And she did, with the very first effort, beginning to move over the surface of the water in the lee of the tug; then, as Frank hastened to elevate the planes, the airship started to mount and when free from the lake a mighty cheer broke from the lips of those aboard the small vessel, even Casper Blue joining in giving the brave lads their just dues.
Frank carefully started back toward the American side of the lake. He did not know whether the capture had been made on the Canadian side or not, and as the question was never raised, even in the trail of the bank robbers it was never wholly clear in his mind.
When they reached land it was early night; and save that the wind had lulled considerably, they would not have been able to get in for a long time after that. As there was no need of their hurrying homeward, Frank and Andy consented to stay over as the guests of the mayor, who was more than pleased to have the famous Bird boys stop under his roof.
But first Frank made sure to send a message to each of their homes; as well as to Chief Waller, who would have to come on and get the two bold men who had broken into the Bloomsbury bank and about cleaned out the vault; and not content with one haul, were planning to rob the pay-car when it stopped in Bloomsbury to settle with a large number of employees centering there.
Doubtless that must have been a season of considerable excitement in the home town; and the names of Frank and Andy Bird were cheered to the echo by the crowds of town boys Larry and Elephant would lead around, burning red lights and firing off Roman candles purchased with money supplied by Dr. and Professor Bird, the happy fathers of the two young heroes.
On the following day Chief Waller was on hand with one of his men to escort the prisoners back to the town where their latest crime had been committed. Frank had already sent the little camera box with its valuable contents, just as he had received it from Casper Blue, to the president of the bank by express, not caring to hold it any longer in his hands than was absolutely necessary.
About noon, the conditions being favorable, the Bird boys sailed away amidst the cheers of half the little city, and headed directly south on a bee line for home.
Fortunately enough no further adventures overtook them on their way there, and as their coming had been announced they found the whole town in an uproar, and came near being mobbed, such was the desire of every man, woman, boy and girl to have the honor of shaking hands with them.
Percy was on hand too, with a thousand questions concerning the fate of his precious biplane, and bemoaning the fact that he seemed to be the most unlucky fellow who had ever attempted to bring honors to Bloomsbury. But there were precious few who sympathized with him; and everybody knew that all he had to do was to demand that his mother advance the ready cash to buy another flier, and it was sure to be forthcoming.
But there were other lively times in store for Frank and Andy Bird, although neither of them suspected it just then, and believed that a period of calm would likely follow their hydroplane round-up. What the nature of these exploits were the reader who has accompanied us in our voyage through the pages of this book, will learn when he purchases the next story in this series, now on sale under the title of "The Bird Boys' Aeroplane Wonder or, Young Aviators On a Cattle Ranch."
