“Well,” said Dr. Perkins, as at last they made ready to “turn in,” “all is well that ends well, and to-morrow I have an announcement of some interest to make to you lads. From my inspection of the work done so far on the ‘Sea Eagle,’ as I have decided to christen her, I think that within a few days we can take her on her trial trip.”

“Anchors and aëroplanes!” shouted Pudge, in high glee, “I book passage right now!”

“And I—and I—and I,” came from the others, while Ben Stubbs inquired plaintively if there would be room for him.

CHAPTER IX.—THE FLIGHT OF THE “SEA EAGLE.”

Having already given a brief description of Dr. Perkins’ Sea Eagle, it would be wearisome to dwell in detail on all that was done during the next week to put that craft in shape for the final tests, upon which so much depended. It may be said here, though, that besides a visit paid to Motthaven in an effort to secure the apprehension of the two Daniels, a search was prosecuted for the missing dinghy. Neither mission proved successful.

The Daniels, having discovered that Harry was on board the Betsy Jane after they cut that craft loose, had vanished from the little community. As for the dinghy, it was supposed that they had taken that small craft with them. At any rate, it was impossible to get any news of their whereabouts on shore. This may be attributed to a distinct prejudice felt by the fishing community against the dwellers on Brig Island. Your down-easter is inquisitive to a degree, and the secrecy under which operations on the island were carried on was felt as a distinct affront to the little town. So therefore, although the local authorities promised every co-operation in seeking out the Daniels and punishing them for their outrageous conduct, it may be doubted if the efforts went much further than the mere assurance.

But after all, in the rush of interesting work that was now on hand, the Daniels were almost forgotten. The Betsy Jane had been towed round into the nearer cove, where she could be constantly watched, and the motor boat was used in the operation, the officer of the derelict destroyer having fulfilled his promise to furnish the boys with a new spark plug for the engine in place of the one taken by the marauders.

The morning after Harry’s return to the island Dr. Perkins had laid down a systematic plan of action. Frank and Harry were assigned to aid him in giving the finishing touches to the Sea Eagle, while his son and Billy Barnes were set to work with axes to clear a sort of runway down to the beach. Both Billy and Pudge would much rather have had a hand in the mechanical part of the work, but they pluckily went ahead on their designated duty and stuck to it till a broad path had been cleared from the summit of the island to the margin of the beach.

When this “roadway” through the brush had been cleared, two lines of planking, firmly nailed to stout supports, were run down on each side of it, forming a sort of railway, similar to those from which vessels are launched.

It was down this runway that it was designed to introduce the Sea Eagle to her initial plunge. At last the day arrived when all was complete, and the Sea Eagle was pronounced fit for the test. During the night before this event not one of the boys got more than half his usual allowance of sleep. In fact, it is doubtful if Dr. Perkins enjoyed much more repose.
