She indicated the direction that the sledge had taken, and the dog ran out on the ice.

Zita looked after him. Would he be able to track them on the frozen sheet? Would the scent lie on the congealed water?

If Wolf did come up with his mistress and Mark, would he be able to arrest their course? Did he understand the message, the order given him? Would he, bounding forward in advance of the sledge, discover for himself the danger that lay ahead, and come back and warn them?

Should this attempt to stay the sleigh fail, were there no other means available?

Then an idea flashed through the brain of Zita. There remained one chance of staying their career.

Instantly Zita ran to the hut, burst open the door, and, seizing the mattress of Kainie's bed, dragged it forth across the platform, and threw it under the stationary sails of the mill.

Then she went back to the cottage, and, gathering up the red embers of the fire in a shovel, ran with them forth again, and threw them upon the straw mattress.

Next she stood, shovel in hand, waiting the result, watching as the fire burnt its way through the ticking and buried itself in the straw.

For a moment there ensued a red glare—an eating outward of the ticking by fiery teeth—then a ghost-like flame leaped up, and wavered above the incandescent mass. It threw itself high into the air, as though it were independent of the fire below, then returned and dipped its feet in the red ashes. With the shovel Zita stirred the ignited mass. Then the mattress broke into flame, and the flame reared itself in many tongues, swayed with the wind, curled over, broke into a multitude of orange fire-flashes that capered and pirouetted about the glowing heart of fire, as though the fabled Salamanders had manifested themselves, and rejoiced in being able to dance in their proper element. In another moment the flames had ignited the sail that hung above them, and were racing each other up the canvas.

Zita sped to the clog. She had learned from Kainie how a windmill was to be set in motion, and how the revolution of the sails was to be arrested, on the first visit she had paid to Red Wings. She now raised the clog, and with a sigh and creak the arms began to turn. As they did so, the sail which was on fire swept from the bed of flames that had kindled it, and was replaced by another. Instantly Zita stopped the revolution, to allow it also to be kindled. In like manner she treated the remaining sails, and when all blazed, she allowed them to spin unhampered in the breeze.
