“ He stayed in Abyssinia for two years, gaining knowledge which enabled him subsequently to present a perfect picture of Abyssinian life. On the 14th of November 1770 he reached the long-sought source of the Blue Nile. Though admitting that the White Nile was the larger stream, Bruce claimed that the Blue Nile was the Nile of the ancients and that he was thus the discoverer of its source. The claim, however, was not well founded (see Nile: Story of Exploration) . ”

“ Throughout his journeyings in Barbary and the Levant, Bruce made careful drawings of the many ruins he examined. He also acquired a sufficient knowledge of medicine to enable him to pass in the East as a physician.
In June 1768 he arrived at Alexandria, having resolved to endeavour to discover the source of the Nile, which he believed to rise in Abyssinia. At Cairo he gained the support of the Mameluke ruler, Ali Bey; after visiting Thebes he crossed the desert to Kosseir, where he embarked in the dress of a Turkish sailor. ”

“ In 1758 his father’s death placed him in possession of the estate of Kinnaird. On the outbreak of war with Spain in 1762 he submitted to the British government a plan for an attack on Ferrol. His suggestion was not adopted, but it led to his selection by the 2nd earl of Halifax for the post of British consul at Algiers, with a commission to study the ancient ruins in that country, in which interest had been excited by the descriptions sent home by Thomas Shaw [1] (1694–1751) , consular chaplain at Algiers, 1719–1731. ”
