"You may go back to work," Del Mar signed to the other men, who went on, leaving one short but athletic looking fellow with Del Mar and Elaine.

"Lock her up, Shorty," ordered Del Mar, "and bring the other prisoner to me down here."

None too gently the man forced Elaine up-stairs ahead of him.

In the attic, the tramp, pacing up and down, heard footsteps approach on the stairs and enter the next room.

Quickly he ran to the doorway and peered through the keyhole. There he could see Elaine and the small man enter. He locked the door to the hall, then quickly took a step toward the door into the tramp's room.

There was just time enough for the tramp to see his approach. He ran swiftly and softly over to the further corner and dropped down as if sound asleep. The key turned in the lock and the small man entered, careful to lock the door to Elaine's room. He moved over to where the tramp was feigning sleep.

"Get up," he growled, kicking him.

The tramp sat up, yawning and rubbing his eyes. "Come now, be reasonable," demanded the man. "Follow me."

He started toward the door into the hall. He never reached it. Scarcely was his hand on the k.n.o.b when the tramp seized him and dragged him to the floor. One hand on the man's throat and his knees on his chest, the tramp tore off the breathing mask and goggles. Already he had the man trussed up and gagged.

Quickly the tramp undressed the man and left him in his underclothes, still struggling to get loose, as he took Shorty's clothes, including the strange head-gear, and unlocked the door into the next room with the key he also took from him.

Elaine was pacing anxiously up and down the little room into which she had been thrown, greatly frightened.

Suddenly the door through which her captor had left opened hurriedly again. A most disreputable looking tramp entered and locked the door again. Elaine started back in fear.

He motioned to her to be quiet. "You'll never get out alive," he whispered, speaking rapidly and thickly, as though to disguise his voice. "Here--take these clothes. Do just as I say. Put them on. Put on the mask and goggles. Cover up your hair. It is your only chance."

He laid the clothes down and went out into the hallway. Outside he listened carefully at the head of the stairs and looked about expecting momentarily to be discovered.

Elaine understood only that suddenly a friend in need had appeared. She changed her clothes quickly, finding fortunately that they fitted her pretty well. By pulling the hat over her hair and the goggles over her eyes and tying on the breathing mask, she made a very presentable man.

Cautiously she pushed open the door into the hallway. There was the tramp. "What shall I do?" she asked.

"Don't talk," he whispered close to her ear. "Go out--and if you meet any one, just salute and walk past."

"Yes--yes, I understand," she nodded back, "and--thank you."

He gave her no time to say more, even if it had been safe, but turned and locked the door of her room.

Trying to keep the old stairway from creaking and betraying her, she went down. She managed to reach the lower hallway without seeing anybody or being discovered. Quietly she went to the door and out. She had not gone far when she met an armed man, the sentry, who had been concealed in the shrubbery.

"Who goes there?" he challenged.

Elaine did not betray herself by speaking, but merely saluted and pa.s.sed on as fast as she could without exciting further suspicion.

Nonplused, the man turned and watched her curiously as she moved away down the path.

"Where's HE going?" the sentry muttered, still staring.

Elaine in her eagerness was not looking as carefully where she was going as she was thinking about getting away in safety. Suddenly an overhanging branch of a tree caught her hat and before she knew it pulled it off her head. There was no concealing her golden hair now.

"Stop!" shouted the sentry.

Elaine did not pause, but dived into the bushes on the side of the path, just as the man fired and ran forward, still shouting for her to halt. She ran as fast as she could, pulling off the goggles and mask and looking back now and then in terror at her pursuer who was rapidly gaining on her.

Before she could catch herself she missed her footing and slipped over the edge of a gorge. Down she went, with a rush. It was unfortunate, dangerous, but, after all, it was the only thing that saved her, at least for the time. Half falling, half sliding, scratching herself and tearing her clothes, she descended.

The sentry checked himself just in time at the top of the gorge and leaned as far over the edge as he dared. He raised his gun again and fired. But Elaine's course was so hidden by the trees and so zigzag that he missed again. A moment he hesitated, then started and climbed down after her as fast as he could.

At the bottom of the hill she picked herself up and dashed again into the woods, the sentry still after her and gaining again.

At the same time, we who were still in the chase had circled about the country until we were very near where we started. Following the dogs over a rail fence, I drew up suddenly, hearing a scream.

There was Elaine, on foot, running as if her life depended on it. I needed no second glance. Behind her was a man with a rifle, almost overtaking her.

As luck would have it, the momentum of my horse carried me right at them. Careful to avoid Elaine, I rode square at the man, striking at him viciously with my riding crop before he knew what had struck him.

The fellow dropped, stunned. I leaped from my horse and ran to her, just as the rest of the hunt came up.

Eagerly questioning us, they gathered about.

Having waited until he was sure that Elaine had got away safely, the old tramp slowly and carefully followed down the stairs of the ruined hotel.

As he went down, he heard a shot from the woods. Could it be one of the sentries? He looked about keenly, hesitating just what to do.

In an instant, down below, he heard the scurry of footsteps from the improvised laboratory and shouts. He turned and stealthily ran up-stairs, just as the door opened.

The tramp had not been the only one who had been alarmed by the shot of the sentry.

Del Mar was talking again to the men when it rang out. "What's that?"

he exclaimed. "Another intruder?"

The men stared at him blankly, while Del Mar dashed for the door, followed by them all. In the hall he issued his orders quickly.

"Here, you fellows," he called dividing the men, "get outside and see what is doing. You other men follow me. I want you to see if everything's all right up above."

Meanwhile the tramp had gained the upper hallway and dashed past the room which he occupied. Outside, in the hall, Del Mar and his men rushed up to the door of the room in which Elaine had been thrown. It was locked and they broke in. She was gone!

On into the next room they dashed, bearing down this door also. There was Shorty, trussed up in his underclothes. They hastened to release him.

"Where are they--where's the tramp?" demanded Del Mar angrily.

"I think I heard some one on the roof," replied Shorty weakly. He was right. The tramp had managed to get through a scuttle on the roof. Then he climbed down to the edge and began to let himself hand over hand down the lightning rod.

Reaching the ground safely, he scurried about to the back of the building. There, tied, was the horse which Del Mar had ridden to the hunt. He untied it, mounted and dashed off down the path through the woods, taking the shortest cut in the direction of Fort Dale.

Dusty and flecked with foam, the tramp and his mount, a strange combination, were instantly challenged by the sentry at the Fort.

"I must see Lieutenant Woodward immediately," urged the tramp.
