Then, taking a course almost at right angles to the road, the fugitives were soon deep in a scrub-covered expanse of undulating ground.
"A good start," ejaculated Dick breathlessly. "By the time they've discovered their mistake over those two German officers and have explained matters to the Turks, we ought to be well on our way to Kum Kale."
"Twenty-four hours, they said, before the submarine puts to sea, sir," remarked Farnworth. "We ought to do it well before that time."
"I hope so," added the Sub. "By Jove! It will be a serious matter if we don't."
Once more night was drawing on apace, yet, in their ardour to warn their comrades of an unexpected peril, they gave no thought to fatigue. Guided by the stars, the Sub shaped a course which he reckoned would bring them within the district supposed to be held by the French Expeditionary Force. By daylight they should be well within sight of Kum Kale.
"Steady!" cautioned Dick, as they commenced to descend a steep declivity. "I fancy we're close to the sea again."
"I certainly can hear surf," declared the midshipman.
"So much the better unless the coast is very much indented," added the Sub. "We can't be so very far from Yenikeui."
"Hope the Turks aren't there in force, like they were last time, sir."
"Not much fear of that. More than likely we'll stumble across a French outpost."
