But no! A glowing, faintly bluish mass with a comet tail of luminous orange red was slowly proceeding through the pattern of stars!

"Hey, fellows! Wake up!" Tom shouted. He sprang to his feet and unlatched a single point of the star head. Within seconds, Bud and Chow were both wide awake, as excited as Tom. The blue nebulous mass moved closer and closer. The three watchers were speechless with awe.

As the ball of energy descended toward them, it lit up the whole scene. The hillside looked almost as if it were on fire. The earth vibrated, and the air had the sharp smell of ozone. This was followed by a frightening clatter and rumble. The force of the energy was sweeping down rocks, gravel, and shrubbery in a hillside avalanche!

"Look out!" Chow shrieked. "We'll be pulverized in this rock stampede!" He streaked for cover as a huge boulder came plunging straight toward him.

"Hold fast, Bud!" Tom cried. "Nothing's headed our way!"

Steeling his nerves, he grabbed the waiting container and held on grimly. An instant later the glowing mass sharpened and narrowed itself into a snakelike bolt of fire that arced straight into the head of Tom's invention.

Tom gave a yell of triumph and clamped the star point shut, then pushed a button to activate the self-sealing process.

Chow peered out cautiously from behind a clump of rock. The next second, he let out a Texas whoop, bounded from cover like an over-sized gnome, and sent his ten-gallon hat sailing high into the air.

"Yippee!"

Bud cheered too. "The visitor from Planet X has arrived!"
