The next day was like the day before, very hot and still, the air thick with a smoke-like mist even in that seashore place. It hung over the sea like a heavy fog, and the foghorn could be heard in the distance moaning like a distracted animal calling for its young.

Barbara had refreshed herself by an early morning dip in the ocean, but she felt the oppressive atmosphere in spite of the tingling the cool salt water had given to her skin.

They were seated around the little breakfast table, always so daintily set, for Mrs. Thurston had never lost that quality which had characterized her in her youth and which still clung to her in the days of her hardships and troubles.

“And now, girlies,” she said, “you must promise me one thing. Don’t lose your heads at the wrong time. Not that you ever have before, and I am sure I have no premonitions, now; but remember, my daughters, if anything exciting should happen, to make a little prayer to yourselves; then think hard and the answer is apt to come before you know it.”

“Do you remember how Gladys Le Baron shrieked the time the curtains in her room caught fire?” asked Mollie. “She didn’t do anything but just wring her hands and scream, and it was really Barbara who put the fire out. Bab pulled down the curtains and threw a blanket over them. And then Gladys had hysterics. But Barbara always keeps her head,” added Mollie, proudly.

“Your head is all right, too, Molliekins,” exclaimed Barbara. “The night the man tried to break in the house, don’t you remember, mummie, how brave she was? She followed us up with a poker as bold as a lion.”

“So you did, my pet, and I’m not the least afraid that either one of you ever will be lacking in courage. But, when I was very small, my mother once taught me a little prayer which she made me promise to say to myself whenever I felt the temptation to give way to fear or anger. And many and many a time it has helped me. It was only a few words: ‘Heaven, make me calm in the face of danger,’ but I have never known it to fail.”

“Dearest little mother,” cried Barbara, kissing her mother’s soft cheek, “you’re the best and sweetest little mummie in the world and I’m sure I can’t remember ever having seen you angry or hysterical or any of those terrible things. But if ever I do get in a tight place I hope I shall not forget the little prayer.”

“‘Heaven, make me calm in the face of danger,’” repeated Mollie, softly.

“But, dear me, how gruesome we are!” exclaimed Mrs. Thurston. “It is time you were packing your bags, at any rate, children. Be sure and put in your sweaters. You may need them in spite of this hot wave. And, Mollie, don’t forget the cold cream for your little sunburned nose.”
