eturning to the Chief Guardian to report that they
had found no trace of the missing girls.

"Keep moving. They may drift in," commanded Mrs. Livingston.

The search was again taken up, pairs of girls going over the ground
thoroughly, investigating every shadow, every sticky mass of sea weed
that caught their anxious glances, but not a sign of either of the two
girls did they find.

An hour had passed; then Mrs. Livingston called them in. She directed
certain groups to return to camp and begin getting the tents laid out,
and to put up such as were in condition to be raised. The Chief
Guardian herself remained on the beach with Miss Elting and the
Meadow-Brook Girls. There was little conversation. The women walked
slowly back and forth, scanning the sea, of which they could see but
little, for the night was still very dark. At first they tried calling
out at intervals, ceasing only when their voices had grown hoarse. To
none of their calls was there any reply. Harriet and Tommy were too
far out, and the noise about them was too great to permit of their
hearing a human voice, even had it been closer at hand.

Meantime the two girls were now swimming quite steadily. Harriet knew
that, were they to remain quiet too long, they would grow stiff and
gradually get chilled through. That would mark the end, as she well
understood. Then again it was necessary to give Tommy enough to do to
keep her mind from her troubles, which were many that night.

All the time Harriet was straining eyes and ears to locate the land.
She had not the remotest idea in which direction it lay, and dared not
swim straight ahead in any direction for fear of going farther away.
The wind died out and rose again. Had it continued to freshen from the
start, she would have permitted herself to drift with it, but Harriet
feared that the wind had veered, and that it was now blowing out to
sea, what little there was of it, so she tried to swim about in a
circle in so far as was possible. Tommy, of course, knew nothing of
what was in the mind of her companion, nor did Harriet think best to
confide in her.

"I'm getting tired. I can't keep up much longer," wailed Grace.

"Rest a moment on your back. I will keep a hand under your shoulders
so you won't sink. If only one knew it, it isn't really possible to
sink, provided the lungs are kept well filled with air and no water
swallowed."

"I could think like a thtone if I let mythelf go."

"Don't let yours
