Jack himself was almost blinded and deafened. He was strapped to his seat, so could give both hands to the work of manipulating the levers. He brought the Snowbird through the cloud and—with startling suddenness—they shot out of the mass of rolling moisture and into the sunlight of the dawn. But they were far off their course.

The change from the chaos of the storm-cloud to the almost perfect calm of the upper ether was so great that it was almost stunning. For a minute none of the five spoke a word.

Then it was Mark who shouted:

"There's that 'plane again, Jack I Look out for her!"

The enemy had missed them. She was some miles away, and although still on a level above, at the pace the Snowbird was now traveling it would take a fast flying machine indeed to overtake her.

The pursuit of the enemy (which they all believed to be the smuggler, manned by Bainbridge and his friends) was not kept up for long. By eight o'clock the Snowbird had dropped the other machine below the horizon, and the swift pace at which they had driven the Snowbird was rapidly bringing them once more toward Canada.

The storm had broken, but the clouds still hovered below them. They descended about noon, passing harmlessly through the vapor which had so long hidden the earth from them, and so came to within a thousand feet of the ground, where they swung along at fair speed for some hours.

They crossed the line, but did not descend until near St. Thomas. They went out of their way a good bit to land near this town on the shore of the St. Lawrence, for the flying machine had been so shaken in its struggle with the thunderstorm that some repairs were needed.

They descended in a field on the edge of the town, gave the farmer who owned the place a five-dollar bill to allow the machine to stand on his land, and then engaged him to drive Professor Henderson and the boys into town.

While the professor saw the authorities and obtained a legal document recommending the exploring party to the good offices of all British-Canadian officers whom they might meet, the boys went to a machine shop to have a rod repaired. The party took supper with the farmer, and an hour later the flying machine being pronounced by both Mark and Jack in perfect order, they got off amid the cheers of the onlookers, whose numbers were by that time swelled to almost five hundred persons.
