He saw occasionally vultures, storks, and pelicans; and now and then a herd of beautiful antelopes swept past him; but--as he thanked heaven--no Bedouins. More than once he came upon nitre springing up in the sandy waste, like crystallised fruit. At times these spots seemed as if overgrown by moss and coated with hoar frost--hoar frost under a fervid Egyptian sun; and according to the quantity of the nitre, their fantastic shapes were either a dazzling white, or more or less tinted by the yellow hue of the sand. More than once in his fitful slumbers by night under the baleful dew, there came before him in a dream the agony of his lurking on the summit of the tomb in momentary dread of discovery, and then he was again closing in combat hand-in-hand with Abdallah, the aspect of whose dark face, with gleaming eyes and glistening teeth, curiously blended with an idea of Holcroft, came vividly before him; and then, when just in the act of plunging in his shortened sword-blade, he would awake with a nervous start to find himself still in solitude with quiet stars looking down upon him. At last when about to sink he saw before him the well-known fringes of greenery and foliage that indicate the line of a canal, and it proved to be a portion of that of Moses, and a cry of joy escaped him when he heard the whistle of a locomotive and saw the welcome smoke of a train running westward. How much the sound and sight we deem alike so hideous spoke to his heart of home, of ease, of peace, safety, and civilisation. In short, he soon discovered that he was midway between Kassassin and Mahsameh and by a liberal promise of backsheesh to an Egyptian labourer whom he met, and whose assistance he solicited, he reached a railway station and obtained all the succour he needed from the European officials there. By them he was placed in a train for Ismailia, and ere long he saw once more those places which were familiar to him as having passed them with the troops--Ramses, Tel-el-Mahuta, and El-Magfar, where the Black Watch had encamped, and where he had befriended Zeid-el-Ourdeh; and ere long he could recognise, when he had left the sea of sand behind him, the white-walled houses of Ismailia against the deep blue of the sky, and the tall forest of masts, those of our transports and warships in the adjoining lake of Timsah. He had no recollection of more, or even of reaching the railway station. His heart beat wildly, his head swam round him, and a darkness seemed to envelop him. He had fainted. On partially recovering he found himself in bed, but he knew not where, and dimly seen, as in a glass, he thought he saw Evan Cameron bending over him--Evan looking pale and wan as when he buried him in the sand. 'Oh, God,' sighed Allan, as he closed his eyes to shut the vision out, 'is this madness or delirium that has come upon me?' CHAPTER XVI. EASTWARD HO!
