IN common walks of life to play the spy is an ignoble role; yet the work has to be done, and there must be men to do it. There always are such men--nervy fellows who swing themselves into the saddle when their commander lifts his hand, and ride a mad race, with Death at the horse's flank every mile of the way. They are the unknown heroes of every war.

It was with a full realization of the dangers confronting him that Will cantered away from the Union lines, his borrowed uniform under his arm. As soon as he had put the outposts behind him, he dismounted and exchanged the blue clothes for the gray. Life on the plains had bronzed his face. For aught his complexion could tell, the ardent Southern sun might have kissed it to its present hue. Then, if ever, his face was his fortune in good part; but there was, too, a stout heart under his jacket, and the light of confidence in his eyes.

The dawn had come up when he sighted the Confederate outposts. What lay beyond only time could reveal; but with a last reassuring touch of the papers in his pocket, he spurred his horse up to the first of the outlying sentinels. Promptly the customary challenge greeted him:

"Halt! Who goes there?"

"Friend."

"Dismount, friend! Advance and give the countersign!"

"Haven't the countersign," said Will, dropping from his horse, "but I have important information for General Forrest. Take me to him at once."

"Are you a Confederate soldier?"

"Not exactly. But I have some valuable news about the Yanks, I reckon. Better let me see the general."

"Thus far," he added to himself, "I have played the part. The combination of `Yank' and `I reckon' ought to establish me as a promising candidate for Confederate honors."

His story was not only plausible, but plainly and fairly told; but caution is a child of war, and the sentinel knew his business. The pseudo-Confederate was disarmed as a necessary preliminary, and marched between two guards to headquarters, many curious eyes (the camp being now astir) following the trio.

When Forrest heard the report, he ordered the prisoner brought before him. One glance at the general's handsome but harsh face, and the young man steeled his nerves for the encounter. There was no mercy in those cold, piercing eyes. This first duel of wits was the one to be most dreaded. Unless confidence were established, his after work must be done at a disadvantage.

The general's penetrating gaze searched the young face before him for several seconds.

"Well, sir," said he, "what do you want with me?"

Yankee-like, the reply was another question:

"You sent a man named Nat Golden into the Union lines, did you not, sir?"

"And if I did, what then?"

"He is an old friend of mine. He tried for the Union camp to verify information that he had received, but before he started he left certain papers with me in case he should be captured."

"Ah!" said Forrest, coldly. "And he was captured?"

"Yes, sir; but, as I happen to know, he wasn't hanged, for these weren't on him."

As he spoke, Will took from his pocket the papers he had obtained from Golden, and passed them over with the remark, "Golden asked me to take them to you."

General Forrest was familiar with the hapless Golden's handwriting, and the documents were manifestly genuine. His suspicion was not aroused.

"These are important papers," said he, when he had run his eye over them. "They contain valuable information, but we may not be able to use it, as we are about to change our location. Do you know what these papers contain?"

"Every word," was the truthful reply. "I studied them, so that in case they were destroyed you would still have the information from me."

"A wise thing to do," said Forrest, approvingly. "Are you a soldier?"

"I have not as yet joined the army, but I am pretty well acquainted with this section, and perhaps could serve you as a scout."

"Um!" said the general, looking the now easy-minded young man over. "You wear our uniform."

"It's Golden's," was the second truthful answer. "He left it with me when he put on the blue."

"And what is your name?"

"Frederick Williams."

Pretty near the truth. Only a final "s" and a rearrangement of his given names.

"Very well," said the general, ending the audience; "you may remain in camp. If I need you, I'll send for you."

He summoned an orderly, and bade him make the volunteer scout comfortable at the couriers' camp. Will breathed a sigh of relief as he followed at the orderly's heels. The ordeal was successfully passed. The rest was action.

Two days went by. In them Will picked up valuable information here and there, drew maps, and was prepared to depart at the first favorable opportunity. It was about time, he figured, that General Forrest found some scouting work for him. That was a passport beyond the lines, and he promised himself the outposts should see the cleanest pair of heels that ever left unwelcome society in the rear. But evidently scouting was a drug in the general's market, for the close of another day found Will impatiently awaiting orders in the couriers' quarters. This sort of inactivity was harder on the nerves than more tangible perils, and he about made up his mind that when he left camp it would be without orders, but with a hatful of bullets singing after him. And he was quite sure that his exit lay that way when, strolling past headquarters, he clapped eyes on the very last person that he expected or wished to see--Nat Golden.

And Nat was talking to an adjutant-general!

There were just two things to do, knock Golden on the head, or cut and run. Nat would not betray him knowingly, but unwittingly was certain to do so the moment General Forrest questioned him. There could be no choice between the two courses open; it was cut and run, and as a preliminary Will cut for his tent. First concealing his papers, he saddled his horse and rode toward the outposts with a serene countenance.
