The character of the day was peculiarly suited to enhance the impression of such scenery. Though there were no clouds, the sun was invisible: as far as we could see, beyond the Jordan, and away southward to the mountains of Moab and the cliffs of Engaddi, the whole country was covered as with the smoke of a furnace; and the furious sirocco, that threatened to topple us down the gulfs yawning on either hand, had no coolness on its wings. The horses were sure-footed, but now and then a gust would come that made them and us strain against it, to avoid being dashed against the rock on one side, or hurled off the brink on the other. The atmosphere was painfully oppressive, and by and by a dogged silence took possession of our party. After passing a lofty peak which François called Djebel Nuttar, the Mountain of Rain, we came to a large Moslem building, situated on a bleak eminence, overlooking part of the valley of the Jordan. This is the tomb called Nebbee Moussa by the Arabs, and believed by them to stand upon the spot where Moses died. We halted at the gate, but no one came to admit us, though my companion thought he saw a man's head at one of the apertures in the wall. Arab tradition here is as much at fault as Christian tradition in many other places. The true Nebo is somewhere in the chain of Pisgah; and though, probably, I saw it, and all see it who go down to the Jordan, yet "no man knoweth its place unto this day." Beyond Nebbee Moussa, we came out upon the last heights overlooking the Dead Sea, though several miles of low hills remained to be passed. The head of the sea was visible as far as the Ras-el-Feshka on the west; and the hot fountains of Callirhoë on the eastern shore. Farther than this, all was vapor and darkness. The water was a soft, deep purple hue, brightening into blue. Our road led down what seemed a vast sloping causeway from the mountains, between two ravines, walled by cliffs several hundred feet in height. It gradually flattened into a plain, covered with a white, saline incrustation, and grown with clumps of sour willow, tamarisk, and other shrubs, among which I looked in vain for the osher, or Dead Sea apple. The plants appeared as if smitten with leprosy; but there were some flowers growing almost to the margin of the sea. We reached the shore about 2 P.M. The heat by this time was most severe, and the air so dense as to occasion pains in my ears. The Dead Sea is 1,300 feet below the Mediterranean, and without doubt the lowest part of the earth's surface. I attribute the oppression I felt to this fact and to the sultriness of the day, rather than to any exhalation from the sea itself. François remarked, however, that had the wind--which by this time was veering round to the north-east--blown from the south, we could scarcely have endured it. The sea resembles a great cauldron, sunk between mountains from three to four thousand feet in height; and probably we did not experience more than a tithe of the summer heat.
