The Arab hesitated for a brief moment. Then perhaps it occurred to him that his situation could scarcely be worse than it was; perhaps he was mutually attracted to this young man of his own age. At any rate, after the slightest pause, he said, raising his hand:

"By the beard of the Prophet I swear it."

During this conversation the two men had remained behind the wall, Burnet every now and then peering through a gap in the masonry in the direction from which the Arab had come. He now suggested that Rejeb should go to the corner and keep watch for the pursuers. Having left his field glasses with the rest of his equipment in the underground room, he was less able than the keener-sighted Arab to view the distant country.

Rejeb went to the corner and flattened himself against the wall with the instinct for cover natural to a dweller in the wilds. In a few moments he beckoned to Burnet with one hand, the rest of his body remaining motionless. When Burnet joined him, he asked him to look at a large bed of rushes some distance to the north-west. Shading his eyes with his hand, and careful not to expose himself, Burnet gazed towards the spot indicated, and was soon able to make out five or six figures moving among the reeds and advancing straight towards the tell. Burnet led the Arab to the central ruins and through the porch to the entrance of the underground room. Raising the slab they descended; then Burnet mounted into the interior of the colossal animal in which he had left his broom, and swept sand over the slab and the nearest footprints as before. He had hardly withdrawn the broom when he heard shuffling footsteps on the rough ground beyond the wall, and looked out through the wide mouth of the image. It was almost completely dark within, and in the unlikely event of any enquirer thinking to peer into the jaws of the colossus he could escape discovery by stooping.

In a few minutes a tall Arab appeared round the corner of the wall. He was followed at short intervals by four others. All were stalwart sinewy warriors of the desert, bristling with arms. They hunted through the ruins like a pack of dogs that have lost the scent. Here one would point to the impressions of sandals, and the rest followed him as he traced them along the wall and up to the portico. Burnet watched them without much anxiety, for he had taken care that no tell-tale footmarks remained around the slab; and knowing that the tracks that were visible led both towards and away from the ruins, he guessed that the Arabs would suppose that their quarry had come and returned. Their actions justified him. They traced the marks back to the wall, then back again to the portico, beneath which they stood to consult together. From the few words that Burnet caught it was clear that they had seen Rejeb mount the tell, and they supposed that he had crossed it and pursued his journey on the other side. Presently one of them climbed a pile of rubbish from which he could scan the surrounding country. The fugitive could not have gone any great distance, and he must become visible on one or other of the open spaces between the beds of rushes. The scout's four companions meanwhile threw themselves down in the shade of the portico to rest.

Secure in his hiding-place, Burnet felt some amusement at the situation. He went down to the chamber beneath, and, warning Rejeb against making any sound, took him up to his peep-hole and showed him the figure of his enemy looking for him. It was some time before the Arab gave up his vain task and returned to his companions. They came to the conclusion that the fugitive must be lying hidden among the rushes near the tell, and separating, started to scour the vicinity thoroughly. They went methodically through clump after clump until Burnet grew tired of watching them. Not until it was getting late in the afternoon did their perseverance give out. Baffled, weary, and angry at their failure, they rested awhile on the tell and ate some of the food they had brought with them; then they set off to return the way they had come.

Burnet was glad enough to win release at last from his stuffy quarters. Emerging with Rejeb, he made all secure, and prepared to resume the mission which the day's events had interrupted. In the underground chamber he had already returned the young Arab's arms, and discussed with him his subsequent movements. Rejeb would continue his journey to his people, who were a march away to the south-east. He was full of gratitude to his rescuer, and begged to know how he might serve him.

"Surely it is right that I should serve the saviour of my life," he said; "and my people also: they shall know that in serving him they serve me."

"We will not talk of service now," replied Burnet. "Who can tell the future?"

"At least let me know the name of my preserver: how else can I speak of him rightly to my people, and bid them watch for opportunities of serving him?"
