Andy stared blankly at the fence of the enclosure of the Duske camp. A section of it had been broken down, and the gate left open in removing the airship. Of a sudden he stared eagerly. Some one had come into the enclosure.

The intruder was evidently some casual sight-seer, a boy. His hands were in his pockets, and he strolled about as if curiously inspecting everything that came under his notice. He cast a careless glance at the tent, and was proceeding on his way towards the main aviation field, when Andy gave a great start.

“Silas—Silas Pierce!” he shouted, ignoring discovery by the cook.

Andy’s heart was thumping like a trip-hammer. It seemed as if on the verge of the blackest despair a bright star of hope had risen on the horizon. He had recognized the intruder with surprise, but with gladness as well.

It was his companion of the goose trip, the son of Mr. Pierce—the farmer Silas—whom Andy had last seen at the Collins place, the farm he had visited the day previous. Silas wore a brand-new suit of clothes. He suggested the typical country boy, with some loose cash in his pocket, enjoying a brief holiday to the utmost.

“Hey!” exclaimed Silas, with a startled jump, his eyes goggling all about, and unable to trace the source of the challenge.

Andy uttered a groan. At the moment the breeze let down, and the canvas dropped, shutting him in and Silas out. Then a puff of wind came and lifted the flap again.

“Here, here, Silas!” called out Andy in tones of strained suspense. “Quick—help!”

“I vum!” gasped the farmer boy, staring blankly at what he saw of Andy. “Who is it? And—I say, you’re dad’s great friend, the Nelson boy!”

Silas had advanced, and took in the situation, and recognized Andy slowly.
