It struck me at the time that I visited the plain of Jordan and the Dead Sea, that the descent from Jerusalem to them was greater than that from Jerusalem to the Mediterranean. It is now a pretty well ascertained fact that the Dead Sea is lower than the Mediterranean; and as the water of the latter sea is above thirty feet lower than the Red Sea, it must follow that the Jordan never flowed through the El Ghor into the Elanetic Gulf. Count Barteau, who has just returned from a visit to Petra Acaba, and an examination of the district between the south end of the Dead Sea and Acaba, states that a high district crosses the El Ghor, and causes the water to run north and south from it. Dr. Wilson and Lord Lindsay gave me substantially the same information. From some experiments it is estimated that the level of the Dead Sea is several hundred feet lower than those of the Mediterranean. If a passage then were made connecting the Red with the Dead Sea, the waters would flow into it, so as to cover all the plain of the Jordan, and even raise the level of the waters of Lake Tiberias. The question will naturally be asked, where did the waters of the Jordan flow to, before the destruction of the cities of the plain? what outlet did they find? The more common opinion heretofore has been, that before the overthrow of those cities there was no lake on the south end of the plain of Jordan. The Bible does not, however, say so, but rather intimates the reverse. The Salt Sea is mentioned before the account of the overthrow of Sodom and Gomorrah. It seems to me most likely that there was a lake at the south end of the plain, and that those cities were situate near its borders; their destruction was followed by the enlargement of the lake, and the ruin of some part of the plain on which they stood. It is indeed an almost universal opinion among the Arabs, that some of the ruins of these cities may yet be seen. Costigen found ruins, as his servant declared, which he took for the ruins of those cities; and Count Barteau states, that he saw at the south end of the lake old cisterns, and other things that indicated the former existence of towns. There is now not much doubt that we shall in due time have the facts so examined into and certified, as to add another proof to the many which have lately been given, of the verity and accuracy of the Scriptural account of things. While at Jerusalem, I had occasion to visit Jaffa. I rode down past Rumla, and reached Jaffa in about ten hours. My horse was not a good one; the day was warm, and I did not ride fast. I infer, from the time spent on the road, that the distance must be at least thirty-five miles, and possibly forty.
