ddings can't handle
the natives. You do that for me."

"It is too late," said Ambrose grimly. "He is gone with it."

"Gone?" she exclaimed, with raised eyebrows. "How do you know?"

"He came to my camp at dawn," said Ambrose. Honesty compelling him, he
added with a touch of defiance; "I gave him my dugout."

Colina shrank from him.

"You helped him get away!" she cried.

"I didn't know what had happened," he said indignantly.

"Of course not!" said Colina, with quick penitence.

But she did not return to him. Presently the frown came back; she
began to breathe quickly. "You saw the skin; you must have talked with
him. You took his part against father!"

Ambrose had nothing to say. He could have groaned aloud in his
helplessness to avert the catastrophe that he saw coming.

It was as if a horrible, black-shrouded shape had stepped between him
and Colina.

She, too, was aware of it. For an age-long moment they stared at each
other with a kind of chilled terror.

Neither dared speak of what both were thinking.

skin to us? I pledge myself to transmit whatever price it brings to
your father. Won't that do?"

"Don't say anything more about it," said Colina painfully. "You're
right; we mustn't quarrel about a thing like that."

A wretched constraint fell upon them. For the moment the catastrophe
had been averted, but both felt it was only for the moment.

They had nothing to say to each other.

Finally Colina moved toward the door.

"I must see if anything is wanted up-stairs," she murmured. "Wait here
for me."

CHAPTER XIII.

THE QUARREL.

When Colina returned she said immediately: "Ambrose, can you stay at
Fort Enterprise a little while longer?"

His heart leaped up. "As long as I can help you!" he cried.

They looked at each other wistfully. They wanted so
