We had no idea. There were spaces in the outer log walls where the morticed filling had fallen away. But only blackness showed. In the adjoining room there was candlelight, and the drowsy voices of the Dutchmen. "Alan, what's that?" A thud had sounded; something striking the roof over our heads. Then another. Off in the woods there was a shout. A war-whoop! And other thuds. A rain of arrows falling upon the roof and the side of the little fort. An Indian attack! The Dutchmen in the adjoining room made short work of getting out of this isolated building. They did not come in even to look at us. They decamped into the woods, running for the village stockade. We were left alone. Helpless! The rain of arrows kept on. We could hear the Indians shouting, but they did not advance. The dawn was coming. Or was it the dawn? A red glow showing through the log walls. Red and yellow. I smelled smoke! Alan coughed with a sudden choking. The little log blockhouse was being bombarded with flaming arrows. It was on fire, filling up with smoke which already was choking us! CHAPTER XV THE RESCUE Lea and San--after Alan and Lentz left them--kept watch in the tower. They talked together in their own language. "How long do you think, brother, that they will be gone?" "Until dawn perhaps. We can only hope for the best. Alan is resourceful--he got you away from Turber, Lea." They could not guess what Alan and Lentz would do to rescue Nanette and me. They discussed Lentz. A fellow of their own Time-world. Their father had always put great trust in him. But Lentz had known Turber there. Was he a traitor now? A fellow in the pay of Turber? There had been several little things which Alan had brought to light--things to make them suspicious of Lentz. And they knew Alan did not trust him. The hours passed. The forest was a black wall of silence about the tower. Lea often stood in the doorway, staring out. Small, graceful figure in flowing blue robe and golden hair. We had seen her on the television like that--our first sight of her. San would not be still. As always when the tower was at rest in a strange Time-world, he constantly paced the room; peering alternately from each of its windows; always within a few feet of the tower controls so that at any hostile sign outside, in a second or two the tower would speed away. Time dragged by. Lea grew increasingly worried. Alan should be back by now. "If he would have taken me," she said. "You remember, San, when we were here once before? There was an old chief--Silver Water, you remember? I could have got him then to help me try for Turber in one of Turber's passings. But you would not let me." "You are over-bold, Lea." San shrugged. "I am helpless--always here with the tower." "I could, tonight, have enlisted a band of these Indians," she said. "They worshiped me for a goddess--the 'God of Magic,' old Silver Water called the tower."
