He bit his tongue trying to repress the exclamation that leaped to his lips, but he succeeded, although his fingers were badly blistered.

Little by little, with many pauses, they reached the edge of a small section of the first trench. Nothing hindered them, no one challenged them. In fact their progress was so free from obstacles that the corporal, a wily veteran who had had long experience among the savage Moros while serving in the Philippines, became uneasy, fearing an ambush.

Still, that was one of the chances that the party had to take, and there was nothing to do but to keep on. But they redoubled their precautions, every sense tingling with watchfulness against a sudden surprise.

They worked their way along the trench until they reached the entrance. No sound came from the interior. They listened for the murmur of conversation, the scraping of feet, the clank of a weapon. They looked down its length for a ray of light. Not a gleam or a sound rewarded them.

As far as they could judge, it was absolutely deserted. But on the other hand it might be bristling with armed men, waiting in a stillness as deathlike as their own the command to fire.

For fully ten minutes their watch continued. Then the corporal gathered them close around him and gave his commands in a whisper.

"We'll raid it," he decided. "There are only a few of us, but we'll have the advantage of surprise. That is, if they're not waiting to surprise us. But we'll have to gamble on that. It's only a connecting trench, and there won't be more than a dozen men or thereabouts in it. If we could bag them and take them back to camp it would be a good night's work. Have your guns ready and be prepared to slip them a few grenades if we have to. I'll lead the way and when the time comes I'll flash my light. Come along now and be right on your toes when I give the word."

Corporal Wilson went first and his scouting party followed close on his heels. It was like going into the jaws of death. It would have taken less nerve to face a charge, for then their blood would have been up and they would have been fired by the sight of their enemy. There would have been nothing of this eerie stillness, this vault-like chill. Yet not one of them hesitated or lagged behind.

Twenty paces had been covered when the corporal stopped, drew out his flashlight and sent out a stream of radiance that illumined every nook and cranny of the trench.

On the instant the boys had their rifles at their shoulders with their fingers on the triggers, ready for a volley.
