The Boer puzzled us. It was not because he loomed so big in the haze against the sunset; but he seemed at a mile's distance to detect us. We thought the cover perfect, for the hackthorn tops were higher than our horses' heads. If he from so far could see patches of khaki through bushes, his eyes must be better than our fieldglasses. If he did not see us, why did he wave his hat as in salutation?

"Maybe he only suspect one patrol at de ford. Vat you t'ink, Sergeant McTavish?" said Lieutenant Deschamps to me.

"Perhaps he thinks some of his own kind may hold the ford," I suggested.

The others said nothing. They were fifteen French Canadians, including Corporal Jongers. We lay still behind our prone horses, and kept our Krags on the Boer.

He seemed to diminish as he advanced slowly from the mirage, but still he looked uncommonly big—and venerable, too. His hair and beard grew long and white, though he sat up as alert as any young man. At ten yards a pack-pony followed him. When half a mile away the burgher raised both hands above his head.

"He come for surrender, you t'ink, sergeant?" Lieutenant Deschamps is a gentleman. Because I was of another race he always treated me with more than the consideration due to a good non-com. Or possibly it was because he knew I had been advocate in Montreal before joining the mounted Canadian contingent.

"Better keep down and keep him covered," I replied. "That may be a signal." I stared about the horizon. The veldt was bare, except for the straggle of hackthorns fringing the curve about the ford. There could be no other Boer within three miles of us, unless hidden by the meanderings of the Wolwe, which runs twelve feet below the plain. But we had searched ten miles of its bed during the day. Westward lay the kopjes from among which the old Boer had apparently ridden.

He came calmly down the breach of the opposite bank and as far as the middle of the brawling shallow within fifty yards of us before Deschamps cried "Halt!" At the word we sprang up, accoutrements rattling, horses snorting. The old burgher looked up at us quizzically, passing his hand down his beard and gathering its length above his mouth before he spoke.

"Take care some of those guns don't go off," he said, with no trace of Dutch accent.

"You surrender?" Deschamps stepped forward.

"Sir, I am going to Swartzdorp. Did you not see me hold up my hands?"

"But for sure you could not see us here?"

He smiled and pointed up to the sky. In the blue a vulture swung wide above us. "So I knew," said the burgher, "Khakis were hiding. Boers would have come out. They would have recognized me."

"Your name?"

"Emanuel Swartz."

"Bon! The great landowner! I have much pleasure to see you. Come in, monsieur. Eef only you brought in your commando, how glad!"

"They may come yet," he said. "It depends." He shook his rein, and the big bay brought him up the breach into the midst of us. The pack-pony, which had imitated his halt, followed.

"You will not stop me. I have private business at Swartzdorp," he said.

"Truly I regret," said Deschamps. "But my orders! Here you must stay, monsieur, this night. To-morrow General Pole. He will be most glad to parole you, I have hope."

"Oh, very well, lieutenant," said Swartz, philosophically. "I dare say he won't send me to St. Helena." He dismounted, leaving his Mauser strapped to his saddle. Then he handed me his bandoleer. "I make you welcome to my pack also," he said hospitably. "There's some biltong and meal. Perhaps it will improve your fare."

"It will be poor stuff if it doesn't," I told him.

"You give your parole, sir?" asked Deschamps.

"For the night, yes. I will not try to escape."

His cordial, easy accents came with a certain surprising effect from one who was so unkempt and, in spite of his years, so formidable. I had never before seen one of the great Boer land-owners. In his manner one could perceive, if not a certain condescension, at least the elevated kindness of a patriarchal gentleman accustomed to warm by affability the hearts of many descendants and dependents. About Swartzdorp we had heard much of his English mother, his English wife, and his lifelong friendship with English officers and gentlemen. It did not seem surprising that he should have come in voluntarily now that Bloemfontein and Pretoria were in Lord Roberts's hands.

It was cold for us in khaki that evening by the Wolwe, though we did not lack overcoats. The spruit tinkled icily along patches of gravel in the blue clay, and late June's high moon seemed pouring down a Canadian wintriness. "No fire," ordered Deschamps, lest far-sighted Boer parties, skilled in surprises, might locate us. But the old burgher showed how to make small glowing heaps of dry offal, which had been plentifully left of old by troops of deer and antelope coming to drink at the spruit. Over one of these tiny smokeless fires our lieutenant sat with the prisoner. I think I see again the reflection of the little flame flickering on the old giant's enormous beard and shapely outspread hands.

We had supped heavily on his meat and meal, but sleep in that nipping air came by dozes only, and drowsiness departed when digestion had relieved repletion. At midnight, when the vedettes were changed and the moon sagged low, we all were more wakeful than early in the evening. There had been little talk, and that in the low voices of endurance; but now Deschamps and Swartz fell into discourse about the Kimberley mines. This led to discussing the greater diamonds of South Africa, and so on till the burgher began a story stranger than fiction:

"One of the biggest stones ever taken from blue clay is still uncut. It has never been offered for sale. Near this very place it was found by Vassell Swartz, my cousin. The man is not rich even for a Free State burgher. He is fond of money. He believes his diamond to be worth twelve thousand pounds. No man could wish harder to sell anything. And yet he has not offered it. He has not even shown it. His wife has not seen it. He has had it constantly near him for eleven years. He has handled it frequently—in its setting. But he has not ventured to look at it since the morning after he found it. You wonder at that. Is it possible a rough diamond can shine so bright as dangerously to dazzle the eyes? No; Vassell would be glad to stare at it all day. But its setting prevents him. And yet he set it himself."

