At length he stopped, placed his right hand to his forehead, and looked around.

"What have I been saying?" he asked in a calmer voice. "It seems to me that I have been in a strange country seeing all kinds of things."

"You are all right now," Jasper replied. "You certainly have been raving at a great rate."

"Have I?" the old man queried, and he lapsed into a momentary silence.

"Peculiar feelings come over me at times. The fresh air of night has done me much good. I shall walk a short way with you along the road."

David was now a pleasant companion, and Jasper enjoyed talking to him.

He enquired about the progress of the work at the falls and asked numerous questions. Not once did he refer to the dark forebodings which had possessed him at the Haven, and Jasper believed that he had forgotten about them.

"I think I shall return now," he said after they had walked some distance.

"Shall I go back with you?" Jasper asked.

"Not at all. I shall enjoy the walk alone. You are tired and should get home at once. So, good night. I hope to see you again soon."

Jasper stood and watched him until the darkness swallowed him up. Then he made his way along the road to his own lonely house. He was very tired, but he found it difficult to get to sleep. The strange words which David had uttered kept running constantly through his mind. When he did at last fall into a fitful slumber, he was beset by a dreadful monster, which was slowly crushing him to pieces while he was unable to do anything to save himself.

He was aroused from this nightmare by a loud pounding upon the door.

At first he imagined it was some one coming to his relief. Half dazed he groped his way across the room, threw open the door and peered out into the night.

"Who's there?" he demanded.

"It's only me," came a voice which he recognised at once as Betty's.

"Oh, Mr. Jasper, have you seen Mr. David?" she asked.

"Seen Mr. David!" Jasper exclaimed in surprise. "I haven't seen him since I left him last night on the road near the Haven. Didn't he go home?"

"No, he didn't, and that's the reason I'm here. I waited up for him and when he didn't come back, I started out to find him."

"You stay there a minute," Jasper ordered, as he closed the door and turned back into the room. Lighting a lamp, he was astonished to find that it was near midnight. It took him but a few moments to dress, and then he again threw open the door and stepped out into the night.

CHAPTER XXV

MYSTERY

By the light streaming through the doorway Jasper could see that Betty's face was very pale. She was greatly agitated as well, and her teeth chattered as she spoke.

"You have been running hard," Jasper remarked. "You had better come in and rest awhile."

"No, no," the girl protested. "Don't let us wait a minute. We must find Mr. David!"

"Are you sure he isn't home?" Jasper asked.

"Yes, I am sure he isn't there."

"But he may have slipped in and you didn't hear him."

"No, no, he couldn't have done it. I was listening and watching every minute for him to come back. I am certain I would have seen him."

"Does Mrs. Peterson know where you are?"

"No. She was asleep when I left. I only intended, to come a short distance for I was sure that I would meet Mr. David coming back. But when I didn't, I came all the way here. Oh, let us go at once."

Jasper stepped back into the room, and put out the light. He was about to close the door when he paused.

"Wait a minute," he said, "until I get my lantern. We can't do anything without a light. Mr. David may have fainted by the side of the road. He is an old man, you know."

It did not take Jasper long to get the lantern, and soon they were speeding across the field toward the main highway. He noticed that Betty kept very close to him, and as they drew near the Haven she seemed to be trembling violently. She started often, and Jasper wondered what was the matter with her.

"Were you not frightened to come all the way alone?" he asked.

"Not at first," was the reply. "But I was frightened after a while and I ran hard."

"What frightened you? Were you afraid of the dark?"

"No--yes," Betty faltered. Jasper wondered at her answer, but made no comment.

All along the road they watched most carefully, thinking they might find David. Especially careful was this search as they neared the Haven but not a trace of him could they find.

The Petersons were greatly concerned over the missing man. The captain suggested that the neighbours should be notified and a search-party should start out at once. As this seemed the only thing to do, Jasper hurried to the village and aroused Andy Forbes from his slumbers. It took the storekeeper several minutes to grasp the significance of the affair, and Jasper had to do considerable explaining.

"So you tell me that Crazy David is lost?" he at length queried.

"Certainly. Isn't that what I have been trying to tell you? We must get a search-party out after him at once. I fear that evil has befallen the old man. He may be wandering off in the woods somewhere, as his mind seems to be uncertain at times."

"I'm afraid we can't do much to-night," and Andy scratched his head in perplexity. "However, I'll see what I can do. Maybe I can get a bunch of men together before morning."

"That's good," Jasper encouraged. "You round up the men here, and I'll go to the camp down the road. There are several men there and I'll get one of them to hurry to the falls and bring in all the men. I feel responsible for the welfare of David as I had strict instructions to look after him. If anything has befallen him I shall never forgive myself."

It took Jasper over an hour to go to the camp and bring back a half dozen men. In the meantime a dozen or more had left the village with lanterns to begin the search. These he met up the road. They had searched every nook and corner, but had found no trace of the missing one.

"It's no use hunting when it is so dark," Andy informed him. "We might as well look for a needle in a hay-stack. I move that we wait until morning."

This suggestion was carried out, and while most of the men went back to their homes in order to get something to eat, Jasper made his way to the Haven. Mrs. Peterson met him at the door and her face bore a worried expression.

"Have you found him?" she enquired. "We have been so uneasy."

"No," was the reply. "We must wait until morning. It is no use groping about in the dark. Where is Betty?"

"She's in Mr. David's room. I am so anxious about her. She has been crying and wringing her hands ever since you left. I cannot tell what has come over the girl."

"She is fretting about David, no doubt."
