"They are running out!" cried Jack. "They are flying before her."

In the open space below, the Kachins were running swiftly from the entrance to the vault. Some looked over their shoulders, as if fearing pursuit.

"Very possibly," said his father. "They are running for the moment, but I fear they have done their work. See how joyous they look!"

This was quite true. The dark faces of the little mountaineers were bright with smiles, and their teeth flashed white as they grinned at each other, and shouted as if in triumph.

"Their muskets at close range are not to be despised," murmured Mr. Haydon uneasily. "They fling a heavy ball, and drive it with great smashing power. And again, the bullets may be poisoned. They often are."

The Kachins did not run far. They faced about, and three or four who were armed with spears threw their weapons forward, ready to receive the charge of the wounded creature. But no charge was made. Had the tigress been alone, she would have rushed out, but the presence of her cubs made a great difference. She stayed beside them, growling and roaring with rage and pain until the very building shook.

Half an hour passed, and the tigress was now making no more than a low moan. Little by little her growling had died away. The Haydons heard the sound diminish with uneasy hearts. They knew that the strength of the great fierce beast was going with it, and that very soon the Kachins would be at the foot of the stairs.

They talked the situation over, and looked at it from every point of view, but could see only one thing to do. That was to wait for the enemy on the narrow winding steps, where but one could pass at a time, and hold them at bay.

Jack looked round. "Where's the woman?" he said, "she has not come up."

"No more she hasn't," said his father. They had been so deeply engaged in watching every movement of their enemies that they had utterly forgotten their companion. When Jack rushed up from the secret chamber, he had thrust the flaring torch into her hand, in order that she might follow at her leisure, but there was no sign of her in the room behind them.
