Valley of Hinnom. Potter’s field. Singular properties attributed to its earth. Will not act on the citizens of Rome. Gloomy character of the valley. Job’s well. Pool of Siloam. Fountain of Siloam. Periodical in its flow. Stones and columns belonging probably to the court of the ancient temple. Monuments of Zachariah and Absalom. Tomb of Jehoshaphat. Burial-place of the Jews. Valley of Jehoshaphat. View from the Mount of Olives. Plain of Jordan, and the Dead Sea. Garden of Gethsemane. Tomb of the Virgin. Tradition about her death and ascension. Another interesting excursion was along the valley of Hinnom or Gehenna, thence up the valley of Kedron, or, as I shall hereafter call it, of Jehoshaphat, (its present name,) to the summit of the Mount of Olives, and to the reputed Garden of Gethsemane. We left the city by the Jaffa gate, and began immediately to descend into the first of these valleys, which here widens considerably and then terminates. At the distance of about 500 feet from the extremity we came to a causeway, stretching quite across, and supposed to be an ancient embankment for confining waters that were discharged from an aqueduct still to be seen in the rocks above. This aqueduct may be traced for some distance on the western side of the valley where the rocks have in some places been cut with great labor to make way for it; it passes on towards Bethlehem, and I was informed, has its commencement at the Reservoirs of Solomon, about two miles beyond that city. This causeway and aqueduct probably belong to the very few remnants of the ancient Jerusalem now to be seen.
