Wakefield Damon glanced at Mr. Swift. The inventor was oblivious to his surroundings, and was busy figuring away on some paper. He seemed even to have forgotten the presence of the eccentric autoist.  
"I don't want father to hear about the men," went on Tom, in a low tone. "If he hears that Happy Harry and his confederates are in this vicinity, he'll worry, and that doesn't agree with him. But are you sure the men you saw are the same ones who stole the turbine model?"
 
"Very certain," replied Mr. Damon. "I had a good view of them as I came from the bank, and I was surprised to see them, until I remembered that they were out of jail."
 
"But why do you think they pursued you?"
 
"Bless my eyes! I can't say. Perhaps they weren't after me at all. I may have imagined it, but they certainly hurried off in their auto as soon as I left the bank, after leaving my money there. I'm glad I deposited it before I saw them. I was so nervous, as it was, that I couldn't steer straight. It's too bad, the way I've damaged your house."
 
"That doesn't matter. But how about the trip in the airship? I hope you meant it when you said you would go."
 
"Of course I did. I've never traveled in the air, but it can't be much worse than my experience with my motor-cycle and the auto. At least I can't run up any stoop, can I?" and Mr. Damon looked at Mr. Sharp.
 
"No," replied the aeronaut, as he scratched his head, "I guess you'll be safe on that score. But I hope you won't get nervous when we reach a great height."
 
"Oh, no. I'll just calm myself with the reflection that I can't die but once," and with this philosophical reflection Mr. Damon went back to look at the auto, which certainly looked odd, stuck up on the veranda.
 
"Well, you'd better make arrangements to go with us then," went on Tom. "Meanwhile I'll see to getting your car down. You'll want to send it home, I suppose?"
 
"No, not if you'll keep it for me. The fact is that all my folks are away, and will be for some time. I don't have to go home to notify them, and it's a good thing, as my wife is very nervous, and might object, if she heard about the airship. I'll just stay here, if you've no objection, until the Red Cloud sails, if sails is the proper term."
 
"'Sails' will do very well," answered Mr. Sharp. "But, Tom, let's see if you and I can't get that car down. Perhaps Mr. Damon would like to go in the house and talk to your father," for Mr. Swift had left the piazza.
 
The eccentric individual was glad enough not to be on hand when his car was eased down from the veranda and disappeared into the house. Tom and Mr. Sharp, with the aid of Garret Jackson, then released the auto from its position. They had to take down the rest of the broken railing, and their task was easy enough. The machine was stored in a disused shed, and Mr. Damon had no further concern until it was time to undertake the trip through the air.
 
"It will fool those men if I mysteriously disappear," he said, with a smile. "Bless my hat band, but they'll wonder what became of me. We'll just slip off in the Red Cloud, and they'll never be the wiser."
 
"I don't know about that," commented Tom. "I fancy they are keeping pretty close watch in this vicinity, and I don't like it. I'm afraid they are up to some mischief. I should think the bank authorities would have them locked upon suspicion. I think I'll telephone Ned about it."
 
He did so, and his chum, in turn, notified the bank watchman. But the next day it was reported that no sign of the men had been seen, and, later it was learned that an auto, answering the description of the one they were in, had been seen going south, many miles from Shopton.
 
The work of preparing the Red Cloud for the long trip was all but completed. It had been placed back in the shed while a few more adjustments were made to the machinery.
 
"Bless my eyelashes!" exclaimed Mr. Damon, a few days before the one set for the start, "but I haven't asked where we are bound for. Where are we going, anyhow, Mr. Sharp?"
 
"We're going to try and reach Atlanta, Georgia," replied the balloonist. "That will make a fairly long trip, and the winds at this season are favorable in that direction."
 
"That suits me all right," declared Mr. Damon. "I'm all ready and anxious to start."
 
It was decided to give the airship a few more trials around Shopton before setting out, to see how it behaved with the car heavier loaded than usual. With this in view a trip was made to Rocksmond, with Mr. Swift, Mr. Damon and Ned, in addition to Mr. Sharp and Tom, on board. Then, at Tom's somewhat blushing request, a stop was made near the Seminary, and, when the pupils came tro............
