They had secured a boarding place, and had arranged to use an old shed on the outskirts of the town as a “hangar” in which to assemble the parts of their craft. They found everything all right, save that one of the hydroplane floats had been smashed, but a local carpenter had agreed to make another.

The arrival of the lads and the mysterious craft had created no little astonishment in the town, and such a crowd assembled in and about the shed that the motor boys were forced to put up ropes, and hire a man to keep back the throng, so they would have room to work.

“We don’t mind them watching us,” said Jerry; “but we don’t want to step on them all the while, and they will insist on fingering things. First we know, some part will be missing, and then we’ll be in a pretty fix.”

Jim Nestor and Harvey Brill offered their aid in reassembling the motorship, and their services were gladly accepted. One or two mechanics had also been hired to fit the motor and gas machine together, as the boys found themselves pretty well occupied. But, for the most part, the boys did the work themselves. They were familiar with their craft, and knew just how to put it together, having taken it apart several times.

“Is there anything I can do?” inquired Professor Snodgrass, as he entered the shed on the morning when the activities of the lads brought forth the utterances with which I began this chapter. “I’d like to help,” went on the little bald-headed scientist, eagerly.

“No, I guess not,” said Jerry, winking at Ned. “We won’t take you from your researches.”

“Well, then, as long as you don’t want me,” proceeded the “bugologist,” gladly, “I’ll see if I can locate a side-stepping toad. I saw traces of one not long ago.”

“A side-stepping toad!” exclaimed Bob. “That’s a new one.”

“It isn’t good to eat, though, Chunky!” chuckled Ned, taking care to get out of reach of his fat chum.

“But what is it?” asked Bob.
