"Fire! fire!" screamed the two girls, assisted by all the females in the house. The planter, Levi, and the boys ran with all their might to the point from which the alarm came. Before they reached it a considerable cloud of smoke rose from the rear of the building, indicating the locality of the fire. "The house is on fire!" screamed Dorcas. Major Lyon ran into the house; but Levi, as soon as he saw the smoke, rushed around the mansion, followed by the two boys. In the rear of the building was an ell, to which a one-story structure had been added as a storeroom. The flames rose from this part of the house. Against it was heaped up a pile of dry wood and other combustibles, and it was instantly apparent to the overseer that the fire was the work of an incendiary. No time was to be lost, for the flames were rapidly gathering headway, and in a few minutes the whole mansion would be on fire. The hands began to appear on the spot, and Levi sent the first one to the stable for pitchforks; but he did not wait for them, and began to draw away the combustibles with such sticks as he could obtain. The boys followed his example, and the dry wood, blazing against the side of the storeroom, was soon removed from its dangerous proximity to the building. The work was effectively completed with the pitchforks as soon as they came. "There are three men running away towards the swamp!" shouted Deck. "I see them!" added Artie. "Put the fire out first, and we will attend to them afterwards!" said Levi. "Keep an eye on them while you work, and see where they go." The burning brands were removed from the house, but the flames were already communicated to the building. Mrs. Lyon had not gone out at the front door with the girls, but had rushed to the storeroom, where she was soon joined by her husband. All the buckets in the house were brought into use, including half a dozen leather ones that hung in the main hall, and all the women were carrying water to the exposed point. The fire had not yet come through the side of the building, and the buckets were passed out the window to the overseer. In a few moments the fire was thoroughly drowned out, and everybody breathed more freely. The lieutenant and the recruits had followed the others, and assisted in putting out the fire. Deck and Artie turned their attention to the three men they had seen, and had started in pursuit of them; but Levi called them back. Then he sent to the fort for several revolvers, not doubting that the men who were engaged in this desperate venture were armed.
