At this moment the man, with his back toward her, struck a match. Mollie beheld the crouching figure. She could not tell who the man was. Was it Bill or her father come to steal her away? The old, dreadful fear swept over her, with enough of memory to make her realize what her capture would mean. The girl's first instinct was to hide. She did not realize how poor a refuge the houseboat offered her. It seemed to her that, if she could only get into one of the cabin bedrooms and conceal herself in her berth, she might escape. Poor Mollie had no better idea to aid her. She came running down the outside steps and ran toward the cabin door.

The man rose quickly. He did not move toward Mollie. Outside the cabin kitchen was a big box filled with chips and bits of kindling, used to light the kitchen stove. The man gathered up a handful of these pieces of wood and ran back to his old position. He glanced at Mollie. But it was easy to see that she was trying to get away, not to hinder him in what he was doing. He picked up the oil can again. This time he poured the few remaining drops on a little pile of chips and lit another match. The tinder blazed up. The man fanned the tiny flames with the brim of a torn hat. The flare of light grew brighter; a great flame leapt up and then a snake-like curve of fire followed the oil-soaked wood.

When the man did not move toward Mollie she stopped in the cabin door. She was afraid of him. She was not like other girls. Ever since she had been able to know anything she had felt a curious, confused feeling in her head. She did not know who the man was on the deck of the boat. But she did know that he was trying to set their houseboat afire.

Mollie paid no further attention to the man. She did not scream at him, nor try to stop what he was doing. She rushed forward and began stamping on the pile of blazing sticks.

The man did not attempt to prevent her. He was watching the increasing length of flame spread over the deck. A second later he sprang up, ran across the deck, slipped over the side of "The Merry Maid," dropped into his rowboat, and rowed swiftly out of sight.

Mollie flew for the big bucket of water, which they always kept in a certain spot. She flung the water on the flames, but water will not quench the flames made from oil. The rail began to crackle, the sparks to fly. The "Merry Maid" was afire, with only one, feeble girl to save it!

Mollie knew that there were steamer blankets in the bedrooms of the cabin. She often had one to cover her when she took her afternoon rest. Remember, Mollie had had little education, but she had been brought up to work and to do practical tasks. It was but the work of a moment to drag out two blankets and spread them over the flames. The fire died down for a moment; then it crept through the fringe of the rugs, and a choking smell of burning wool showed that the blankets also were beginning to burn. But the brave girl had no intention of giving up the fight.

There were two other blankets left. Mollie started back to the cabin for these, when to her terror she discovered that the skirt of her cotton dress was in names. She tried to beat it out with her hands, but it crept steadily up toward her head. She cried aloud, but she could see no one coming to save her. The pain was more intense every moment. She could not keep still. She ran toward the edge of the deck. Before her the placid water lay cool and sweet. With a cry of pain, Mollie threw herself over the side of the houseboat. She did not realize how shallow the water was. She flung herself with all her force. Her head struck against the bottom with a heavy thud. At least the water was cool; the fire no longer burned her.

Miss Jones and Mr. Brown, who had joined Miss Jenny Ann on her way back from the farmhouse, heard Mollie's first cry of alarm. The artist had been coming down to the houseboat to make an evening call. Two strangers, a man and his wife, were strolling along the top of the small embankment. They also heard the call. The four of them started down the hill almost at the same time. Before they reached the houseboat, the odor of burning wood was borne to their nostrils. Miss Jenny Ann cried out for Mollie, but Mollie did not answer. Mr. Brown and the two strangers began beating out the fire on the boat. It had not spread far; the blankets had covered the flames and kept them from increasing. The overturned oil can gave the clue to the mystery. Mr. Brown dashed into the kitchen for a bag of salt, because salt more quickly puts out the flames from burning oil.

Miss Jenny Ann had, so far, been unable to find Mollie. Now she looked over the side of the boat, and Mollie's body could be plainly seen lying in the shallow water. Mr. Brown and the stranger together brought the girl back to the houseboat. She was insensible. In her plunge into the water she had struck her head with great force against the bottom of the bay. She was stunned by the shock, and when she returned to consciousness the pain from the burn and the blow made her delirious. As she alone could tell what had transpired in that brief hour, the cause of the fire remained a mystery.
