The place where Piet labored at the stone was under the bank of the stream, where it ran deep and slow, and curved curiously between little hard headlands of rock and easy bosoms of sand; so that when he was plying the great sledge and cutting out the stone in big, flat cakes, he was hidden from the lads who dug on the foundations of the house, a couple of hundred paces away. There was little enough to fear now, but his old lore of war still governed him, and he carried his rifle to his work with him, and had chosen to work in a spot where he could not be suddenly approached by one coming secretly through the hummocks. Here, at noon, on the fourth or fifth day of the building, he was laboring happily. His was the part to swing the great sledge on the wedges; three, four full-bodied blows, each ringing true as a bell on the iron wedges, and a fat, flat slice of stone jarred loose from the body of the rock, to be hauled apart by the kafirs; and then in with the wedges again. He had joy in his strength, and in the pretty skill of never missing the head of the wedge; so that he worked on without fatigue and did not look about him. It was when another big flake of stone was broken away, that an exclamation from one of the kafirs made him turn sharply to look up-stream. He was never sure what manner of man he saw, watching him from the far side of the spruit. For one thing, there was sweat in his eyes; for another, he turned to grasp his rifle, and when he turned back, the man was gone. But in the couple of moments that the man was in view, Piet saw that he was white, a short, strongly-built white man, dark against the pale sand. And though he could never find a phrase for the impression in his mind, the thing that puzzled him was the utter strangeness of the man's appearance. Whether it was the fashion of his clothes, his attitude, his looks, or just the mere whole of him, he could never explain. But, "it seemed to me as if he were none of God's making," he always added. It was a matter of no more than a couple of breaths; then his bewilderment broke up, and caution took its place. He bustled his kafirs together and shepherded them out of the streambed and back to the camp, coming last with his rifle cocked in the crook of his arm to guard against any possible danger. He saw that work had ceased in the foundations of the house; the lads and the kafirs were gathered in a knot in the pit, and their voices buzzed in talk. But he gave no notice to that. "We are being watched," he said to them. "Back to the laager and get your guns." And once again the square of wagons became a fort, and the little family stood to its arms against all comers, for its right to live in the place it had chosen.
