It was by such means as these that the existence and the leading geographical features of the valley of Arabah were first made known to the Christian world.

ROBINSON'S VISIT TO EN-GEDI.

Edward Robinson is a distinguished American philosopher and scholar, who has devoted a great deal of attention to the geography and history of Palestine, and whose researches and explorations have perhaps accomplished more in throwing light upon the subject, than those of any other person, whether of ancient or modern times. He has enjoyed very extraordinary facilities for accomplishing his work; for, in his character, and in the circumstances in which he has been placed, there have been combined, in a very remarkable degree, all the qualifications, and all the opportunities necessary for the successful prosecution of it. Having been devoted, during the greater portion of his life, to the pursuit of philological studies, he has acquired a very accurate knowledge of the languages, as well as of the manners and customs of the East; and, being endued by nature with a temperament in which great firmness and great steadiness of purpose are combined with a certain quiet and philosophical calmness and composure, and a quick and discriminating apprehension with caution, prudence, and practical good sense, he is very eminently qualified for the work of an Oriental explorer. In the year 1838, he made an extended tour, or, rather, series of tours, in the Holy Land, a very minute and interesting report of which he afterward gave to the world. He is now, in 1852, making a second journey there; and the Christian world are looking forward, with great interest, to the result of it.

MAP OF THE DEAD SEA.

During Robinson's first tour in Palestine, he made an excursion from Jerusalem to the western shores of the Dead Sea, where he visited a spot which is marked by a small tract of fertile ground, under the cliffs on the shore, known in ancient times as En-gedi, but called by the Arabs of the present day Ain Jidy. From Jerusalem he traveled south to Hebron, and thence turning to the east, he traversed the mountains through a succession of wild and romantic passes which led him gradually toward the sea. The road conducted him at length into the desolate and rocky region called in ancient times the Wilderness of En-gedi, the place to which David retreated when pursued by the deadly hostility of Saul. It was here that the extraordinary occurrences took place that are narrated in 1 Sam. xxiv. David, in endeavoring to escape from his enemy, hid in a cave. Saul, in pursuing him, came to the same cave, and being wearied, lay down and went to sleep there. While he was asleep, David, coming out, secretly cut off the skirt of his robe, without attempting to do him any personal injury; thus showing conclusively that he bore him no ill-will. Robinson found the region full of caves, and the scenery corresponded, in all other respects, with the allusions made to it in the Scripture narrative.

CAVES OF EN-GEDI.

VIEW OF THE SEA.

As our traveler and his party journeyed on toward the sea, they found the country descending continually, and as they followed the road down the valleys and ravines through which it lay, they imagined that they had reached the level of the sea, long before they came in sight of its shores. At length, however, to their astonishment, they came suddenly out upon the brow of a mountain, from which they looked down into a deep and extended valley where the broad expanse of water lay, fifteen hundred feet below them. The surprise which they experienced at finding the sea at so much lower a level than their estimate made it, illustrates the singular accuracy of Robinson's ideas in respect to the topography of the country which he was exploring; for, if the Dead Sea had been really at the same level with the Mediterranean, as was then generally supposed to be the case, it would have presented itself to the party of travelers precisely as they had expected to find it. The unlooked for depth was owing to a very extraordinary depression of the valley, the existence and the measure of which has since been ascertained.
