We were just ready to start; the supplies were all on board, the donkeys and horses were shipped, when an officer arrived from the Divan, to demand from me the poll tax that Moosa Pasha, the Governor-general, had recently levied upon the inhabitants; and to inform me, that in the event of my refusing to pay the said tax for each of my men, amounting to one month's wages per head, he should detain my boats. I ordered my captain to hoist the British flag upon each of the three boats, and sent my compliments to the Government official, telling him that I was neither a Turkish subject nor a trader, but an English explorer; that I was not responsible for the tax, and that if any Turkish official should board my boat, under the British flag, I should take the liberty of throwing him overboard. This announcement appeared so practical, that the official hurriedly departed, while I marched my men on board, and ordered the boatmen to get ready to start. Just at that moment, a Government vessel, by the merest chance, came swiftly down the river under sail, and in the clumsiest manner crashed right into us. The oars being lashed in their places on my boat, ready to start, were broken to pieces by the other vessel, which, fouling another of my boats just below, became fixed.

The insolence of Turkish Government officials is beyond description--my oars were smashed, and this insult was the reparation; so, stepping quickly on board, and brushing a few fellows on one side, I was obliged to come to a physical explanation with the captain, which terminated in a delivery of the oars. The bank of the river was thronged with people, many were mere idlers attracted by the bustle of the start, and others, the friends and relatives of my people, who had come to say a last good-bye, with many women, to raise the Arab cry of parting. Among others, was a tall, debauched-looking fellow, excessively drunk and noisy, who, quarrelling with a woman who attempted to restrain him, insisted upon addressing a little boy named Osman, declaring that he should not accompany me unless he gave him a dollar to get some drink. Osman was a sharp Arab boy of twelve years old, whom I had engaged as one of the tent servants, and the drunken Arab was his father, who wished to extort some cash from his son before he parted; but the boy Osman showed his filial affection in a most touching manner,
