"Then let's put back."

"No, it would be too bad to disappoint Mr. Fenwick, now that we have made such a good start. He wants to make a long flight, and I can't blame him," spoke Tom, in a low voice.

"But if there's danger--"

"Oh, well, we can soon be at Cape May, and start back. The wind is freshening rather suddenly, though," and Tom looked at the anemometer, which showed a speed of twenty miles an hour. However, it was in their favor, aiding them to make faster time.

The speed of the Whizzer was now about forty miles an hour, not fast for an air craft, but sufficiently speedy in trying out a new machine. Tom looked at the barograph, and noted that they had attained an altitude of seven thousand five hundred feet.

"That's better than millionaire Daxtel's distance of seven thousand one hundred and five feet," remarked the lad, with a smile, "and it breaks Jackson's climb of seven thousand three hundred and three feet, which is pretty good for your machine, Mr. Fenwick."

"Do you really think so?" asked the pleased inventor.

"Yes. And we'll do better than that in time, but it's best to go slow at first, until we see how she is standing the strain. This is high and fast enough for the present."

They kept on, and as Tom saw that the machinery was working well, he let it out a little, The Whizzer at once leaped forward, and, a little later they came within sight of Cape May, the Jersey coast resort.

"Now to drop down and visit my friend," said Mr. Fenwick, with a smile. "Won't he be surprised!"
