ed, who knows? My great concern,
though, is in connection with the work at the falls. I have the
feeling that in some way I am necessary to its welfare. I do not wish
it to stop, and I want you to promise me to-night that if anything
should happen to me that you will take my place, and be keenly
interested in it."

"I do not see how I can take your place, for that is not in my power.
But take a deep interest in all that goes on up there I certainly
shall, and be as deeply interested in its progress as you have been."

"Ah, you can never be interested in it as I am," and David's eyes
glowed with the intensity of his old-time devotion. "Can any one be as
much interested in the growth and progress of a child as its parents?
My child is up there," and he stretched out his arm toward the falls.
"For it I have longed and suffered. It is bone of my bone and flesh of

Jasper now felt certain that the old man's mind was really unbalanced.
He attributed it to the excitement of his narrow escape that afternoon.
A good sleep would refresh him, and he would be all right in the

without them."

Then he suddenly paused and caught Jasper fiercely by the arm.

"Do you hear them?" he asked. "Listen," and he held up his right hand.

In the old man's eyes had come a peculiar light, and his manner
reminded Jasper of the first night he had met him on the road when he
had rescued him from the speeding auto.

"Do you hear them?" David repeated. "My beautiful falls, my beautiful
falls. What sweeter music than the sound of your rushing water.
People have been deaf to your luring voice. I alone have listened and
understood. They called me a fool and said I was crazy, ha, ha! But
they know better now. They have seen what my beautiful falls can do.
Light and power! Light and power! The world transformed. Burdens
lifted from weary shoulders; homes transformed, and the hearts of all
made glad."

He was standing in th