The old burgher paused and looked about on our puzzled faces with some air of satisfaction at their interest.

"It is quite a riddle," said Deschamps.

"So it is. And I will make it harder. You have been told that we Boers think nothing of killing Kaffirs? But all Swartzdorp could tell you that my cousin Vassell could scarcely bear to let a Kaffir out of his sight. That is mysterious? Well, I will not go on talking in parables. I will tell you the thing just as I heard it from Vassell or know about it myself.

"Eleven years ago, Vassell and his brother, my cousin Claas, went off as usual to Makori's country beyond the Limpopo, elephant-hunting. Ivory was so plenty that they trekked back a month earlier than they had expected. On the return Vassell's riding-horse fell lame not long after crossing this very Wolwe spruit by a higher ford. My cousin gave the beast no rest till evening, and no attention until after they had made a laager against lions and had eaten supper. Then he took a brand from the fire and looked into the hoof. In it he found a whitish stone of about the bigness of an elephant-bullet of six to the pound. It was of the colour of alum, and in the torchlight it glistened as the scale of a fish.

"Vassell had never seen a rough diamond. And he had heard of diamonds as brighter than glittering glass. He thought only that the pebble was a pretty stone. The man's heart was soft with nearing his wife and children, so he slipped the pebble into his empty elephant-bullet pouch, thinking to give it for a toy to his little Anna. There it lay forgotten until his fingers went groping for a bullet at the next daybreak. Kaffirs were then trying to rush my cousins' laager.

"Wild Kaffirs these were, driven from Kimberley for unruliness in drink. They were going back to their tribe; they had come far without food, and they smelled the meat and meal in the wagons—so Matakit afterward told. But no hunger could have driven them against a Boer laager. They mistook the wagons for the wagons of Englishmen."

The French Canadians smiled unoffended, but my jaws snapped. Swartz turned to me courteously:

"They mistook the wagons for those of English traders unskilled in arms and trekking provisions to the mines. Though their first rush showed them their mistake, they went mad over their losses and came on twice more. Then they guessed, from the way my cousins reserved their fire, that their ammunition was low. So Matakit howled them on for a fourth rush.

"My cousins and their six Christian Kaffirs were now in alarm, for their cartridges were nearly all gone. It was then that Vassell's fingers groped in his elephant-bullet pouch, where he felt something rounding out the leather. That was the forgotten pebble. But its bigness was too great for the muzzle-loading elephant-rifle. So my cousin rammed it into the wide-mouthed, old-fashioned roer, a blunderbuss that our fathers' fathers praised because it frightened Kaffirs more than it hurt them. In justice to the roer it should have been loaded with a handful of slugs. But with only powder and the pebble it made such flash and noise that all the living wild blacks, but one, ran away howling. The one that fell before Vassell's pebble was the biggest of all, and their leader. There he lay kicking and bellowing like a buffalo bull, ten yards from the wagons.

"'While he bawled we knelt in the laager,' Vassell told me, 'and we offered up thanks for this our deliverance, even like unto the deliverance of David by the pebble of the brook.'

"Then they ate breakfast while their Kaffirs inspanned, and still the wild one roared.

"'It would be merciful, brother Vassell,' said Claas as they drank coffee, 'to put the Lord's creature out of his pain.'

"'Nay,' said Vassell; 'my conscience will not consent to what Free State law might call murder. And, moreover, the Kaffir's pain is a plain judgment of the Almighty.' Vassell is a dopper, like Oom Paul, and a dopper is quick to see the Almighty operating through himself. So they left the black thief gnashing, with five more who lay still, meat for vultures' beaks or lions' jaws.

"In four or five hours' time my cousins were nigh to Truter's drift on the Modder. There they saw two Englishmen and one Israelite digging into the blue-clay shoal.

"'Good day,' shouts Claas. 'What are you digging for?'

"'Diamonds, Dutchman, d—n you,' said the Englishmen, laughing.

"They came up out of the river-bed and showed my cousins four small rough stones which they had found elsewhere.

"Vassell looked closely at the stones. Then he knew that his pebble had been a great gem. He put innocent, simple dopper questions about the value of diamonds. And the Israelite said that a first-rate stone of the bigness of more than an elephant-bullet would be worth from twelve to twenty thousand pounds. Vassell felt that Israelite's eyes piercing him, and so he gave no more sign of excitement than a skull. But he was wondering if the grandfathers' old roer had sent the pebble through the Kaffir, which seemed unlikely.

