"Handles the beast as if born to it," declared the Commanding Officer, as he watched the figures of man and horse racing towards him, while his brother officers crowded about him. "That lad has hands and a seat to be proud of, and the beast he rides is the best bit of horse-flesh I've seen--and that's saying something." There was no doubt, in fact, that Geoff's arrival on the scene, his unexpected attachment to these horse-soldiers, his unconscious exhibition of horsemanship, and his possession of that fine Arab, had created quite an enviable impression upon the officers who were to be his companions. "A young chap, such as he was, who could ride so well, who had the pluck to manage such a horse, must be a good fellow," they told themselves; and, thinking that, the information which was now given them--that Geoff was no new-comer to Mesopotamia, but had spent some months there with a famous Indian "political", and even knew the languages--prepossessed them still more in his favour. "You'll do, my lad," the Commanding Officer whispered in his ear some few minutes later, when Geoff had dismounted, and had handed over Sultan to the syce. "It wants judgment to ride a beast like that, and judgment's the virtue required for the job to which you have been appointed. Now, Keith, our orders have come, and here are the maps; pop this one into your map-case. I shall take the troops up beside the river towards Basra, and if it seems necessary I shall send one troop off to my right to see what's happening farther out in the desert." There were sharp words of command, and then a whistle blew, at which those stalwart Indian soldiers mounted their horses as one man, and sat there like so many dusky statues; then the whistle sounded again, and the cavalcade moved off, Geoff, at the invitation of the Commanding Officer, riding beside him. It was as well, perhaps, for our hero that he was all unconscious of the fact that those Indian cavalry officers were not the only witnesses of that exhibition he had given with Sultan, and that other eyes than the curious ones of the natives of those parts followed the troops of horse, and his own upright figure, as they swung away from the site of disembarkation. It might have turned his head, and robbed him of his natural modesty, had he known that numbers of the Head-quarters Staff were outside their hut, looking on at this first movement of the expedition in Mesopotamia; and it would most certainly have caused a flush to rise to his cheeks, and possibly, had he not been a steady, sensible fellow, might have induced a degree of swollen-headedness, had he been able to hear the remarks of some of those senior officers. For, like those with the Indian horse, they, too, had fixed their eyes on Sultan, had seen the masterly way in which he was managed, and had admired the horsemanship of this new-comer amongst junior officers.
