At first I feared lest we encounter Arab raiders, who might have attacked the Camel Corps in ignorance; so I put forward with my men some half-mile before the column. As we slipped on, gradually we became aware of night-birds, flying up from under our feet in numbers, black and large. They increased, till it seemed as though the earth was carpeted in birds, so thickly did they start up, but in dead silence, and dizzily, wheeling about us in circles, like feathers in a soundless whirl of wind. The weaving curves of their mad flight spun into my brain. Their number and quietness terrified my men, who unslung their rifles, and lashed bullet after bullet into the flutter. After two miles the night became empty again; and at last we LAY down and slept in the fragrant wormwood, till the sun roused us out.

In the afternoon, tired, we came to Kusair el Amra, the little hunting lodge of Harith, the Shepherd King, a patron of poets; it stood beautifully against its background of bosky rustling trees. Buxton put headquarters in the cool dusk of its hall, and we lay there puzzling out the worn frescoes of the wall, with more laughter than moral profit. Of the men, some sheltered themselves in other rooms, most, with the camels, stretched themselves beneath the trees, for a slumberous afternoon and evening. The aeroplanes had not found us--could not find us here. To-morrow there was Azrak, and fresh water to replace this stuff of Bair which, with the passing days, was getting too tasty for our liking.

Also Azrak was a famous place, queen of these oases, more beautiful than Amruh, with its verdure and running springs. I had promised everyone a bathe; the Englishmen, not washed since Akaba, were longing towards it. Meanwhile, Amruh was wonderful. They asked me with astonishment who were these Kings of Ghassan with the unfamiliar halls and pictures. I could tell them vague tales of their poetry, and cruel wars: but it seemed so distant and tinselled an age.

Next day we walked gently to Azrak. When we were over the last ridge of lava-pebbles and saw the ring of the Mejabar graves, that most beautifully put of cemeteries, I trotted forward with my men, to be sure against accident in the place, and to feel again its remoteness before the others came. These soldiers seemed so secure that I dreaded lest Azrak lose its rareness and be drawn back to the tide of life which had left it a thousand years ago.

However, both fears were silly. Azrak was empty of Arabs, beautiful as ever, and even more beautiful a little later when its shining pools were brilliant with the white bodies of our men swimming, and the slow drift of the wind through its reeds was pointed by their gay shouts and splashing echoed off the water. We made a great pit, and buried our tons of gun-cotton, for the Deraa expedition in September; and then roamed about collecting the scarlet sweet-water-berry of the Saa bushes. 'Sherari grapes' my followers, indulgent to our caprice, called them.

We rested there two days, the refreshment of the pools being so great. Buxton rode with me to the fort, to examine the altar of Diocletian and Maximian, meaning to add a word in favour of King George the Fifth; but our stay was poisoned by the grey flies, and then ruined by a tragic accident. An Arab, shooting fish in the fort pool, dropped his rifle, which exploded and killed instantly Lieutenant Rowan, of the Scottish Horse. We buried him in the little Mejaber graveyard, whose spotless quiet had long been my envy.

On the third day we marched past Ammari, across Jesha to near the Thlaithukhwat, the old country whose almost imperceptible variations I had come to know. By the Hadi we felt at home, and made a night-march, the men's strident yells of 'Are we well fed? No'. 'Do we see life? Yes', thundering up the long slopes after me. When they tired of telling the truth I could hear the rattle of their accoutrements hitched over the wooden saddles--eleven or fifteen hitchings they had, each time they loaded up, in place of the Arab's all-embracing saddle-bag thrown on in one movement.

I was so bound up in their dark body and tail behind me, that I, too, lost my way between the Hadi and Bair. However, till dawn we steered by the stars (the men's next meal was in Bair, for yesterday their iron ration was exhausted), and day broke on us in a wooded valley which was certainly Wadi Bair; but for my life I could not tell if we were above or below the wells. I confessed my fault to Buxton and Marshall and we tettered for a while, till, by chance, Sagr ibn Shaalan, one of our old allies of the distant days of Wejh, rode down the track, and put us on the road. An hour later the Camel Corps had new rations and their old tents by the wells, and found that Salama, the provident Egyptian doctor, calculating their return to-day, had already filled the drinking cisterns with enough water to slake the half of their thirsty beasts.

I determined to go into Aba el Lissan with the armoured cars, for Buxton was now on proved ground among friends, and could do without my help. So we drove fast down the scarp to the Jefer flat, and skipped across it at sixty miles an hour, ourselves the leading car. We threw up such a dust-cloud that we lost our sister, and when we reached the south edge of the flat she was nowhere visible. Probably tyre trouble, so we sat down to wait, gazing back into the dappled waves of mirage which streamed over the ground. Their dark vapour, below the pale sky (which got more and more blue as it went higher) shifted a dozen times in the hour, giving us a false alarm of our coming friends; but at last, through the greyness, came spinning a black spot wagging a long trail of sun-shining dust.

This was Greenhill tearing after, at speed through the shrivelling air, which eddied about his burning metal turret, making it so hot that its naked steel seared the bare arms and knees of the crew whenever the huge car lurched in the soft heat-powdered ground, whose carpeted dust lay waiting for the low autumn wind to sweep it across the open in a blinding choking storm.

Our car stood tyre-deep, and, while we waited, the men slopped petrol on a hillock of dust and boiled tea for us--Army tea, as full of leaves as flood water, and yellow with tinned milk, but good for parched throats. While we drank the others drew alongside, and reported two bursts of Beldam tubes in the heat of their swoop at a mile a minute across the scorching plain. We gave them of our boiled tea, and laughing they knocked the dust off their faces with oily hands. They looked aged, with its greyness in their bleached eyebrows and eyelashes and in the pores of their faces, except where the sweat had washed dark-edged furrows through to the red skin.

They drank hurriedly (for the sun was falling, and we had yet fifty miles to go), throwing out the last dregs on the ground, where the drops ran apart like quicksilver upon the dusty surface till they were clotted and sank in speckled shot-holes over its drifted grey-ness. Then we drove through the ruined railway to Aba el Lissan, where Joyce, Dawnay and Young reported all going marvellously. In fact, preparations were complete, and they were breaking up, Joyce for Cairo to see a dentist, Dawnay for G.H.Q., to tell Allenby we were prosperous and obedient.
