tank. We haven't a
drop left. The vibration must have opened a seam and we've been
spilling our fuel as we went along."

"There goes the other airship!" cried Innis, as the big biplane flashed
by them. They had now crossed Oakland and the bay.

"And the Presido Park is in sight!" yelled Paul, pointing to a big
field, now black with people, for the coming of Dick had been flashed
all over San Francisco and Oakland.

"We can never make it," the young millionaire murmured. "We'll have to
volplane down, but we can't reach the park. Oh, for a gallon of
gasolene! One gallon would do!"

"What's that!" cried Uncle Ezra, coming from his bunk room. "What do
you want of gasolene?"

"To complete the trip," cried Dick. "Ours is all gone! A gallon would
do."

"Then, by hickory, you shall have it!" suddenly cried Mr. Larabee.

"Where can you get it?" demanded Dick. "There isn't a drop aboard!

"Oh, yes there is!" his uncle answered. "Here it is," and he brought
from his room a square, gallon can.

"Great Scott!" cried Dick, as he took it and hurried with it toward the
empty tank. "Where in the world did you get it?"

"I brought it along in my valise to clean the grease spots off my
clothes," answered Uncle Ezra, simply. "I got all oil from my airship.
But I wasn't going to buy a new suit when I could clean my old one."

"Whoop!" cried Dick, with boyish enthusiasm. "This may save the race
for us."

The Abaris had already begun to settle down, but a moment later, as the
motor received the supply of gasolene so Providentially provided, she
shot forward again, her momentum scarcely checked.

On and on she rushed. It was nip and tuck now between her and the
rival airship. The big crowd in the aviation field yelled and shouted
at the sight of the thrilling race.

The other airship seemed to falter and hesitate. The pilot cut off his
motor, but too soon. Dick rushed his craft on, passed the other, and
then, seeing that he had the advantage, he turned off his power, and
volplaned to the landing spot just about fifteen seconds in advance of
his rival. He had beaten in the race at the last minute. But it still
remained to be seen whether he had triumphed over other, and possibly
previous, arrivals.

Out of the Abaris rushed the young millionaire and his friends before
she had ceased rolling over the ground. The other biplane was just
behind them.

An army officer ran out of the crowd of spectators.

"Wh
