"Oh, I want some sort of a load in it," went on the lad. "It won't be a good test unless I have a couple of others besides myself. How about you, Mr. Damon?" for the old gentleman was spending a few days at the Swift homestead.
"Bless my shoe buttons! I'll come!" was the ready answer. "After the experience I've been through in the airship and submarine, nothing can scare me. Lead on, I'll follow!"
"I don't suppose you'll hang back after that; will you, Mr. Sharp?" asked the lad, with a laugh.
"I don't dare to, for the sake of my reputation," was the reply, for the balloonist who had made many ascensions, and dropped thousands of feet in parachutes, was naturally a brave man.
So he and Mr. Damon climbed into the rear seats of the odd-looking electric car, while Tom took his place at the steering wheel.
"Are you all ready?" he asked.
"Let her go!" fired back Mr. Sharp.
"Bless my galvanometer, don't go too fast on the start," cautioned Mr. Damon, nervously.
"I'll not," agreed the young inventor. "I want to get it warmed up before I try any speeding."
