Hal gave General Givet the letter, and stood at attention. The general read in silence. Then he turned to Hal.

"All right," he said briefly, signifying that Hal might go.

"But, general," said the lad, "I was ordered to bring back your answer."

The general looked at him in surprise.

"Do you mean you intend to go back to-night?" he demanded.

"I thought I would start along about midnight," replied Hal. "I would sleep until that time."

The general was silent for some moments, musing.

"You are a brave lad," he said, at last. "I had figured on sending my answer by another courier; but perhaps your plan is better. You may report to me at midnight, and I shall have the answer ready."

Hal saluted and turned to leave the hut.

"Wait a minute," commanded the general. "Tell me something of yourself.

How comes it that you, an American, I take it, have been selected for such perilous work? Why, you cannot be more than eighteen years old."

"Seventeen, general," replied Hal, with a smile; and then he told the Belgian officer of his experiences since leaving Berlin.

The old general was amazed.

"Remarkable! remarkable!" he repeated, time after time.

Finally he called an officer, and commanded that the latter find Hal a place to sleep.

"Remember, midnight," called the general, as Hal was leaving the hut.

Hal saluted again.

"Yes, general," he replied, and followed the young officer.

Promptly at midnight Hal, greatly refreshed by a sound sleep and hearty meal, once more entered the general's quarters and came to attention.

"The answer you are to carry back is simply: 'I shall act upon your plan,'" said General Givet. "Good luck to you on your journey, and I have only one command: Make all possible haste."

Hal saluted and set out on his return, journey to Liege.

It was early morning when he came once more to the farmhouse where he had fought so n.o.bly the day before. His fear for Chester's safety increased as he approached, and it was not without some misgiving that he ascended the porch steps and knocked softly at the door.

He heard a light footstep within, the door swung open, and Edna peered forth at him.

"What! Back so soon?" she exclaimed gladly.

"Yes, I made pretty good time. How is Chester?"

Hal's doubts were soon set at rest.

"He is much better this morning than could have been expected," replied the girl. "He ate a hearty breakfast, and says he is feeling fine."

Hal followed her up the steps to where Chester lay, impatiently awaiting his coming. Edna went downstairs to see about getting him something to eat.

"Will you be able to leave to-day?" asked Hal, of Chester.

"I am ready to go right now. I am still weak, but I am sure I can make it all right. I'm bandaged up fine."

"You are sure you are feeling fit?"

"Certainly. Besides, I don't want to be left behind again. You are having all the fun. I want to get in on a little of it myself."

And so it was arranged that the boys should leave immediately after luncheon. They sought long and earnestly during the morning to prevail upon Edna to accompany them, or to make her way to Louvain; but she declared her intention of remaining where she was.

"I am much safer here than I should be on the road," she said. "No one will harm me. Besides, I must take care of the house."

Unable to shake her determination, the boys gave up the attempt, and for the rest of the morning the three chatted pleasantly.

Luncheon over, the boys immediately prepared to fare forth again. Edna accompanied them to the bottom of the steps, where they said good-by.

"Come and see me again," she urged, as they shook hands with her. "You are always welcome here."

"We certainly shall," cried both lads together, as they started upon their way.

Chester was still weak, but he walked along wonderfully well, considering the nature of his wound. Still, it was plain to Hal that every step cost him an effort, and their progress was necessarily slow.

All afternoon they plodded onward without encountering the enemy, and soon after nightfall came upon the place where the Belgian outposts had been stationed the night before. The signs of a struggle were plainly evident.

"There has been a battle here," remarked Hal, after inspecting the ground.

"There is no doubt about that," returned Chester, "and the Belgians have been driven back. We shall have to be careful."

They were proceeding on their way more cautiously than before, when from ahead there suddenly came the sound of trampling hoofs.

"A Belgian reconnoitering party, I guess," said Hal. "We are safe enough now."

Presently a body of hors.e.m.e.n came into view. The lads continued toward them, and the hors.e.m.e.n were but a few yards away, when Chester cried suddenly:

"They're Germans!"

It was true. It was a squadron of Uhlans, returning from a reconnaissance of the Belgian position.

It was too late for the boys to run. The cavalry was upon them. The lads stepped to the side of the road, and continued on their way apparently unconcerned. A German officer stopped them.

"Who are you?" he demanded. "What are you doing here?"

"We are American boys," replied Hal, "and are making our way to Liege."

"Well, you won't get to Liege to-night. Turn about and march the other way."
