"They did it to you, girl," was the reply. "Why should they do such a thing to me?"

"Because you are great, that is why. They all know of the wonderful thing you had in your head. Oh!" she suddenly exclaimed, stopping short in her tracks.

"What is the matter?" David asked.

"They have taken away my rock! Look, there are only little pieces of it left."

"They needed it, no doubt, for the works up there, Betty. You must not mind when it has been put to such good use."

Betty, nevertheless, felt badly, and for a while she ceased her chattering and walked along quietly by her companion's side. At length they came to a place where the road left the path and swung to the right.

"Isn't this nice!" Betty exclaimed. "Some of our dear old path is left, anyway, and we can follow it and forget that any changes have been made."

The path ran close to the brook and after they had followed this for several hundred yards through a growth of young birches and maples, they came to a clearing which had been made since they were last there.

Above them was the road, and on its lower side was a large pile of big poles ready to be rolled into the brook.

"I wonder what they left them there for?" David enquired.

"Oh, I know," Betty replied. "Mr. Jasper told us, don't you remember, that they left a lot of poles to be used along the brook. They must be the ones."

"So he did tell us that," the old man mused. "Your memory is better than mine. Suppose we sit down here and rest a while. That walk has tired me."

"There's a nice place right in front of that big stump close to the brook," and Betty pointed with her finger. "We can rest there and eat a part of our lunch."

When they had reached the place Betty began to unpack the basket.

First of all she spread down a white cloth, and then laid out the sandwiches and cake. Then she paused, and a look of dismay overspread her face.

"We forgot to bring anything to drink!" she exclaimed. "I had the milk all ready in the bottle and came away without it. What shall we do?"

"Oh, never mind," David replied. "We can drink some of this brook water, can we not?"

"No, it's nasty. It's too warm. I know," and she reached for two tin cups. "There's a nice cool spring just up the brook. I have often got water there. You keep off the flies from the food. I won't be a minute."

Leaving David, Betty hurried up along the edge of the brook until she reached the spring bubbling out of the bank. Filling the cups she made her way back as carefully as possible so as not to spill any of the water. She had just reached the edge of the clearing when a strange sound fell upon her ears. It startled her, and looking up, her face blanched with terror, for coming down the steep bank was one of the large poles which had been separated from its companions. It was only a few seconds in making the descent, but in that brief s.p.a.ce of time a world of thought crowded into Betty's excited brain. She saw David sitting right in the track of death, unconscious of impending doom.

Betty tried to shout, to rush forward to rescue him, but no words came from her lips, and her feet seemed glued to the ground. Rapidly the pole sped down the bank, and then just when but a score of feet from the helpless old man it struck the large stump in its onward sweep.

With a wild bound it leaped high and like a mighty catapult hurled itself through the air over David's head and fell with a terrific crash into the brook below.

At first a wild scream of terror escaped Betty's lips, followed instantly by a cry of joy as she rushed forward, seized the hand of the bewildered old man and led him to a place of safety near the edge of the forest. Then her strength deserted her, and she sank down upon the ground and wept like a child.

"Oh, Mr. David, Mr. David," she sobbed, "you were nearly killed. Oh, oh, oh! Wasn't it awful!"

"There, there, Betty, don't feel so badly," and David stroked her hair in a gentle manner. "I'm all right now, so why should you cry?"

"But I can't help it," the girl moaned. "I was sure you would be killed, and I could do nothing to save you."

"Strange," her companion mused, "what started that log just as I was sitting there. It must have been loose and ready to start at the least motion."

"Let us go home," and Betty rose suddenly to her feet. "I don't want to stay here any longer. The place is not like it used to be. I do not feel safe. There seems to be danger everywhere."

Hurrying as fast as possible across the open s.p.a.ce and casting apprehensive glances up the bank lest another pole should take a sudden notion to come down, they soon reached the woods beyond.

"There, I feel safer now," Betty panted. "Those poles can't touch us, anyway."

"I did want to see the falls," David replied, "and I am quite disappointed. But I do not feel able to try the trip again as it tires me too much."

"Suppose we ask Mr. Jasper to drive you there," Betty suggested. "I know he will be only too pleased to do it. Isn't it funny we didn't think of that before?"

"That is a good idea," David a.s.sented. "Maybe he will do it to-morrow.

But what's the matter, girl?" he demanded, looking with surprise upon Betty, who had suddenly stopped and was staring down upon the brook through an opening among the trees.

"Look," she whispered, pointing with her finger, "there is that artist sketching down below. He doesn't know we are here, so let us be as quiet as possible."

"Well, why should he startle you?" David enquired. "He is not troubling us. I'm not afraid of him. In fact, I feel inclined to go and have a talk with him."

"Don't, please don't," and the girl laid her right hand imploringly on his arm. "Let us go home at once, for I feel shaky all over."

"Very well, then," David a.s.sented. "But I wish you would get over your foolish notion about that man. He is merely a harmless artist who has come to this place to get some good pictures. Why can't you be sensible?"

CHAPTER XXIII

RESCUED

Jasper had charge of fixing the poles and stretching the wires for light and power between the city and the falls, as well as throughout the country wherever it was planned to extend them. Gangs of men were at work along the lines, and Jasper was kept busy moving from place to place giving instructions and supervising everything. The entire responsibility rested upon him, and he wished to prove worthy of the trust.

The afternoon when David and Betty were up the brook, Jasper remained closer than usual to Creekdale, where a number of men were working.

Opposite them a small island nestled out in the river, called "Emerald"

Island by reason of its rich covering of fir, pine and birch trees. As a rule, Jasper paid strict attention to his duties, but to-day his mind often wandered and he would stand gazing out over the water to the island beyond.

As the afternoon wore away he became quite restless and watched the river most anxiously. A wind had sprung up, which, gentle at first, increased steadily into a gale. The water soon became rough and great white-caps rolled up-stream, especially heavy where the tide was strongest.

At length, leaving his men he went to the sh.o.r.e and stood close to the watery edge. He looked more down the river than formerly, as if expecting some one from that direction. But occasionally he cast his eyes off toward the island and breathed more freely after each look.

He often consulted his watch as he now paced up and down the beach.

"What can be keeping that fellow?" he muttered. "He should have been here an hour ago. Surely he's not tied up on account of the wind. I gave him strict instructions to come back as soon as possible. If he does not----h.e.l.lo, there he is now," and his face brightened as he gave a sigh of relief.

Coming up the river was a big boat used for rafting purposes containing one man. Volumes of spray leaped high as she surged through the water driven by a seven horse-power engine. This craft was used for towing logs and poles, and for the carrying of supplies to the various camps.

"You're late, Tom," Jasper remarked as the boat's bow touched the sh.o.r.e where he was standing. "I expected you an hour ago."

"It was the wind, sir," was the reply. "A number of logs broke loose from the raft and I had a hard time to collect them. There's a heavy sea runnin' below the Bar."

"It's bad out there, too," and Jasper pointed off toward the island.

"Sure thing," the man replied, turning partly around. "There's a boat leavin' the island now. Surely it's not goin' to try to run over."

"Where is it?" Jasper demanded.
