We shall now give some account of the travels of Mr. Banks, and the party by whom he was accompanied.[93] Having quitted the tents of the Bedouins, with whom they had sojourned for a few days, they passed into the valley of Ellasar, where they noticed some relics of antiquity, which they conjectured were of Roman origin. Here they rested with a tribe of Arabs. The next day they pursued their journey, partly over a road paved with lava, and which, by its appearance, was evidently a Roman work, and stopped that evening at Shuback, a fortress in a commanding situation; but incapable, by decay, of any effectual defence against European tactics. In the neighbourhood of this place they encountered some difficulties from the Arabs, but which, by their spirit and firmness, they overcame, and proceeded unmolested till they reached the tents of a chieftain called Eben Raschib, who took them under his protection. This encampment was situated on the edge of a precipice, from which they had a magnificent view of Mount Gebel-Nebe-Haroun, the hill of the prophet Aaron (Mount Hor); and a distant prospect of Gebel-Tour (Mount Sinai), was also pointed out to them. In the fore-ground, on the plain below, they saw the tents of the hostile Arabs, who were determined to oppose their passage to Wady Mousa, the ruins of which were also in sight. Perceiving themselves thus as it were waylaid, they sent a messenger to the chief, requesting permission to pass; but he returned for answer, that they should neither cross his lands, nor taste his water. They were in fact in the land of Edom, to the king of which Moses sent messengers from Kadish. “Let us pass,” said he, “I pray thee, through thy country: we will not pass through the fields, or through the vineyards; neither will we drink of the waters of the well: we will go by the king’s highway; we will not turn to the right hand nor to the left, until we have passed thy borders.” But Edom said unto him, “Thou shalt not pass by me, lest I come out against thee with the sword.”—Numbers xx. 17, 18. The travellers, after some captious negotiation, at last obtained permission to pass; but not to drink the waters. They did not, however, very faithfully observe this stipulation; for on reaching the borders of a clear bright sparkling rivulet, their horse would taste the cooling freshness of its waters; and Eben Raschib, their protector, insisted also that the horses should be gratified. On crossing this stream they entered on the wonders of Wady Mousa.
