It called David, too. The force and searching energy and fire in it stole through his veins, and drove from him the sense of futility and despondency which had so deeply added to his trouble. There was something for him, too, in that which held infatuated the minds of so many millions. A moment later Kaid and he faced each other again. "Effendina," he said, "thou wilt not desert our work now?" "Money--for this expedition? Thou hast it?" Kaid asked ironically. "I have but little money, and it must go to rebuild the mills, Effendina. I must have it of thee." "Let them remain in their ashes." "But thousands will have no work." "They had work before they were built, they will have work now they are gone." "Effendina, I stayed in Egypt at thy request. The work is thy work. Wilt thou desert it?" "The West lured me--by things that seemed. Now I know things as they are." "They will lure thee again to-morrow," said David firmly, but with a weight on his spirit. His eyes sought and held Kaid's. "It is too late to go back; we must go forward or we shall lose the Soudan, and a Mahdi and his men will be in Cairo in ten years." For an instant Kaid was startled. The old look of energy and purpose leaped up into his eye; but it faded quickly again. If, as the Italian physician more than hinted, his life hung by a thread, did it matter whether the barbarian came to Cairo? That was the business of those who came after. If Sharif was right, and his life was saved, there would be time enough to set things right. "I will not pour water on the sands to make an ocean," he answered. "Will a ship sail on the Sahara? Bismillah, it is all a dream! Harrik was right. But dost thou think to do with me as thou didst with Harrik?" he sneered. "Is it in thy mind?" David's patience broke down under the long provocation. "Know then, Effendina," he said angrily, "that I am not thy subject, nor one beholden to thee, nor thy slave. Upon terms well understood, I have laboured here. I have kept my obligations, and it is thy duty to keep thy obligations, though the hand of death were on thee. I know not what has poisoned thy mind, and driven thee from reason and from justice. I know that, Prince Pasha of Egypt as thou art, thou art as bound to me as any fellah that agrees to tend my door or row my boat. Thy compact with me is a compact with England, and it shall be kept, if thou art an honest man. Thou mayst find thousands in Egypt who will serve thee at any price, and bear thee in any mood. I have but one price. It is well known to thee. I will not be the target for thy black temper. This is not the middle ages; I am an Englishman, not a helot. The bond must be kept; thou shalt not play fast and loose. Money must be found; the expedition must go. But if thy purpose is now Harrik's purpose, then Europe should know, and Egypt also should know. I have been thy right hand, Effendina; I will not be thy old shoe, to be cast aside at thy will."
