The destiny of some men lies coiled within them, invisible as the blood of their hearts or the stuff of their will, working darkly, day by day and year after year, for their glory or for their destruction. The destiny of other men is an accident, a god from the machine or an enemy in ambush. Such was the destiny of Guy Matthews, as it was of how many other unsuspecting young men of his time. It would have been inconceivable to him, as he stood in his dark stone room listening to Magin's receding stamp, that anything could make him do what Magin demanded. Yet something did it--the last drop of the strange essence Dizful had been brewing for him. The letter that accomplished this miracle came to him by the hand of a Bakhtiari from Meidan-i-Naft. It said very little. It said so little, and that little so briefly, that Matthews, still preoccupied with his own quarrel, at first saw no reason why a stupid war on the Continent, and the consequent impossibility of telegraphing home except by way of India, should affect the oil-works, or why his friends should put him in the position of showing Magin the white feather. But as he turned over the Bakhtiari's scrap of paper the meaning of it grew, in the light of the very circumstances that made him hesitate, so portentously that he sent Abbas for horses. And before the Ramazan gun boomed again he was well on his way back to Meidan-i-Naft. There was something unreal to him about that night ride eastward across the dusty moonlit plain. He never forgot that night. The unexpectedness of it was only a part of the unreality. What pulled him up short was a new quality in the general unexpectedness of life. Life had always been, like the trip from which he was returning, more or less of a lark. Whereas it suddenly appeared that life might, perhaps, be very little of a lark. So far as he had ever pictured life to himself he had seen it as an extension of his ordered English countryside, beset by no hazard more searching than a hawthorne hedge. But the plain across which he rode gave him a new picture of it, lighted romantically enough by the moon, yet offering a rider magnificent chances to break his neck in some invisible nullah, if not to be waylaid by marauding Lurs or lions. It even began to come to this not too articulate young man that romance and reality might be the same thing, romance being what happens to the other fellow and reality being what happens to you. He looked up at the moon of war that had been heralded to him by cannon and tried to imagine what, under that same moon far away in Europe, was happening to the other fellow. For it was entirely on the cards that it might also happen to him, Guy Matthews, who had gone up the Ab-i-Diz for a lark! That his experience had an extraordinary air of having happened to some one else, as he went back in his mind to his cruise on the river, his meeting with the barge, his first glimpse of Dizful, the interlude of Bala Bala, the
