She would never have known that she had cried the words aloud but for the immediate answer that came in a casual, confident voice she seemed to have known all her life.

"All serene--don't worry."

Something loomed large and white below the brake, but the voice seemed to be on a level with her, and almost she fancied she could catch the gleam of his eyes in the enveloping darkness. She was too shaken with joy and relief to make any response, neither was there time, for Roper raging and profane arrived upon the scene.

"What the--? Who the--" came his infuriated voice.

"I've had a hard time catching you up," drawled the stranger. "Why, my good fellow, what kind of transport rider are you? You've lost the road! I wonder what Deary and Co. would say if they knew their goods were being battered and bundled all over the veld like this, miles off the track?"

The rage of the baffled Roper came down like a river in flood, a foul torrent of abuse in Dutch and Kaffir mingled with English. Fortunately, most of it was incomprehensible to Vivienne, but she was able to gather that the man on the horse, Deary and Co., the goods, and the veld, were all being consigned _en bloc_ to a place whose exact geographical position has never yet been officially defined.

The fire now burning brightly revealed the new-comer seated idly on a large white tailless horse, which in outline somewhat resembled a grey hound and whose lean sides were closely pitted with tiny blue spots as though it had at some past time suffered from smallpox. The rider in his shirt sleeves looked cool and careless as always, but the hair lying dank upon his forehead and the soapy foam upon his horse's flank told a tale which whoever ran might read. He now, with the subsidence of Roper's eloquence, contributed his favourite remark to the occasion.

"_That's_ all right."

"What the Billy-c.o.c.k-hat," (or words to that effect) "do you want, hey?"

demanded Roper.

"Just company. The pleasant time I spent with you last night gave me a taste for more. Then too I was sure you'd be glad of my a.s.sistance in finding your way back to the road to-morrow, without being obliged to lose several days in doubling on your tracks. Deary and Co. are particular friends of mine, and I know they'll be grateful for anything I can do in the way of speeding up their goods."

Some part of this information, or the nonchalance with which it was delivered gave Roper pause, and made him swallow any further observations he might have felt inclined to offer. He turned away muttering in savage tones something about his boys having "left the road" while he slept. The lie was an obvious one, but the stranger doubtless had his own reason for accepting it blandly and without comment. He now dismounted, unsaddled and knee-haltered his horse, and turned it to graze. Without taking further notice of Roper or anyone else, he proceeded to gather fuel from the neighbouring bush, and in a short time had a great fire of his own leaping in the gloom. He had built it some twenty yards or more from the waggons, but exactly facing Vivienne's watch tower, and by its rays she could see him foraging in his saddle-bags and preparing a meal. He made no attempt to communicate with her or amalgamate in any way with Roper's camp. She wondered a little at this, but had already learned to rely upon the certainty of his knowing what he was about, and having a good reason for his every action. Since the moment she heard the unexpected sound of his voice, a feeling of peace and security had invaded her. Her strung nerves were at rest, and menace had gone from the night with the knowledge that this man was of those who took the fate of others in his hands and that hers was for the moment in his keeping.

A drowsy weariness had followed upon the strain of the afternoon, and her inclination was to sleep, but the sight of her knight-errant taking his supper in a very natural and everyday manner made her wonder whether she ought not to do the same, not only for the sake of keeping up appearances, but to preserve her health in case of emergencies. So when an _umfan_ came as usual to tell her that the dinner was ready, she descended from the waggon, and strolling over to the packing-case took her place as though nothing in the world had happened.

But sitting opposite a face which wore baffled rage and spite printed on every line of it was not a pleasant experience, and she was glad to look past it sometimes to a figure lying full length, smoking peacefully by a fire. The man Kerry never once glanced their way, but Vivienne was curiously aware of his being on the alert for every sound and movement in the camp. She knew very well that he could hear her say to Roper that it would be a pleasant act of courtesy to send over a cup of coffee to the stranger who evidently had no kettle in which to make any, and Roper's surly response to the suggestion.

"Look here! Do you take me for a d.a.m.n-fool Samaritan?"

"No, indeed!" she retorted dryly. "But I thought that even you might be inclined to perform an act of common decency."

"Well, you thought wrong. I told you before that my waggon wasn't a hotel for lost, stolen, or strays, didn't I?"

Her only answer was to emphatically refuse the cup of coffee proffered her by an _umfan_. The rest of the meal was accomplished in silence.

Back in her tent once more, she composed herself for the night, revolver to hand, her face towards her friend. He had made another collection of fuel, and evidently meant to keep a big fire going all night. Something in the quiet way he had settled himself, half seated against his saddle, told her that he meant to keep watch.

