"Let go!" Geoff told the syce, and there for a moment he sat motionless, Sultan standing as still as any statue--his head thrown back, his muzzle raised, and his eyes gleaming wickedly. Then with a bound he leapt to one side--a leap which would have thrown the average rider--and a second later, shaking his head free, he went off towards the desert like the wind, as if determined to have his freedom. "Steady! Steady, boy, steady!" said Geoff, holding him firmly with the reins. "You're here to do what I want and not what you want; and, besides, a burst of speed so soon after coming ashore might be bad for you; you're coming back to let those officers take a good look at you." The mad impulse of the Arab to be off, to be galloping wildly across the loose sand and gravel thereabouts, to be hurtling amongst the palms which covered the country-side, was controlled in an instant, and with such little effort that those officers who watched could not discern it. Geoff brought his mount back towards the troops of horse at a steady trot, a trot in which Sultan showed magnificent action, so much so that riding him gracefully was a matter of difficulty. Then a gentle pressure of the reins again brought him to a standstill, his feet well spread, his head held high, those eyes of his gleaming and shining. Indeed, all could see the spirit of the horse, and none were surprised when, a moment later, as the Officer in Command approached, Sultan rose on his hind legs and thrashed the air, Geoff sitting him and talking to him gently. "A very handsome piece of goods, Keith," he heard, "'pon my word! I'm as envious as I can be; but in fairness to all of us you ought to take him out a little bit and give him a breather. Gently at first, and then some quick pace, so as to let him get rid of a little of that spirit. Otherwise he'll be kicking other horses in the ranks or disabling one of the officers." A gentle word from Geoff, the merest relaxation of the reins, and Sultan was off again, but curbed this time ever so gently; off at a trot again, showing that magnificent action with his fore legs, his quarters gleaming in the sunshine. And, slowly as they went, the pace increased till it became a canter, which Geoff allowed his mount to keep up until they had covered a good mile of desert--until, in fact, he was well out in the open and away from the palms which spread themselves some distance from the bank of the river. Then he pulled up his mount and patted him on the shoulder. "That's your first breather, old chap!" he said; "now I'll allow you to have a burst of speed till we are near the trees again, just to get rid of the devil in you. After that you'll behave yourself, and go along quietly like the rest of them. Now off!"
