In the Legion on a route march he would be carrying rifle, three hundred rounds of ammunition, knapsack and tent-pole, a weight of fifty kilogrammes or so. To-night he was free of all this, his own man. As he kept up the pursuit the thought suddenly occurred to him that the barracks would have long closed by this, and not answering to the roll call his name would be posted as a deserter. This thought amused him for a moment, then it troubled him. He had deserted from the regiment before; that always leaves a stain on a man's name, no matter how good his subsequent conduct may be. The punishment for a second attempt is very heavy and the Legion is deaf to excuses and very merciless. Stung by this, he determined to finish the business at once, if possible, close with his prey and chance it. He broke into a run, but, lo and behold, as though gifted with eyes in the back of his head, or a supernatural sense of hearing, Mansoor did likewise. Five minutes later, both men, as if by tacit consent, had fallen back into the old pace. There are occasions when men hold quite long conversations with one another without a word of speech, and whilst they are grasping for one another's throats. Mansoor was saying to Jacques, "If you increase your pace I will increase mine; there is nothing to be gained by you in overhauling me like that; quite the reverse, for, seeing that I have a long lead, you would be the most exhausted of the two if you managed to outstrip me. Besides, in a racing test you might not be able to do so." Jacques was saying, "That is true--curse you!--well, then, let's heel and toe it, I have the advantage of the practice marches of the Legion on my side, and I can stick to you till we both drop. I know, you have method in your game, for the further you lead me the more chance you have of falling in with some tribe of wandering Arabs who would back you against me. Well, I must take the chance." These two men had once known each other; at a distance, it is true, still they had known one another and exchanged greetings. Jacques had a reputation of his own in Sidi-bel-Abbès, and so had Mansoor. They knew one another's reputations. This knowledge helped in the mute conversation between the pursued and the pursuer. At dawn they had put some thirty kilometres between them and Sidi-bel-Abbès; the outline of the Tessala Mountains hardened against the fading darkness and then the sun rose, a ball of guinea-gold coloured, eye-dazzling fire, in a blue, still, silent sky. The solitude here was unbroken by any sign of life; grass patch, scrub bush, ash-grey-green cactus, all seemed petrified in their natural colours, unreal in the real and living sunlight. Forsaken, and given over to eternal silence.
