My letter of recommendation from the Academy was afterwards read in the Government divan. It was fluently translated, sentence by sentence, into Arabic by the physician in ordinary, and the Pasha at once declared that he would be the Vokil, that is to say, the manager of affairs, for the Academy of Berlin, and promised that he would not fail to afford me the necessary assistance for my journey. How faithfully he kept his word is well known, and on that account the thanks of the Academy of Science were formally presented to him. Dyafer had been an old captain of a frigate in the stirring times of Mohammed Ali; he was a man of considerable attainments, and had already become known to me on the occasion of my first journey, when he acted as Governor of Upper Egypt. In his house were seen piles of atlases and anatomical plates; he was not wanting in a clear comprehension of, nor indeed in an actual interest in, my undertaking. He expressed his hope that my journey might accomplish its aim, and if anything of material benefit should be discovered that it might not be reserved, but freely communicated to the State. I assured him that the Royal Academy had no narrow views, and that he might be certain that although I trusted by prosecuting science to gain credit for myself, I should not overlook anything that might be honourable to him, or for the advantage of his Government. The Pasha seemed gratified by my reply, and referred me to the writers, who were to settle the various covenants of my agreement with an ivory trader, Ghattas, a Coptic Christian. The Governor-General himself had arranged the terms, and I could find little in their tenor that would be adverse to my interests. [Sidenote: PRELIMINARY COVENANTS.] Besides Ghattas, there were several other merchants in Khartoom, who possessed large settlements in the district of the Upper Nile, but he alone amongst them was not a Mahommedan; the others were, for the most part, true Osmanlis, whose reputation, with respect to slave dealing, did not stand too high. Thus the choice of the administrator fell upon the unlucky Ghattas, who, being also the richest of all, was required to become surety against any misadventure that might occur to the traveller in the interior. If he were betrayed to the cannibals, or if he were left in the lurch among savages and cut-throats, so much the better for the treasury of the Government, who would have the most legitimate reasons for proceeding to the confiscation of his estates.
