But a thought struck him, and fetching up a yoke of the oxen which were browsing contentedly a half-mile away, Dyke hitched them on to the dissel-boom, and, after some difficulty, managed to get the wagon drawn close up to the fence, and within a few yards of the door. "Duke will be there, and I should hear any one who came," he said to himself, and once more set the oxen free to go lowing back to their poor pasture with the rest of the team, which he had had hard work to keep from following him at the first. And now, tired out with his exertions at a time when the hot sun was blazing on high, and beginning to feel a bit dispirited, he entered the house again, to be cast down as low as ever, for once more Emson was suffering terribly from the fit, which seemed to come on as nearly as could be at the same time daily. Dyke knew that he ought to have been prepared for it, but he was not, for it again took him by surprise, and the medicine which he administered, and his brother took automatically, seemed to have no effect whatever. He bathed and applied evaporating bandages to the poor fellow's temples, but the fever had the mastery, and kept it for hours, while Dyke could at last do nothing but hold the burning hand in his, with despair coming over him, just as the gloom succeeded the setting of the sun. Then, just as the boy was thinking that no fit had been so long as this, and that Emson was growing far weaker, the heat and alternate shivering suddenly ceased, and with a deep sigh he dropped off to sleep. Dyke sat watching for a time, and then, finding that Emson was getting cooler and cooler, and the sleep apparently more natural and right, he began to think of his plans for the evening. He was determined to keep awake this time, and to do this he felt that he must have company. The Kaffirs were hardly likely to come by night, he felt, and so he would not leave the dog to watch, but going out, called him down out of the wagon, tied down the canvas curtains back and front, fed the dog well, and stood at the door waiting until the faithful beast had finished, watching the while. Then once more he noticed the peculiar light at the back of the kopje, looking as if the moon were rising, though that could not be, for there was no moon visible till long after midnight. But Dyke was too weary to study a question of light or shadow, and as soon as Duke had finished he called the dog in, closed the door, did what he could to make poor Emson comfortable, and sat down to pass the night watching. But nature said again that he should pass it sleeping, and in a few minutes, after fighting hard against the sensation of intense drowsiness, he dropped off fast as on the previous night, but started into wakefulness in the intense darkness, and sat up listening to the low growling of the dog, and a terrible bellowing which came from the pens, where the cattle should be, if they had returned after their many hours' liberty.