Also, he had produced a book, and was leaning forward in the firelight ruffling its pages, and softly whistling to himself. A wave of pleasure tingled through the girl as she recognised the air for one she had known and loved all her life; that exquisite setting by Mendelssohn and Lizst to Heine's poem _On Wings of Song_. She was strangely thrilled to hear its dear familiar cadence in this wild spot. Like the twinkle of home-lights seen suddenly from afar by a lost wayfarer, it gladdened and put fresh courage into her heart. How strange it seemed that this shirt-sleeved man who seemed part and parcel of primitive Africa, whom she had looked upon as a sort of Boer, should know anything so exquisitely civilised as the "_Auf Flugeln des Gesanges_!" She lay listening dreamily, her mind putting Heine's words to the frail haunting air.

On wings of song, Belov'd One, Away I'll waft thee, to where I know in the plains of the Ganges A secret nook most fair.

There sleeps a rich blossoming garden, Calm in the still moonlight: The lotus flowers are awaiting Their dearest Sister to-night.

The violets laugh as they prattle, And gaze on the stars in their spheres; Odorous legends the roses breathe Low in each other's ears.

There bound, and stand shyly listening, The gentle timid gazelles; Afar, from the sacred river, The waves' deep murmur swells.

There under the palms reclining, We'll drink by the sacred stream Of love and rest in full measure, And blissful dreams will we dream.

_On Wings of Sleep_ it should have been called, she thought, for the whole thing was a dream that could only come in sleep. It occurred to her at last that the man Kerry thought so too, and meant his persistent though soft whistling as a hint to her to sleep while he kept watch. It seemed indeed the best thing she could do, so that later when he was tired out she in turn could keep guard. Already Roper had got down his blankets, and she knew by the lowered tones of the _umfans_ that he had retired under the waggon.

Wearied out by the various emotions of the day, it did not take her long to fall asleep, but several times during the night she awoke, prompted by a restless fear which even through her dreams vaguely disturbed her.

But always there was calm in the camp, and always the man Kerry sat intent on his little book. The storm clouds had gone by, and the sky, shroudy and mysterious as the blue veil of an Eastern woman, was hung with jewels that shed a misty luminance over the immense and silent land.

When she finally threw off sleep in the small hours before dawn it was to find Kerry still lying there on his elbow placidly smoking. His book was still in his hand, but he appeared to be reading the fire rather than it. Vivienne wondered how she could let him know that she was awake and able to take up the vigil, but with the _Wings of Song_ still haunting her memory she did not wonder long. Very softly she began to whistle the air. He stirred, and glanced towards the tent. She whistled delicately on, and saw a slow smile flicker for a moment across his impa.s.sive face. Then he closed his book and lowered his head to the saddle. He understood. She stopped whistling. He slept, and she vigilled until the stars turned white and the hand of Dawn pushed them back from sight, and in their place scattered red and golden roses across the skies.

Full morning brought new factors into the game. Two sinewy Bechuana boys came light-foot up the trail of broken trees and crushed ant-hills made by Roper's waggons, and approaching Kerry set down the heavy packages from their heads and gravely saluted him. An _indaba_ ensued, accompanied by an arm-wave or two at the track by which they had come, some soft clicking remarks, and a few low sighs. Kerry, his pipe in his teeth, listened reflectively, and at the end of the recital gave a brief order to each. One went away to the horse, the other proceeded to make a cooking fire and unpack one of the loads which obviously contained provisions.

Vivienne, who had been for a little morning walk, and now sat on a rock some distance away, saw Roper, much intrigued, watching the proceedings from under his waggon. When he could no longer contain his curiosity he slouched over to Kerry.

"What's all this? Whose boys are these?"

"Mine. Any objection to them?"

"Well!--What the Halifax?--How do you travel then? Where is your waggon?"

"I can't remember ever having mentioned a waggon," was the imperturbable answer.

That was the secret of it all then! He had no waggon. Only a horse and two native carriers. Vivienne to whom the whole conversation came clear on the morning air witnessed also Roper's stupified amazement.

"So you're just hanging on to me?" he snarled at last.

"I like pleasant company."

"To Jerusalem with you--well, _I_ don't!"

"It's a free country." Kerry's manner was unfailingly suave, but at this juncture he arose from the mound on which he was seated and made it clear that as far as he was concerned the conversation was closed.

There was nothing left for Roper but to return to his own business of making things as unpleasant as possible for everyone in his camp. All through that torrid day he prowled and swore around his waggons, furiously tinkering and greasing and patching up the injuries they had sustained during the forced _trek_, giving his boys no rest from labour and abuse. But never once did he come near Vivienne, nor throw her a glance. She sat in her tent most of the day, mending a hole in the knee of her knickerbockers or staring at the sunlit land about her.

