Haifa, April 30.—In my last letter I described the little-known hot sulphur springs of Amatha, with their extensive ruins, which indicate the celebrity they must have acquired in the days of the Romans. As the river Yarmuk above this point had, so far as I know, never been explored, I determined to push up the gorges through which it cleaves its way from the highlands of the Hauran to the valley of the Jordan. Some years ago I had crossed it about thirty miles higher up, where it flows across a plateau at an elevation of 1800 feet above the sea. I was now standing on its margin, 550 feet below the sea. In the course of this thirty miles, therefore, it has a fall of 2350 feet. In other words, it was a fair presumption that there was a waterfall somewhere between those two points which had never been visited. The inquiries which I made from the natives on the point were unsatisfactory in their result. They seemed unable to discriminate between a rapid and a waterfall, and although they told me of many places where the water rushed with great violence, they seemed to know of none where it was precipitous. Upon one point they were, unfortunately, all agreed, which was that there was no path up the river-side, and that it would be found impossible at this time of year, when the stream was flooded, to force a way up. However, we determined to try. We thought we should be more free in our movements if we were unhampered by a guide, and directed only by our topographical instincts. We therefore left our tents standing, as a sort of home on which to retreat in case of need, and struck across the small plain upon which the springs are situated, to a ford, which four days previously had been impracticable, but which we were assured we might now risk with safety. The stream was here a hundred yards broad, full of large rocks, and with a swift, turbid current that was by no means reassuring. The water came high up on our saddle-flaps, but we reached the other bank without mishap, and found ourselves skirting a dense thicket of tropical underwood, above which a grove of at least three hundred date-trees reared their tufted crests. It was a spot unlike any other to be found in Palestine, for, although the heat in the valley of the Jordan, owing to its depression below the sea, is as great as this, and at its southern extremity greater, nowhere throughout its length is to be found a spot where the vegetation is so dense and luxuriant. Here were wild orange, lemon, fig, almond, and mulberry trees, oleanders growing to a gigantic size, besides butm, sidr, carob, and other trees peculiar to the country, and thickets of cane twenty feet high, forming a splendid cover for the wild boars with which we were assured this jungle abounds.
