Some half a dozen Indians were hurrying to the spot, coming almost directly from the rear, so that, if he remained where he was, he was quite sure to be surrounded, and cut off entirely from reaching the house.

Such a thing would have been madness upon the part of Sebastian, who instantly turned, and ran at the top of his speed toward the house, both parties of Indians converging in swift pursuit.

Katrina was on the look-out for him, and the instant he reached the door, it was drawn open to admit him, and then closed as quickly. She was prepared for such a crisis as this, and swift as came the Comanches, by the time they threw themselves against the door, the massive fastenings were in their place, and it presented as immovable a front to the assault, as the side of the cabin itself.

There was only one window upon the lower floor, and as soon as the Texan was certain of the door, he ran to this, reaching it scarcely a moment too soon; for the head and shoulders of a sinewy Indian were already through the opening.

The next minute, the body of the savage dropped back to the ground, as limp and lifeless as a log of wood.

The Bowie-knife had done its work!

This decided repulse of the Comanches had the result of making them more cautious. The whole party, numbering nearly a dozen, scattered like a covey of partridges across the clearing until they reached the wood, where they gathered together to consult how this fearful man was to be routed out and their fallen companion avenged.

Sebastian gazed after them and saw one of the men as he skurried away, bearing the body of the victim upon his shoulders.

Confident that they would speedily return to the assault, the Texan stationed himself in the lower room, rifle in hand, ready to pick off the first savage that exposed himself, while Katrina went to the upper story, which, having a window upon each side, gave a better outlook than from below.

As yet, the lovers had scarcely exchanged a word since entering the building, except that he gave a few hurried directions, during the first five minutes. The common danger was too great for wooing and winning at such a time.
