When the Indian saw the head of the string groping its way through the little hole in the door like a tiny serpent, he grasped the end, and gave it such a smart jerk that the latch flew up. But, fortunately, it was necessary to do more than draw the latch to open the door. The massive bar was in place, and the Sioux, most likely with a suspicion of the truth, made no effort to force the structure. But while he was thus employed Red Feather had slipped from the back of his pony and approached the house. He took the side opposite to that from which Melville was looking forth, so that the youth did not notice his action. He saw the idleness of trying to make his way through the door, and formed another plan. With little effort he raised the sash in the narrow window on the right. About half-way to the top was a wooden button to hold the lower sash in place when raised. The occupants of the house used no care in securing the windows, since, as I have explained, they were too narrow to allow any person, unless very thin of figure, to force his way through them. Red Feather seemed to forget that he had tried to take the life of one of the white persons only a few minutes before; but, since no return shot had come from within the building, he must have concluded the defenders were panic-stricken, or else he showed a daring that amounted to recklessness; for, after raising the sash, he pushed the curtain aside, and began carefully shoving his head through the opening. Now, the house being of logs, it was necessary for the chieftain to force his shoulders a slight distance to allow his head fairly to enter the room. This required great care and labor, and more risk on the part of the Sioux than he suspected--since he should have known that it is easier to advance under such circumstances than to retreat, and, inasmuch as it was so hard to push on, it was likely to be still harder to retreat. Dot Clarendon, like her brother, was so interested in another direction that she failed for the time to note that which was of far more importance. But the feeling that she and her brother were in a situation of great danger became so strong that she felt there was only One who could save them, and, just as she had been taught from earliest infancy, she now asked that One to take care of them. Sinking on her chubby knees, she folded her hands, shut her eyes and poured out the simple prayer of faith and love to Him whose ear is never closed to the appeal of the most helpless. Her eyes were still closed, and her lips moving, when the noise made by Red Feather in forcing himself through the narrow opening caused her to stop suddenly and look around. The sight which met her gaze was enough to startle the bravest man. The head and shoulders of a hideous Sioux warrior were within six feet of where she was kneeling. The Indian was still struggling but he could get no farther, and, as it was, he was wedged very closely.
