So Carl succeeded only in getting a little nearer Lysander, without increasing at all the distance between him and the corporal. It was a state of affairs that required serious consideration. He lay dawn again, and pretended to be anxiously looking for the mouth of the cave, whilst watching and reflecting.

Just then occurred a circumstance which seemed almost providentially designed to favor the boy's strategy. Upon the ledge appeared two human figures, male and female, touched by the moonlight, and defined against the sky. They remained but a moment on the summit, then began to descend in the shadow of the ledge. Their movements were slow, uncertain, mysterious. Below the base of the rock they stood once more in the moonlight, and after appearing to consult together for a few seconds, disappeared behind the bushes where Carl had placed his imaginary cave.

If Sprowl had any doubts on the subject before, he was now entirely satisfied. He believed the forms to be those of Virginia and the schoolmaster; they had been out to enjoy solitude and sentiment in the moonlight; and now they were returning reluctantly to the cave.

"Wouldn't Gus be edified if he was in my place!" Lysander little thought that he was the one to be edified,—as he would certainly have been, to an amazing degree, had he known the truth. "But we'll spoil their fun in a few minutes!" he said to himself, as he crept back towards his former position.

As for Carl, it was he who had been most astonished by the phenomenon. No sooner had he invented a cave, than two phantoms made their appearance, and walked into it! The illusion was so perfect, that he himself was almost deceived by it. Only for an instant, however. Continuing to gaze, he had another glimpse of the apparitions, when, having merely passed behind the bushes, they came out beyond them, in the direction of the real cave, and were lost once more in shadow. Lysander, engaged in making his retrograde movement, did not notice this very important circumstance; and the corporal was too intently occupied in watching Carl to observe anything else.

The captain got behind the shelter of a cluster of thistles, and beckoned for the two to approach.

"Corporal," said he, "hurry back and tell Ropes to bring up his men. I'll wait here."

The corporal crawled off.

Carl heard the order, saw the movement, and felt thrilled to the heart's core with joy. He was now alone with the captain. And he was no longer unarmed. In creeping towards the thistles, he had laid his hand on a wonderful little stone. Somehow, his fingers had closed upon it. It was about the size of an apple, slightly flattened, rough, and heavy. "I thought," he said afterwards, "if anything vas to happen, that stone might be waluable." And so it proved. Lysander, considering that the cave was found, had become less suspicious. "These Dutch are stupid, and that's all," he thought.

"You vas going to shoot me," said Carl, with an honest laugh at the ludicrousness of the idea.
