"They all know you, Mr. David," Betty remarked. "Did you notice how the men lifted their hats!"

"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.
