"It's a big machine all right," murmured Innis.

"And there are three aviators in her," added Paul.

"Can you make out who they are, Dick?" asked Larry Dexter.

"No, they have on protecting helmets and goggles," replied the young millionaire, as he adjusted the binoculars to his vision. "But I'm sure I know that machine!"

"Whose is it?" Innis wanted to know.

"Well, I don't want to be too positive, but I'm pretty certain that's my Uncle Ezra's craft," replied Dick, slowly.

"Great Scott!" cried Paul. "Is it possible? Oh, it's possible all right," Dick made answer, "but I did not think he would really take part in this race. However, he seems to have done so. I can't make him out, but that's just the shape of his airship, I can tell by the mercury stabilizer Larson has put on."

"Well, it looks as if we'd have a race," observed Mr. Vardon.

"He sure is speeding on," mused Dick.

"But he may be away behind his schedule," put in Larry.
