The race was on in earnest. They were over the Rockies now, and at the present rate of speed it would be only a comparatively short time before they would be at the Pacific coast.

"If I only knew how many landings he had made I wouldn't be so worried," said Dick. "If he's had more than two he's out of it, anyhow, and I wouldn't strain my engine."

"We'd better keep on," advised Mr. Vardon, and they all agreed to this.

Toward the close of the afternoon the Larabee, which they were all sure was the name of the craft in the rear, came on with a rush. Her speed seemed increased by half, and she would, it was now seen, quickly pass the Abaris.

"Well, they're going ahead of us," sighed Dick. "Uncle Ezra did better than I thought he would."

Neither he nor any of the others were prepared for what happened. For suddenly the other airship swooped toward Dick's craft, in what was clearly a savage attack. Straight at the Abaris, using all her speed, came Uncle Ezra's airship.
