A small door gave entrance to the boiler-room, and into the lock of this Mrs. Austin fitted a key; the next moment she and Paloma were safely inside. They found themselves in utter darkness now, with a smooth brick floor beneath their feet and a strong odor of oil and burnt fuel in their nostrils.

Alaire was agreeably surprised in Paloma Jones, for, although the girl was wrought to a pitch of hysterical excitement, she had, nevertheless, retained her wits; nor had she faltered in the slightest. It was evident that the fighting blood of her father was aroused in her, for she said, calmly:

"When it gets light enough to shoot, I'm going to get Tad Lewis."

"Don't act too quickly," cautioned Alaire. "Perhaps your father and Dave have come and gone. Anyhow, we can warn them just as well by firing into the air."

In reply to this suggestion Paloma merely muttered something under her breath.

The brief night ride had given Alaire time in which to recover from her first apprehensions, and now she was surprised at her own coolness. Ed's behavior had shocked and horrified her; she was still half paralyzed at his treachery; nevertheless, her mind was clear, and she was determined to avert a tragedy if possible. She knew only too well what would happen when Blaze Jones and Dave Law encountered the Lewis gang; the presence of Longorio's soldiers merely made more certain the outcome of that meeting. The general was furious; it was plain that he would not tolerate this expedition, the avowed purpose of which was to prove him a liar. It would make but little difference, therefore, whether the quest for Ricardo Guzman's body had been successful or not: even the fact that this was American soil would not deter Longorio from violent action, for the Rio Grande was no real boundary, and this part of Texas was as truly Mexican as that other river-bank which lay two hundred yards distant.

A confusion of such thoughts were racing through Alaire's mind as she felt her way out of the boiler-room and into that part of the building where the pumping machinery stood. Dusty, cobwebbed windows let in a faint ghost-glow of moonlight, but prevented clear observation of anything outside; Alaire's fumbling fingers found the latch of the front door and began to lift it, when some one spoke, just outside the building.

"What did you discover?" inquired a voice which neither woman recognized. Paloma clutched blindly for her companion; the two eavesdroppers stood rooted in their tracks. The pounding of their hearts sounded loudly. Since the building was little more than a wooden shell, they could plainly hear the answer:

"The house is full of Greasers. I can't tell who they are."

A third man spoke, this time in Spanish. "That was Tad Lewis who just came, señor."
