"I'll go up to the pipes," volunteered John. "And I can see from there."
Now, the pipes were great water conduits, the immense black iron kind that are used for carrying water into cities from reservoirs. They were situated quite a way from the dam, but as it was daylight John could see the gates as he stood on the pipes that crossed above the pond.
Usually boys could walk across these pipes in safety, as they were far above the water, but the flood had raised the stream so that the water just reached the pipes, and John had to be careful.
"What's that?" he said, as he looked down the raging stream.
"Something lies across the dam!" he shouted to the anxious listeners.
This was enough. In another minute every man was on the pond bank.
"The big elm!" they shouted. "It has saved the dam!"
What a wonderful thing had happened! The giant elm tree that for so many, many years had stood on the edge of the stream, was in this great flood washed away, and as it crossed the dam it broke the force of the torrent, really making another waterfall.
"It is safe now!" exclaimed Uncle Daniel in surprise. "It was the tree we heard crash against the bank. The storm is broken at last, and that tree will hold where it is stuck until the force goes down. Then we can open the gates."
To think that the houses were safe again! That poor Mrs. Burns could come back to the old mill home once more!
