to support the housing work of Octavia Hill (originally one of his art pupils): he bought property in Marylebone to aid her philanthropic housing scheme. But Ruskin's endeavours extended to the establishment of a shop selling pure tea in any quantity desired at 29 Paddington Street, Paddington (giving employment to two former Ruskin family servants) and crossing-sweepings to keep the area around the British Museum clean and tidy. Modest as these practical schemes were, they represented a symbolic challenge to the existing state of society. Yet his greatest practical experiments would come in his later years. In 1865–66, Ruskin became involved in the controversy surrounding Edward John Eyre's suppression of the Morant Bay rebellion. Mill formed the Jamaica Committee for the purpose of holding Governor Eyre accountable for what they perceived to be his unlawful, inhumane, and unnecessary quelling of the insurrection. In response, the Eyre Defence and Aid Fund was formed to support Eyre for having fulfilled his duty to defend order and save the white population from danger; Carlyle served as the chairman. Ruskin allied with the Defence, writing a letter which appeared in the Daily Telegraph in December 1865 ("they are for Liberty, and I am for Lordship; they are Mob's men, and I am a King's man"), donating £100 to the Fund, and giving a speech at Waterloo Place on Pall Mall in September 1866, also reported in the Telegraph. In addition to this, Ruskin "threw himself into" personal work for the Defence, "enlisting recruits, persuading waverers, combating objections." Lectures in the 1860s Ruskin lectured widely in the 1860s, giving the Rede lecture at the University of Cambridge in 1867, for example. He spoke at the British Institution on 'Modern Art', the Working Men's Institute, Camberwell on "Work" and the Royal Military Academy, Woolwich on 'War.'Ruskin's widely admired lecture, Traffic, on the relation between taste and morality, was delivered in April 1864 at Bradford Town Hall, to which he had been invited because of a local debate about the style of a new Exchange building. "I do not care about this Exchange", Ruskin told his audience, "because you don't!" These last three lectures were published in The Crown of Wild Olive (1866). The lectures that comprised Sesame and Lilies (published 1865), delivered in December 1864 at the town halls at Rusholme and Manchester, are essentially concerned with education and ideal conduct.
