election of John Quincy Adams against Andrew Jackson. While started for campaign purposes, the Journal of the Times declared for independence of party and advocated the suppression of intemperance, the gradual emancipation of the slave, the doctrines of peace, and the so-called American system of protection for fostering native industry.

Attracted by the anti-slavery utterances of Mr. Garrison, Lundy resolved to invite him to share in the editorship of his paper, walking from Baltimore to Bennington for the purpose. His earnestness had the desired effect upon Mr. Garrison, who accepted his proffer and relinquished the Journal of the Times. Before going to Baltimore Mr. Garrison was invited to address the Congregational societies of Boston on July 4th, at the Park Street Church, and took for his theme "Dangers to the Nation." The poet John Pierpont was present and wrote a hymn for the occasion. The address was a stirring denunciation of slavery and a rebuke to the nation for its pretentious devotion to liberty. The speaker was accused by a Boston paper of slandering his country and blaspheming the Declaration of Independence.

Upon his arrival at Baltimore, Garrison, having convinced himself of the necessity of immediate and unconditional emancipation, it was agreed, inasmuch as Lundy adhered to the methods of gradual emancipation, that each should sign his own editorials.

Mr. Todd, a Newburyport merchant, having allowed his ship to be used in the inter-state slave trade between Baltimore and New Orleans, Mr. Garrison faithfully denounced in unmeasured terms his fellow-townsman, and asserted the equal wickedness of the domestic slave trade with that of the foreign traffic, which, at that time, was in the law considered piracy. Arrested, tried, and convicted of libel, although the facts were proven, Garrison was incarcerated in the Baltimore jail, April 17, 1830, in default of a fine of $50 with $50 costs. Undaunted in his captivity, he continued to write his protest against slavery and to record in verse his feelings. His famous sonnet, "The Immortal Mind," was written with pencil upon the walls of his cell. Liberated at the expiration of forty-nine days, through the generosity of Arthur Tappan, of New York, who paid his fine, Garrison visited Boston and Newburyport, endeavoring to speak in both places, but the doors of halls and churches were closed against him. At last the hall used by a society of avowed infidels, in Boston, to whom Abner Kneeland preached, was opened to Mr. Garrison for three anti-slavery lectures, and among the audience at his first lecture were Samuel J. May, Samuel E. Sewall, and A. Bronson Alcott, who then gave in their adhesion to the cause. Dr. Lyman Beecher was also present but made no sign.

On January 1, 1831, appeared the first number of The Liberator, in Boston, bearing for its motto, "Our Country is the World—Our Countrymen are Mankind." Mr. Garrison, as editor, was assisted by Isaac Knapp, a fellow-printer from Newburyport, as publisher. The paper was issued at No. 6 Merchants' Hall, at the corner of Congress and Water Streets, in the third story, the partners making their home in the printing-office. It was this office that Harrison Gray Otis, the mayor, at the request of ex-Senator Hayne, ferreted out through his police, describing it as "an obscure hole," containing the editor and a negro boy, "his only visible auxiliary," while his supporters were "a very few insignificant persons of all colors." Lowell has thus described it in a different spirit:

"In a small chamber, friendless and unseen,
Toiled o'er his types, one poor, unlearned young man;
The place was dark, unfurnitured, and mean,
Yet there the freedom of a race began."

In the initial editorial appeared the famous declaration of Mr. Garrison, "I am in earnest—I will not equivocate—I will not excuse—I will not retreat a single inch—and I will be heard." Although its circulation was meagre, the publication of The Liberator made a tremendous sensation throughout the South, bringing upon its editor abusive and threatening language, and, at the North, unpopularity and persecution. The Legislature of Georgia offered a reward of $5,000 for his arrest and conviction.