"My cousins traded the flesh of a springbok for cartridges, and the English went away up the spruit, while Claas got ready to cross at Truter's. But Vassell made delay; he said that hunger was rummaging his inside.

"'And that was the truth, Emanuel,' he told me later, 'for we had trekked since dawn. But it is not always needful to tell all the truth. Was I to arouse in Claas a greedy desire to share in the diamond? True,' said Vassell, 'we had agreed to share and share alike in the hunt, but the stone was not ivory, skin, nor meat, and I alone found it. We are commanded to agree with our adversary "in the way with him." And by halting in that place for the boiling of coffee there would be time to pray for direction. If the Almighty would have us trek back to the wounded Kaffir, it would be wise to turn before crossing at Truter's.'

"Of course my cousin Claas, when he heard of Vassell's hunger, felt hungry too, and the Kaffirs were told to prepare the meal. Meantime Vassell took his Bible from the wagon-box and fell on his knees. He expected the Lord would order him back to the Wolwe, and so it happened. But to induce Claas to obey the Lord's direction without understanding the whole thing was the trouble.

"Like an inspiration a familiar text came to Vassell's mind. 'Blessed are the merciful: for they shall obtain mercy.' He showed this to Claas as his reason for turning about. The text had a new meaning for Vassell. I tell you again he felt that he had been inspired to remember it. You have to bear that in mind, or you will not rightly understand how his brain was afterward affected.

"'But it would be foolishness to apply the text to a wild Kaffir four hours' trek back,' said Claas.

"'Nay, not if the Kaffir be subdued,' said Vassell.

"'He is more than subdued; he is dead,' said Claas.

"'Nay, he may not yet have perished,' said Vassell. But he felt sure the black was dead. And he felt equally sure he had been inspired to understand that he himself should obtain mercy in the shape of the diamond if he returned even as the good Samaritan to the Kaffir fallen by the way. Still Claas was stiff-necked, until Vassell opened the Book at Jeremiah iii. 12: 'Return, ... for I am merciful, saith the Lord.' He handed it to Claas without a word.

"Claas naturally supposed that Vassell had opened the Bible at random, as the doppers often do when they are seeking direction. And hence Claas saw in this text a clear leading back to the Wolwe. Yet he wished to rest and smoke tobacco for a long hour after eating. But Vassell was greatly inspired with texts that day. He pointed to I Samuel xx. 38: 'Jonathan cried after the lad, Make speed, haste, stay not.' Then he fell into such a groaning and sighing about it that Claas could not smoke in peace.

"'Anything is better than your rumblings,' said Claas, and so they hastened on the backward course. 'For,' as Vassell told me, 'I was in deep tribulation of fear lest the vultures might gulp down the diamond, or some beak strike it afar.'"

Here the huge old burgher sat up straighter and paused so unexpectedly that his sudden silence was startling. I imagined he listened to something far off in the stillness of the waning moon. Lieutenant Deschamps and the French Canadians sat indifferent, but I sprang up and put hands to my ears. Nothing could I hear but the occasional stamping of our horses, the walking hoofs of our vedettes by the river's bend, and the clinking of swift water over gravel.

"Did you hear something strange?" the patriarch asked me.

"Did you?" I asked.

"Is it likely that a great-grandfather's ears can hear better than a young man's?" he asked courteously.

"But you stopped to listen," I replied.

Then he shamed me by saying gently: "An old voice may need a little rest. But now I will go on:

"My cousins trekked back as fast as their oxen could walk. They found the Kaffir still squirming, and covering his eyes from the vultures. This went to Vassell's heart. He could not cut the diamond out of the living. And perhaps it was not in the man. Vassell drove away the vultures and examined the wound. Then his heart was lifted up exceedingly, for as he told me, 'fear had been heavy in me lest the diamond had gone clear through the Kaffir and been lost on the veldt. But now my fingers felt it under the flesh of his back. An inch more had sent it through. And it seemed so sure the pagan must die before morning that my conscience was clear against extracting the stone in haste.'

"This Wolwe Veldt was then Lion Veldt, and Vassell thought it prudent to carry the Kaffir into the night-laager, for lions bolt big chunks, and the diamond might be in one of them. Claas consented, and so the tame Kaffirs lugged the wild one into one of the ivory-wagons, and left him to die at his leisure.

"Late in the night Vassell, wakened by Claas snoring, felt a strong temptation. He might get up and knife out the stone unseen. 'But I put the temptation away,' he told me, 'for my movement might waken Claas, or the Kaffir might kick or groan under the knife, and my brother might spy on me. So I mercifully awaited the hour when the Lord would let the diamond come into my hands without Claas suspecting anything. Besides, it was against my conscience to cut the Kaffir up warm when it seemed so sure he would be cold before morning.'

"But next morning the Kaffir was neither dead nor alive. And my cousins were keen to see their wives and children. They must trek on. But Vassell could not leave the diamond. 'And to end the Kaffir's life was,' he told me, 'more than ever against my conscience. That first text, "Blessed are the merciful: for they shall obtain mercy," kept coming back ............
