"They mean to overpower us if they can," cried Dan. "We must load up as fast as we can!" The Indians, or at least the three that were not wounded, had now gained the door, and were trying to force it open. But their hatchets and the axe they had brought along failed to make much of an impression on it, and all they could do was to shout in their rage and demand that the boys open the door at once. "Open! Open!" came in Wolf Ear's voice. "Open, or we will scalp you!" "Go away, or we'll shoot you all down!" answered Dan, who had now reloaded his gun. "We will not go away. What is in the house belongs to the red man, and he must have it." "It belongs to our father, and you shall not have one thing," retorted Dan. He had unbarred the shutter of one of the upper windows, and now, leaning out swiftly, he took aim at the forms grouped below, and fired. A howl went up, for the bullet had nipped one red man in the ear and glanced along the shoulder of a second. Then came a quick fire in return, and Dan gave a scream that caused Ralph's heart to almost stop beating. "You are struck?" queried the younger brother. "It's not much," came from Dan, and, breathing heavily, he flung to the window-shutter and bolted it again. Then he came down the ladder, the blood flowing from a wound in his neck. Had the bullet come two inches closer, Dan would have been killed on the spot. The Indians were now trying to batter the door down with a log of wood picked up close at hand. The cow bothered them in their efforts, and one of the red men had to take time to cut her loose, at which the cow ran off to the cattle shed once more. Thus far three of the attackers had been wounded, one quite seriously. The other two continued to hammer away at the door, which presently showed signs of giving way. "Let us try to fire through the door," whispered Ralph, when he saw that his brother was still able to continue the struggle. "We may hit them, and, anyway, we'll give them a scare." Dan nodded, and both drew closer to the barrier with their guns. But before they could level their firearms, there came a report from the edge of the timber next to the burn, and one of the Indians was heard to yell in mortal agony and fall on the doorstep. "Somebody is coming!" cried Dan, joyfully. "It must be father!" Then a second report rang out, and another red man was struck, in the arm. This was the savage who had previously been nipped in the ear, and, without waiting for another shot, he sped away in the darkness, and his two companions after him, leaving the dead Indian where he had fallen. There was now no use of trying to fire through the door, and Dan motioned Ralph to run up to the loft. "See if you can make out who it was that fired," he said, "and if it is father, and he wants to come in, call for me to open the door."
