Beyond Kurna the Tigris takes some immense curves so that at times you seem to see the sails of mahallas all round the horizon. We lay on deck, staring idly at the unvarying landscape which quivered under the sun. Occasionally Arab villages were passed, constructed out of the matting made from reeds, which is a local industry. The reeds grow in big patches all the way up the river banks. On the second night we tied up below Ezra's tomb. There was local Arab trouble in this part at the time and we passed an outpost of native troops; also a mud hut, standing solitary in a swamp in the plain and bearing the words "Leicester Lounge" in black lettering. It seemed deserted.

At night there was a lot of lamp-signalling all round the horizon in naval code. One caught M.M.O. repeatedly and then a lot of figures. Some fires lit up the sky line to the north. On that night the heat was beyond description. A plague of sand-flies and mosquitoes descended on the ship. No one slept a wink. The mules screamed and kicked. There was not a breath of air. A heavy smell pervaded the ship, and at times it seemed that one's mind wandered a little. Before dawn a great cry came out of the steamy darkness from some worshipping Arab and was repeated twice. After a long silence a cock crew far across the plain and was answered a hundred times. Then came a misty blue light and a sudden glare of yellow. The day had begun and the engines started.

A monitor passed, bristling with guns and painted a vivid green. Ezra's tomb is a mosque standing stark on the brown plain beside the river in a clump of palms. It is kept in beautiful preservation, for it is visited by pilgrim Jews. Against the lovely blue of the dome, with its circle of gold, a tall palm leans, bending sharply inward as if to kiss the Prophet's last resting-place in some sudden mood of devotion. Some way above it lies a big village, and as we passed crowds of Arabs lined the bank. Naked boys dived into the river after money. The women, dashing types with nose rings, clad in robes of wonderful vermilion and purple colours, ran along the banks with fowls and eggs for sale. Herds of black buffalo, submerged up to the nose, basked in the water.

At one lonely place we passed a small shelter, a roof of yellow matting supported by a few posts, containing six rather pale-hued women with richly coloured robes and bangles seated in a semi-circle on the ground. Outside stood the lord of the manor, very swarthy, in dazzling white, with a rifle slung over his shoulder, scowling ferociously as he surveyed the plains. He was a kind of policeman, I believe, in our pay. At any rate he seemed to be, like policemen in general, a strong lover of domestic life. Six wives may have contributed a little towards overcoming the extreme monotony of life in the place.

Above Ezra's tomb begin the Narrows. The Tigris becomes very narrow, pouring its filthy yellow water at a great speed between the sharply cut banks. The turns are so sharp, being at times much more acute than a right angle, that the only way to get round is to charge the bank, bump off with a great churning of paddles and creaking of lashings and clanging of the telegraph from the bridge, and work the steamer's nose into the centre of the stream again. The banks, at these spots, are perfectly smooth and polished owing to the constant impacts. By themselves the river steamers could get round more skilfully, but with their clumsy barges on each side it was impossible. The S-boats—the stern wheelers—of which there are only a few, do not carry barges, and therefore their handiness and speed are much greater. They can run from Basra to Sheik Saad, close to the front, within three days, and can travel by night if necessary.

At three in the afternoon as we bumped and scraped and panted up the tortuous river, we came on the familiar sight of a convoy stuck, broadside on, across the river in front of us. A little smoke came from her funnel. The sun beat savagely down on her apparently deserted decks. Behind her there was nothing but shimmering plain and the occasional flash of water. Our engine-room telegraph rang. The engines stopped and we slewed into the bank and dropped anchor. Then the skipper and his navigating lieutenants withdrew to their cabins and the engine-room staff, composed of an Englishman who had run boats up to Baghdad for ten years, and a few Christian Baghdadies—powerful dark men, who seemed to speak a kind of French—disposed themselves for rest on the lower deck, and a great peace descended on the scene. Away over the horizon, north and south, some columns of smoke were visible coming from other convoys that were converging on the Narrows. It was necessary to wait for the tide, as well as for a tug. There was nothing to do but to watch the plain. At first sight it appeared lifeless, an expanse of golden browns, reds and yellows, with a sharp purple rim on the skyline. But closer observation showed long lines of cattle, mere dots in the distance, moving slowly in search of pasture. In the shadow of a hummock an Arab boy and girl sat together motionless. A mile along the level two Arabs were rhythmically swinging water up from a cutting by means of a shallow vessel with ropes attached to the side. The flash of it caught the eye, and there was a patch of vivid emerald where the water fell. To the north it was possible to make out the arms of a semaphore lying idle. There was no sound in the place. The river itself flowed silently. Only the occasional deep drone of a hornet or the note of a mosquito came to the ear. The sun seemed to be drawing the land together, sucking up all the sap it contained.

As we sat and gazed at these bending and twisting Narrows the idea arose that it might be possible, by a little cutting, to do away with the worst bits and open up a straight channel. For there were two main places of obstruction, called the Devil's Elbow and Pear Drop Reach. But it is necessary to say this with caution, for tampering with great rivers like the Tigris may cause unthought-of trouble. It upsets the natural balance of the waters.

Gradually the other convoys drew near and dropped anchor above and below the obstructing vessel. Some native troops in one of them got out on the bank and began to bathe, or wandered about looking for fuel to cook their evening meal, and towards evening a string of Arab women and children, from some remote village, came along with eggs and melons and pumpkins. In the meanwhile a kind of activity prevailed in the region of the obstruction. A tug boat appeared and ropes were stretched out to posts on the land and the water was being churned to foam by the paddles. It was said that General Y was on a convoy ahead, and General X, who was going up to replace him, was in a convoy behind us. It was possible to count seven convoys in all, and smoke columns were still rising in the south. It was not until darkness fell that the ship was pulled off, and it was too late to move on that night. So we ate our bully beef and settled down for the night. Once more our sensations were indescribable. The sand-flies were like a million little red-hot wires. There was not a breath of air and the mules screamed and fought and gasped alongside. One hundred and fifty people packed on a small deck, round a funnel that is still burning hot, make a poor job of sleeping in such a climate.

It was the devout prayer of everyone that we might reach our destination next day and get off the ship and away from those mules. That was not to be. We reached Amara in the darkness of the evening, and anchored near the Rawal Pindi Hospital. Owing to a case of cholera that had developed that day on the starboard barge, we were put in quarantine, so it was necessary to unpack one's kit again and shake down for the night on deck. One of the most refractory mules kicked itself loose of its moorings and fell into the stream in the darkness. Several men risked their lives in rescuing it. One would have thought, seeing that it had been the noisiest and most vicious brute on the barge, that drowning was scarcely good enough for it. And what is a wife to think of her husband when she is told that he was drowned while gallantly attempting to rescue from the swift current of the Tigris a mule that could swim far better than he could? As no one was drowned, perhaps it is unnecessary to ask the question.
