"But, Monsieur, it is still too hot to travel. Look! No one is stirring.

All the village is asleep."

He waved his enormous hand, with henna-tinted nails, towards the distant town, carved surely out of one huge piece of bronze.

"Untie the horses. There are gazelle in the plain near Mogar. Didn't you tell me?"

"Yes, Monsieur, but--"

"We'll get there early and go out after them at sunset. Now, Domini."

They rode away in the burning heat of the noon towards the southwest across the vast plains of grey sand, followed at a short distance by Batouch and Ali.

"Monsieur is mad to start in the noon," grumbled Batouch. "But Monsieur is not like Madame. He may live in the desert till he is old and his hair is grey as the sand, but he will never be an Arab in his heart."

"Why, Batouch-ben-Brahim?"

"He cannot rest. To Madame the desert gives its calm, but to Monsieur--"

He did not finish his sentence. In front Domini and Androvsky had put their horses to a gallop. The sand flew up in a thin cloud around them.

"Nom d'un chien!" said Batouch, who, in unpoetical moments, occasionally indulged in the expletives of the French infidels who were his country's rulers. "What is there in the mind of Monsieur which makes him ride as if he fled from an enemy?"

"I know not, but he goes like a hare before the sloughi, Batouch-ben Brahim," answered Ali, gravely.

Then they sent their horses on in chase of the cloud of sand towards the southwest.

About four in the afternoon they reached the camp at Mogar.

As they rode in slowly, for their horses were tired and streaming with heat after their long canter across the sands, both Domini and Androvsky were struck by the novelty of this halting-place, which was quite unlike anything they had yet seen. The ground rose gently but continuously for a considerable time before they saw in the distance the pitched tents with the dark forms of the camels and mules. Here they were out of the sands, and upon hard, sterile soil covered with small stones embedded in the earth. Beyond the tents they could see nothing but the sky, which was now covered with small, ribbed grey clouds, sad-coloured and autumnal, and a lonely tower built of stone, which rose from the waste at about two hundred yards from the tents to the east. Although they could see so little, however, they were impressed with a sensation that they were on the edge of some vast vision, of some grandiose effect of Nature, that would bring to them a new and astonishing knowledge of the desert. Perhaps it was the sight of the distant tower pointing to the grey clouds that stirred in them this almost excited feeling of expectation.

"It is like a watch-tower," Domini said, pointing with her whip. "But who could live in such a place, far from any oasis?"

"And what can it overlook?" said Androvsky. "This is the nearest horizon line we have seen since we came into the desert."

"Yes, but----"

She glanced at him as they put their horses into a gentle canter. Then she added:

"You, too, feel that we are coming to something tremendous, don't you?"

Her horse whinnied shrilly. Domini stroked his foam-flecked neck with her hand.

"Abou is as full of antic.i.p.ation as we are," she said. Androvsky was looking towards the tower.

"That was built for French soldiers," he said. A moment afterwards he added:

"I wonder why Batouch chose this place for us to camp in?"

There was a faint sound as of irritation in his voice.

"Perhaps we shall know in a minute," Domini answered. They cantered on.

Their horses' hoofs rang with a hard sound on the stony ground.

"It's inhospitable here," Androvsky said. She looked at him in surprise.

"I never knew you to take a dislike to any halting-place before," she said. "What's the matter, Boris?"

He smiled at her, but almost immediately his face was clouded by the shadow of a gloom that seemed to respond to the gloom of the sky. And he fixed his eyes again upon the tower.

"I like a far horizon," he answered. "And there's no sun to-day."

"I suppose even in the desert we cannot have it always," she said. And in her voice, too, there was a touch of melancholy, as if she had caught his mood. A minute later she added:

"I feel exactly as if I were on a hill top and were coming to a view of the sea."

Almost as she spoke they cantered in among the tents of the attendants, and reined in their horses at the edge of a slope that was almost a precipice. Then they sat still in their saddles, gazing.

They had been living for weeks in the midst of vastness, and had become accustomed to see stretched out around them immense tracts of land melting away into far blue distances, but this view from Mogar made them catch their breath and stiffed their pulses.

It was gigantic. There was even something unnatural in its appearance of immensity, as if it were, perhaps, deceptive, and existed in their vision of it only. So, surely, might look a plain to one who had taken haschish, which enlarges, makes monstrous and threateningly terrific.

Domini had a feeling that no human eyes could really see such infinite tracts of land and water as those she seemed to be seeing at this moment. For there was water here, in the midst of the desert. Infinite expanses of sea met infinite plains of snow. Or so it seemed to both of them. And the sea was grey and calm as a winter sea, breathing its plaint along a winter land. From it, here and there, rose islets whose low cliffs were a deep red like the red of sandstone, a sad colour that suggests tragedy, islets that looked desolate, and as if no life had ever been upon them, or could be. Back from the snowy plains stretched sand dunes of the palest primrose colour, sand dunes innumerable, myriads and myriads of them, rising and falling, rising and falling, till they were lost in the grey distance of this silent world. In the foreground, at their horses' feet, wound from the hill summit a broad track faintly marked in the deep sand, and flanked by huge dunes shaped, by the action of the winds, into grotesque semblances of monsters, leviathans, beasts with prodigious humps, sphinxes, whales. This track was presently lost in the blanched plains. Far away, immeasurably far, sea and snow blended and faded into the cloudy grey. Above the near dunes two desert eagles were slowly wheeling in a weary flight, occasionally sinking towards the sand, then rising again towards the clouds. And the track was strewn with the bleached bones of camels that had perished, or that had been slaughtered, on some long desert march.

To the left of them the solitary tower commanded this terrific vision of desolation, seemed to watch it steadily, yet furtively, with its tiny loophole eyes.

"We have come into winter," Domini murmured.

She looked at the white of the camels' bones, of the plains, at the grey white of the sky, at the yellow pallor of the dunes.

"How wonderful! How terrible!" she said.

She drew her horse to one side, a little nearer to Androvsky's.

"Does the Russian in you greet this land?" she asked him.

He did not reply. He seemed to be held in thrall by the sad immensity before them.

"I realise here what it must be to die in the desert, to be killed by it--by hunger, by thirst in it," she said presently, speaking, as if to herself, and looking out over the mirage sea, the mirage snow. "This is the first time I have really felt the terror of the desert."

Her horse drooped its head till its nose nearly touched the earth, and shook itself in a long shiver. She shivered too, as if constrained to echo an animal's distress.

"Things have died here," Androvsky said, speaking at last in a low voice and pointing with his long-lashed whip towards the camels' skeletons.

"Come, Domini, the horses are tired."

He cast another glance at the tower, and they dismounted by their tent, which was pitched at the very edge of the steep slope that sank down to the beast-like shapes of the near dunes.

An hour later Domini said to Androvsky:

"You won't go after gazelle this evening surely?"
