"Here we go up!" he suddenly cried. Then, yanking over the lever of the elevating rudder, he sent the Abaris aloft. The rudder for sideway steering worked perfectly, now that repairs had been made.

Up, up into the air soared the big biplane, and from the lake she had left came a blast of saluting whistles from the water-craft that thus paid tribute to a sister vessel.

During the wait on the water Dick had purchased from a passing steamer a supply of gasolene and oil.

"Now we'll have enough so we won't have to land to take on any more," he said. "Our provisions are holding out well, and if nothing happens we can make the trip from here to San Francisco without stop."

"But we still have one landing to our credit if we need it," said Paul.

"Oh, yes, but I hope we don't have to use it," went on Dick. "It will be so much more to our credit if we don't."

The supposition that they were not far from Chicago proved correct, for when they had arisen above the mist that suddenly spread over Lake Michigan, they saw, in the distance, the Windy City.

A course was laid to circle about it, and not cross it, as that might complicate matters, and a little later they were within view of the aviation grounds, of which club Lieutenant McBride was a member.

He had said there might be a meet in progress, and this proved to be so. A number of biplanes and monoplanes were circling about, and the big crowd in attendance leaped to its feet in astonishment at the sight of the young millionaire's new and powerful craft.

It was not the intention of Dick and his chums to stop and make a landing, but they wanted to get some news of other competing craft which might be trying for the big prize. Accordingly a plan was evolved by which this could be done.
