Best of all, Jack considered, was the fact that they had engaged the services of a skillful guide in the person of Arturus. He knew every foot of the ground, for most of his life had been spent on the Gallipoli Peninsula. Consequently they would have the advantage of being led around certain gullies that might have proved barriers or traps to anyone unacquainted with the vicinity.

Jack had amused himself during the afternoon in seeking a position that was a little elevated, where he could get something of a view of the territory beyond. Here, with the aid of his binoculars, he had tried to figure out what might be the easiest way of advancing.

When, soon after they had departed from the camp, he found that the guide was beginning to turn toward the edge of the water, Jack was not much surprised. Indeed, he had wondered why this might not prove the easiest method of covering the space separating the two camps.

Upon mentioning his belief to Arturus, Jack had learned that part of the trail did lead along the sandy stretch that hugged the shore. The only trouble was that some of the Turks were in the habit of coming down to the water during the night, and this being the case they were likely to stumble upon the enemy at any minute.

A sharp lookout was necessary to prevent discovery. No matter how lonely their surroundings might seem they must not be off their guard. Amos had been duly impressed with the fact that silence was golden in this case, and all comments he might feel inclined to make would have to be left until another time.

Presently they could hear the sound of the waves running up on the sandy beach. It chanced to be an unusually quiet night. Even out on the deep water there seemed to be nothing doing, though far away the boys could catch the flitting gleam of searchlights playing at tag with the darkness, as the vessels of the fleet stood guard.

Had the wind chosen to rise and rattle the leaves of the stumpy trees, as well as dash the rollers against the shore with more or less of a resounding clamor, it would have served their purpose much better. Still, they had to take conditions as they found them, and make the best of it.

Every rod placed behind them counted. Arturus had assured them it was not more than a mile and a half at the most which they had to cover before reaching the vicinity of the other camp.

Now a distance like that may seem a mere trifle when the road is good, and the traveler has daylight to show him what obstacles he must surmount. When he finds it necessary to grope his way along over the roughest of ground, avoiding many threatening pitfalls, listening constantly for signs of lurking foes, and meeting with every conceivable manner of trouble, the case becomes a more serious one.

Amos had started with a light heart. He fancied they would certainly be able to tide over the gap inside of an hour or two. Looking back he could remember several instances when he and Jack had done such a caper as this without exerting themselves unduly. He therefore felt that before the end came they would surprise the guide with the abundance of their knowledge concerning Indian ways. Darkness had little terror for Amos at starting time.
