Immediately on the heels of this boom Andy pulled one of the triggers of his double-barrel, so that the report seemed almost merged in with that of the other weapon.
The four boys had jumped to their feet at the flash and report which startled them when Felix fired. And as they turned to dash wildly away and that second shot came, they became madly excited, evidently under the full belief that they were being made targets for a whole battalion of sharpshooters.
Two of them collided, and rolled over on the grass, kicking wildly and scrambling to their feet again, to resume their flight toward the fence, which doubtless seemed three times as distant as when they were creeping toward the stranded aeroplane.
The whole thing was so ridiculous that Andy burst out laughing, and could hardly hold his gun; seeing which the farm hand made bold to snatch it out of his hands, and aiming directly at the place where the fugitives were just then in the act of mounting the fence in their panicky flight, he pulled the trigger.
There was a series of loud yells, which would seem to indicate that a few of the small shot contained in the shells with which the Marlin had been loaded must have reached their mark, and pricked the boys like so many needles would have done.
That was the last seen of them, though for a short time they could be heard running along the hard road, and exchanging excited comments, possibly comparing their injuries.
Then a car was heard to start off with a great deal of bluster, and came dashing along past the farmhouse, though those in it bent low enough to keep any one from discovering who they might be.
Andy did not know whether to be a little angry or not because of what the impetuous Felix had done, but apparently nobody had been seriously hurt; and on the whole, the four "sneaks," as Felix called them, deserved some punishment; so he let it go at that.
There was no further alarm that night. Neither of the guardians of the hydroplane expected any, after the prompt measures that had been taken to inform meddlers of the warm reception they might expect.
All the same, Andy kept up his vigil until sleep almost overpowered him, when he aroused Felix to finish out the night.
