know who had spoken, but the horrible tension
did not slacken yet, though Lawrence began to move forward. Walters
came close behind, rather guiding than supporting him, and in a few
moments they stepped down on the other side. Then Lucy gasped and logs
and pines got blurred and indistinct. She conquered the faintness and
went resolutely towards the log.

"Wait and let me help you," somebody said.

"No," she answered in a strained voice; "I'm quite steady."

She crossed the log without a tremor and running to where Lawrence sat
put her arm round him. Lawrence said nothing, but took and held her
hand.

FOSTER ARRIVES

When Lucy looked up, the others had gathered round and Walters smiled
sympathetically.

"Are you better?" he asked Lawrence.

"Yes; we'll go on in a minute. I don't know what was the matter; felt
dizzy and couldn't keep my balance. Think I needed a rest."

"The thing's obvious," Walters agreed. "After seeing you on the
glaciers, I reckon your nerve's all right, but you're not well yet and
we brought you up the last hill too fast. The exertion disturbed the
beating of your heart and a few drops too much blood sent to the brain
makes a big difference. That's what happened; it's our fault."

Lucy was grateful for the explanation, and thought it correct, but she

the meantime, Walters gave her a look of ironical amusement. She could
not resent this and it seemed ridiculous to doubt him, but she did.

"Thank you; you were very quick and cool," she said with an effort.

Walters tactfully bowed his acknowledgment, as if he did not want to
press his claim on her gratitude, and Lucy turned to one of the others.

"Was it you who held me back?" she asked, and when the man nodded,
resumed: "Of course, you were right. I might have startled him and we
would both have fallen."

"That's what I was afraid of. Anyhow, Mr. Walters deserves your thanks
most. He saw what was needed and did it smartly."

Then Lawrence got up, with some color in his face, and gave Walters his
hand. "I expect I would have fallen if you hadn't come along," he said
and turned to the rest. "I feel I must apologize for frightening you.
My best excuse is that I wasn't as fit as I thought."

They urged him to rest and one offered to run to the hotel for brandy,
but he decla
