“I—will—not!” said West emphatically.

But he did, as he sat back resting his shoulders against the rock and gazing out from the mouth of the cave where they had made themselves comfortable at the beautiful sunlit veldt, till it all grew dark as if a veil had been drawn over his eyes.

It was only the lids which had closed, and then, perfectly unconscious, he sank over sidewise till he lay prone on the soft sand, sleeping heavily, till a hand was laid upon his shoulder and he started into wakefulness, to see that the sun had set, that the shadows were gathering over the veldt, and then that Ingleborough was smiling in his face.

“Rested, old man?” he said. “That’s right. The nags have had a splendid feed, and they are ready for their night’s work. I haven’t seen a soul stirring. Come on! Let’s have a good drink of water and a feed, and by that time we ought to be ready to start.”

“We ought to cross the Vaal before morning,” said West.

“I doubt it,” was the reply, “for it will be rather a job, as we shall find the enemy about there. If we get across to-morrow night we shall have done well.”

“But we shall never get to Mafeking like this.”

“It’s going to be a harder task than you thought for when you volunteered so lightly, my dear boy; but we’ve undertaken to do it, and do it we will. It isn’t a work of hours nor days. It may take us weeks. Come along! I’m hungry, and so are you.”

“But tell me,” said West, “how long have you been awake?”

“Not above a quarter of an hour. We must have sleep and rest as well as food. When we’ve had the last we shall be ready for anything through the night.”
