"I wonder what's the matter?" spoke the young millionaire. "I never saw him act this way before. What is it, old boy?" he asked soothingly.

Grit whined uneasily.

"Sometimes animals have premonitions," said Mr. Vardon. "I remember once, in my early days of flying, I took a dog up with me.

"Everything seemed to be going along fine, but the dog showed signs of uneasiness, though it wasn't on account of the height, for he'd been up before. But it wasn't five minutes later before one of my propeller blades broke off, and I nearly turned turtle before I could make a landing."

"I hope nothing like that occurs now," said Larry. "It might make a good story, but it would be a mighty uncomfortable feeling."

"I don't anticipate anything," said the aviator. "We seem to be doing very well. But we are making scarcely any progress, and we are being blown considerably off our course."

"We'll make it up when the wind stops," Dick said. "I'm determined to win that prize!"

"This is a peculiar storm," Lieutenant McBride observed. "It seems to be nothing but wind. I'm inclined to think there had been an area of low pressure about this region, caused possibly by some other storm, and the air from another region is now rushing in, filling up the partial vacuum."

"In that case we might try to rise above it," suggested Mr. Vardon. "I've often done that. We could go up. It would not be advisable to go down any lower, as we don't want to run the risk of colliding with any mountains, and we are getting pretty well to the Northwest now. Suppose we try to go up?"

This was agreed on as a wise plan, and Dick, who was taking his turn at the wheel, shifted the rudder to send his craft up on a long slant.
