Profiting by the confusion caused by the fall of the bomb, and by the fact that the attention of the Turkish search-light was directed skywards, the two fugitives set the pole in position, engaging the hook in the coping-stone of the wall.

Hand over hand Farnworth climbed to the top, where he threw himself on the sandy soil until the Sub rejoined him. As he did so the second and third bombs dropped almost simultaneously, exploded—one close to a search-light in the wall, the other in the moat; the blast of the detonation sending a shower of stones and dust over the two prostrate figures.

The troops engaged in throwing up earthworks and digging trenches had promptly vanished on hearing the explosion of the first bomb. A few had delayed bolting to their burrows sufficiently long to draw the canvas screens over the deep narrow trenches. Here and there a shot rang out from the earthworks, but for the most part the Turks in that locality were restrained from firing lest the flashes should indicate the position of the trenches.

Dick led the way, purposely choosing a direction that would take the fugitives towards the mountainous interior. He knew that on their flight being discovered a strict search would be made along the shore; while on the other hand the Turks would not be likely to look for them in the interior. His idea was to make a circuitous detour, and regain the Allies' position in the vicinity of the French troops operating near Kum Kale. Already his eyes had marked a gap between the triple rows of trenches where it seemed possible to pass through the hostile lines.

Suddenly the ground gave way beneath the feet of the two officers. With futile efforts they grasped at the earth to save themselves, then, encompassed by a cloud of dust, they dropped headlong into a deep pit.

CHAPTER XI

A Modern Odyssey

Farnworth regained his feet with great agility and assisted Dick to rise. Feeling considerably shaken by his unexpected tumble, the Sub was temporarily winded. For the moment he imagined that his ankle had been sprained, and on placing his hand upon that part of his leg he made the discovery that it was bleeding freely.

"By Jove, sir!" whispered the midshipman, "we've had a narrow squeak. Look!"
