We were now attached to the 12th Cavalry Brigade, commanded by Brigadier-General J. T. Wigan, and on the 16th, 17th, and 18th August we took over D and E sections of the Desert Corps front line, relieving the 19th Indian Lancers and the 6th Indian Cavalry Regiments. We were unfortunately only a few days with the 12th Brigade, which was moved to Ludd soon after we were posted to it. The Jordan Valley, at the place where we were entrenched, is about fifteen miles wide and is over 1,200 feet below sea level. It is for the most part fairly flat, but is intersected here and there by huge ravines, which are in places quite narrow, and at others some hundreds of yards across, with sheer cliffs some thirty to fifty feet high as banks. Looking at the valley from the hills that border it, one would never suspect the existence of these great rifts. The River Jordan runs in the centre of one of these depressions, which in places is 50 to 100 feet below the ordinary level of the rest of the valley. The Wadi Mellahah is another huge cleft or rift, running about a mile to the west of, and more or less parallel to, the Jordan. It is some 10 miles long, and varies from a few score yards to a mile in width. Steep cliffs and slopes shut it in on both sides, and make the bed of the Mellahah about as hot and stifling a spot as can well be imagined, while, to add further abomination to it, noxious fumes arose in places from its barren and desolate looking sides and bed. A tiny, briny streamlet runs its straggling course through it in the dry season, although in places it spreads out into large reed-covered swamps. The water of this rivulet was so salt that a single drop was more than one could bear to take on the tip of one's tongue. We made our headquarters in this gully some three miles from where it flows into the Auja, of which it is a tributary, and here we fixed up a reed hut as our mess house, under the shade of the only tree in this depressing spot. Of course we had to keep down in the depths of the ravine, otherwise we would be seen and shelled by the Turks. This Mellahah Wadi had been made in the course of ages by the rush of water coming down from the Judæan range and from other hills to the north where there is a heavy annual rainfall. Here and there in the ravine, where it is at its broadest, stand isolated hillocks which the water has not worn away, and on these had been constructed some of our more northern redoubts; they were easy to defend and commanded a good view, for their tops were on a level with the surface of the surrounding valley. One of our redoubts was named "Salt," and just to the north of it a sparkling spring bubbled out of the side of the cliff. It looked so pure and inviting that I took a mouthful, and was nearly poisoned for my pains. It was the most briny, sulphurous liquid imaginable. There is a fortune awaiting the man who exploits its medicinal properties!
