At any mention of the names Ambrose Doane or Nesis a subtle, walled look crept into their eyes, and they became unaccountably stupid.

She was about to give up this line of inquiry when, at a little distance from the nearest teepee, she came upon a girl engaged in dressing a moose-hide stretched upon a great frame. There were no other Indians near. Colina resolved upon a last attempt.

CHAPTER x.x.xVII.

MARYA.

Colina drew near the girl, pausing as if casually interested in her work. She was a fat girl, with a peculiarly good-humored expression, and evinced no awe at Colina's approach, but unaffected delight.

Colina obeyed an inward suggestion, sent Cora back to the Grampierres, and sat down beside Marya, determined to take plenty of time to establish friendly relations.

This was not difficult. The plump, copper-skinned maiden was overjoyed by the opportunity to examine anything so wonderful as a white girl at close range.

No part of Colina's person or attire escaped her scrutiny. Marya stroked her with a soft crooning. The fastidious Colina bore it, smiling. At the throat of her waist Colina was wearing a topaz-pin, to which the Indian girl's eyes ever returned, dazzled.

Colina finally took it off, and pinned it in Marya's cotton dress.

Marya gave way to an extravagant pantomime of joy. Bowing her head, she seized Colina's hand, and pressed it to her forehead.

Meanwhile they exchanged such simple remarks as lent themselves to the medium of signs. Colina finally ventured to p.r.o.nounce the name "Nesis"

at the same time asking by a sign which included the teepees if she was there.

Marya looked startled. She hesitated, but Colina's hold was now strong upon her. She shook her head. First glancing cautiously around to make sure they were not observed, she nodded in the direction of up river.

By simple signs she told Colina that Nesis was in a village (crossed fingers for teepees) beside a lake (a wide sweep, and an agitated, flattened hand for shimmering water), and that it could be reached by a journey with one sleep upon the way. (Here she paddled an imaginary canoe, stopped, closed her eyes, inclined her head on her shoulder and held up one finger.)

Colina, overjoyed, proceeded to further question. In the same graphic, simple way she learned the story of Ambrose's imprisonment and how Nesis got him out.

"Come!" she cried, extending her hand. "We'll see what Sergeant Plaskett has to say to this!"

But when Marya understood that she was expected to repeat her story to the policeman, a frantic, stubborn terror took possession of her. She gave Colina to understand in no uncertain signs that the Indians would kill her if she told the secret.

Colina, taking into account the pains they had gone to to keep it, could not deny the danger. She finally asked Marya if she would take her, Colina, to the place where Nesis was.

Marya, terrified, positively refused.

Pulling off her gauntlet, Colina displayed to Marya a ring set with a gleaming opal. It was Marya's she let her understand, if she would serve her.

Marya's eyes sickened with desire. She wavered--but finally refused with a little moan. Terror was stronger than cupidity.

Colina debated with herself. She asked Marya if the way to go was by paddling.

Marya shook her head. She gave Colina to understand that the canoes were all tied up together and watched by the police. She signed that the Kakisas had a few horses up the river a little way that the police did not know about.

They stole out of camp at dawn, caught a horse and rode up the river.

Evidently there was regular travel between the two villages. Colina, thinking of the policeman's confident belief that he had intercepted all communications, smiled.

Colina finally asked if Marya would put her on the trail to the other village--in exchange for the ring. Marya, after a struggle with her fears, consented, stipulating that they must start before dark.

Colina understood from her signs that the biggest opal ever mined would not tempt Marya to wander in the bush after dark.

Colina did some rapid thinking. She doubted whether Germain Grampierre after having been warned by the police would go with her to the other village.

She quickly decided that she didn't want him with her anyway, worthy, stupid fellow that he was. Yet he had const.i.tuted himself her protector, and he would hardly let her go without him. It did not promise to be easy to hoodwink both Plaskett and Grampierre.

What she was going to do when she found Nesis, Colina did not stop to consider. The thing to do was to find the girl, and trust to pluck and mother wit for the rest.

Colina finally thought she saw her way clear. She asked Marya if she would meet her in an hour on the Enterprise trail outside of camp. It was now three o'clock.

Marya, with her eyes upon the opal, nodded. She gave Colina to understand that she would be waiting at a place where the trail crossed a stream, and climbed to a little prairie with thick bushes around it.

Leaving Marya, Colina returned to the police tents. Climbing the hill, she had the satisfaction upon looking back to see that the Indian girl had foresaken her moose-hide.

The edge of the bush was near her: it would not be hard for her to lose herself. Simulating an air of discouragement, Colina told Sergeant Plaskett she had learned nothing and signified her willingness to return to Enterprise.

"I'd start at once," she said suggestively, "but my horses are tired."

Plaskett was greatly relieved. "I'll furnish you with fresh horses,"

he said instantly. "Let your horses stay here and rest up. I'll send them in with the first patrol, and you can then return mine."

This was what Colina desired. She smiled on the policeman dazzlingly.

Plaskett sent a trooper for the horses, and himself escorted Colina back to the spot at the foot of the hill where she had ordered the Grampierres and Cora to wait for her.

She told Germain the same story. The half-breed who had been interviewed by Plaskett in the meantime, was delighted by her resolve to return. He instantly set to work to pack up.

In less than half an hour they started for home. As they mounted the hill, Plaskett gallantly waved his cap from below. The bush swallowed them. Colina was thinking: "What shall I do if she is afraid, and doesn't come?"

However, less than a mile from the river, they forded a little brook, climbed a shallow hill, and there, true to her agreement, waited Marya, standing like a statue beside the trail.

Colina, making believe to be greatly astonished, dismounted, and drew her apart. Marya, understanding from her glance of intelligence that the others were not in the secret, gesticulated vividly for their benefit.

"She tells me she knows where Nesis is hidden," Colina said to Germain.

"She says she will take me there."

"We will go back," said Germain.

Colina shook her head. "No need for you to come back," she said. "It will only anger the policeman. You and Georges go on home. I will get a policeman to go with me."

Germain protested, but his secret desire was to obey the sergeant's orders, and Colina had no difficulty in persuading him.

A division of the baggage was made on the spot, and they parted. The Grampierres continued toward Enterprise, and the three girls turned back.

Colina breathed more freely. Plaskett now believed that she had gone home with Germain, and Germain believed she had gone back to Plaskett.

Marya had mounted on their pack-horse. They had not gone far in the trail, when she signified that they were to strike off to the left.
