In 1831 Watson set up as a printer and publisher. He became a champion of the right to
free expression of opinion. Julian Hibbert, an admirer, died in January 1834 and left him a legacy, with which Watson enlarged his printing plant. He started by printing the life and works of
Tom Paine, and these volumes were followed by ''
Mirabaud's System of Nature'' and
Volney's
Ruins. Later he printed
Lord Byron's
Cain and
The Vision of Judgment,
Percy Bysshe Shelley's
Queen Mab and
The Masque of Anarchy, and Clark on the
Miracles of Christ. These book were printed, corrected, folded, and sewed by Watson himself, and issued at one shilling or less per volume. He cared for the appearance of his books, on which he lost money. In 1832 Watson was arrested, but escaped imprisonment, for organising a procession and a feast on the day the government had ordained a "general fast" on account of the
cholera epidemic. In February 1833 he was summoned at Bow Street for selling Henry Hetherington's ''
Poor Man's Guardian'', and was sentenced to six months' imprisonment at
Clerkenwell. His shop was near
Bunhill Fields; he then moved first to City Road, and in 1843 to 5 Paul's Alley. He married Eleanor Byerley, on 3 June 1834, and two months later was arrested and imprisoned for six months for having circulated Hetherington's unstamped paper, ironically entitled
The Conservative. He had come under the observation of the government as a leader of the meeting of trade unions in April of that, in favour of the action of the
Dorchester labourers. This was his last imprisonment, though he continued to issue books banned by the government. ==Chartist==
