"M'yes," admitted the Lieutenant-Commander grudgingly. "But here we are without being able to let rip at even the most tempting target. If there had been time to slip down to Tenedos and get a fresh supply of torpedoes from our parentship I wouldn't mind in the least. As it is, we've to mark time for the next three days." "Might I make a suggestion, sir?" asked Dick. "By all means," replied Huxtable. The two officers were alone on the after platform of the little craft. The rest of the officers, having been on deck for some time, were down below. Most of the crew were "standing easy" on the limited expanse of fore deck--the narrow platform extending from the base of the conning-tower to within ten feet of the snub bows. "If we make for Prince's Island again," suggested Dick, "we could keep that tower under observation. There are some of our men imprisoned in it, and the place appears to be slenderly guarded." "Dash it all, man!" ejaculated Huxtable; "surely you don't suggest that a submarine should bombard a fort? That, apparently, is the crux of your proposition." "Not necessarily," replied the Sub. "If it came to the point, our guns would make small beer of the Turkish garrison. But if you would let me have half a dozen men, sir, I'd take Farnworth with me, and make a night attack upon the place. We ought to be able to rescue the prisoners and back on board within half an hour, with very little risk." "What would happen if, during that half-hour, a couple of Turkish destroyers put in an appearance?" asked Huxtable. "I am inclined to let you tackle the job; but one must weigh the matter carefully. I don't want to lose half a dozen hands, nor do I want to leave Farnworth and you marooned on Prince's Island. That's what it would mean, you know." Dick did not reply. His mind was set upon the sight of that forlorn party of bluejackets being haled into captivity. Perhaps they might be--but no, the possibility was too remote. "We'll do what we can," declared Huxtable, who rapidly warming to the plan. "At any rate, it will be occupying our time. Let's go below and have a look at the chart. Mr. Devereux," he called out, "pass the word for all hands to bathe, and then a quarter of an hour's 'stand easy' for the men to smoke." Eagerly the crew took advantage of the permission, and the immediate vicinity of the submarine soon dotted with the heads of the swimmers as they revelled in the clear waters of the Sea of Marmora. Bedding and blankets were also brought on deck to air while the diminutive "ship's company" were enjoying their pipes and cigarettes. At two bells in the second dog-watch the submarine cleared for running on the surface. Devereux was in charge, the Lieutenant-Commander having taken the opportunity of snatching a few hours' sleep. At eleven knots she steamed leisurely towards the yet invisible island, for as the sun sank low in the west a slight mist obscured the horizon.
