“Everything’s all right,” he called to her.  “Don’t get scared.  Will you help me put these flaps down?”

Carol leaped from her bed at that, and ran to lower the windows.  Then she sat by David’s side while the storm raged outside, roaring and piling sand against the little tent.

After that, to bed once more, still determinedly in love with the land of health, and praying fervently for morning.

Soon David’s heavy breathing proclaimed him sound asleep.  But sleep would not come to Carol.  She gazed as one hypnotized into the starry brightness of the black sky as she could see it through the window beside her.  How ominously dark it was.  Softly she slipped out of bed and lowered the flaps of the window.  She did not like that darkness.  After the storm, David had insisted the windows must be opened again,—­that was the first law of lungers and chasers.

She was cold when she got back into bed, for the chill of the mountain nights was new to her.  And an hour later, when she was almost dozing, footsteps prowled about the tent, loitering in the leaves outside her western window.  David was sleeping, she must not interfere with a moment of his restoring rest.  She clasped her hands beneath the covers, and moistened her feverish lips.  If it were an Indian lurking there, his deadly tomahawk upraised, she prayed he might strike the fatal blow at once.  But the steps passed, and she climbed on her knees and lowered the flaps on the side where the steps sounded.

Later, the sudden tinkle of a bell across the grounds startled her into sitting posture.  No, it wasn’t David, after all,—­somebody else,—­some other woman’s David, likely, ringing for the nurse.  Carol sighed.  How could David get well and strong out here, with all these other sick ones to wring his heart with pity?  Were the doctors surely right,—­was this the land of health?

Again footsteps approached the tent, stirring up the dry sand, and again Carol held her breath until they had passed.  Then she grimly closed the windows on the third side of her room, and smiled to herself as she thought, “I’ll get them up again before David is awake.”

But she crept into bed and slept at last.

Early, very early, she was awakened by the sunlight pouring upon the flaps at the windows.  It was five o’clock, and very cold.  Carol wrapped a blanket about her and peeked in upon her husband.

“Good morning,” she greeted him brightly.  “Isn’t it lovely and bright?  How is my nice old boy?  Nearly well?”

“Just fine.  How did you sleep?”

“Like a top,” she declared.

“Were you afraid?”

“Um, not exactly,” she denied, glancing at him with sudden suspicion.

“Did the wind blow all your flaps down?”

“How did you know?”

“Oh, I was up long ago looking in on you.  We’ll get a room over in the Main Building to-day.  It costs more, but the accommodations are so much better.  We are directly on the path from the street, so we hear every passing footstep.”
