The fact that they had been able to resist the first assault did not give him encouragement for the future. The Indians had advanced foolishly, understanding that the white people knew full well what they were about, and after this first repulse it was reasonable to suppose the murderous scoundrels would bring all their cunning into play when the next attack was made. There were six muskets in the stockade, and ammunition sufficient to last during an ordinary siege, provided none was wasted, yet but three persons--Susan, Luke, and himself--could be depended upon to man the walls. The others would have served faithfully, of that there was no question; but none of them were so expert with a musket as to be counted on for any great execution. Although the lad would not have admitted as much to either of his companions, the fear in his heart that the enemy might succeed in accomplishing his purpose was very great. "We can count on it that at the next attack they will succeed in getting inside the palisade," he said, unconsciously giving words to his thoughts, and he started almost in alarm as a familiar voice behind him asked, reproachfully: "If you lose heart, how can the rest of us be expected to show courage?" "What are you doing out here, Sue?" he asked, in turn, not minded to answer her question, if it could be avoided. "I've come to take Luke's place. He is sleeping so soundly that it is a pity to awaken him, and the pain in my arm keeps my eyes open very wide." "But I haven't been here two hours yet." "Nearly half that time has passed since you came on duty, and there is no reason why you should remain awake when it's impossible for me to sleep. I can keep a sharp watch." "So you can, Sue; but it is my place to take the biggest end, and I don't fancy the idea of letting a woman do my work." "If I could go to sleep it would be different; but since I can't, I shall stay here, therefore you might as well take advantage of the opportunity." Mark made no move toward leaving the platform, from which he could have a full view of the harbor, and, seeing that he was not disposed to act upon her suggestion, Susan clambered up beside him. "Now tell me what you meant by saying that the next time they come the Indians will get inside the fence?" "There's no sense in talking about that. I didn't count on speaking aloud." "You did, however, and now it will be treating me no more than fairly if you tell me exactly what is in your mind." Mark had no desire to discuss the situation just then, when it looked very dark to him, and, in order to avoid answering the question, he proposed to take advantage of Susan's proposition. "Since you are determined to stay here, I may as well get what sleep I can. Call Luke when you are tired," He said, and before she could detain him he had slipped down from the improvised platform, walking rapidly toward the dwelling.
