'Quick, Carslogie,' cried Allan. 'We have no time to lose. The bugles will sound immediately.' And Carslogie went on his way with the air of a man who thought the world would be none the worse for having a Bedouin the less in it. In his own language, and in terms peculiarly his own, Allan could make out that the sheikh was thanking him in a low and earnest voice, and adding that while life lasted he 'would always deem him as a brother. You infidels are powerful as the genii of old; you can flash a light at night brilliant as that of the sun at noon; you have another light that springs from the unseen air. I have seen it in the streets of Cairo' (no doubt referring to gas); 'and you can send your thoughts from land to land under the sea more swiftly than even the Afrite did in the days of Solomon; and I fear that from your hands the Egyptians will suffer such chastisement as fell on the people of Noah, of Ad, and of Thamud,' he added, wearily and sadly, as his head fell on one side. A party of the ambulance had now come, and Allan informed him that he was to be sent to Ismailia. He did more; he placed some money in his hand wherewith to procure necessaries, and, while the eyes of the Bedouin gleamed with gratitude, his brown mahogany and attenuated fingers closed avariciously and tightly on such an unusual gift as coins. ''Pon my soul, Allan Graham,' said Carslogie, 'considering how these rascals treated our wounded at Kassassin, your humanity, to say the least of it, seems to me to be a little misplaced.' 'Perhaps; but I cannot help it. I feel a little tender-hearted just now,' said Allan, with a smile, as the wounded Bedouin--of whom he had not seen the last--was borne away. The pipes struck up, and once more the columns began a ten-miles' march to Mahsameh. The Gordon Highlanders were in advance, the Camerons next, then came the Highland Light Infantry, and then the Black Watch, all toiling through the soft, deep sand. These splendid regiments were all marching in massed columns, at one pace interval, the cavalry moving with them collaterally on one flank, and the artillery on the other, clattering along, with spunges, buckets, spare wheels, and forge waggons--all forming a grand, impressive spectacle in the midst of the wide Egyptian desert.
