He was sent by way of Tripoli, with instructions to accompany the caravan, which takes the most direct route into the interior.

Being provided with letters from the Tripolitan ambassador, he obtained the Bey's permission, and even promises of assistance for this expedition.

At the same time he made an arrangement with two sheerefs or descendants of the Prophet, whose persons are held sacred, to join a caravan with which they intended to travel.

He proceeded with them to Mesuraba, but the Arabs there being in a state of rebellion, refused to furnish camels and guides, which, indeed, could scarcely be expected, as the Bey had declined to grant them a safe conduct through his territories.

Mr.Lucas was therefore obliged to return to Tripoli, without being able to penetrate further into the continent.
