an air of greater importance, “while the Dúbbah is your friend and conductor; for I will myself,” said he, “go on in advance, and if I find the tracks of hostile horses about the wells, woe be to the rascals upon their backs!” We had been trying very hard, during this important communication, to keep as solemn a face as we could, but the concluding bravado of old Shekh Mahommed rendered all our best efforts unavailing; and we fairly laughed out, in spite of ourselves, to the great discomposure of our valiant protector. The old Shekh had often talked of similar interruptions which were to be expected upon the road, but we could not, at first, upon the present occasion, perceive his actual motive for introducing the subject so formally and circumstantially. The next day, however, we found there had been a competition between the Dúbbah and our Mesurata camel-drivers, who were desirous of accompanying us to Bengazi, and whom for their good conduct on most occasions we should have been very willing to retain in our service. At any rate, we wished the competition to continue till we had concluded our bargain with one of the parties, as we knew that we should otherwise be exposed to the extortion which is almost invariably practised by an Arab when he knows there is no alternative but to accept his proposals. Both parties, however, knew that we must, under any circumstances, continue our route; and that it would not be possible for us to do so without camels, whether we advanced or returned. For this reason we had never made any positive promise that we would take the Dúbbah’s camels at Boosaida, and we had never given any notice to the camel-drivers of Mesurata that we should not continue them if they wished to proceed with us farther.
