Late in the afternoon, he slipped away from the south of the island with the five Arabs, leading their horses through the swamp. Then they swept round to the west, outside the probable range of the enemy's scouts, and rode rapidly in the direction of the tell. When they came in sight of the ruins, lit up by the glow from the setting sun, Burnet confided the horses to the care of two of his men, and with the other three went forward on foot, taking advantage of what cover the barren country afforded. He hoped, before darkness closed upon the scene, to be able to discover, from the summit of the mound, whether the guns had been extricated from the bog; if there was no sign of them, it would be necessary to go farther north.

CHAPTER XV

A RAID

Burnet had only just reached his former observation post on the tell when, looking to the north, he saw two mounted men in khaki about two miles away riding slowly in his direction. A few minutes later there came into view the horses of the gun teams and the muzzles of the guns. Through the haze of dust cast up by the heavy vehicles it was impossible to see the escort, which was no doubt following.

It was clear that he had arrived only just in time. Half an hour later he would certainly have found the tell occupied. The day was already so far advanced that the Turks would probably camp on the tell for the night. He instantly decided on his course of action. The underground chamber was unknown to Burckhardt, the only man among the enemy who had previously visited the tell. Burnet resolved to take refuge there with his three Arabs, trusting to the chapter of accidents to give him later the opportunity he was seeking.

The Arabs were surprised when he lifted the slab and disclosed the cellar below, and their excitement was almost boyish as he climbed up into the colossal figure with his brush of reeds. Watching him smooth the sand over the slab they yielded to a burst of amusement: Burnet had never seen the customary gravity of the Arab so much impaired.

From his spy hole at the mouth of the animal Burnet kept watch for the coming of the enemy. Within ten minutes the two troopers came into sight. Immediately behind them now were two officers, in one of whom he recognised Major Burckhardt. And he could now see, not far in the rear of the two guns, a half squadron of cavalry, together with a number of men on foot, driving mules laden with boxes and large bundles, which contained no doubt ammunition and the impedimenta of a camp.

Burnet watched the approach of this force with some anxiety. Would they halt at the tell, or, late as the hour was, continue their march to Rejeb's stronghold? He had only a limited range of vision from inside the colossus, and as the head of the column passed out of sight he feared that there was no intention of bivouacking, and his only chance of interfering with the guns would be lost.

Presently, however, he heard voices very near, and round the angle of the wall came Major Burckhardt, toddling along on foot, accompanied by a Turkish officer whom Burnet surmised to be the commander of the gunners. They came to a stand on the open space in front of the colossus, and Burckhardt, lifting his hand with the gesture of a showman, said:
