“I wonder where he’s going?” mused Ned.

“No telling,” was Jerry’s opinion. “But come on, let’s get busy. We’ll have to go to Harmolet to-morrow, and see if we can get another cylinder in place of this cracked one.”

There was a trolley line not far from the aviation grounds, and our three boys, catching a car early the next morning, were soon on their way to the city where, so some of the birdmen had assured them, they could easily get a new cylinder, or other parts of their machine or engine. In fact, in anticipation of such calls being made during the meet, one of the automobile dealers in Harmolet had laid in a stock of airship parts.

Passing through a pleasant country, the boys shortly found themselves in a good-sized city. The car was passing through the principal street when, as it went by a bank building, the attention of Jerry and his chum was attracted by a large crowd standing in front. The people overflowed the sidewalk out on the trolley tracks.

“What’s the matter, a run on the bank?” asked Jerry of the conductor.

“Something like that,” was the reply.

“Did the cashier skip off with the funds?” inquired Ned.

“No, the safe was blown open last night, and fifty thousand dollars in cash was taken, besides more in securities. It was quite a sum for the bank to lose, and I guess some of the depositors are nervous. But most of the crowd is there out of curiosity. The police are inside looking for clews. I heard the news on my first trip this morning.”

“Fifty thousand dollars taken!” exclaimed Bob. “That’s a neat sum. Let’s get off here, fellows, and see if we can get a glimpse of the wrecked vault or safe. I’ve got my camera, and maybe they’ll let me take a snap-shot. That would be a picture worth getting.”

“All right,” agreed Jerry. “There’s no special rush about the cylinder.”
