Presently the sun burst triumphantly through the mist and disclosed a bivouac of thousands of men and horses lying on the edge of a limitless desert. As far as the eye could see was a yellow sandy plain. This was skirted on the Cairo side by the main Heliopolis-Suez road, which ran east and west through the camp, and was bounded on the far horizon by a range of low brown sandhills. Soon all hands were at work pitching headquarters and the supply depots south of this main road and the other units north of it. A new road at right angles to the main road was constructed in a northerly direction--on the right of which the mounted rifles, artillery and ambulance placed their tents and horse lines, while the infantry occupied the whole of the left hand side. Water-pipes had been laid on and watering troughs for horses were already on the ground, and by evening some order had been evolved, though many troops had again to bivouac in the open, realizing that, notwithstanding the poets, the sands of the desert do become very cold about 2 o'clock in the morning. By the end of a week all the ships had been cleared of men, horses and stores, and the three colonial camps had shaken down into something like order--the Australian infantry at Mena, under the shadow of the great Pyramids; the Australian Light Horse at Medi; and the New Zealanders at Zeitoun. The horses were not fit for either transport work or driving, but for a week or two were exercised in progressive work until able to stand the strain of manoeuvres. Out of nearly four thousand horses only eighty-eight failed to survive the buffetting journey through the Tasman Sea and Great Australian Bight, the sweltering heat of the Indian Ocean and the Red Sea, and the hazardous acclimatization in a hot and sandy desert--there they stood in long and polished rows, chewing the succulent berseem and munching the dry and uninviting tibbin, which apparently caused the horses much less concern than it did the anxious troopers. [Illustration: [_Photo by the Author_ THE WATER CART ON THE DESERT.] Training commenced in earnest. Early every morning the infantry battalions paraded in full marching order and trudged through miles of sandy desert. Like so much of the soldier's life, this work was not interesting, but it was necessary; with clothing designed for a cool climate the long columns swung out along the never-ending sands, hardening the hardy ones, the cruel desert slowly but mercilessly winnowing out the few unfit. If a man had a bad knee or a weak chest, those weary sweltering marches and misty nights sought out the weak, who were sent to the Egyptian Army Hospital at Abassia, where Australian nurses of Queen Alexandra's Imperial Nursing Service nursed them tenderly back to health, or sent them broken-hearted to convalesce at Alexandria preparatory to their long sea voyage home.
