"Yes, indeed," insisted Betty. "I thought I was climbing into a box and went in feet first without looking. Instead of hitting the floor, I slid gently on and on. I hadn't any breath to scream with I went so fast. Anyway, there wasn't time to scream. I just sat here for a time after I landed. And I was wondering where I was and how I could get out when you opened the door for me."

That ended the game for the day, and the rest of the afternoon the girls were content to spend quietly, Betty in writing a long letter to Mrs. Arnold, one of her mother's old friends who had moved to California, and the others with books and sewing.

The next morning was fair and sunny, and before breakfast Bobby had it planned that they should spend the day at Mount Vernon. Of course Betty and Libbie were very anxious to see the famous place, and the three sisters were glad to have the opportunity to take them for the first time.

"It's never the same again," explained Louise, obligingly tying Esther's hair-bow for her. "There's a wonderful thrill you get when you see the things that really were Washington's and were handled by him that never comes again. Though we love to go there and never tire of looking at the rooms."

"What a chatter-box you are, child!" expostulated her mother, who had come up to tell them breakfast was ready. Indeed the gong had sounded fully fifteen minutes before. "How nice you look, all of you! I'll be proud to take five girls to Mount Vernon. We're going to-day, aren't we?"

Dear Mrs. Littell! Betty already loved her dearly, as indeed did every member of the household. She was so unaffected, so affectionate and generous, and she allowed money to change her simple, happy nature not at all. The Littells had not always been wealthy, and the mistress of the beautiful mansion did not hesitate to tell of the days when she had done all of her own housework and taken care of two babies.

Soon after breakfast the party started, the plan to go by motor being abandoned in favor of the trip down the river. It was decided that Carter should come down later with the car and bring a basket luncheon, taking them home in the afternoon.

Mount Vernon is sixteen miles below Washington, and the sail down the Potomac was delightful in the cool of the morning, and Betty thought she had never seen anything more beautiful than the deep greens of the trees and grass on either bank. By common consent the boatload of chattering people became silent as they came in sight of Mount Vernon, and as the glimmer of the house showed white between the trees. Betty's heart contracted suddenly. Louise, who was watching her, squeezed her arm sympathetically.

"I know how you feel," she whispered. "Mother told me that the first time she went abroad and dad took her to see the Colosseum she cried. You're not crying, are you, Betty?"

Betty shook her head, but her eyelashes were suspiciously damp.
