Granny was laughing so that she could scarcely tell them what it was. So was old Peter Simmons.

"You see, dears," began Granny, breaking a laugh in two and wiping the tears from her eyes, "we felt older twenty-five years ago than we do now, didn't we, Peter? And we wanted to do something for the world that had been so good to us. We had had twenty-five as perfect years as a man and woman could have together, and we wanted to show that we appreciated them. Peter thought of a trade school, and I thought of a children's home because women naturally think of children, you know, and then we had an inspiration. I don't remember which thought of it first, do you, Peter?"

"I expect you did," old Peter suggested handsomely.

"Well, perhaps I did, but it doesn't matter, for when two people live together for twenty-five years they grow to think the same things. Yes, they do, Rebecca Mary, as you'll see some day. I often catch myself thinking of contracts. But this time we thought of a home for old couples. We were so sorry for the old couples who couldn't grow older together that we decided that we'd give them a home when we had been married fifty years and were an old couple ourselves. A home for friendless old couples. We shouldn't wait until we were dead and some one would look after it for us. We'd do it ourselves and get to know some of the old couples. That was why we bought Seven Pines, wasn't it, Peter? And that was why I wanted to take you to Seven Pines, Rebecca Mary. I wanted to go there to stay for a few days before my golden wedding. We've talked and planned a lot about it, and I was a silly old fool to let Peter tease me with his question. I should have known you, Peter, but perhaps it was because it meant so much to me that I was frightened to death for fear you had forgotten or changed your mind. But you hadn't for—— See!" She held up the envelop old Peter had given her, and her face was radiant as she told them what was in it. "Here is the deed all ready for me to sign for the Katherine Simmons Home for Old Couples."

"And here," old Peter Simmons held up the envelop which had been given to him, "here is the deed for the Peter Simmons Home for Old Couples all ready for me to sign. We'll have to compromise on the name, Kitty, and merge it into the Simmons Home."

"Is that all the present is?" Joan had never been more disappointed in her life. She could not join in the chorus of admiring approval. But she could understand why Granny cried. She would want to cry if old Peter Simmons gave her an old home for old people. There was only one thing which would make it right to Joan, and she pulled Granny's sleeve. "Will you give the old couples young hearts, Granny?" she whispered eagerly.

"We'll try," Granny whispered back. "That's exactly what we are going to try to do, Joan, to make tired old hearts younger. The world would be so much happier if there were not so many old hearts in it. You keep yours young, Joan, as long as you live," she advised quite confidentially. "Bless my soul!" she exclaimed as she heard a machine puff up the driveway. "Is that young Peter with our jailor? I've been so taken up with our golden wedding presents, Peter, dear, that I never asked how your experiment worked. Was it a success?"

"It was a big success." Old Peter Simmons looked as if he was more than satisfied with the way the great experiment had worked. "We've given it every sort of try out and it can't go wrong. If we hadn't made sure of that I couldn't have come to your golden wedding, Kitty. I should have had to send my regrets." He winked at Rebecca Mary and tickled Joan under her chin. "Some day, Miss Wyman," he told her more soberly, "you will be proud to remember that you were a prisoner at Riverside when Befort's big idea was worked out."

"What will it do?" Joan wanted to know at once. "What can you do with my father's idea, Mr. Simmons?"

Mr. Simmons tickled her under her chin again. "That would be telling," he whispered with a great show of secrecy. "And then you wouldn't be curious any longer. There is only one way to keep people interested and that is to keep them guessing," he went on with a twinkle. "If you knew what to-morrow was going to bring you wouldn't care whether you had a to-morrow or not. You'd never want to go to bed to-night."
