CHAPTER XXX

  AN ATTACK

  Paul's announcement created considerable excitement. Though they hadcovered a large part of their trip, the young aviators had not yet seenany of their competitors. As a matter of fact, Dick's craft was amongthe first to get away in the trans-continental race. But he had feared,several times, that he might be overtaken by lighter and speediermachines.

  Now, it seemed, his fears were about to be realized. For the bigbiplane that Grit had first spied, could be none other than one ofthose engaged in a try for the twenty-thousand-dollar prize. They werenow nearing the Rockies, and it was not likely that any lone aviatorwould be flying in that locality unless he were after the governmentmoney.

  "Another airship; eh?" cried Dick. "Let me get a look at her! Someonetake the wheel, please."

  "I'll relieve you," offered Lieutenant McBride, whose official dutiesallowed him to do this. "Go see if you can make out who she is, Dick."

  The approaching craft had come up from the rear, and to one side, soshe could not be observed from the pilot-house in front.

  Catching up a pair of powerful field-glasses, Dick went to where Paulstood with Grit, looking out of the celluloid window. By this timesome of the others had also gathered there.

  "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 youngmillionaire, as he adjusted the binoculars to his vision. "But I'msure 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'smy Uncle Ezra's craft," replied Dick, slowly.

  "Great Scott!" cried Paul. "Is it possible? Oh, it's possible allright," Dick made answer, "but I did not think he would really takepart in this race. However, he seems to have done so. I can't makehim out, but that's just the shape of his airship, I can tell by themercury 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.

  "That won't make any difference," the young millionaire said. "Hestarted after we did, and if he gets to San Francisco ahead of us, andwith only two landings, he'll win the prize. That stands to reason.He's making better time than we are."

  Mr. Vardon took the glasses from Dick, and made a long observation.When he lowered them he remarked:

  "I think that is the craft Larson built, all right. And it certainlyis a speedy one. He must have met more favorable conditions, of late,than we did, or he never could have caught up to us."

  "I guess so," agreed Dick. "Now the point is; What can we do?"

  "Speed up--that's the only thing I see to do," came from the aviator."We still have one landing left us, but we don't need to use it unlesswe have to. We have fuel and oil enough for the trip to San Francisco.Speed up, I say, and let's see if we can't get away from him."

  "We've got a heavier machine, and more weight aboard," spoke Dick.

  "Say, can't you drop us off?" cried Paul. "That would lighten you awhole lot. Let Innis and me go!"

  "I'll drop off, too, if it will help any," Larry Dexter offered.

  "And be killed?" asked Mr. Vardon.

  "Not necessarily. You could run the airship over some lake, or river,lower it as close as possible, and we could drop into the water. Wecan all swim and dive. You could drop us near shore, we could get outand make our way to the nearest town. That would leave you with lessload to carry."

  "I wouldn't think of it!" cried Dick.

  "Why not?" asked Innis.

  "In the first place I want my airship to do what I built it for--carrythis party across the continent. If it can't do that, and in time toat least give me a chance for the government prize, I'm going to haveone that can. In the second place, even if your going off would helpme to win, I wouldn't let you take the risk.

  "No, we'll stick together. I think I can get away from Uncle Ezra, ifthat's who is in that biplane. We can run up our speed considerable.We haven't touched the extreme limit yet."

  "Well, if you won't you won't--that settles it," said Paul. "But ifyou're going to speed you'd better begin. He is sure coming on."

  Indeed the other aircraft was rushing toward them at a rapid rate. Ithad been some distance in the rear when first sighted, but now thethree figures aboard were plainly discernable with the naked eye.

  "Speed her up!" called Dick. "We've got to leave him if we can."

  Gradually the Abaris forged on more rapidly. But it seemed as if thosein the other craft were waiting for something like this. For they,too, put on more power, and were soon overhauling the larger airship.

  "They've got an awful lot of force in a light craft," observedLieutenant McBride. "She's over engined, and isn't safe. Even if youruncle gets in ahead of you, Dick, I will still maintain that you havethe better outfit, and the most practical. I don't see how they canlive aboard that frail craft."

  It certainly did not look very comfortable, and afterward Uncle Ezraconfessed that he endured many torments during the trip.

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

  "If I only knew how many landings he had made I wouldn't be soworried," 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 surewas the name of the craft in the rear, came on with a rush. Her speedseemed increased by half, and she would, it was now seen, quickly passthe Abaris.

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

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