which has been added his tour in the Peninsula of Mount Sinai, although the latest of all his travels in date, because it is immediately connected, by its subject, with his journey through the adjacent districts of the Holy Land. There still remain manuscripts sufficient to fill two volumes; one of these will consist of his travels in Arabia, which were confined to the Hedjaz, or Holy Land of the Musulmans, the part least accessible to Christians; the fourth volume will contain very copious remarks on the Arabs on the Desert, and particularly the Wahabys. The two principal maps annexed to the present volume have been constructed under the continued inspection of the Editor, by Mr. John Walker, junior, by whom they have been delineated and engraved. [p.iii]In the course of this process, it has been found, that our traveller's bearings by the compass are not always to be relied on. Those which were obviously incorrect, and useless for geographical purposes, have been omitted in the Journal; some instances of the same kind, which did not occur to the Editor until the sheets were printed, are noticed in the Errata, and if a few still remain, the reader is intreated not to consider them as proofs of negligence in the formation of the maps, which have been carefully constructed from Burckhardt's materials, occasionally assisted and corrected by other extant authorities. One cannot easily decide, whether the errors in our traveller's bearings are chiefly to be attributed to the variable nature of the instrument, or to the circumstances of haste and concealment under which he was often obliged to take his observations, though it is sufficiently evident that be fell into the error, not uncommon with unexperienced travellers, of multiplying bearings to an excessive degree, instead of verifying a smaller number, and measuring intermediate angles with a pocket sextant. However his mistakes may have arisen, the consequence has been, that some parts of the general map illustrative of his journeys in Syria and the Holy Land have been constructed less from his bearings than from his distances in time, combined with those of other travellers, and checked by some known points on the coast. Hence also a smaller scale has been chosen for that map than may be formed from the same materials when a few points in the interior are determined by celestial observations. In the mean time it is hoped, that the present sketch will be sufficient to enable the reader to pursue the narrative without much difficulty, especially as the part of Syria which the traveller examined with more minuteness than any other, the Haouran, is illustrated by a map upon a larger scale, which has been composed from two delineations made by him in his two journeys in that province.
