Relates how Clarkson presented a letter thanking the Emperor for his efforts in ending the slave trade and asking for further help, together with an introduction from the Duke of Gloucester, to Baroness Trudonov, someone whom the Emperor visited every evening. After a short delay he was summoned for an audience on 23 September at the Palais de Bourbon. Clarkson admits to nervousness but relates how the Emperor immediately put him at ease. Confirming his animosity towards the slave trade, something which had increased with the reading of Clarkson's book, the Tsar stated he wanted to do as much as possible to help. He had tried to outlaw it in the original treaty with France (1) but this had proved impossible. He had redoubled his efforts during the Congress of Vienna and foundations had been laid. Finally, with the help of the British minister, the French had been pressured to abandon the slave trade. Clarkson agreed that this was an achievement but English supporters were disappointed that the slave trade had not been proclaimed as piracy at the Congress of Vienna. If the allied sovereigns professed to be against robbery and murder then surely the slave trade too was illegal. Furthermore it was against justice and religion. The Emperor agreed with Clarkson's point of view but stated that unfortunately the Congress of Vienna was unable to cure all Europe's ills. It, most importantly, had to bring safety, peace and tranquility to Europe and as the slave trade could only be ended by force, there would have to be a delay whilst peace was restored. Nevertheless, it remained a goal and the fact that France had joined in abolishing it was a step in the right direction. Further discussion ensued concerning colleagues of Clarkson's from the anti slave trade movement who had previously met the Emperor, the Quaker religion and the education system in England and how it could be useful in Russia.