Thus it was from day to day. The two parties _trekked_ and outspanned together as though they were one, yet after the first day never a word pa.s.sed between them. Kerry made no attempt to communicate with Vivienne. Roper never spoke to Kerry. Vivienne pa.s.sed her days unmolested by Roper.

The objectionable feature of the affair was Roper's offensive habit of airing in a loud voice at the night outspan his opinion of "loafers" and "hangers-on"--men who "followed like jackals the waggon of another man, having none of their own." Kerry might have been a stock or a stone for all the sign he gave of hearing any of these things. But Vivienne's cheek burned for him, and at times she felt a curious impatience that one who had taken upon himself the chivalrous affair of guarding her should be able to put up with such insults. She could not help thinking that since he was there for her protection a simple way out of an odious situation would be for him to say: "Look here; come over to my camp, and I'll take care of you, and let this fellow go to the deuce. Certainly you will have to rough it with me, but you have to rough it in any case with this lout." She would have gone like a bird from a cage. In fact, she could not understand how any chivalrous man could fail to see that it was the only dignified thing to do, especially when Roper began presently to be ironical to her on the subject of her condescension in staying in his camp. One evening he remarked to her rudely: "I wonder you don't go and take up your quarters with your pal the Pioneer, instead of housing in my tent."

She was furious that the Pioneer, smoking not twenty yards off, took no more notice than if he were deaf or a fish. It seemed to her that patience might go a little too far, and a chill disdain began to take root in her soul.

And then one day she realised that it was rather a good thing after all that he had not invited her to leave Roper's waggon to join his own unsheltered caravan. That was the day on which the heavy lowering heat broke at last in a storm such as she had never known in her life. When trees and iron rocks leaped in flame and fell under splitting flashes of lightning, thunder seemed to explode upwards from the bowels of the earth to meet an answering detonation in the heavens, and rain came down like grey straight rods of steel, battering the road into a liquid, quivering ma.s.s of mud.

At the first warning peal, Roper had drawn his waggons to a standstill, covered everything with great bucksails and retired under the shelter of one, while the boys took shelter under the other. Peering from ant-eaten holes in her bucksail, Vivienne could just distinguish through the heavy curtain of rain her rear-guard escort--the white horse with drooping head and drapery of mackintosh, and a tall figure sheltering to leewards of it. The carriers with the instinctive art of natives had found some cranny of shelter somewhere, but Kerry and his horse got the full brunt of the storm.

In less than an hour, it was all over. A turquoise sky burned overhead, vivid orange sunshine drew clouds of incense from tree and earth and rock. The quivering mud of the roadway was the only unsightly evidence of what had pa.s.sed--that and the drenched forms of a man and beast whom Roper mocked obliquely by calling up to Vivienne:

"Nice weather for jackals, hey? I've just been waiting for this! We'll have it every day now the wet season has set in."

The girl's heart sank. But it was to sink lower yet in the days that followed when Roper's words came true and the storm faithfully repeated itself. She began to wonder then whether she had not misjudged the Pioneer, and to realise that possibly his knowledge of the country and the climate had something to do with the regulation of his temper to Roper's sneers. It was clear at any rate that if she had left the waggon and sought refuge with him she, too, would have had to weather the blinding storms that came and went every day regularly as clockwork, always leaving the country fresh and fragrant as a rose. Except for the roads! The going grew heavier daily and in that at least triumph was not all on Roper's side, for while he was obliged to keep to the mora.s.s-like track or risk capsize, Kerry's horse could pick its way delicately between rocks and ant-holes at the roadside. After the first day or two of wet weather the native bearers disappeared, and Kerry's horse bore the weight of an extra bundle.

It was a despairing experience to watch man and horse half-drown every day, then dry in clouds of steam under the brilliant sunshine that followed, and Vivienne sickened of it. She knew, too, that however strong the man, such an experience could not go on indefinitely without affecting his health, and she trembled for the day when he would perhaps fall ill of fever or pneumonia. Fortunately that day never dawned. One morning just as the sun was bursting forth after a terrible downpour, and the bucksails were being removed from the waggons, the blare of a coach horn came sailing through the air and a sound of mules' hoofs flapping in the mud. Vivienne almost jumped out of her skin with joy at the sight of a mail-coach, empty of everything but the driver and a ma.s.s of mail-bags.

Within twenty minutes, she was stowed inside the cart tent, the white horse was switched on behind, and the drawn-up coach waited only on the convenience of Kerry who before he could take his place in the cart wished to change his soaking clothes for some he had dried overnight.

The bush being his only retiring-room he prepared to take his bundle thither, but first he stepped over and addressed a curt remark to Roper scowling beside his waggon.
