A second later the fire bell was loudly clanging and several of the crowd melted away to don their helmets and coats. In less time than the boys would have thought it possible a good-looking engine came rumbling out of the fire house half a block down the street. Behind it came a hook and ladder truck.

Fine horses were attached to each, and from the way they leaped off the boys saw that the "Chief" meant to make good his promise.

"Race you to ther fire!" shouted the latter functionary, as, in a storm of cheers, his apparatus swept out of sight down the elm-bordered street.

"You're on," laughed Roy, whisking aloft while the Topman's Cornerites were still wondering within themselves if they were waking or dreaming.

CHAPTER VI.

THE GIRL AVIATORS IN DEADLY PERIL.

The fire was out. A smoldering, blackened hillock was all that remained of the stack ignited by the lightning bolt; but the others and the main buildings of the farm had been saved.

Such work was a new task for aëroplanes—but there is no doubt that, had it not been for Peggy's suggestion, the Hutchings farm would have been burned to the ground. As it was, when the firemen, their horses in a lather, arrived at the scene, the farm hands, who had been fighting the flames, were almost exhausted.

Had they possessed the time, the young folks would have been glad to tell the curious firemen something about their aëroplanes. But it was well into the afternoon, and if they intended to keep up their itinerary it was necessary for them to be hurrying on. A short time after the blaze had been declared "out" the aëroplanes once more soared aloft, and the auto chugged off in the direction of Meadville.
