Bruce swung open the big double door and Rogan, one of the reporters for the Woodbridge Journal and the local correspondent for the St. Cloud Call, entered.

"Hello, boys," he shouted good naturedly. "Heard you have a new wrinkle in moth catchers. Is that the machine? Looks mighty businesslike. Is it ready to test? Well, if there isn't Mr. Ford. How are you? What do you think of the scout's invention? How does it work? Whose idea is it. Where—?"

"Oh, goodness gracious, don't ask 'em so fast," said Bruce. "We'll answer them one at a time and explain the machine to you if you'll give us a chance."

"Sure. Excuse me. Go right ahead," said Hogan, his inquisitive blue eyes taking in everything in the room.

Nipper had the honor of describing his own invention, which he did with no little pride. And evidently Rogan was impressed for, after cross examining Mr. Ford and going into the device from every angle, he wrote a two-column story which appeared on the first page of the Journal the following morning. Also he telephoned a story to the St. Cloud paper which the boys read the following afternoon.

As soon as the Academy closed the next day the scouts hurried to headquarters, for they had a great deal to do before they could carry out the test that evening. Two or three attended to the work of removing one of the searchlights from "Old Nanc" and putting it into place on top of the moth catcher, while the rest of the boys strung a temporary line of wire from the headquarters' switchboard to a point about two hundred yards up the road. They intended to conduct the test there and throw the searchlight into the trees on Chipman Hill across the valley.

It was dinner time when the wires were in place and the scouts, after a last look about, all went home to get something to eat and to wait the coming of darkness.

They began to return to headquarters about half past seven. Bruce, Nipper Knapp, and Ray Martin were the first to arrive and, to their surprise, they found at least two dozen people waiting outside of headquarters.

"Well, what does this meant" inquired Bruce of Nipper.

"Well, I guess they read Rogan's story in the Journal. He said we were going to have a test to-night, you know."
